The problem

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

What people say

Trusted by founders and operators

We hired a fractional VP of Sales through Capstacker with a hybrid deal. The platform made it easy to structure fair compensation and track milestones. Three months in, we've closed $200K in deals and our sales process is rock-solid.

Sarah Chen
CEO • HealthTech Startup (Seed Stage)

Capstacker gave me confidence to take equity-only deals with early-stage startups. The vetting process ensured I worked with serious founders, and the equity documentation was clear and fair. I now have meaningful ownership in 3 promising companies.

M
Michael Torres
Fractional CTO • 15+ Years Experience

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.

Jessica Park
Co-founder • SaaS Startup (Pre-seed)

The benchmarks for equity compensation were incredibly helpful. I knew exactly what to ask for and why. No more guesswork or feeling like I'm leaving money on the table. The dealroom made negotiations transparent and professional.
