Kevin Hartz - The Early Stories Behind Billions

Eventbrite and Airbnb Rivalry
By now, the dot-com hangover had finally lifted enough for a new kind of optimism to emerge in the Valley. It was post-Web 2.0 online communities and user-generated everything—a belief that if Flickr could turn photos social, then anything could be turned social.
Kevin, immediately after leaving Xoom in 2005, carried his adventurous spirit two blocks south to a second-floor space that smelled of plywood and fresh drywall. In that shared San Francisco office which borne both wedding plans and wireframes, Kevin and his then fiance, Julia, sketched the blueprint for their “next big adventure.” They would bring in technical cofounder Renaud Visage, together building what would become Eventbrite.
It went against conventional wisdom—never start a business with your friend, let alone family. Even Kevin’s own parents’ who “have always loved each other their entire X number of years” could “never work together.” There was just a “different calculus” required for professional partnership, one that had to “kind of be tested out.”
But neither partner’s rebellious spirit would be deterred. They set up the guidepost—that if the venture ever strained their marriage, one “would step out or do something else.” And with that guardrail in place, they “kept going and going and going”—and against all odds, it “just kept working and working.”
A year passed, and it was clear the newly married Kevin and Julia complemented each other perfectly. They were both relentless, and they both understood that about each other. Day by day, the pair would match each other’s obsession—with Julia not even pausing in the delivery room, answering customer service emails until a worried nurse had to wrestle the laptop out of her hands.

Just down the street from Eventbrite, an industrial designer named Brian Chesky had just moved in. Because the Valley rent outpaced his savings, Brian began filling his space with air mattresses and subletting to short-term guests—a business that would soon turn into Airbnb.
In 2009, Kevin would take interest in the host-and-guest platform, investing during Airbnb’s Sequoia round after they came out of YC. And apart from just being two blocks away from each other, both Eventbrite and Airbnb were GMV-driven businesses with “similar formats” and “around the same net revenue,” inciting “these revenue wars” that challenged the two startups to outgrow one another.
Eventbrite would pull ahead for a moment later that year. But Airbnb had incredible network effects, and “as soon as those network effects took hold, the numbers on the Airbnb side just skyrocketed.” Eventbrite was still growing at a solid pace, but the Airbnb numbers were just “magical.” Kevin had lost the competition, feeling “depressed for about five minutes” before being “very happy” for the success of Brian and Airbnb.
But Kevin’s interest in promising ventures wasn’t limited to Airbnb. In 2010, he backed Pinterest at their seed after being introduced to Silbermann and Sciarra through Ed Baker—an “amazing growth person” from Facebook, Uber, and later Aura. Kevin had also known Uber’s founder Travis Kalanick since his Red Swoosh days, investing in Uber during their 2011 Series B.

By now, Kevin had established a legendary reputation for himself. From co-founding three highly successful companies to successfully betting on what became era-defining companies, Kevin had an undefeated intuition and an insatiable hunger to match. And with the ever growing network that followed, Kevin would institutionalize future investments into his fourth company—A*.
Investments and Sauron
In the modern venture landscape, where funds are being saturated with startups that parrot the “Peter Thiel competition is for losers” mantra but still dive into a Red Ocean, Kevin Hartz emphasizes collaboration—since “the sum is greater than the parts.”
He partnered with Godam and Bennett, more measured investors who balanced out Kevin’s “impulse to shoot from the hip.” Together, they formed A*, an early stage venture capital firm that stood out for being “a collaborative group.” And they approached partnership differently—rather than having a singular lead partner per deal, the entire A* team would work together “on all aspects of understanding the founders and [their] business.”
This collective immersion also meant more selectivity. A* was more “kind of snipers versus a bazooka,” backing ventures like Decagon’s AI customer service, WHOP’s creator tools, and Cape’s “cloaked cell phone,” which Kevin believes might be “the future of telecom infrastructure.”

But Sauron’s origins came differently. A mutual friend at Waymo introduced Kevin and Jack Abraham (from Atomic) to Vasu—a roboticist with a Zipline pedigree and PhD focused on self-driving cars. The three had seen “all this investment and work done in self-driving cars,” and wondered where else the tech could be applied.
The team would then come across a realization after an intruder broke into the Hartz house. Kevin and Julia had “two different systems installed—and neither detected this person.” It was only when the assailant tried to “push their way into the neighbor’s house,” that police came and swarmed the street. Kevin would then realize—that amid all the tech innovation of the 20s, “there’s been zero innovation” in the home security space since Ring. And so the Orindan serial entrepreneur, together with Vasu and Jack, co-founded his fifth and most recent company, Sauron.
Mentorship and Life Lessons
There was a common theme between each adventure—from wiring up hotels for Connect Group, building international money transfer networks at Xoom, or guiding early-stage startups with A*. No matter where he went, Kevin had always been drawn to “extraordinary people who [were doing] extraordinary new things.” He had learned it was “best not to be focused on a particular technology,” but instead to be “focused on people.”
Kevin’s people oriented mindset guided his investments too. When evaluating a “seed-stage company—especially first-time founders—they don’t have a rich history you can pattern match on.” So instead Kevin would ask them “about their families and their parents and their siblings—how competitive they are, how intellectually oriented they are.”
And there was a particular grit that Kevin would notice among founders who were first-generation immigrants. Traveling across borders and coming to the U.S., they had “overcome a lot of obstacles to do great things.” They had “this edge—this drive to want to win and work harder than everyone else.”
But then there were the “really extraordinary people” like Peter Thiel. He was not only “smarter than everyone at Stanford,” but also “had a different way of seeing the world”—the “added sort of X factor which makes him an N of one.”
Peter was one of many mentor figures to Kevin—with Peter’s “few words and insights” being “really impactful and incredible,” Roelof Botha serving on the board at Xoom and Eventbrite for more than a decade each, and Pierre Lamond teaching hard personnel decisions with a single whiteboard exercise.
⎯
These mentors guided Kevin throughout his career, helping him avoid common entrepreneurial pitfalls. The one regret Kevin did have, though, “revolved around not staying the course or enduring things for a longer period of time.” It was back in 2015, when Xoom’s billion-dollar sale to PayPal had seemed like “a great outcome” in the moment—but “fast forward ten years,” and the market “just kept getting bigger and bigger.” And now in 2025, Remitly and Wise—two small Xoom competitors who had “stayed in the game and kept compounding”—were now worth over a combined sixteen-and-a-half billion.
The Hartz Values
Throughout the countless ventures Kevin has embarked on, he’s noticed two common values which thread through them all. The two same values that he and Julia emphasize to both their kids and to every founder they back:
One—the drive to learn. The curiosity that pulled Kevin through a history and applied earth sciences double major at Stanford, a Masters in history at Oxford, and now cutting edge hardware at Sauron.
Two—the drive for adventure. The thrill-seeking restlessness of an Orindan teen blowing up model boats, and the dauntless entrepreneur traveling around the world, working with different partners for Xoom.
Those two, for Kevin Hartz, are “the family values that translate over to any founder."
