TL;DR — Rodz, Lusha, Kaspr and Apollo all help B2B teams find contact data and identify sales opportunities. They are not interchangeable. Rodz is an API-first signals and enrichment platform with 14 intent signal types, 12 enrichment endpoints, real-time webhooks, MCP support and a proprietary Balance scoring model. Lusha focuses on contact data and buyer intent at the browser-extension level. Kaspr specializes in LinkedIn-based phone number and email extraction. Apollo combines a contact database with sequencing and outreach tools. This guide breaks down each platform feature by feature so you can decide which one fits your stack, your workflow and your budget.
What This Comparison Covers
Choosing a B2B enrichment tool is not a feature checkbox exercise. The right choice depends on what you need the data for, how you plan to consume it, and where it fits inside your existing workflow.
This article compares four platforms that B2B sales and marketing teams regularly evaluate side by side: Rodz, Lusha, Kaspr and Apollo. Each one occupies a slightly different position in the market. Some overlap exists, especially around contact enrichment, but the differences in signal coverage, API depth, real-time capabilities and scoring models are significant.
We structured this comparison to be practical. Instead of vague feature lists, we cover specific capabilities: how many signal types each platform supports, what enrichment endpoints they expose, whether they offer webhooks, how they handle lead scoring, and what their API architecture looks like. We also address pricing philosophy and typical use cases so you can map each tool to your own situation.
This is a fair comparison. We built Rodz, so naturally we know it best. But we are not going to pretend the other tools have no strengths. Lusha, Kaspr and Apollo are solid products with millions of users. The goal here is to help you understand where each one shines and where it falls short, so you make an informed decision.

Prerequisites
To get the most out of this comparison, you should have:
-
A clear Ideal Customer Profile (ICP). Know who you are selling to, which industries, company sizes, geographies and personas matter to you. This determines which signals and enrichment fields are relevant.
-
A defined workflow. Are you enriching leads inside a CRM? Running outbound sequences? Building automated pipelines with Make or n8n? The answer shapes which tool fits best.
-
Basic API familiarity (optional but helpful). Several of the differences between these platforms only become visible at the API level. If you are evaluating tools for a technical integration, understanding REST APIs and JSON will help you follow the comparison.
-
An understanding of intent signals. If you are new to the concept, read How to Configure Your First Intent Signal with the Rodz API for context on what signals are and why they matter.
Platform Overview: Rodz
Rodz is an API-first B2B intelligence platform built around two pillars: intent signals and data enrichment.
On the signals side, Rodz monitors 14 distinct signal types that cover hiring activity, financial events, people movements, social engagement and market opportunities. Each signal type can be configured with filters (industry, geography, company size, seniority, volume thresholds) to surface only the events that match your ICP. Signals are delivered in real time through webhooks or consumed via the signal feed API.
On the enrichment side, Rodz exposes 12 API endpoints that cover company enrichment (firmographic, financial and SIRENE data), contact enrichment (profile lookup, email finder, reverse email), bulk operations, technographic data, social profiles, job postings and news. For a deep dive into contact enrichment, see B2B Contact Enrichment: Find and Verify Emails with the Rodz API. For company enrichment, see Company Enrichment: Firmographic, Financial and SIRENE Data via the Rodz API.
Rodz also includes two features that none of the competitors in this comparison offer: MCP (Model Context Protocol) support, which allows AI agents and LLM-powered tools to interact with the Rodz API natively, and Balance scoring, a proprietary lead-scoring model that combines signal frequency, recency and relevance into a single composite score.
The platform is designed for teams that want to build custom workflows. There is no built-in sequencing tool or chrome extension. Rodz is the data and intelligence layer. You plug it into your CRM, your outreach tool, your automation platform, or your custom application via the API.
Key Rodz Strengths
- 14 intent signal types with granular filtering
- 12 enrichment endpoints covering contacts, companies, technographics, social, jobs and news
- Real-time webhooks with HMAC-SHA256 signature verification and automatic retries
- MCP support for AI-native integrations
- Balance scoring for prioritizing leads based on signal density
- Bulk enrichment for processing up to 100 records per request
- Cursor-based pagination for efficient data consumption
- 100 requests/minute rate limit with clear headers and retry guidance
Platform Overview: Lusha
Lusha is a B2B contact data platform focused on providing verified email addresses, phone numbers and company data. It started as a browser extension for LinkedIn and has expanded into a broader platform with a database of over 100 million business profiles.
Lusha’s core product revolves around its Chrome extension, which overlays contact data on LinkedIn profiles and company websites. Sales reps use it to grab direct dials and email addresses while browsing LinkedIn. The platform also offers a web application where you can search and filter contacts by title, industry, company size, location and other criteria.
On the enrichment side, Lusha provides APIs for contact and company lookup, but the endpoint depth is more limited than what Rodz offers. Lusha focuses on core contact fields: email, phone, job title, company. It does not expose separate endpoints for technographic data, SIRENE registry lookups, social profiles or news aggregation.
Lusha introduced “Buyer Intent” signals in recent years, powered by partnerships with third-party intent data providers. These signals identify companies that are actively researching topics related to your product category. The signal types are broader and less granular than what Rodz offers. Lusha does not break intent down into 14 distinct categories. Instead, it provides a general intent score based on content consumption patterns.
Lusha does not support webhooks natively. Integrations are built through its CRM connectors (Salesforce, HubSpot, Outreach, Salesloft) and its Zapier integration. There is no MCP support and no equivalent to Balance scoring.
Key Lusha Strengths
- Large contact database (100M+ profiles) with direct phone numbers
- Chrome extension for instant LinkedIn enrichment
- CRM integrations with Salesforce, HubSpot and major outreach tools
- Buyer intent data through third-party partnerships
- Compliance-focused with GDPR and CCPA certifications
- Easy to adopt for non-technical sales teams
Platform Overview: Kaspr
Kaspr is a LinkedIn-focused prospecting tool that specializes in extracting phone numbers and email addresses from LinkedIn profiles. It is built primarily as a Chrome extension with a companion web application.
Kaspr’s value proposition is straightforward: visit a LinkedIn profile, click the extension, get the person’s phone number and email. The tool has a strong reputation for phone number accuracy, particularly in Europe, which makes it popular with SDR teams running call-heavy outbound motions.
Kaspr offers basic enrichment capabilities through its API, but the scope is narrow. You can look up contacts by LinkedIn URL and get back email and phone data. There are no company enrichment endpoints, no technographic lookups, no SIRENE data, and no news or job posting endpoints.
Kaspr does not have an intent signals product. It is purely a contact data extraction tool. There are no webhooks, no MCP support, and no lead scoring model. The platform integrates with CRMs and outreach tools (HubSpot, Pipedrive, Salesforce, Lemlist, Ringover) through native connectors.
Kaspr also includes a LinkedIn automation layer that lets you build prospecting sequences directly from LinkedIn: profile visits, connection requests and messages. This makes it more of an all-in-one LinkedIn prospecting tool than a data platform.
Key Kaspr Strengths
- High phone number accuracy in European markets
- Simple LinkedIn workflow: visit profile, click, get data
- LinkedIn automation built into the platform
- Affordable pricing for small teams and individual SDRs
- Native integrations with Lemlist, Pipedrive and other outreach tools
- Fast onboarding with no technical setup required
Platform Overview: Apollo
Apollo.io is the most feature-complete platform in this comparison from a pure feature count perspective. It combines a B2B contact database (270M+ contacts), email sequencing, dialer, task management, analytics, and basic intent signals into a single product.
Apollo’s contact database is its marquee feature. It claims over 270 million contacts and 60 million companies with email addresses, phone numbers, job titles, company data and technographic information. The platform offers both a web interface and an API for searching, filtering and enriching records.
On the enrichment side, Apollo provides endpoints for contact and company lookup, but the API is designed primarily to serve the Apollo database rather than act as a standalone enrichment layer. You search Apollo’s database for matches. The model is closer to a search engine than a real-time enrichment API. Apollo does not offer separate endpoints for financial data, SIRENE registry, news or social profiles.
Apollo introduced intent signals through a partnership with Bombora, which provides topic-level intent data based on content consumption across a cooperative of B2B publishers. Like Lusha, Apollo’s intent signals are topic-based rather than event-based. You see that a company is researching “CRM software” or “cloud migration,” but you do not get granular event types like fundraising rounds, M&A activity, job republications or public tenders.
Apollo offers webhook support for some events (notably contact and account updates), but the webhook system is less flexible than Rodz’s. There is no MCP support. Apollo has its own lead scoring model, but it is based on engagement with Apollo sequences (email opens, clicks, replies) rather than external intent signals.
Key Apollo Strengths
- Massive contact database (270M+ contacts, 60M+ companies)
- All-in-one platform: database, sequences, dialer, analytics
- Bombora intent data for topic-level buyer intent
- Built-in email sequencing with A/B testing and analytics
- Generous free tier for individual users
- Strong API for database search and contact export

Signal Coverage: 14 Types vs Topic-Based Intent
This is where the platforms diverge most dramatically.
Rodz supports 14 event-based signal types, each representing a specific business event that you can filter, configure and act on independently:
- Job offers — new job postings by target companies
- Republished job offers — reposted positions indicating urgency
- Recruitment campaigns — coordinated multi-role hiring pushes
- Fundraising — seed through growth equity rounds
- Mergers and acquisitions — M&A activity
- Company registration — newly registered businesses
- Job changes — decision-makers moving between companies
- Competitor relationships — hiring from or losing people to competitors
- Social mentions — brand mentions on social platforms
- Social reactions — engagement patterns on company content
- Influencer engagement — interactions from industry influencers
- Company page engagement — changes in page-level engagement metrics
- Company followers — follower growth trends
- Public tenders — published RFPs with defined budgets and timelines
Each of these signal types can be filtered by industry, geography, company size, seniority level and custom thresholds. You can run multiple signal configurations simultaneously, and each one delivers results through the signal feed API or via webhooks.
Lusha and Apollo take a fundamentally different approach. They use topic-based intent data, which tells you that a company is “researching” a particular topic (like “project management software” or “cloud security”) based on content consumption patterns across a network of B2B publisher sites. This data comes from third-party providers (Bombora in Apollo’s case, a similar partnership for Lusha).
Topic-based intent is useful, but it has limitations:
- It is aggregated and anonymized. You know that “Company X is researching Topic Y,” but you do not know which person at the company is doing the research, what stage they are at, or what triggered the interest.
- It is delayed. Content consumption data is typically batched and processed weekly. Rodz signals, by contrast, are delivered in real time via webhooks.
- It cannot capture non-digital events. A funding round, an M&A deal, a public tender, or a leadership change are real-world business events that topic-based intent data simply does not detect. These events are often the strongest buying signals available.
- It is hard to filter granularly. You cannot say “show me companies that just republished a senior engineering role in France for the third time.” With Rodz, you can.
Kaspr does not offer any signals product at all. It is purely a contact data extraction tool.
When Topic-Based Intent Is Enough
Topic-based intent works well when your product maps directly to a research topic, when you operate in a market where digital research precedes every purchase decision, and when you have enough volume to work with probabilistic signals. Enterprise SaaS companies selling to large organizations often find Bombora-style intent data useful because their buyers go through long research cycles.
When Event-Based Signals Win
Event-based signals are stronger when timing matters, when you need to reach people during a specific window of opportunity, and when the buying trigger is a business event rather than a research topic. If you sell to companies that just raised funding, just hired a new CTO, or just published a public tender, event-based signals give you a direct line to that opportunity. The Rodz signal model is built for this scenario.
Enrichment Endpoints: Depth Matters
The number and specificity of enrichment endpoints determines how much you can learn about a prospect without leaving your workflow.
Rodz: 12 Endpoints
Rodz exposes 12 enrichment endpoints, each with a specific purpose:
| Endpoint | Purpose |
|---|---|
GET /enrichment/company | Enrich a company by domain |
GET /enrichment/company/{id} | Retrieve a previously enriched company |
POST /enrichment/company/bulk | Enrich up to 100 companies per request |
GET /enrichment/contact | Enrich a contact by email or LinkedIn URL |
GET /enrichment/contact/{id} | Retrieve a previously enriched contact |
POST /enrichment/contact/bulk | Enrich up to 100 contacts per request |
GET /enrichment/company/{id}/contacts | List contacts at an enriched company |
GET /enrichment/company/{id}/signals | Get signals associated with a company |
GET /enrichment/company/{id}/technographics | Get a company’s technology stack |
GET /enrichment/contact/{id}/social | Get social profiles for a contact |
GET /enrichment/jobs | Search job postings by company or criteria |
GET /enrichment/news | Search news articles by company or topic |
This granularity means you can build very specific workflows. For example, you might enrich a company, check its technology stack to confirm it uses a competitor’s product, pull the latest news to find a conversation starter, then enrich the VP of Engineering’s contact data, all through the API without switching tools.
For the full endpoint reference including parameters, response schemas and error codes, see the API Reference.
Lusha: 4-5 Endpoints
Lusha’s API offers contact lookup by email or LinkedIn URL, company lookup by domain, and bulk CSV enrichment. The API returns core fields (email, phone, name, title, company) but does not break out into specialized endpoints for technographic data, financial data, social profiles or news. If you need those data points, you have to supplement Lusha with another tool.
Kaspr: 2-3 Endpoints
Kaspr’s API is minimal. It offers a contact lookup endpoint and a basic search. The focus is on returning email and phone data from LinkedIn URLs. There is no company enrichment layer, no technographic data, and no bulk API endpoint.
Apollo: 6-8 Endpoints
Apollo’s API is more capable than Lusha’s or Kaspr’s. It includes endpoints for people search, organization search, contact enrichment, and bulk operations. Apollo also returns technographic data as part of its company records, though not through a dedicated endpoint. The API is primarily designed to search Apollo’s database rather than enrich arbitrary records in real time. This distinction matters: if a company or contact is not in Apollo’s database, the enrichment call returns nothing. Rodz enriches from live data sources, so coverage is not limited to a pre-built database.
Webhooks: Real-Time vs Polling
Webhooks are the mechanism that separates real-time intelligence from batch data pulls. If your workflow depends on acting fast, within minutes of a signal firing, webhooks are essential.
Rodz Webhooks
Rodz offers a full webhook system with four API endpoints for managing webhook registrations (GET, POST, PUT, DELETE /webhooks). When a signal triggers or an enrichment job completes, Rodz sends a POST request to your registered URL with a JSON payload containing the event data.
Security is handled through HMAC-SHA256 signatures. Every webhook payload includes an X-Rodz-Signature header that you can verify against your signing secret. Failed deliveries are retried up to 5 times with exponential backoff (30 seconds, 2 minutes, 10 minutes, 1 hour, 6 hours).
This means you can build workflows that react to business events in seconds. A funding round fires, a webhook hits your endpoint, your automation enriches the company, identifies the right contact, and creates a task in your CRM, all without anyone polling an API or checking a dashboard.
Lusha
Lusha does not offer native webhooks. Integrations are handled through CRM connectors and Zapier. This means you cannot build real-time event-driven workflows directly. You can use Zapier triggers with polling intervals, but the minimum polling interval is typically 5-15 minutes, which is not true real-time.
Kaspr
Kaspr does not offer webhooks. Data flows from Kaspr to other tools through its native CRM integrations or manual CSV exports.
Apollo
Apollo offers limited webhook support. You can subscribe to some events (primarily contact and account updates within Apollo), but the webhook system is not as comprehensive as Rodz’s. Apollo’s webhooks are focused on internal platform events rather than external intent signals.
MCP Support: AI-Native Integration
MCP (Model Context Protocol) is an open protocol that allows AI agents, LLM applications and automated reasoning tools to interact with external APIs in a structured, semantic way. It is particularly relevant for teams building AI-powered sales workflows, autonomous prospecting agents, or LLM-based research tools.
Rodz supports MCP natively. This means an AI agent can query Rodz for signals, enrich companies and contacts, configure signal filters and consume webhook events through a standardized protocol that the agent understands semantically. Instead of writing custom API integration code for your AI agent, you point it at the Rodz MCP endpoint and it discovers available capabilities automatically.
This is a forward-looking differentiator. As more sales and marketing workflows incorporate AI agents (for lead research, personalized outreach drafting, account prioritization), MCP support becomes a significant advantage. An AI agent connected to Rodz can autonomously monitor signals, research companies and prepare briefings without human-written integration code.
Neither Lusha, Kaspr nor Apollo offers MCP support. Integrating these tools with AI agents requires custom API wrappers and prompt engineering to map their endpoints into a format the agent can use.
Balance Scoring: Signal-Weighted Lead Prioritization
Not all leads are equal, and not all signals carry the same weight. Balance scoring is Rodz’s proprietary model for turning raw signal data into a prioritized lead list.
The Balance score combines three dimensions:
- Signal frequency. How many signals has this company triggered recently? A company that triggered five different signal types in the last month is more interesting than one that triggered a single signal six months ago.
- Signal recency. When did the signals fire? Recent signals carry more weight because the buying window is still open. A funding round from last week matters more than one from last quarter.
- Signal relevance. How closely do the triggered signals match your configured ICP? A signal that hits all your filters scores higher than one that only matches partially.
These three dimensions are combined into a single numeric score that you can use to sort and prioritize your pipeline. The result is a ranked list of companies where the top entries are the ones most likely to be in an active buying cycle.
How Competitors Handle Scoring
Lusha provides a generic intent score based on topic-based content consumption. It tells you that a company has “high intent” for a particular topic, but it does not factor in event-based signals, recency weighting or ICP alignment.
Kaspr does not offer any scoring model. It provides contact data without prioritization.
Apollo scores leads based on engagement with your outreach sequences (email opens, clicks, replies, meetings booked). This is useful once you have started reaching out, but it does not help you prioritize before outreach. You need to already be emailing someone to know if they are engaged. Rodz’s Balance scoring works upstream, prioritizing which companies to contact in the first place.

Combining Tools: The Realistic Scenario
In practice, many B2B teams use more than one tool. The most common combinations we see:
Rodz + outreach tool. Use Rodz for signals and enrichment, then push prioritized leads into Lemlist, La Growth Machine, or another sequencing tool. This gives you event-based signal intelligence and deep enrichment on the data side, paired with a purpose-built tool for multi-channel outreach.
Rodz + CRM. Connect Rodz webhooks to your CRM (Pipedrive, HubSpot, Salesforce) using Make or n8n. When a signal fires, the automation enriches the company, creates or updates the CRM record, and assigns a task to the right rep. This is the most common production setup for Rodz users.
Kaspr + Rodz. Some teams use Kaspr for quick LinkedIn phone number extraction during manual prospecting, while running Rodz in the background for automated signal monitoring and enrichment. The tools do not conflict because they serve different moments in the workflow.
Apollo for prospecting, Rodz for intelligence. A few teams use Apollo’s large database for initial list building, then enrich and prioritize those lists through Rodz’s signal and enrichment APIs. This combines Apollo’s breadth with Rodz’s depth.
The key principle is: match the tool to the job. A browser extension is great for individual reps doing manual research. An API-first platform is necessary for automated, scalable workflows. A sequencing tool handles the outreach. Trying to force one tool to do everything usually means doing everything poorly.
Frequently Asked Questions
Is Rodz a Replacement for Lusha?
It depends on how you use Lusha. If you rely on Lusha’s Chrome extension for quick LinkedIn lookups during manual prospecting, Rodz is not a direct replacement because it does not have a browser extension. If you use Lusha primarily for its API-based enrichment or its buyer intent data, Rodz replaces and expands on both of those capabilities with more endpoints, more signal types and real-time webhooks.
Many teams keep Lusha for the extension and add Rodz for the automated intelligence layer. The two can coexist without conflicts.
Does Rodz Have a Chrome Extension?
No. Rodz is API-first by design. The platform is built for programmatic access, automated workflows and system-to-system integrations. If you need a browser extension for manual lookups, pair Rodz with a tool like Kaspr, Lusha or Surfe that specializes in that interaction model.
How Does Rodz’s Data Accuracy Compare to Apollo’s Database?
The two platforms use fundamentally different data models. Apollo maintains a large pre-built database that is periodically refreshed. When you enrich a contact through Apollo, you are querying that database. If the record is stale or missing, you get stale or no data.
Rodz enriches from live data sources at the time of the API call. This means the data tends to be fresher, but coverage depends on the availability of live sources for that specific company or contact. For well-known companies and active LinkedIn profiles, Rodz enrichment is highly accurate. For very small or obscure companies, Apollo’s pre-built database may have better coverage simply because it has been accumulating records for longer.
The best approach is to test both tools against your actual target accounts and compare hit rates and accuracy for your specific ICP.
Can I Use Rodz and Apollo Together?
Yes, and some teams do. A common pattern is to use Apollo for initial list building (leveraging its large database and search filters) and then enrich those leads through the Rodz API for deeper data (technographics, financial data, SIRENE) and signal monitoring. The Rodz enrichment endpoints accept standard identifiers (domain, email, LinkedIn URL) so you can pipe Apollo exports directly into Rodz.
What Is Balance Scoring and Do Competitors Have It?
Balance scoring is Rodz’s proprietary lead prioritization model. It combines signal frequency, recency and relevance into a single composite score that tells you which companies in your pipeline are most likely to be in an active buying cycle.
Lusha has a simpler intent score based on topic-level content consumption. Apollo has engagement scoring based on sequence interactions (opens, clicks, replies). Neither approach factors in real-world business events the way Balance scoring does.
If your outbound strategy is signal-driven, meaning you reach out to companies because something happened (they raised money, they are hiring, a key person changed roles), Balance scoring is the most useful prioritization model because it is built directly on top of the signal data.
What Is MCP and Why Does It Matter?
MCP stands for Model Context Protocol. It is an open standard that lets AI agents and LLM-based tools discover and interact with external APIs without custom integration code. When Rodz exposes its capabilities through MCP, an AI agent can autonomously query signals, run enrichment, and consume events.
This matters because B2B sales workflows are increasingly incorporating AI. Teams are building agents that research accounts, draft personalized emails, and prioritize leads automatically. MCP support means Rodz integrates natively with these AI-powered workflows instead of requiring custom API wrappers.
None of the other platforms in this comparison support MCP today.
How Do Pricing Models Compare?
Each platform uses a different pricing structure:
- Rodz uses credit-based pricing. Each API call (signal query, enrichment request) consumes credits. Plans scale based on credit volume and the number of active signal configurations. All plans include API access.
- Lusha uses a seat-based model with credit allocations per user per month. Higher tiers unlock more credits and additional features like buyer intent data. The Chrome extension is available on all plans.
- Kaspr uses a seat-based model with monthly credit limits for phone and email reveals. Plans differ in the number of credits, export options and integration access.
- Apollo offers a generous free tier (limited credits per month) and paid plans that increase credit limits, unlock advanced features (intent data, dialer, advanced analytics) and add seats.
Direct price comparison is difficult because the credit systems are not equivalent. One Rodz credit is not the same as one Lusha credit. The practical approach is to estimate your monthly usage (how many enrichments, how many signal queries, how many seats) and request pricing from each vendor for that specific volume.
Is the Rodz API Difficult to Integrate?
The Rodz API follows REST conventions, uses JSON, and is documented with request/response examples for every endpoint. If you have integrated any modern API (Stripe, Twilio, HubSpot), the Rodz API will feel familiar.
For teams without in-house developers, Rodz integrates with no-code automation platforms like Make and n8n. You can build complete signal-to-CRM workflows without writing code.
The full API documentation is available at https://api.rodz.io/docs. For a guided walkthrough of authentication and first requests, start with the Getting Started guide.
Conclusion
Rodz, Lusha, Kaspr and Apollo are different tools built for different priorities. Rodz is the strongest choice when you need deep, event-based intent signals, a comprehensive enrichment API, real-time webhooks, AI-native integration through MCP, and signal-weighted lead scoring. Lusha wins on ease of use for non-technical teams and direct-dial phone coverage. Kaspr is the go-to for LinkedIn-centric, call-heavy prospecting on a budget. Apollo provides the broadest all-in-one feature set with a massive contact database and built-in sequencing.
The question is not which tool is “best.” It is which tool matches the way you work.
If your workflow is API-first, signal-driven and built on automation, explore the Rodz API documentation and test it against your ICP. The platform is designed to integrate, not to replace your entire stack.
