The answer, as recorded

# Lead enrichment tools for startups Here's what I'd actually recommend, roughly in the order I'd try them: **1. Apollo.io - start here.** Best price-to-value for an early-stage team. It's an all-in-one: contact database, enrichment, and sequencing in one tool, with its own data (so no separate per-provider bills). Free tier to test, ~$49/seat/mo to start. The tradeoff is data quality - independent tests put verified mobile accuracy around 65-80%, and it's weaker outside North America. Fine for broad discovery, less so for a short high-value list. ([Apollo vs Clay pricing](https://www.cleanlist.ai/blog/2026-03-19-clay-vs-apollo), [Cognism vs Lusha vs Apollo](https://appendment.com/blog/cognism-vs-lusha-vs-apollo/)) **2. Clay - when you outgrow one vendor's data.** It's a waterfall orchestrator: hit provider A, fall back to B, then C, and only pay for the hit. Also where you'd run AI research steps (scrape a site, classify an ICP fit) that no single database does. They overhauled pricing March 2026 - Free ($0, 100 data credits, 200-row cap), Launch $185/mo, Growth $495/mo, and data costs dropped 50-90%. Worth it once you have real volume; the free plan only prototypes. ([Clay pricing 2026](https://www.warmly.ai/p/blog/clay-pricing), [Landbase breakdown](https://www.landbase.com/blog/clay-pricing)) **3. Cognism - if you sell into Europe or need phones that connect.** Their phone-verified "Diamond Data" is the most accurate mobile dataset for UK/DACH/Nordics, and they're GDPR-serious (notified DNC lists). The catch is real: Flex plans start around $1,500/mo with no meaningful free tier, so this is a "we've found product-market fit and calling is our motion" purchase, not a first tool. ([Cognism comparison](https://appendment.com/blog/cognism-vs-lusha-vs-apollo/)) **4. Lusha - cheap, fast, LinkedIn-first lookups.** The shortest path from a LinkedIn profile to a phone number, 40 free credits/mo to test quality before paying. Good as a supplement for founders doing manual prospecting; not a system of record. ([Lusha alternatives review](https://www.cognism.com/blog/lusha-alternative)) **5. People Data Labs - if you want enrichment as an API, not a UI.** This is the one to pick for enriching your own signup form or product database in code: 1.5B+ person profiles, genuinely good docs with Python/Node/Ruby/Go samples. It's expensive per lookup (~$0.28/person, so 10k records ≈ $2,800), so use it for signups and in-product enrichment rather than bulk list building. ([PDL review](https://syncgtm.com/blog/people-data-labs-review)) **Two things worth knowing:** - **Clearbit is effectively gone as a standalone product.** HubSpot absorbed it into Breeze Intelligence - no new standalone accounts, only works inside HubSpot, and there's no Salesforce or Pipedrive integration. If you're already on HubSpot it's a reasonable add-on (~$75/mo realistic entry for a small team on top of a paid Hub seat). If you're not, skip it. A lot of "top 10" listicles still rank Clearbit without mentioning this. ([Clearbit/Breeze reality](https://marketbetter.ai/blog/clearbit-review-2026/), [Clearbit pricing 2026](https://www.cleanlist.ai/blog/2026-03-19-clearbit-pricing-guide)) - **Proxycurl shut down in July 2025.** If you find a tutorial recommending it as the cheap LinkedIn enrichment API, it's stale. ([Proxycurl vs PDL](https://nubela.co/blog/proxycurl-vs-people-data-labs/)) **If you want one answer:** Apollo now, add Clay when you're doing enough volume that waterfall enrichment pays for itself, and PDL if you're enriching inside your own product. Skip ZoomInfo at your stage - the annual contracts and seat minimums don't fit a startup budget. A caveat on the sourcing: nearly every "best enrichment tools 2026" article ranks its own vendor at #1, so I weighted the head-to-head pricing and accuracy data over the rankings themselves. Match rates vary a lot by geography and job function - worth running the same 100-row test list through the free tiers of your top two before committing.
