SAFE & FAST are simple on paper. Complex in practice.

Templates document intention. Capstacker executes the reality.

The Performance Gap

Founders use SAFEs and FASTs for speed, but simplicity often masks future confusion. These agreements look trivial until you need them to perform.

“Simple on paper does not mean simple in practice. We grapple with how conversion really works—it’s confusing to understand how ownership math actually converts.” — Reddit Founder
“I signed a FAST with an advisor, only to realize the equity vested unclearly because the template didn’t define milestones the way I assumed.” — Startup Forum User

The Hidden Risks

  • Deferred promises become cap table surprises
  • Ambiguous terms lead to vesting disputes
  • Zero automation for milestone triggers

Paperwork alone does not align incentives or track performance.

From Contract Intent to Outcome Execution

Capstacker doesn't replace the legal function of your agreements—it operationalizes them. We turn static text into automated execution logic.

  • Preserve runway with automated equity triggers
  • Objective milestone + performance alignment
  • Built-in confidence for strategic hires
