Clearbit vs Lusha: One Is an API, the Other Is a Prospecting Tool: Choose Accordingly

Quick Verdict

Pick Clearbit (Breeze Intelligence) when engineering or RevOps owns the buying decision and you need API-based firmographic data piped into forms, CRMs, or scoring models. Pick Lusha when individual SDRs need a browser extension to surface phone numbers and emails on LinkedIn during active prospecting. The two tools target different buyers inside the same company.

Overview of Each Product

Both companies launched within a year of each other and took opposite routes to market. Clearbit chased developers and stayed API-only for years. Lusha shipped a Chrome extension and optimized for SDR usability. The strategies explain the gap in pricing, onboarding, and user base today.

Clearbit (now HubSpot Breeze Intelligence)

Clearbit was founded in 2015 by Alex MacCaw in San Francisco. HubSpot acquired it in November 2023 (reported at ~$150M by Axios) and folded it into the Breeze Intelligence product line. It remains API-first but is increasingly gated behind HubSpot subscriptions.

Lusha

Lusha was founded in 2016 by Assaf Eisenstein and Yoni Tserruya in Tel Aviv. It raised a $205M Series B in 2021 at a $1.5B valuation (per Calcalist) and reports over 1 million users across 273,000 companies. The Chrome extension remains its primary entry point.

Feature-by-Feature Breakdown

Four dimensions separate these tools in practice: API depth, contact data quality, user experience, and integration surface. On each one a different product wins, which is why some teams run both instead of picking a single stack.

Enrichment API

Clearbit wins on API maturity. Its reveal, enrichment, and prospector endpoints have been documented since 2015 and power thousands of marketing stacks doing real-time form enrichment. Lusha ships an API too, but it is newer, rate-limited, and built primarily for Zapier-style workflows rather than high-volume production use.

Contact Data Quality

Lusha leads on direct-dial mobile coverage. Its dataset draws from contributor networks, with accuracy reported at 81% in Lusha's 2024 data report. Clearbit's strength is firmographic breadth (revenue range, tech stack, employee count, funding round) rather than personal mobile verification.

User Experience

Lusha is friendlier for individual SDRs. The Chrome extension surfaces contact data inline on LinkedIn with one click, no setup required. Clearbit has no equivalent browser surface post-acquisition; using it now typically means calling the API or working inside HubSpot, which requires engineering support.

Integrations

Clearbit ships bi-directional sync with HubSpot by default (same vendor) plus Marketo and Segment connectors. Lusha offers connectors for HubSpot, Salesforce, Outreach, and Salesloft per its integrations catalog, though setup depth varies by plan tier.

Pricing and Total Cost of Ownership

Clearbit restructured pricing after the HubSpot acquisition and now sells credits tied to Breeze Intelligence. Lusha kept a per-seat SaaS model with a permanent free tier. The two cost structures reward different team shapes, which matters more than the headline numbers for a real buying decision.

Annual TCO at three team sizes. For 5 SDRs: Lusha Pro runs ~$1,740/yr, equivalent Clearbit credit volume ~$3,600/yr. For 25 users: Lusha ~$8,700/yr, Clearbit enterprise typically from ~$18,000/yr. For 100 users: Lusha ~$34,800/yr, Clearbit enterprise routinely $60,000+/yr. Lusha is cheaper at every tier, though this ignores Clearbit's form-enrichment and scoring upside.

Pros and Cons

Each tool has a real weakness worth naming. Neither is the right fit for every team, even inside its home category.

Clearbit

Pros: deepest firmographic and technographic API in the category; proven at scale for form shortening and lead scoring; tight bundle for HubSpot customers. Cons: free tier removed post-acquisition; non-technical users need engineering help; increasingly locked into the HubSpot ecosystem.

Lusha

Pros: permanent free tier with 5 monthly credits; strong mobile phone coverage for US and EU targets (81% accuracy per Lusha's 2024 report); zero setup time. Cons: credit caps hurt high-volume outbound teams; firmographic data thinner than Clearbit or ZoomInfo; API is newer and less battle-tested.

Who Should Choose What?

The decision comes down to who inside your company touches the data daily. An engineer calling an API has different needs than an SDR flipping through LinkedIn tabs. Match the tool to the operator, not the logo on the slide.

Choose Clearbit if...

Your team has an engineer or RevOps lead, you run HubSpot, and you want enrichment behind the scenes. Example: Priya, Head of Marketing Ops at a 120-person Series B SaaS on HubSpot Enterprise, wants to cut form fields from 9 to 3 and auto-enrich the rest.

Choose Lusha if...

You lead an SDR team that prospects on LinkedIn daily and needs fast contact lookups. Example: Rohit, SDR Manager at a Series A cybersecurity startup. His team of 6 works 80 accounts per week and needs mobile numbers to book demos before the quarter closes.

Final Recommendation

Do not pick between Clearbit and Lusha on price alone. Pick based on who inside your company touches the data daily. If engineering touches it, Clearbit is the better fit. If an SDR touches it, Lusha wins. Teams running both inbound and outbound motions often run both tools and accept the overlap.
