About
We're rebuilding product management around judgment.
Euler turns the scattered voice of your customers into cited, buildable PRDs, and tracks whether what you shipped actually worked. What's left for you is the decision.
The hard part was never the code.
Coding agents can build almost anything now. What stays hard is deciding what to build, and proving afterwards that it mattered.
The grunt work of product management (triaging feedback, hunting for patterns, drafting PRDs from a blank page) is exactly the kind of work agents are good at. The judgment is not.
So we built Euler to do the grunt work, cited to the source, and hand back the part only a person should own: the call.
From customer signal to shipped, and measured.
Euler pulls feedback in from uploads and the tools your team already uses, and clusters it into ranked themes. It drafts PRDs grounded in that evidence, with every claim cited, lays them on a dependency roadmap, and checks whether what you shipped moved the problem it was meant to fix.
All of it runs under a three-layer decision model: deterministic guardrails, then AI evaluation, then you. The agent proposes. You commit.
How we build it.
Four rules the product holds itself to. Each is enforced in code, not just written down here.
- Cite it or don't say it
- Answers, problem statements and PRD claims link to the customer signal behind them. When Composer objects to a request, an objection without cited evidence is rejected before you ever see it.
- Say “not yet” out loud
- A launch without enough data is labelled Insufficient data, not rounded up to a win. A plan with no matching signals says it has an evidence gap.
- Nothing acts on its own by default
- Autonomous actions ship switched off. Roadmap edits arrive as drafts, Composer waits for you to approve its plan, and overrides are recorded as decisions you can find later.
- Tested like infrastructure
- The rules that keep the agents honest are pinned by hundreds of deterministic test cases that run without calling a model, so a prompt change can't quietly loosen them.
Where we are today.
Euler is in private development. We're not SOC 2 certified yet, and the Security page says exactly what is and isn't in place.
We write about what we're learning on the blog. If you want early access, the waitlist is the way in.
Stop drowning in feedback. Start shipping the right thing.
We're putting the agents through their paces. When early access opens, the waitlist hears first.
