## The answer, as recorded

Asked on 2026-09-26 through Claude (Anthropic) with web search (model claude-opus-5).

> 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
