The answer, as recorded
For a startup, here's what I'd actually reach for, roughly in the order I'd try them: **1. Apollo.io - the default first pick.** It bundles a big database (~275M contacts), enrichment, and sequencing in one tool at ~$49/user/mo with a usable free tier. You get prospecting + enrichment + outreach without stitching a stack together. Caveat: independent tests put its email accuracy around 73%, so verify before you blast anything. **2. Clay - once you have a repeatable motion and want quality.** Clay's waterfall enrichment hits 100+ providers in sequence, so your match rate is far better than any single vendor. It's also where you do AI research/personalization at scale. Downside is cost and setup: ~$149/mo starter, $349-495/mo realistically, plus per-provider credits on top. Don't start here - start here when Apollo's fill rate is costing you meetings. **3. Snov.io - the cheapest credible all-in-one.** Finder + 7-tier verifier + drip campaigns + free CRM on one credit-based plan with a free tier. If you're bootstrapped and doing cold email, this is the best dollar-for-dollar option. **4. FullEnrich - best managed waterfall on a budget.** 15+ providers, ~$29/mo, and you pay only on successful enrichment. It's the poor-startup's Clay for the specific job of "find me this person's email and mobile." Good as a fallback layer behind Apollo. **5. Prospeo - cheapest per-record top-up.** ~$0.01/email. Worth knowing as a line item you plug into a waterfall rather than a platform you live in. **6. Breeze Intelligence (formerly Clearbit) - only if you're already on HubSpot.** Native enrichment and intent inside the CRM, from ~$45-50/mo for 100 credits on top of a paid HubSpot seat (realistic floor ~$75/mo). Two real gotchas: credits expire every 30 days with no rollover, and it only works inside HubSpot. Teams migrating from standalone Clearbit reported 30-60% cost increases. **7. Lusha - simple self-serve for US email-first teams.** $39/mo for 480 credits. Not differentiated, but fast to adopt and no procurement cycle. **8. Cognism - only for EMEA phone-heavy outbound.** GDPR posture and human-verified mobiles ("Diamond Data") are genuinely best-in-class, but it's $15K-40K/year with annual contracts. Almost always the wrong shape for a startup unless EMEA dials are your core motion. **9. ZoomInfo - mentioned so you can skip it.** Best breadth, enterprise pricing and contracts. Revisit post-Series B. My concrete recommendation: **Apollo free tier → Apollo paid → add FullEnrich as a waterfall fallback → graduate to Clay when personalization/match rate becomes the bottleneck.** If you're already committed to HubSpot, swap Apollo for Breeze to avoid a second system of record.
