For solo founders, indie hackers, and pre-launch startup teams

Stop guessing. See if anyone actually searches for this.

You have an idea but no signal on whether a market exists. You're about to spend months building something nobody might want. You need data — not another framework — to decide whether to keep going or pivot.

1 Free report. No paywall.

7-day refund guarantee 1 report free — no card Ready in ~2 minutes

The cost of not knowing

What this decision usually costs.

  • Solo founders spend 3–6 months building ideas nobody searches for.
  • That is $10–50K in lost time and runway — gone before the first user.
  • A 2-minute report can stop that before it starts.

A clear go / pivot / kill call — backed by real search demand and break-even math.

What you walk away with

One report. Six answers.

Enter your buyer searches, price, and costs. You get back a defensible read on demand and economics — the same structure regardless of role.

01

Search demand

Combined volume, CPC, competition, and close variants across every term you enter.

02

CAC scenarios

Customer acquisition cost modeled at 0.5%, 1%, 2%, 5%, and 10% conversion.

03

Break-even math

The exact conversion rate you would need for paid acquisition to pay off.

04

Market sizing

Reachable visits, customers, revenue, and profit at your price and cost.

05

A plain recommendation

Go, pivot, watch, or kill — stated in one sentence you can act on.

06

Exportable

XLSX export and a shareable link. Password-protected sharing on Gold.

Example inputs

Keywords you might enter.

Replace these with your own market terms. These are the kind of searches a solo founders, indie hackers, and pre-launch startup teams would actually use.

Break-even conversion rate: 2.8% — the conversion rate you'd need for ads to cover your costs.

Recommendation

Yes — break-even is achievable at realistic capture and conversion rates.

Run it on your own idea.

Add your price, cost structure, and buyer searches. The report tells you whether the opportunity has enough demand and margin room — in about 2 minutes.

I had three ideas I thought were great. The report killed two in an afternoon and sharpened the third. It saved me months of building the wrong thing.

Questions

Before you run it.

My idea is totally new — nobody is searching for it yet. Will this help?

If nobody searches for the problem, that is the single most important thing to know before you build. The report also surfaces close variants and adjacent terms, so you can see whether any demand exists around the space.

I do not have a price figured out yet.

Enter your best guess. You can model several price points in one report and see how break-even shifts across a range of conversion rates — so you can read off exactly what price you would need to make paid acquisition work.

Is one free report really enough?

Yes — for validating a single direction. Most founders only upgrade to Bronze ($79) once they are comparing a few ideas side by side.

Risk reversal

If it does not help you decide, you do not pay.

If the report does not help you decide, email us within 7 days for a full refund. No forms, no friction.
