Persistence is a virtue
and sometimes just a cost.

Set the condition while you can still think

Before starting, or now if you did not: what would you need to see by when, and what would you do if you did not see it. Written down, before hope and sunk cost are involved.

Sunk cost is the whole problem. Everything invested makes stopping feel like waste, when the money is gone either way and the only live question is what the next month buys.

The signals that mean something

Real signal: customers who paid do not repeat or refer, acquisition cost is not falling with experience, and the thing you thought would work has been tried in three variants without moving.

Not signal: growth being slower than hoped, competitors doing well, or a bad quarter. Those are normal. The distinction is between a business improving too slowly and one not improving at all.

What the engine actually does with this question

This question routes to Startup Genius — one of 29 engagements the platform runs. It does not produce advice in general; it produces this analysis for your business:

✓ Sizes who could realistically buy this — not the size of the industry
✓ Estimates what a customer costs to acquire and what they are worth to you
✓ Tests whether the gap between those two survives contact with reality
✓ Models the cash you need and when break-even actually arrives
✓ Names the assumptions the whole idea rests on, ranked by damage if wrong
✓ Gives the cheapest test that would prove the riskiest one false

You watch the analysis get built before you pay anything. Read a complete report here if you would rather see the depth first.

Questions people ask about this

How long should I give a business before quitting?

Long enough for the sales cycle to have run several times, so that the results reflect the business rather than its newness. For most that is at least a year; the important part is setting the period in advance rather than extending it repeatedly.

Is it failure to stop?

Stopping something that is not working and redeploying the effort is a decision, not a failure. The costlier outcome is the business that neither fails nor succeeds and absorbs years.

Should I pivot instead of quitting?

If you have learned something specific that suggests a different offer or customer, yes — that is what the effort bought. If the pivot is a general hope that something else might work better, it is usually quitting with extra steps and more expense.
