What you get back

Verdict first, in seconds. Then the full report — wedge, competitors, monetisation, the build brief. Here's a real one:

Verdict

Crowded.

The LinkedIn-signal-to-personalised-email space is contested by well-funded players already doing this well. The wedge of "recent posts" is a feature competitors ship in a quarter, not a product. To survive, this needs a sharper differentiator than the signal source.

The problem

Most SaaS ideas die because nobody pressure-tests them.

ChatGPT will cheerlead any idea you pitch it. Twitter will tell you it's brilliant. Your friends will say "go for it." None of that survives contact with the market.

You shipped to crickets

You built for six weeks. Nobody wanted it. The idea was crowded — you just couldn't see it from inside the wave.

You can't tell crowded from saturated

Three competitors look like a dead market. Three competitors with no inbound reviews look like a wide-open lane. Most founders can't tell which is which.

Your wedge is too wide

"B2B SaaS teams" isn't an ICP. You need the 200-person sliver that will pay on a Tuesday — and you need to know where they hang out.

A real, anonymised report. The full version on your idea includes every section below in depth, plus the complete phased build plan.

Verdict

Crowded.

Well-funded incumbents like Lavender, Clay and Apollo already do signal-driven personalisation. The "recent LinkedIn posts" angle is a feature they'll ship within a quarter. Survivable only with a vertical-specific messaging framework or a distribution advantage you haven't named yet.

Tech complexity

6/10

The wedge

SDR managers at 50–200-person B2B SaaS companies on Salesforce + Outreach, frustrated that reps spend 20+ minutes per prospect on manual research.

Where they hang out

  • Pavilion Slack — SDR & RevOps channels
  • r/sales and r/salestechniques
  • Sales Hacker / GTMnow community

How it works

Three steps. No spreadsheets.

  1. 01

    Describe your idea

    Paste two to five sentences. Optional ICP hint and budget context. No deck, no spreadsheet — just the thing you'd tell a friend at dinner.

  2. 02

    Watch the report stream in

    The verdict appears in seconds. Then the wedge, competitor map, monetisation models, tech complexity score, and the build brief — section by section, live.

  3. 03

    Export and build

    Download the PDF. Copy the build brief straight into your AI coding tool. Ship an MVP in a weekend instead of spending the weekend on a research doc.

"I'd spent a week convinced my idea was a wide-open lane. The validator came back 'Crowded' in ninety seconds — with four competitors I'd somehow missed and the exact reason my wedge was too soft. Saved me a month. Annoyed me for an afternoon. Easily worth £19."

Inside every report

Seven sections. Zero fluff.

Each one is structured, specific, and built to be acted on — not admired.

Verdict

Strong, Worth exploring, Crowded, or Skip — with the one factor that decided it.

The wedge

A beachhead ICP narrow enough to write the LinkedIn search query for, plus where they actually gather.

Competitor map

Three to five real players, ordered by threat, each with the specific gap you could exploit — or the honest "no gap here".

Monetisation models

Two or three pricing structures with concrete ranges and why each fits this buyer's behaviour.

Tech complexity score

A 1–10 build-difficulty rating with the two or three hardest specific challenges named — not hand-waved.

Build brief

Data model, key features, integrations, recommended stack, and a phased plan — formatted to paste into your AI coding tool as the first prompt.

Pitch refinement

The one-line version of the idea, tightened — the way you'd say it to an investor who's heard a hundred AI tools this week.

The honest answers

Three things you're probably wondering.

"Isn't this just ChatGPT in a wrapper?"

The structure is the value. Anyone can ask ChatGPT "is my idea good?" and get cheerful nonsense. The validator forces a real wedge, a competitor map with explicit gaps, three monetisation models with prices, and a build brief you can paste into your AI coding tool without editing. That structure is what makes it useful at 2am.

"How accurate are the competitor lookups?"

Treat them as a strong starting point. Most will be real and well-positioned; a minority may get a name or detail wrong. Always verify the top two before you commit to a positioning decision. The wedge and monetisation sections are where the deepest value sits.

"Why £19 and not free — or £99?"

Free attracts noise and produces lazy output. £99 is a course, not a gut-check. £19 is the price of "find out before you commit a month" — cheap enough to run on three ideas, expensive enough that you'll actually read the report.

Pricing

One payment. Three reports.

A week of your own research costs more than this in time alone. It pays for itself the first time a report stops you building something nobody wants.
