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.

What Axos gets

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.

Fintech meets the balance sheet

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.

Why it matters

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.
