About Compyle
Summary
Compyle builds an AI platform for environmental due diligence firms, specifically for Phase I Environmental Site Assessments. It automates desk work that Environmental Professionals currently do by hand: collecting historical aerial photos, Sanborn fire insurance maps, city directories, and regulatory database records, then surfacing findings and drafting reports in the firm's own template. This replaces manual data ordering from vendors like EDR or ERIS and the multi-day wait that comes with it.
Go-to-market
Environmental consulting firms are the buyers; they access the platform by requesting a demo, putting Compyle on a sales-assisted onboarding path.

The coding agent that actually collaborates with you
Compyle is a less autonomous coding agent that asks before it acts. We're like Cursor or Claude Code - but you won't need to rewrite your codebase every time you use it for more than a small task. We built Compyle because we were frustrated with the direction other coding agents are headed. They're all racing to be more autonomous, running for hours without human input. This doesn't work for real production code. When agents run autonomously, they make countless small decisions that pile up in your codebase. Engineers lose ownership - they don't know what was implemented, can't effectively debug or maintain it, and struggle to build on top of it. The code becomes a black box, and they're forced to throw it away. Compyle keeps engineers in the driver's seat.
