Clarno

Pressure-test your startup idea before you build it

Building an idea is easier than ever. Knowing whether you should build it is still hard. Clarno is an AI platform that puts your startup idea through a simulated market before you spend months and money building it.

How Clarno works

1. Start with the real market

• Bring an idea or a product you have already shipped.
• Clarno researches who is already struggling with the problem.
• See what solutions people use today and what they pay.
• Every sourced number is backed by evidence.
• When a number cannot be found, Clarno says not found instead of making one up.

2. Let the market argue back

• Put your idea in front of up to 50 market agents.
• Agents have their own perspectives, memory, and budgets.
• They challenge your assumptions instead of simply agreeing with you.
• They pressure-test the problem, customer, offer, positioning, and pricing.
• Their arguments happen across moderated rounds, so you can see where objections hold up.

3. Get a verdict

• Clarno evaluates the idea using decision gates, not a meaningless AI score.
• You get the verdict together with the evidence behind it.
• If the idea does not pass as pitched, you do not simply hit a dead end.
• Three alternative directions are presented, each with its strengths and weaknesses.
• You choose a direction, and the market agents pressure-test it again.
• Failed ideas also get an opportunity solution tree with ranked pivots.

Build what survives

When an idea survives the pressure-test, Clarno can take it into the build stage. Use the same market agents to shape:

• Product features
• Pricing
• Brand positioning
• Go-to-market strategy
• Business case
• MVP architecture
• Build-ready prompts for your own development tools

No lock-in. You keep building in the tools you already use.

Who is Clarno for?

• Solopreneurs who want to test an idea before investing their nights and weekends.
• Startup founders and teams who want to pressure-test their wedge, pricing, and positioning.
• Startup studios that need one consistent standard for screening ideas.
• Investors who want a market model alongside the pitch deck.
