Interchecks Just Raised $50M to Solve the Problem Sports Betting Apps Hope You Never Notice

A profitable, decade-old payments company most people have never heard of just landed a Series C from the gaming industry's own venture arm.

Interchecks, a leading instant payments platform serving sportsbooks, fintechs, and financial institutions, just announced a $50 million Series C led by Bettor Capital, Commerce Ventures, Decades Holdings, and Thayer Street Partners. Total reported equity funding now sits at $66.3 million after a decade of building. EnkiAI

Here’s the number that should stop you: Interchecks has processed more than $50 billion in transactions over its 10-year history, achieved triple-digit net revenue growth year-over-year for the past seven years, and operated profitably since 2023. That’s not a typical venture story. Most companies raising Series C rounds are burning cash to chase growth. This one’s been profitable for three years and just decided to raise anyway. EnkiAI

So what does Interchecks actually do? It runs a payment infrastructure platform that connects banks, fintechs, and sportsbooks to various instant deposit and payout networks via a single API, routing real-time transactions across multiple payment rails while handling embedded compliance, fraud monitoring, and risk management. In plain English: when you deposit money into a sportsbook app or pull your winnings out, there’s a decent chance Interchecks is the invisible plumbing making that happen instantly instead of in three business days.

Alongside the raise, the company launched Account Funding Transactions, letting businesses fund accounts using debit credentials in real time, with built-in fraud protections covering account verification, duplicate card detection, and customizable velocity limits. That product now sits next to their existing Pay-by-Bank option on a single RESTful API, so clients can offer multiple deposit methods without juggling separate integrations. EnkiAIEnkiAI

I want to apply moat through compliance, a mental model I dig into in the book, because this deal is a perfect case study. Most fintech founders treat compliance as a tax they have to pay before they get to build the fun stuff. Interchecks treated it as the actual product. The company is a certified PCI Level 1 Service Provider and SOC 2 Type 2 certified, and works with major global networks including Visa and Mastercard. Those aren’t marketing badges. They’re the reason sportsbooks, banks, and regulated fintechs trust this company to touch their money flow at all. EnkiAI

I spent years at Robinhood building inside one of the most heavily regulated corners of fintech, and now I’m doing the same thing at /mkt with Reg A+ offerings running through tZERO’s infrastructure. The lesson repeats everywhere: in regulated markets, the company that wins isn’t the one with the slickest app. It’s the one that made compliance so airtight that everyone else has to build on top of them instead of around them.

Here’s the contrarian read. Bettor Capital, a growth equity firm focused entirely on the real-money online gaming market, led this round. That’s not a generalist fund dabbling in fintech. That’s the gaming industry’s own capital deciding that payment rails, not better odds or flashier apps, are the next place real value gets created in sports betting. Everyone’s watching the front end of gaming apps. The smart money just quietly bought a piece of the plumbing underneath all of them. EnkiAI
