We're building the payment rails for startup compensation

The best operators shouldn't be locked out because startups can't pay cash upfront. The best startups shouldn't wait months to hire because traditional pay structures don't work.

The Problem We're Solving

Early-stage startups need world-class operators, but cash is the one thing they don't have.

Equity or milestone-based deals could extend runway by 6-12 months. But almost nobody closes these deals because of trust and complexity.

Why deals fail today:

  • ✕ Nobody knows what's fair
  • ✕ Operators don't trust unknown startups
  • ✕ Tracking is operational hell
  • ✕ Legally risky and custom setups

Transparency

Clear terms. Fair valuations. No surprises.

Quality

Rigorous vetting for participants you can trust.

Partnership

We win only when our users win.

Speed

6 weeks of legal work reduced to 6 days.

What Makes Us Different
