Manthan Patel (Lead Gen Man) cut his agency team from 18 people to 2. Now, he says, AI writes 100% of his code.

He builds his apps alone, mostly on weekends, with Claude Code. PenAnywhere, a Mac app for drawing on any screen, was 90% done in one weekend and went onto the Mac App Store without a rejection. TiltIt, a web app that turns screen recordings into 3D product videos, was his first build and took about a month.

In this episode: the whole path from idea to paying users. How he picks a harness, why he writes a PRD instead of hunting for prompt hacks, the production stack he runs, the security holes he sees in vibe-coded apps, a bug loop that fixes itself, and what the apps cost and earn. Then the business side: content without an editor, which platform pays, and when an AI agent is the wrong tool.

What we cover:

- 18 people to 2, and going from full-time coder to writing no code by hand

- The Apple compliance.md file he makes with Claude Code deep research

- The MVP rule: in his app, most users use 3 of 20 features

- Claude Code as a harness, and why he prefers CLIs to MCP

- Prompt hacks vs a real PRD, one feature at a time, then end-to-end tests

- The stack: Next.js, TypeScript, GitHub Actions, Supabase, Stripe, Vercel, PostHog, Sentry

- Security holes: exposed user lists, keys in the front end, bot traffic

- Sentry to Slack to Claude Code to GitHub to Vercel: fixes for the errors Sentry catches, live in under five minutes

- A 24/7 Claude agent on a VPS, a health page that checks every minute, and a blog-writing agent

- A lifetime deal for the first 10,000 users, then a subscription

- The numbers: a $200 Claude plan, about $300 to $350 a month to run TiltIt, 3 to 4 paying users to cover it, TiltIt at around $1.5K to $2K MRR, and Apple's 30% cut on PenAnywhere

- Content without an editor, why his brand deals come from LinkedIn and TikTok, and why 90% of his leads come from YouTube

- AI agents vs automations, and Claude Code's /loop
