Thinkr

For Startups

AI Product Management Tool for Startups and Solo PMs

At a startup, the Product Manager (or the engineering-led founder doing the role) wears every hat. Research, drafting, critique, deck for the next round, prototype for the customer call. Thinkr collapses that into one workflow without collapsing the quality.

Before & after

From wearing every hat badly to one workflow that keeps the quality.

Before Thinkr

  • Research, spec, critique, deck, and prototype each live in a different tool.
  • The one Product Manager is the bottleneck on all five at once.
  • Shortcuts at speed mean specs ship with the holes still in them.
  • Investor and customer materials get rebuilt from scratch every time.

With Thinkr

  • One workflow runs research → draft → critique → deck → prototype.
  • The structure is handled, so your time goes to the bet, not the formatting.
  • Critique holds the quality bar even when you’re moving fast.
  • The same spec becomes the deck and the clickable prototype.

One PM wearing every hat

Founder, researcher, and PM at once. Capture customer calls and competitor notes in Notebook, draft the spec with that context loaded, then generate the investor-update deck from the same source — so validating the bet and pitching it run off one workflow, not three rebuilds the night before the meeting.

Critique before the founder review

The senior reviewer at a startup is the founder, or the founder is you and the reviewer is your co-founder. Either way, Critique catches the gaps before the conversation starts. Conflicts with prior strategy. Missing success metrics. Risks the draft glossed over.

Generate the customer-facing prototype

A 2-pass HTML prototype from the spec. Click through it in the customer call instead of describing what the screens would look like. Faster validation, fewer "I do not get it" moments.

Grows past the solo stage with you

Thinkr starts as a single-Product-Manager workflow and opens into a shared workspace the moment you bring on a co-founder or your first PM hire. Same PRDs, same Brain, same critique standards — now collaborative, with role-based sharing and an activity trail.
