What Syntropy does
Syntropy is an autonomous coding agent built for complex long-horizon tasks, that turns a feature description into a fully tested implementation. Instead of babysitting a terminal for hours writing prompts and managing context, just describe what you want, go out for lunch, and come back to a production-ready PR. Syntropy joins your Slack to send you updates, and also supports custom MCP integrations.

Company
Syntropy
The agentic coding app for complex tasks.
We are building an autonomous coding agent that takes feature descriptions and produces fully tested code implementations. Instead of manually writing code or managing prompts for hours, you describe the task once and the system writes, tests, and pushes production-ready pull requests automatically. It integrates with Slack for updates and supports custom messaging and collaboration platform integrations to fit developer workflows.
We both live in San Francisco, CA, and plan to keep the company based here after YC.
San Francisco is where we live and work. It's also a startup hub with close access to early users and developer communities we target, which helps us iterate faster and refine Syntropy for real engineering teams.
