Brainstormer

For founders

Startup idea generator that argues back

A startup idea generator for founders should do more than emit business ideas: it should widen your options, pressure-test your favorites, and help you commit to one. Brainstormer is that sparring partner, at 11pm, on demand.

  • Ten directions when your head has been circling one
  • Pressure-testing: risks argued, not just applauded
  • Naming runs for products, features and the company
  • A decided next step instead of an open loop

Why

Sample brainstorm shown. Your challenges stay private.

Founding is deciding alone, repeatedly

The founder's real job description is making close calls without a room to argue with: which segment, which pivot, which feature, which name, what to cut. Cofounders sleep, advisors bill by the fortnight, and the group chat says "both good!" Brainstorming for founders is not a workshop problem; it is a sparring problem.

Brainstormer spars. State the decision the way you would to a smart friend and the wall diverges into directions you were not circling, each tagged with its angle. Put the plan you already half-believe in the context field and all six work from it, including the Skeptic, whose whole job is the risk you were avoiding. Then it converges: a shortlist, and one pick with reasons you can re-read at 2am.

The founder jobs it does weekly

Validate a direction: run the challenge "should we go upmarket" and watch the Optimist and the Skeptic argue both sides before you commit. Name things: the naming scenario generates candidates by mechanism (craft words, coined words, found language) like a idea generator pointed at brand. Pivot options: put "how would we kill this company" in as the challenge and the Skeptic does the work of a whole pre-mortem; the technique behind it is in our reverse brainstorming guide. Retention, positioning, pricing experiments: one challenge each, ten minutes each.

Cheaper than one hour of anyone

Pro is $39 per month billed yearly: less than one hour of any advisor, coach or contractor you would otherwise think out loud at. It does not know your market (nothing does but you); it makes your thinking wider and your decision faster, and your challenges stay private and untrained-on.

Run the churn scenario in the studio above, the one founders use most, then get started.

Questions

Can it generate startup ideas from scratch?

Yes: give it a space ("boring B2B workflows in logistics") and it diverges into concrete directions with mechanisms. The more real constraints you add, the sharper the wall.

Is my startup idea safe here?

Yes. Challenges are private by default, never used to train models, and deletable on request. Founders and agencies rely on that boundary daily.
