A reflection tool
Treating assumptions as facts
Plans move forward as if key beliefs are already true, without evidence where it matters most.
Falling in Love with the Solution Instead of the Problem
Energy and excitement concentrate on what to build before the problem is fully understood.
Not Choosing Who You’re Building for First
Multiple valid users pull the product in different directions before any one is deeply served.
Using an MVP as a Product, Not a Test
Early builds are treated as versions to ship rather than experiments to learn from.
Skipping Spikes and Hoping It Works
Technical, operational, or vendor risks are trusted to resolve themselves instead of being tested early.
Building Without a Shared Reality
Teams move quickly while holding different interpretations of goals, priorities, and success.
Continuing to Build on a Broken Assumption
Signals suggest something isn’t working, but momentum keeps the plan moving forward.
Hiring Before Clarity
People are added to compensate for uncertainty rather than to execute against a clear direction.
Expanding Before Product–Market Fit
Scope, reach, or spend grows before it’s clear what’s actually working and for whom.
. No Clear Definition of “Done” or “Success”
Work continues without a shared understanding of what outcome would make it complete—for now.
How to use this
You can probably see why we didn’t try to cover all ten of these in one sitting.
Each one deserves time.
This isn’t something to work through or finish.
It’s a lens to help you notice patterns as they show up.
Start with two or three that feel most relevant right now.
You can come back to the rest when you’re ready.
Start here
If you’re not sure where to begin, don’t overthink it.
Take a moment with these questions:
Which mistakes felt familiar when we talked through them?
Which ones feel harder to reason about right now?
Which mistake would be most expensive if it were happening quietly?
You don’t need perfect answers. You’re just noticing where your attention wants to go.
Most people start with two or three mistakes. That’s enough to begin.

Ongoing Support
This is how most founders end up working with us.
If you’re making a lot of decisions at once—or you can feel that today’s choices are going to affect things a few months from now—ongoing advisory gives you someone to think with as things unfold. We work together regularly, pressure-test decisions, and adjust as your situation changes.
Some teams prefer a monthly setup. Others like having a pack of sessions they can use when they need them. Either way, it’s meant to be flexible and grounded in what you’re actually dealing with.

JumpStart (Application-Based)
JumpStart is for teams who want a starting point, but aren’t ready for ongoing work yet.
Each quarter, we work with a small number of startups through a Growth Assessment and a short follow-up session. The goal is to help you get oriented—what matters most right now, what doesn’t, and what would be worth focusing on next.
JumpStart is limited and application-based.
