Play Pit
A Seattle product incubator.
Small ideas, taken seriously, shipped fast.
Play Pit LLC designs, builds, and operates its own portfolio of consumer software — playful products with real business fundamentals behind them.
The portfolio
Two live products, with more moving through the pit.
How the pit works
Every product moves through the Play Pit Playbook — a standardized path from idea to board review to production.
Prep
Every idea earns its way in. A full product overview, revenue model, and press release are written before a single line of code.
Board review
A three-person board scores each product against a ten-criterion gate and calls it: go, revise, or park.
Build & ship
An AI-accelerated pipeline — Figma to Claude Code to Vercel — compresses design-to-production from weeks to hours.
The founder
Matthew Greene is a UX leader with 25+ years across aerospace, fintech, enterprise, and consumer products — including Boeing, Vulcan, and LumaTax/Taxually, where he designed the Stripe integration featured at Stripe Sessions 2025. He is a patent holder and a career-long believer that craft and speed are not opposites.
Play Pit is that belief put to work: one designer, an AI-amplified build pipeline, and a governance playbook that keeps the fun honest.
