You could ask any AI to help you test a business idea. A good model would do a reasonable job. But it would also let you skip the hard parts, soften a tough verdict when you push back, and forget everything by tomorrow.
Juno is built on a method developed over 25 years of real-world practice. Four steps, each with a checkpoint enforced by code.
Your problem statement, customer profile, market research, and interview questions all build on each other. You do the interviews. Juno structures everything else.
How Juno works
Foundations
Get clear on the problem you are solving, the specific person who has it, and the assumptions you most need to test.
Market intel
Real-time competitor and market data, pulled together into a clear picture of the opportunity and who else is in it.
Interview guide
A tailored conversation script, built from your idea and the market research, ready for you to take to real people.
Analysis and summary
A full analysis of your interview transcripts, with a clear verdict and a report you can act on.
What each stage does
Foundations
Helps you get clear on three things: the problem you think you’re solving, the specific type of person who has that problem, and the assumptions you most need to test. You’ll work through five readiness checks before moving on.
Market intel
Pulls real-time competitor and market data, then brings it together into a picture you can actually use. Who else is solving this problem, how big the opportunity is, and whether your assumptions hold up against real evidence.
Interview guide
Builds a tailored 10 to 15 question conversation script from everything you’ve worked on so far: the problem, who you’re solving it for, and what the market research uncovered. All you need to do is have the conversations.
Analysis and summary
Produces a 12-section analysis from your interview transcripts with a clear verdict: go ahead, stop, or change direction. The recommendation comes from what customers actually said, not what the AI thinks you want to hear.
Why Juno, not ChatGPT?
A proven method, not a prompt
Built on 25 years of real-world validation research.
Five readiness checks, code-enforced checkpoints, and a clear path from your first idea through to a verdict backed by evidence. You follow a process that works, not a conversation that wanders.
The right AI for each job
Different steps use different AI tools.
Claude handles the structured discussion, Perplexity pulls real-time market research, and Gemini brings it together. You get current data, not information that’s two years out of date.
Picks up where you left off
Everything you share is stored and carried forward.
Your problem statement, customer profile, market research, and interview analysis all persist across sessions. Come back tomorrow and Juno knows exactly where you are.
Trust and Privacy
Your data stays yours
Individual authentication, isolated data storage, and no training on your conversations. Everything is deleted at the end of the beta.
Quality checked
Every agent output passes through 9 automated quality checks before reaching you. Periodic AI audit sweeps catch issues humans might miss.
Checkpoints enforced by code
Progression is enforced by code, not AI. The system can’t be tricked into skipping steps. You complete each one before moving to the next.
When you’ve got signal strength from interviews, Theia takes over for Stage 2: testing demand in the real market with landing pages, ads, outreach and pilots.
