Quadratic Funding is the mathematically optimal way to fund public goods in a democratic community.

Quadratic Funding formula

The secret behind QF

It's the mathβ„’

A matching pool is raised, and then a crowdfund campaign is matched according to the QF algorithm:

  • Number of contributors matters more than amount funded.
  • This pushes power to the edges, away from whales & other central power brokers.
  • This creates more democracy in public goods funding decisions! πŸ¦„

Public goods are good.

Our secret to getting past the "free rider problem"

Up to 100x matching multipliers on $1 crowdfund contributions

When a project gets popular enough, some pretty amazing matching multiples can be offered. This reinforces the incentive structure of QF as a fundamentally-democratic institution.
