You can build anything.

Lacunio checks your idea against the real market before you build it.

So can everyone.

Building isn't the problem anymore. Knowing what to build is.

You built it. You shipped it.

Then came the posts, the marketing and the money for ads.

Nobody came.

Either nobody needed it, or it drowned in the flood of everything else.

Start with what they need.

Lacunio listens to what people search for, ask about and complain about.

See who's already there.

Every competitor, what they offer and where they fall short.

Shape it to fit the gap.

Find what nobody offers yet, or what you can do better than everyone else.

Build the right thing.

Now you know it's worth your time.

And they will come.

This time, they were already looking for it.

Check an idea in minutes.

Describe it in one sentence. Lacunio looks at who is already there and who is asking for it, then tells you straight.

An app that turns voice memos into invoices for tradespeople

VerdictNot like this.

Eleven tools already turn voice memos into invoices. None of them handles materials and hours in one go.

Demand
High
People ask for it every week
Competition
Crowded
11 tools, 3 with funding
Open gap
Materials and hours
No tool bills both
A better angle

Build it for tradespeople who bill materials and hours together.

Based on 38 sources, each one linked.

Why not just ask an AI?

You can, and you should. Lacunio adds what a single answer leaves out.

Ask an AI

  • One answer, one or two sources
  • Often just a no
  • Rarely looks at who is already there
  • You are on your own afterwards

Lacunio

  • Deep research, every source linked
  • A clear yes or no, with reasons
  • Every competitor, and where they fall short
  • A community that is building too
