The problem
A solo founder needed a niche invoicing tool for freelance designers but couldn't justify the 4–6 month timeline of building from scratch.
What they built with GenMB
Generated a full-stack app with GenMB in two prompts. Wired Stripe Subscriptions for the Pro plan. Connected a daily MRR digest workflow.
