Axos buys AI fintech Arc Technologies to bolt modern software onto a bank

Axos is buying Arc Technologies, an AI-native fintech that banks tech startups, and bolting its software onto a chartered bank.

Axos Financial, a US digital bank with about $29bn in assets, has agreed to acquire Arc Technologies, the company announced . Arc runs a financial platform for technology and growth companies, bundling cash management, debt financing, and AI-powered software in one place. Neither side put a price on the deal.

Arc launched in 2021 to give startups a slicker alternative to old-school business banking. It now handles treasury, capital markets, and what it calls agentic finance: software that automates finance chores, surfaces insights, and moves money. Backers include Y Combinator, NFX, and Bain Capital Ventures.

Axos wants two things here. The first is Arc’s software and its foothold in the startup world. The second is its AI, including a CFO agent named Archie that Arc shipped last year.

The logic runs both ways. Arc wrote polished software but never held a banking licence, so it leaned on partners like Stripe to move customer money. Axos brings the charter, the deposits, and 25 years as a branchless bank. Each side owned the half the other lacked.

Axos also has a target in mind: the millions of US small businesses it says big banks underserve. Arc’s customers and software give it a quicker route to them.

That gap explains a wave of tie-ups across the sector. Modern fintechs win users with design and speed, then hit a wall the moment they need a balance sheet, a licence, or cheap deposits. Joining a bank clears it.

The deal lands as incumbents race to graft AI onto finance rather than build it slowly at home. Some buy an AI startup outright . Others watch fintechs move first, from banking built for AI agents to the wider shift toward agentic AI in enterprise finance . Money follows the same path, into embedded lending and vendor financing that lives inside the tools companies already use.

For Arc customers, nothing changes yet. The wager is that a fintech with a real bank behind it can outbuild either side alone. Whether the pairing moves faster than a nimble startup, or a big bank on its own, stays an open question. The deal should close this month, subject to the usual conditions.
