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 without committing to cash they can’t safely afford.

Equity or outcome-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

What We Built

Capstacker is the infrastructure layer that makes alternative compensation actually work.

  1. Benchmarked terms

    Learn from how others structure compensation at similar stages.

  2. Automated legal setup

    Standardized contracts so deals close in days, not weeks.

  3. Milestone tracking

    A shared source of truth that both sides can see and verify.

  4. Integrated cash payouts

    Manage cash payments in-platform, with equity terms clearly documented.

Our Story

We've lived this problem from every angle. As founders, we've watched talent walk away. As operators, we've missed opportunities.

Capstacker is the platform we wished existed—one place where equity and outcome-based deals are structured fairly.

Transparency

Plain-language terms that both sides can understand and agree on.

Signal over noise

Less marketplace noise, more context to assess fit and credibility.

Partnership

We win only when our users win.

Speed

6 weeks of legal work reduced to 6 days.

What Makes Us Different

Not Payroll

Deel and Rippling handle standard cash payments.

Not Cap Tables

Carta manages the ledger; we manage the deal flow.

Not a Marketplace

Upwork handles tasks; we handle high-value partnerships.
