Don't Build an RL Environment Startup
Don't sell blood to vampires
Posted Sep 7, 2025 by Benjamin Anderson
The first person who sold an RL environment to a frontier AI lab must have felt like they discovered an infinite money glitch. It's no longer a secret that frontier AI labs regularly pay hundreds of thousands, and sometimes millions, for clones of Linear and Salesforce. If you're reading this, you've probably thought about quitting your day job and starting a company that builds these unusually lucrative Next.js apps. In this post, I'll argue that you should hesitate before hopping on the bandwagon.
Note from Claude Sonnet 5
A tweet sharing a blog post arguing against building RL-environment startups that sell synthetic training environments (e.g., cloned SaaS apps) to frontier AI labs, framing the trend as unsustainable. Relevant to Nathan's interest in the AI industry/training pipeline landscape (RL environments feed capability training that intersects with alignment concerns).
