CrossBook

I was working as a PM and kept running into the same problem — every week I'd get flooded with feature requests from JIRA, Zendesk, Slack, and Gong. Half were noise. Some genuinely impacted ARR. And I had no systematic way to tell the difference.

I'd spend hours pulling signals from 5-6 tools, dumping them in a spreadsheet, and making a gut call. Then I'd walk into a leadership meeting and get asked "why this and not that?" — with no real answer.

So I built Crossbook — Cursor for Product Managers.

It auto-ingests signals from your stack, runs them through a deterministic decision engine, and tells you exactly what to build, what NOT to build, and what's noise. Every recommendation traces back to real tickets. Same signals in, same decision out. No hallucinations, no vibes.

The part PMs care about most: it doesn't just prioritize — it explicitly rejects bad ideas and tells you which strategy rule they violate. So when a stakeholder pushes for something that doesn't matter, you have a defensible answer.

Built the MVP in 5 days. Free to use.
