Project details
Most founders don't fail because they can't build — they fail because they build the wrong thing.
This is a single, high-intensity session designed to give you what no amount of market research or advisor calls will: brutal clarity. Before you spend $30K on an MVP, we help you validate whether you're solving a real problem for a real customer who will actually pay.
In 2 hours, we work through your idea end-to-end — ICP definition, value proposition stress-test, PMF signal analysis, and monetization logic. You get a Go/No-go recommendation with clear reasoning, not vague feedback.
This isn't a consulting retainer or a workshop full of frameworks. It's a founder briefing — the same thinking that goes into scoping a funded MVP, applied to your idea before a single line of code is written.
If we say Go — you leave with a brief ready to move straight into MVP development. And your $500 is credited toward it

Full Stack Developer for SaaS
Vitalii did an excellent job on our SaaS MVP project from start to finish. He took the time to properly understand our requirements during the discovery phase, asked the right questions, and gave us a clear, realistic scope and estimate before development phase.
