David Senra

Travis Kalanick is best known for co-founding Uber and building it into one of the world’s largest transportation platforms. Before Uber, he spent years building Red Swoosh under extreme financial pressure. He says he took no salary for its first four years, repeatedly ran out of money and lost much of his social life to the company before eventually selling it. He later invested much of the proceeds in friends’ startups, becoming the first investor in Expensify.

Kalanick started Uber at 33 and carried the intensity of those earlier years into the company. He describes operating with “precision, perfection and obsession” and continued running Uber with the mentality of someone worried about making the next grocery bill even after the company had reached a valuation of roughly $70 billion. Under his leadership, Uber expanded rapidly across cities and countries, creating a new category of app-based transportation and challenging the entrenched taxi systems that controlled many local markets.

Uber’s growth depended on empowering young operators to build markets from scratch while maintaining tight control over the decisions that mattered most. Kalanick personally participated in the pricing process for the company’s first 20 to 30 cities, using each launch to refine a playbook that could eventually operate without him. He describes this management philosophy as finding the line between order and chaos: using the fewest possible rules while preserving the structure required to move quickly at scale.

After leaving Uber, he returned to company building within months. His current company, Atoms, is developing artificial intelligence and specialized robotics for industries including food, mining and transportation. Kalanick describes his role as “problem solver in chief,” focusing on the most consequential problems that are not already being solved and pursuing what he considers his broader calling: digitizing the physical world.

Lulu Cheng Meservey is the founder of Rostra and one of the world's most trusted communication strategists, supporting companies such as Anduril, Shopify, Cognition, and Coinbase. In 2016, she co-founded TrailRunner International with Jim Wilkinson, who had just run corporate affairs for Alibaba's record IPO. She had never done comms in her life. One of her first clients was Anduril, in the company's first year, when Palmer Luckey had just been pushed out of Facebook, and no reporter would give him a fair hearing. So they stopped asking. They went to Quantico, to Camp Pendleton, to the CIA, and showed people the technology directly.

She left to run communications at Substack, then joined the board of Activision Blizzard—and in October 2022 stepped off the board and into the company as chief communications officer. Microsoft's $69 billion acquisition was under attack from the FTC. She fought back in public, under her own name, which almost no executive in a deal that size is willing to do. It closed in October 2023.

In March 2024, she started her own firm, Rostra, and published Go Direct: The Manifesto. The first project out the door was Cognition's launch of Devin, the first AI software engineer. Shopify put her on its board that June. In December 2025, she raised a $40 million fund to back founders she believes in. She takes about a dozen clients at a time and has a waiting list of hundreds.

She named the firm after the Rostra, the speaker's platform in Rome, where a man could climb up while the city believed one thing and step down after it believed another.

Michael Ovitz⁠ is the co-founder of Creative Artists Agency (CAA), one of the most powerful and influential talent agencies in Hollywood history, built on a revolutionary approach to representation that fundamentally transformed the entertainment industry.

He is an entertainment executive and dealmaker widely regarded as one of the most formidable operators in Hollywood. During his time leading CAA, Ovitz represented virtually every major star, including Tom Cruise, Robert De Niro, Meryl Streep, Steven Spielberg, David Letterman, Barbra Streisand and many more.

Starting as a mailroom trainee in the 1960s and reshaping the power dynamics of the entire industry by the 1980s, he became known for his relentless strategic thinking, his creation of the "packaging" model that bundled talent for studios, and his ability to orchestrate deals of unprecedented scale and complexity. He built a reputation in entertainment circles through his fierce intelligence, relentless work ethic and his ability to build CAA into what many called "the most powerful company in Hollywood."

His major accomplishments include co-founding CAA in 1975 in an audacious break from the establishment, pioneering the packaging system that gave agents unprecedented leverage over studios, orchestrating landmark deals including the sale of Columbia Pictures to Sony, serving as President of The Walt Disney Company and building CAA into a multi-billion dollar enterprise that expanded far beyond traditional talent representation into sports, consulting and global entertainment infrastructure.

Micky Malka is the founder of Ribbit Capital and helped create Node, which he describes as the first digital art studio designed for digital artists. He calls himself “an entrepreneur at heart and an investor by design”—a deliberately broad description that allows him to resist labels, which is precisely the point. The one label he wants on his tombstone: “He was a rebel.”

In his mid-20s, Malka and his partners put all the proceeds from their first dot-com exit into starting Lemon Bank in Brazil. He says they nearly lost everything when the economy failed to take off. At its peak Lemon Bank operated roughly 7,000 locations and served 50 million customers while targeting Brazil’s large unbanked population. He later sold it to Brazil’s largest bank.

Years later, after meeting Walmart CEO Doug McMillon in 2019, Malka proposed that Walmart and Ribbit build a better financial-services business together. That effort became OnePay, which now provides payments, debit, credit and lending products across Walmart’s ecosystem.

At Ribbit, decisions are made as a group, no single partner is assigned to a company, and the team shares calendars, inboxes and emails. Malka confirms that Ribbit is his sixth company and says he intends to keep building it indefinitely. As he puts it, “The best entrepreneurs never have to sell their company.”

David Heinemeier Hansson (DHH) is the creator of Ruby on Rails and the co-founder of 37signals, the company behind Basecamp, HEY, and ONCE. He has spent 25 years building a software business around one condition: no one gets to tell him what to do.

Jason Fried hired him as a contractor out of Copenhagen for $15 an hour. He built the first version of Basecamp with just 10 hours a week — 380 hours in total — and still credits the shortage of time for how good it turned out. He does not trust himself with unlimited resources. Nobody should, he argues. Give a team too much money and too many people and it will build a blob.

Forty-some venture firms came calling in 2005. The only investor 37signals ever said yes to was Jeff Bezos, who accepted a term sheet priced so absurdly high they were certain he would walk. They have been sending him dividend checks ever since. Basecamp has been rewritten three times, and the original 2004 version — discontinued in 2010 — still runs and still makes millions in profit.

His marketing strategy, borrowed from Kathy Sierra, hasn't changed in two decades: you can't outspend the giants, but you can out-teach them. His product test hasn't either. He builds the thing he wants for himself, and once he'd rather use it than anything else available, he assumes he isn't alone. That's how Ruby on Rails started. It's how Omarchy started too — the Linux distribution he’s spent thousands of hours making and gives away.

No investors. No board. And now, with Omarchy, no customers. He calls that last step a retirement from capitalism: still making things, still sharing them, with nobody holding a claim on his time.
