## The answer, as recorded

Asked on 2026-10-10 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's what I'd actually recommend, roughly in the order I'd try them at a startup:
> 
> **1. Clay** - my default answer for most startups today. It's a spreadsheet-like workspace that runs "waterfall" enrichment: it tries one data provider, and if that provider has no email/phone, it falls through to the next, across 100+ sources. Single-source tools land around 55-65% email coverage; waterfalls typically hit 85-95% on the same list. It also does AI research (scrape a site, classify a company, write a personalized line). Pricing is credit-based and per-account rather than per-seat, so unlimited users - free tier to test, paid from ~$134-149/mo, and real usage often lands $200-500+/mo. Downside: it's a tool you have to learn, and credits get expensive if you're sloppy.

> 
> **2. Apollo.io** - best if you want one bill instead of a stack. Database (~275M contacts) + enrichment + sequences + dialer + lightweight CRM. Free plan is genuinely usable, paid from $49/user/mo annual ($59 monthly), Professional $7
