Three years ago, JPMorgan Chase executive Doug Petno was at a New York City party celebrating a colleague’s retirement when his boss, Jamie Dimon, called Petno over.

It was March 9, 2023, and the customers of a West Coast lender known for catering to startups had been withdrawing deposits in droves.

“Jamie looks at me and says, ‘Get on this call,'” Petno told CNBC this week in an exclusive interview.

On the line were regulators with an urgent question: Was JPMorgan interested in buying Silicon Valley Bank?

California’s finance regulators seized SVB the next day, completing the sudden collapse of an institution at the heart of the American startup community. Over that weekend, Dimon, Petno and other JPMorgan leaders repeatedly weighed whether they should purchase the bank, which had just lost $42 billion in deposits. They decided against it, in part because thousands of SVB clients were signing up for JPMorgan accounts, anyway, in a flight to safety.

“We had three years’ worth of incoming clients in a weekend,” said Petno, who is co-head of JPMorgan’s commercial and investment bank. “Onboarding teams were opening up accounts around the clock.”

Emboldened by what they were seeing, Petno had an idea: What if JPMorgan could build a true competitor to SVB — as well as startups Brex, Ramp and Mercury — all of whom had carved a profitable niche serving founders and venture capital investors?

“We went to our board and said, ‘there’s a vacuum in the market,'” Petno told CNBC. “At that very moment, everybody saw the opportunity.”

For JPMorgan, already a giant in Main Street and Wall Street finance, winning the more specific niche of startup banking from West Coast rivals is about more than gaining deposits. It’s both a key element of the growth strategy for a bank with more than $180 billion in revenue last year, and also a means to help the New York-based lender stay close to technology developments for itself.

JPMorgan, with a tech budget of nearly $20 billion this year, is aiming to not only serve startup clients and VC investors better, but to learn from them. The firm keeps a close eye on Silicon Valley startups for solutions to problems the bank itself faces, from cybersecurity to quantum computing.

In fact, when a JPMorgan client announces a round of artificial intelligence-related cutbacks to jobs and expenses, the firm will often send a team of bankers to investigate how the client is doing it, said Petno.

Typically, the bankers find that implementing new AI agents is only a fraction of the reason for layoffs, while other factors like over-hiring and inefficient processes account for the rest, he said.

JPMorgan began its startup banking business in 2016 as it became aware of its tech-focused rivals during its westward expansion. In the beginning, it only served bigger, more mature startups.

That’s in part because the bank didn’t yet have a digital banking solution that younger founders in particular craved, Petno said. It also didn’t have enough investment bankers at the time to target smaller, riskier startups.

For years, the view on JPMorgan from some in the VC community was that it took too long to open an account, or that resolving issues around payments involved dealing with time-consuming visits to a branch, investors told CNBC.

“They want to go to the website to open an account, and if it’s more than 15 minutes, they’re done,” says Petno.

But in the weeks that followed the SVB collapse, Petno and his team moved quickly, hiring a few key players from SVB, including then-SVB Capital President John China, who today leads JPMorgan’s innovation economy business along with Andrew Kresse.  

By late April of 2023, JPMorgan found itself looking at buying another wounded California-based bank. This time, it made the winning bid for First Republic, which also catered to the tech community.

With fresh learnings from SVB and the banking operations of First Republic, JPMorgan doubled its revenue from startup banking in 2023, according to the company.

Despite the digital banking focus, a startup founder will still sometimes walk into a Chase branch to deposit a huge funding check into a regular account. Now, when that happens, JPMorgan’s systems immediately gets that client moved to the startup team, Petno says.

Besides SVB, which is now owned by First Citizens Bank, and the startups Mercury and Ramp, competitors in the space include Stifel and Customers Bank. In January, Capital One acquired Brex for $5.15 billion.

Since most startups fail, JPMorgan identifies companies that it expects to be winning bets, seeking to develop relationships with them earlier in their life cycle, like SVB did.

That way, it can provide not only core bank accounts, but lucrative investment banking advice along the way.

JPMorgan’s ultimate vision is to become the one-stop shop for founders, serving all their needs, including international expansion, from the seed round to initial public offering and beyond.

“Once you’re onboarded, you can never outgrow JPMorgan, from unicorn all the way to a Magnificent 7,” Petno said.
