The everyday early-stage startup crew used to comprise a pair of founders and a handful of software program engineers. Now that founding crew is simply as more likely to embody AI brokers as it’s human workers—and the businesses that serve startups are racing to adapt.
For Mercury, a well-liked Silicon Valley banking resolution, that shift in crew composition has prompted the event of a brand new function: AI agent playing cards, or digital bank cards that companies can use to delegate and automate buying choices. The playing cards launch at the moment as a part of a broader growth of Mercury’s spend administration instruments.
“Folks have already been manually issuing our digital playing cards [to agents],” says Mercury’s cofounder and CEO, Immad Akhund, who intently tracks buyer conduct. Now, Mercury will allow that course of with higher controls, together with the power to audit spending by brokers. “You’ll be able to have a whole lot of management whereas having brokers with some means to spend,” he says.
Mercury has been a founder favourite since its launch in 2019. Akhund, who spent a 12 months as a part-time companion on the famed startup incubator Y Combinator (YC) in 2017, designed the corporate as a banking resolution for software-centric entrepreneurs like himself. Mercury first made inroads with YC founders, who valued its branchless onboarding course of, then captured billions of {dollars} extra in deposits within the wake of Silicon Valley Financial institution’s 2023 unraveling. Throughout that financial institution run—the second-largest financial institution failure in U.S. historical past—Mercury acted rapidly to rework itself right into a secure haven. Inside a matter of days, due to strikes like elevated FDIC insurance coverage protection, Mercury had netted $2 billion in deposits and eight,700 new clients.
The corporate, which has been worthwhile on a GAAP foundation for the previous 4 years and generates greater than $650 million in annualized income, says that it now serves one in three U.S. startups. Much more telling, Mercury says it onboarded greater than twice as many AI startup clients in 2025 because it did the 12 months prior.
Along with AI agent playing cards, Mercury is launching a number of different new options in an expanded spend administration providing. It’s a part of the corporate’s effort to serve its banking clients as their companies develop and grow to be extra complicated—and to maintain them from adopting the companies of rival fintech options, together with Ramp and Brex.
Mercury’s new spend administration options embody budgets, automated accounting, coverage enforcement, and integration with Command, Mercury’s AI assistant. This extra full-fledged spend resolution ought to assist it higher stand towards fellow upstarts Ramp, final valued at $44 billion in June, and Brex, which was acquired by Capital One for $5.15 billion earlier this 12 months. Each corporations are recognized for his or her sturdy spend controls, which enchantment to corporations with complicated hierarchies or world operations.
On the time of their foundings, Mercury was targeted on disrupting conventional banks and Ramp and Brex had been targeted on conventional spend platforms like SAP Concur. However as every provides new capabilities, they’re doubtlessly concentrating on the identical buyer.
Digital playing cards for AI brokers
Throughout fintech, broader efforts are underway to construct cost rails for robots transacting with robots. The web, adept at transferring data, has by no means had a devoted protocol for transferring cash. Agentic funds current a possibility to lastly deal with that want whereas on the similar time supporting new types of commerce, like shopping for live performance tickets through chatbot the second seats grow to be out there. Pure, an infrastructure-focused startup that counts Akhund as an angel investor, raised $30 million in Sequence A funding final month to assist energy agentic commerce.
However in the intervening time, digital playing cards are an environment friendly option to join brokers to the present funds system, forming a bridge between outdated and new.
“I’m a extremely massive fan of playing cards,” says Akhund. “Everybody already helps playing cards. They have already got fraud safety and disputes and charge-backs and issues like that in-built. For extra day-to-day, sub-$2,000 purchases, I believe like agentic playing cards would be the method most brokers do funds.”
Ramp has additionally dipped its toe in agentic funds; its accounts payable brokers, for instance, search for card-eligible distributors and pay them routinely. There are additionally new choices for customers. In Could, Robinhood introduced that its Robinhood Gold cardholders would have the ability to direct brokers to shop on their behalf.
Adoption of all these instruments stays restricted. However ultralean startup groups are taking Silicon Valley by storm, validating the 2024 prediction by OpenAI’s CEO, Sam Altman, {that a} one-person startup price $1 billion, a situation “unimaginable with out AI,” would quickly come to go.
Mercury has diversified its buyer base over the previous 12 months, including extra conventional small companies as a complement to its expertise roots. However its model is most intently related to startups on the bleeding edge. Transaction quantity on digital playing cards for brokers could also be small for now, however providing the playing cards positions Mercury because the financial institution of the long run.
Changing into a nationwide financial institution
Mercury can also be within the strategy of acquiring a nationwide financial institution constitution from the Workplace of the Comptroller of the Foreign money. The corporate utilized for the license final 12 months, and acquired conditional approval in April.
Within the early days of fintech, startups teamed up with conventional banks to be able to keep away from the regulatory trouble of a constitution. Then, three years in the past, hundreds of thousands of {dollars} in buyer deposits went lacking in a spectacular collapse involving Synapse and Evolve Financial institution & Belief—a debacle that entangled Mercury, which on the time was Synapse’s largest client.
For Mercury, it was time to remove intermediary threat and benefit from a constitution’s structural advantages, together with higher margins and direct entry to Federal Reserve cost rails.
“A part of getting the financial institution constitution is that individuals will see us as this trusted financial institution moderately than as a fintech that works with banks and has a whole lot of disclaimers on the web site about it,” Akhund says.
Additionally in April, Mercury acquired Central, an AI-native payroll and advantages platform. Akhund envisions a future wherein AI instruments assist to orchestrate and automate interconnected workflows that benefit from Mercury’s full product suite. “You possibly can think about saying, hey, I simply employed this individual, set them up with payroll, arrange a company card for them, arrange reimbursement,” he says. “These AI options that we’re constructing work rather well if you’re orchestrating a number of merchandise beneath the hood.”
It’s the ability of compounding in motion, with an AI-era spin.
