Fun Announces $72M Series A

Fun is announcing a $72 million Series A, co-led by Multicoin Capital and SignalFire.

Financial markets are undergoing their first real step-function change in generations. Capital is moving faster, across more borders, between more systems, and into more hands.

The existing infrastructure wasn't built for this scale, speed, or complexity. We are rebuilding it from first principles.

At a certain scale, off-the-shelf payments cost growth. Fun builds the highest-converting payment flows for the largest global applications. White-label, white-glove, engineered around how their users actually behave. We power deposits, withdrawals, and settlement for platforms where payment performance directly determines user retention.

"Polymarket runs at a scale that breaks most payments infrastructure. We've evaluated every major payments vendor, and Fun is in a different category. They operate like part of our team, building custom flows around how our users actually behave. They are meticulous about every detail and solve edge cases that others don't notice.

At our size, every percentage point of conversion is millions of dollars and millions of users — and every reliability failure becomes a public conversation. Bespoke engineering is the only way to deliver results, and it's how Fun has built the highest-converting, most reliable deposit flow we've ever run."
Josh Stevens, VP of Engineering, Polymarket

It is a privilege to serve the largest teams in fintech, and we’re humbled by the opportunity we’ve been given.

This capital enables us to expand across Asia-Pacific with a new office in Singapore, pursue acquisitions that deepen our infrastructure, and grow our team of exceptional engineers and operators.

Money is the substrate of the modern economy. Improving how it moves is one of the highest-leverage problems you can work on.

If you want to do the most meaningful work of your career, join us. We're hiring.
