Why Benchmark made a rare crypto bet on fomo, with $17M Series A No way out to a bank account
Before partnering with Spritz, fomo users had no way to withdraw to bank accounts. Frustration grew among newcomers who deposited for the first time but couldn't access their funds easily.
“We did not have any good mechanism for users to withdraw via bank account. This led to a lot of user frustration, especially new users who deposit on the platform for the first time.” Paul Erlanger, Co-founder, fomo
fomo needed to move fast. Building fiat rails internally would have slowed their roadmap and added operational complexity far outside their core product focus.
A fully managed fiat layer, under fomo's brand
fomo integrated Rails — a fully managed, white-labeled fiat layer that handles compliance, KYC, and support. The SDK gave their developers full UI control while offloading the hard parts of money movement to Spritz.
Integration took just two weeks from first line of code to go-live.
“The Spritz team were professional, knowledgeable, and willing to work with us to create a custom native solution.” Paul Erlanger, Co-founder, fomo
Adopted immediately. Translated into user growth.
fomo's community adopted the new feature immediately - the rails became a part of essential infrastructure.
“Before integrating Spritz, we only had the option of withdrawing to another wallet address. The impact for users who are not crypto-native is night and day.” Paul Erlanger, Co-founder, fomo
Deeper rails, wider reach
Next, fomo plans to expand its integration with Spritz to include debit deposits, push-to-debit capabilities, and broader geographic coverage.
“Spritz is crucial for fomo to unlock a whole new user base of millions of users and to bring all onchain assets within their reach.”Paul ErlangerCo-founder, fomo
