How B7 Dev grows
4 tactics from 1 interview.
b7dev.comB7 Dev is an app development agency that has worked from South America for over a decade, keeping costs low for founders who could not afford US or European developers. Its recent growth came from AI agent development: auditing existing clients' code with Claude, building in planned stages, and passing the savings on as lower prices.

- B7 Dev has an AI agent diagnose each existing client's codebase for stability, security and bugs, then offers to fix it; some clients got about 20x performance on the same servers.B7 Dev
