Howweworkwithfounders.
Three engagement models. One common goal — building companies that endure. Pick the depth that fits where you are today.
Whichmodelfitswhereyouare?
The right engagement depends on your stage and how much you want to own yourself. Start where you are — you can always go deeper as the company grows.
VentureBuilding—weco-buildfromdayone.
This is our deepest engagement. We come in as institutional co-founders — taking operating roles across product, fundraising, and go-to-market, and holding vesting equity in the company. We stay until the company stands on its own.

Vesting equity, structured against milestones — we earn as we deliver, not upfront. Plus a consulting fee that reflects the operating bandwidth we commit.
FractionalLeadership—senioroperators,ondemand.
You don't need a full-time CFO yet. You don't need a permanent Head of Product. But you need the bench. We plug experienced operators into your team on an as-needed basis — saving you up to 80% on overhead, recruiter fees, and turnover risk.
