How it worksSamplePricingGuide
Free reality check · no account

Run the tests that decide if your idea is worth building.

Start with the messy version. StackFlight sharpens the customer and problem, scans market evidence, then turns the riskiest assumptions into proof tests.

No account. No market claims. First we test whether the idea is clear enough to validate.

How it works

Idea in. Proof plan out.

01

Check the rough idea

Start here. We show whether the customer, painful moment, and measurable outcome are clear enough to test.

02

Scan the market

Save the idea, add a focused founder brief, and scan live market evidence for risks and alternatives.

03

Collect real proof

Run seven-day demand tests, attach evidence, and decide to continue, narrow, pivot, or stop.

Output

Less dashboard. More decision.

Each validation begins with one decision view: the current signal, the few risks that matter, and the next proof plan. Open the evidence and build details only when you need them.

72/100

Clear pain. Unproven willingness to pay.

Recruit five independent consultants who sent a proposal this month. Ask two to pay for a concierge version before automating the workflow.

01

Proof score

A directional snapshot of how much evidence exists and what still needs testing.

02

Priority risks

The few assumptions most likely to break demand, trust, or adoption.

03

Proof plan

Concrete demand tests with pass/fail thresholds you can run this week.

Why StackFlight

Stop building on a hunch.

Most ideas die from skipped validation, not bad code. StackFlight turns a vague idea debate into a clear verdict and a proof plan you can actually run — before you commit weeks to building.

Scope

One sharp test

StackFlight finds the shortest demand test that can prove the idea deserves real work.

Speed

Evidence

Decision trail

Every saved validation turns a vague idea debate into a readable set of risks, assumptions, and proof tests.
