Rezonant
Turn product vision into engineering-ready work for AI coding agents
Visit website →About
Rezonant is a product-management workspace built for teams shipping with AI coding agents. It maps your codebase, reads your existing tickets, and lets product managers talk through a feature idea in natural language; it then turns that into structured specs and engineering-ready tasks grounded in the actual repo.
The Chrome extension Rezonant Alter pulls live context from GitHub, Notion, Figma, and Granola while you talk, so the resulting spec already references the right files, components, and decisions. Output flows into Jira, Linear, or directly to coding agents like Cursor and Claude Code.
Built by former Stripe UK CTO Emma Burrows, backed by General Catalyst and Firstminute Capital. Used inside Skyscanner, Microsoft, and The Telegraph during private beta.

Why we picked it
We included Rezonant for bridging a gap most PM tools ignore: it maps your actual codebase and existing tickets before turning a natural-language feature idea into specs an AI coding agent can execute against, not generic user stories.
