/ who we are

We build products that compound.

Black Stone Row LLC is a one-person AI product studio. No team. No investors. Just a focused operator building a portfolio of automated, revenue-generating products.

/ how we build

The tools that run everything.

  • Flutter
  • Supabase
  • Anthropic API
  • Cursor
  • Claude Code
  • iOS
  • Framer Motion

/ the approach

No agencies. No clients. Just bets.

We don't do agencies. We don't take on client work. Every product is a bet placed on a market, built to serve that market without requiring us to be present.

The model is simple: build something useful, charge a fair price, automate what can be automated, and let time do the rest. Then do it again.

iOS first — because App Store distribution, combined with subscription revenue, creates the cleanest path to passive MRR for a solo operator. Android comes when the math makes sense.
