Who hires from us

Built for people who can fund progress, but cannot manufacture time.

You have ambition, budget, and no time for the cofounder search.

You can fund momentum, but DMs, intros, coffee chats, and equity ambiguity keep turning into an unpaid second job.

You know the market, but need software or AI leverage now.

You have domain insight, customers, distribution, or a real business. You need a founder-operator who can translate that advantage into something buildable.

You would rather hire momentum than wait for luck.

Instead of networking your way toward maybe finding the right partner, start with a vetted operator who has already done 0-to-1 work.

How we vet

Vetted for founder judgment, not just availability.

The first venture stage needs someone who can work through ambiguity, make tradeoffs, and still produce concrete momentum.

Freelancer marketplace

Too task-level

Good for scoped execution, weaker when the work requires founder judgment, ambiguity, and strategic tradeoffs.

Traditional cofounder search

Too slow to start

Intros, coffee chats, chemistry calls, and awkward equity conversations can take months before anything ships.

Same Day Cofounder

Founder-grade help on demand

Hire a vetted founder-operator, start with a paid working trial, and retain only when the work creates momentum.
