Fun Secures $72M in Series A Funding to Expand Global Payments and Capital Markets Infrastructure

Fun just rang the bell on a $72M Series A, and suddenly payments infrastructure isn’t sitting in the background anymore, it’s stepping into the spotlight with something to prove. New York-based Fun is building rails for a world that doesn’t wait for banks to open, threading internet-native capital markets, crypto to fiat movement, and the messy middle where money either flows or gets stuck pretending it’s thinking. Alex Fine, Founder & CEO, saw that friction and decided to make it disappear at checkout, where decisions actually get made and abandoned carts go to die, turning Checkout into the product and conversion into the religion. Alongside him, Shiv Shrivastava, Chief Strategy Officer, is shaping how this machine scales, while Jeffrey Caron, CFO, keeps the numbers honest as the velocity picks up.

Multicoin Capital and SignalFire didn’t just co-lead this round for the vibes, they’ve been around enough cycles to know when infrastructure stops being plumbing and starts being leverage, and Infinity Ventures and Pharsalus Capital came along for the ride while Justin Mateen added that operator instinct you can’t fake, the kind that spots signal before the noise even clears its throat. Inside the business, that same instinct shows up in execution, with Greg Hemmer, Head of Business Development, pushing distribution where it counts, and Kurt Bugbee, Head of Data, making sure every transaction tells a story worth listening to. Money follows momentum, but this feels more like alignment than chase, like a table where everyone already read the same play before sitting down.

Fun is already moving serious volume, north of $18B annually, powering platforms like Polymarket, Aave, and Lighter, and that’s not theory, that’s live ammo moving through systems that don’t get second chances. When your pipes handle that kind of pressure, you don’t talk about potential, you talk about uptime, you talk about conversion rates like they’re batting averages, you talk about making “deposit failed” a phrase people forget existed because friction quietly got evicted from the building. That kind of consistency doesn’t happen by accident, it’s built through teams, including Gabriella Labi Tordjman, Head of People & Culture, who’s wiring the human infrastructure across the US and APAC as the company scales.

The origin story has its own flavor, with Alex Fine locking in the fun.xyz domain and leaning into the name like a contrarian with a point to prove, because payments aren’t supposed to be fun and that’s exactly why the name lands, disarming just enough while the product rewires how value moves across borders, chains, and expectations without asking for applause. This $72M isn’t about adding bells and whistles, it’s about scaling what already works, with Singapore on deck as Fun expands into Asia-Pacific because global money movement without Asia is incomplete, and the team is growing with engineers and operators who understand that speed and reliability aren’t features, they’re the whole game.

There’s a lesson here for anyone building in fintech or crypto, because the market doesn’t reward complexity, it tolerates it until someone removes it, and Fun didn’t invent payments, they’re making them disappear into the experience where the real power sits, less friction, more flow, less talking, more transacting, and somewhere in that silence between click and confirmation, the advantage becomes obvious without needing to announce itself.
