In short

B7 Dev cut first versions from about six months to about two, with one week of design, by using AI coding agents. It also trims hosting costs, since cloud runs about $600 to $800 a month versus $100 to $150 on dedicated servers. A pick-your-discount flow beat a flat 50% off in an A/B test. Lesson: use AI to ship faster, keep infrastructure cheap early, and test offers.
