What it does

It knows the whole business, not just this chat.

Every stage, every number, every decision you made and why. It does not reset when you close the tab.

  1. Business
  2. Product
  3. Technical
  4. Delivery
  5. Go to market

It covers every stage

Business, product, technical, delivery, go to market. What it learns in one it uses in the next.

It finds what breaks

It looks for what could stop you and puts the worst one first. You see it before you spend money on it.

Here is where we left off.

It remembers

Come back next week and it knows where you stopped. You never explain your startup twice.

Your team

Agents do the work. People step in when needed.

It knows when it has hit its limit, and says so instead of guessing.

Agentic C-suite

They cover every role

Agents that plan, execute and remember, so you are not carrying every function yourself.

FAQ

Everything you need to know before you start.

What is Claura?

Claura pressure-tests your startup idea, decides the smallest version worth building, and builds it. Every input carries forward, so nothing resets and nothing gets invented. You leave with a business plan, a PRD, a GTM strategy, mockups and a working prototype, all built on the same validated foundation.

Who is Claura built for?

Claura is for pre-seed to early seed-stage founders, specifically solo founders who have already started building or planning but feel uncertain their idea holds up, and need structured validation before they waste more time or money.

How does Claura pressure-test your plan?

Most AI tools tell you what you want to hear. Claura is built to find the holes. Market timing risks, competitive gaps you have not addressed, revenue model weaknesses, technical feasibility blind spots. Each one scored independently. Each one with a clear path to fix it. The goal is not validation theater. It is honest signal.

What is the Claura Startup Score?

Think of it as a FICO score for your startup idea. Every stage you complete gets scored across the dimensions that determine whether a startup succeeds: market size, problem clarity, competitive positioning, technical feasibility, and business model viability. The number tells you exactly where you are weak and what to fix. Not encouragement. A real read. The score moves as your plan improves.

Who are the experts?

Operators who have shipped in your category, vetted by us. Not a marketplace and not a directory. When you hand a stage over, we match it to someone who has built the thing you are building.

What does a handoff cost?

Two handoffs a month are included in the Expert plan. Beyond that they are priced per handoff, and you see the price before you commit.

Is my idea kept confidential?

Yes. Your idea and generated documents are private to your account by default. We do not use your idea content to train our models, share it with third parties, or surface it to other users. You control who sees your output.

How do I get started?

Sign up, paste the plan you already have, and read the score. It is free to run on your own API keys and takes about a minute.
