The answer, as recorded
## What I'd actually use **1. Clay - the default answer for most startups.** It's a spreadsheet-style enrichment engine that runs "waterfalls": it tries provider A, then B, then C until it finds a verified email or firmographic field, so match rates beat any single vendor. You pay per credit account-wide (unlimited seats), which suits a 3-person GTM team. Plans run roughly free (100 credits) → ~$149-185/mo Starter/Launch → ~$349/mo Explorer. Caveat: credits burn fast and the learning curve is real - budget a week. ([Clay pricing breakdown](https://abmatic.ai/blog/clay-pricing-guide-2026), [Clay vs Apollo](https://thegtmdirectory.com/compare/clay-vs-apollo)) **2. Apollo.io - best value if you want data + sending in one tool.** ~275M contacts, built-in sequencer and dialer, a usable free tier, and paid from ~$49-59/user/mo. Data quality is mediocre compared to a waterfall (stale titles, job-change lag), but for a startup doing its first 1,000 outbound touches it's the fastest path from zero to pipeline and replaces three tools. ([Apollo vs Clay](https://lagrowthmachine.com/apollo-vs-clay/)) **3. Prospeo or Findymail - the cheap, accurate email layer.** If all you need is "name + company → verified work email," these do it at a fraction of a full platform, with bounce-rate guarantees and frequent refresh cycles. Also the right building blocks to slot into a Clay waterfall instead of paying premium-provider rates. ([Prospeo](https://prospeo.io/s/lead-data-enrichment-tools)) **4. HubSpot Breeze Intelligence (the old Clearbit) - only if you're already on HubSpot.** Clearbit was acquired in 2023 and no longer exists as a standalone product; it's now a credit-based add-on inside HubSpot. Native CRM enrichment and form-shortening are genuinely good. If you're not a HubSpot shop, skip it entirely - that's a deliberate lock-in. ([Clearbit alternatives](https://moderninbound.com/blog/best-clearbit-alternatives)) **5. Enrich Layer (formerly Proxycurl) - if you have an engineer.** A straight REST API for person/company profile data. Cheapest per-record option when you're enriching inside your own product or signup flow rather than in a GTM tool. ([tool roundup](https://gumloop.com/blog/lead-enrichment-tools)) **6. RB2B or Warmly - website visitor identification.** Different category, but the highest-ROI enrichment for an early startup with traffic: it tells you *which* companies (RB2B claims person-level for US visitors) are already on your pricing page. Enriching inbound intent beats enriching cold lists. **7. ZoomInfo - name it, then don't buy it.** Best coverage, especially for direct dials and org charts, but annual contracts commonly $15k-40k+ with seat minimums and aggressive auto-renewal. Wrong shape for a startup unless you're selling into enterprise with a funded sales team. ## Practical take For a seed-stage team: start on **Apollo's free/cheap tier** to validate your ICP and messaging, then move the data layer to **Clay** with **Prospeo/Findymail** as waterfall inputs once you know what you're enriching for and why. Add **RB2B** the moment you have meaningful traffic. Two flags on sourcing: the "best tools 2026" listicles are heavily SEO-gamed - several rank their own product first (Pubrio's roundup crowns Pubrio), so I ignored those placements and named tools on their mechanics. And all pricing above is from secondary comparison sites, not vendor pages; treat the figures as ballpark and verify on the vendor's own pricing page before you commit, since enrichment pricing changes often.
