Foundation, a startup known for its Bitcoin wallet software, has raised $6.4 million and is shifting its focus toward AI agent authorization. The move, announced this week, signals a broader push to apply wallet-style permission controls to the growing field of autonomous AI agents that act on behalf of users.
The $6.4 million round
The funding brings Foundation’s total raised to an undisclosed figure. The company didn’t name the investors or the valuation, but the round closed this month. Foundation plans to use the capital to expand its engineering team and build out a new product line centered on authorization for AI agents — software that can independently execute tasks like trading, payments, or data access.
From wallets to AI agents
Foundation originally built its business around self-custodial Bitcoin wallets, emphasizing user-controlled private keys. The new direction keeps that principle but applies it to a different problem: giving users granular control over what an AI agent can and can’t do. Instead of a wallet holding coins, the system holds permissions — a set of rules that define an agent’s authority.
“We’re applying the same mental model,” the company said in its announcement. “A Bitcoin wallet gives you control over your money. We want to give you that same level of control over AI agents that act for you.”
Why permissions matter now
The timing reflects a broader industry concern. As AI agents become more common — handling transactions, managing accounts, even making legal filings — the risk of an agent overstepping its bounds grows. A poorly permissioned agent could drain a bank account, leak sensitive data, or execute unauthorized trades. Foundation’s pitch is that existing systems, often bolted on after the fact, aren’t built for the autonomy these agents need.
The company argues that digital finance needs a dedicated permission layer — one designed from the ground up for agent-to-human trust. That’s a different problem from standard API keys or OAuth tokens, which assume a human is watching. Foundation wants to give agents just enough rope, but no more.
What’s next
Foundation hasn’t released a timeline for the AI authorization product. The company said it’s hiring engineers with backgrounds in both cryptography and distributed systems. The $6.4 million should buy them at least a year of runway, given today’s burn rates. Whether the pivot catches on depends on how fast AI agents actually enter mainstream finance — and whether users trust them enough to hand over the keys.
