Summary
Fun, a blockchain-based payments infrastructure startup, has announced completion of a $72 million Series A funding round, marking its emergence from stealth. The round closed in late January 2026 and was co-led by Multicoin Capital, a cryptocurrency-focused investment firm with theses on crypto payments and stablecoins, and SignalFire, a technology-focused venture capital firm. Additional investors in the round included Infinity Ventures, Pharsalus Capital, and Justin Mateen, cofounder of Tinder, signaling broad institutional confidence in the company's market opportunity.
The company operates at the intersection of traditional finance and digital assets, solving a critical infrastructure gap: enabling seamless conversion between cryptocurrency and fiat currency for end-user platforms without requiring users to navigate third-party crypto exchanges or traditional banking channels. Fun's technology powers deposit, withdrawal, and settlement flows for existing platforms including Polymarket, a prediction market platform. According to founder and CEO Alex Fine, the company addresses a fundamental question in fintech: "If you have a money app, a finance app, how do you actually get the money in and out?" Fine, 26, dropped out of Stanford University in 2020 and workshopped several startup concepts before concluding that blockchain technology would eventually supplant legacy financial databases.
The Series A funding reflects significant tailwinds in the fintech and crypto infrastructure sectors. Over the past year, major technology platforms—including Meta, Stripe, and Shopify—have announced crypto payment integrations, driven partly by a regulatory environment shift under the Trump administration. Fun anticipates this adoption will accelerate among non-crypto-native companies seeking to offer digital asset functionality to their users. The company plans to deploy the Series A capital toward engineering talent acquisition, geographic expansion into Asia-Pacific markets, and strategic acquisitions. The Series A followed a previously unannounced $3.9 million seed round closed in 2022. Fine declined to disclose the valuation at which the Series A was raised.
