## The answer, as recorded

> Here's what I'd actually recommend, roughly in the order I'd try them:
> 
> **1. Apollo.io - start here if you're early and budget-constrained.** It's the best default because it's three tools in one: a 240M+ contact database, enrichment, and outreach sequences/dialer. Free plan gives ~100 credits/month, Basic is $49/user/mo annually. For a startup that doesn't yet know its ICP, having prospecting and sending in one place beats stitching things together. Data quality is "good enough," not great - expect to verify emails before sending.
> 
> **2. Clay - the right answer once enrichment is a real motion.** Instead of one data source, it runs *waterfall* enrichment across 150+ providers (tries Findymail, then Prospeo, then Apollo, etc. until it gets a hit), which pushes valid-email rates from ~60-70% up to ~90%. Spreadsheet-like interface, plus AI research agents for things no database has ("did they just hire a VP of Sales?"). Free tier exists; Launch is $185/mo, Growth $495/mo - and note the platform fee is separate from what you pay underlying providers, so real cost runs higher. Worth it from ~4 seats or when you're enriching thousands of records with custom logic.

> **3. Hunter.io - if yo
