What I learned shipping a B2B email finder as a solo founder

Short summary

Solo founder shares 7 lessons from shipping findmemail.io, a B2B email finder with plain-English search instead of filter dropdowns. Concrete wins: natural language UI boosted early activation 3x; lifetime pricing ($200 one-time) captured SMBs that competitors ignore; email verification waterfall cut bounces from 12% to 4%. Public landing pages, paying users, and narrow TAM focus beat database size chasing.
