Greenwich, CT to Silicon Valley. Long way to go.
Before the billion-dollar valuations, before the IPO, before Lyft became the ride that America took when it didn't want to get in an Uber - there was a 22-year-old in Greenwich, Connecticut, keeping a private journal of carpooling ideas from his desk at Lehman Brothers. Not a pitch deck. A journal. Pages of handwritten notes about human mobility, filled between spreadsheet sessions at a firm that had less than two years left to live.
John Zimmer studied hospitality at Cornell. He graduated valedictorian. His first job was answering phones at a Hyatt, where he once dispatched milk and cookies to a frustrated family's room at 10 p.m. because the shower was broken and the kids were crying. That instinct - fix the experience, not just the problem - would become the entire operating philosophy of a company he hadn't yet imagined.
In 2007, a mutual friend on Facebook introduced him to Logan Green, a UC Santa Barbara grad who'd built a campus car-sharing system partly inspired by hitchhiking networks he'd seen in Zimbabwe. Green flew to New York within a week of connecting online. Within months, Zimmer had handed in his notice at Lehman. Three months later, Lehman Brothers filed for the largest bankruptcy in US history. Zimmer was in a Silicon Valley apartment that doubled as an office, co-founding a carpooling startup called Zimride.
The first launch was at Cornell. Within six months, 20% of the student body had signed up. By 2012, Zimride was running at 125 universities. But universities were small. Cities were where the opportunity was. And so they built Lyft - a peer-to-peer rideshare service in San Francisco with a distinctive marker: a giant pink fuzzy mustache mounted on the front grille of regular people's cars.
People smiled when they saw it. That was the point. Not just a product feature - a signal that this wasn't a taxi, wasn't a limo, wasn't a transaction. It was a ride with a person. Zimmer had learned at Cornell that the feeling a guest has when they walk through a door determines everything that follows. He was trying to make the door feel different.
What followed was a decade of controlled chaos. Lyft grew fast, then faster. Uber grew faster still, with a war chest and a willingness to operate at a loss that would test any competitor's resolve. In 2018, Zimmer admitted in a CNN interview that the pressure had broken through: "I was in a funk for several months. I was depressed. I didn't know what to do." It was a rare admission from a Silicon Valley executive - not processed through a PR firm, not framed as a lesson learned in retrospect. Just a direct account of what it felt like to be outgunned and scared.
Logan Green's response, as Zimmer recalled it, was simple: enjoy the journey. Focus on what you can control. Keep building. They did. In 2017, Uber's internal culture crisis became public. The contrast with Lyft's values-first operation suddenly mattered in the market in a way it hadn't before. Drivers and riders who cared about how a company treated people had a clear choice. Lyft's community of drivers reached 30% women, in an industry where the figure was typically 1%.
March 2019: Lyft went public at $72 per share, a $24 billion valuation, becoming the first major US ride-hailing company to hold an IPO. There are photos from the floor of the Nasdaq that day. Zimmer looks, for a moment, like someone who just carpooled across the country and actually arrived.
He literally had. Before Lyft launched, Zimmer and Green needed a way to move from the East Coast to San Francisco to work together. They used Zimride to do it - carpooled their way across America in the product they'd built. The full-circle logic that defines everything Zimmer has ever built.
In March 2023, Zimmer and Green simultaneously announced their departure from Lyft's executive roles. David Risher, a former Amazon executive, stepped in as CEO. Zimmer became Vice Chair of the Board. In August 2025, both co-founders formally stepped off the board entirely, converting their Class B supervoting shares to Class A - relinquishing formal control of the company they'd built from a Cornell carpool into a global ride network. It was, by any measure, a graceful exit. No drama, no shareholder revolt, no hostile board maneuver. Just a two-year handoff, done.
On the day he left the board, Zimmer announced his next move with a Willy Wonka quote: "The suspense is terrible, I hope it will last." The new venture is called Yes&. A consumer company-builder focused on health, connection, and joy. Co-founded with Ben Wolan, with Jesse McMillin and Mason Rothschild as founding partners. Zimmer's stated goal is to prove - not just claim - that business can make positive impact at scale. Yes& was named a 2025 Inc. 5000 honoree in its debut year.
The through-line is obvious once you see it. Hotel school, frog costumes on a Cornell campus, milk and cookies at the Hyatt, a pink mustache on a car grille, 11 consecutive New Year's Eve drives with passengers in the back seat. Every career move Zimmer has made has been a version of the same question: how do you design an experience that makes a stranger feel, for a moment, that they matter?
He hasn't stopped asking.
