Sanity Check

Don’t Prototype A Flawed Idea.

You are eager to start building. But before you cut metal or write code, you need a sanity check. The Audit is a 5-day stress test to ensure your idea deserves the engineering time.

Do you need an Audit or a Sprint?

The Audit is lighter and focused on readiness for prototyping.

The Audit

"Is it prototype-ready?"

  • Checks for fatal flaws
  • Identifies "Blind Spots"
  • 5 Days / 4 hours of team

    The Sprint

    "Is it development-ready?"

    • Deep Customer Validation
    • Unit Economics & IP Scan
    • 10 Days / 8 hours of team

      What We Do

      We apply the Enduring Profits Framework (Viability, Feasibility, Defensibility) at a high level to identify “Blind Spots”—risks that internal teams often overlook due to optimism bias.

      The Prototype Trap

      Prototypes give false confidence. They answer “Can we build it?” but ignore “Should we build it?”. The Audit forces you to answer the second question first.

      The Deliverables
