Deal closed!

$4,500/month retainer • 0.2% equity • 1-year vest 3-month cliff

Hiring is broken for early-stage startups

Senior operators cost $180K+. Agencies want $20K upfront. Legal help bills $400/hour. You need all of them. You can't afford any of them.

  • Market-rate compensation Burn 3-6 months of runway per senior hire
  • Everyone wants cash upfront Equity could work, but operators don't trust startups they don't know
  • No infrastructure for flexible deals Every deal is custom, slow, and full of legal gaps
  • Misaligned incentives Tracking milestones and managing payouts can be a nightmare

STARTUPS

Pre-Seed to Series A

You're moving fast but watching every dollar. You need operators who can actually execute, but paying $10K-$20K/month upfront isn't an option.

Use cases
Hire a fractional CMO for equity + success fees
Work with an agency on performance-based terms
Bring on finance/legal help with deferred payments

Trusted by founders and operators

Paying in milestones instead of upfront cash saved our runway when we needed it most. The difference between us and other founders who couldn't make these deals work? Trust, the one thing everyone talks about but nobody can actually build into a contract.

I was recently discussing collaboration with a founder who was offering equity, but without a platform set up to manage it or templates in place to move it forward effectively it didn't feel real.

We couldn't afford a full-time growth marketer at $120K+, but Capstacker helped us structure a revenue-share deal. Our marketer is fully aligned with our success, and we've grown from $10K to $50K MRR in 4 months.
