In 2026, an MVP is no longer “the smallest thing you can build.”
It’s the fastest way to prove one core assumption with real paying (or highly engaged) users — while keeping burn under control.
Investors now expect traction metrics on day one of the raise. A beautiful vibe-coded demo that collapses under 500 users won’t cut it anymore.
90% of what feels “obviously needed” isn’t.
Use these free tools before you commit:
Discover if your idea actually has defensibility before building.
Open Tool →Find the one thing that must never change — your unfair advantage.
Open Tool →Scope creep is the #1 killer of funded MVPs.
Use this exact tool with every client — it saves months:
Draw the hard line between “must have” and “nice to have.”
Open Scoping Tool Now →My exact recommendations for funded teams (updated February 2026):
| Use Case | Recommended Stack | Cost at 10K MAU | Time to MVP |
|---|---|---|---|
| Social / Consumer mobile | SwiftUI + Kotlin + Firebase | $180–$450/mo | 10–14 weeks |
| B2B dashboard + mobile | React Native + Supabase | $80–$250/mo | 8–12 weeks |
| Heavy data / AI backend | Next.js + AWS Amplify + RDS | $400–$1200/mo | 12–20 weeks |

Key rules I enforce on every project:
Use my live calculator (clients pay me $5K+ for this analysis — you get it free):
Metrics dashboard template I give every client included in the free scoping call.
Hint: They open the data room before they open the pitch deck now.
Book a free 30-minute scoping call. I’ll review your idea, run the numbers through my tools live, and tell you exactly what it will cost and how long it will actually take.
