When Ali Dastjerdi and Nathan Ondracek first arrived as freshmen at Harvard University in 2015, the two had little reason to assume that their randomly assigned dorm pairing would evolve into something far more enduring than a college roommate arrangement. Neither could have predicted that their early friendship would one day become the foundation for a company—nor that they would eventually launch it alongside a third companion, someone they had yet to meet but who would soon become an equally indispensable part of their entrepreneurial journey.

Ondracek’s path crossed with Samuel Ilkka’s at Amazon Web Services, his first position after graduating. The two quickly recognized a shared approach to work, curiosity about technology, and a compatible sense of humor, which led them to become roommates in Seattle. Meanwhile, Dastjerdi was building his career remotely as an investor at Insight Partners. When the pandemic forced much of the world into isolation, he decided to relocate temporarily and share a home with Ondracek and Ilkka. The experience of simultaneously living and working together during a period of uncertainty transformed casual camaraderie into an intense and durable friendship cemented by shared goals, daily collaboration, and late-night problem-solving sessions.

By 2022, the trio decided to take a leap that would redefine their professional lives: all three left their jobs to cofound Raylu, an artificial intelligence startup focused on designing autonomous agents that help private-market investors automate the time-consuming process of sourcing investment opportunities. Their ambitious venture recently achieved a major milestone. On a Monday announcement, Raylu revealed it had secured $8 million in Series A funding—raising its cumulative total to $12 million. HighlandX, one of Raylu’s initial customers, led the round after testing the product, falling in love with its efficiency, and expressing a desire to become investors themselves, according to Dastjerdi. The company currently employs a compact team of 11, with clear intentions to nearly double its workforce to 20 by the coming January.

When asked about the key to their company’s momentum, the three 28-year-old founders were unequivocal: Raylu’s success is not separate from their friendship—it flows directly from it. To symbolize the unbreakable bond that sustains them, they keep a single unopened beer in their office refrigerator. Ondracek explained its meaning succinctly: “The day the company collapses is the day we drink that beer.” The gesture serves as a tangible reminder that while startups may rise or fall, their relationship is ultimately worth celebrating regardless of the outcome.

The story of Dastjerdi and Ondracek began as many college friendships do—with happenstance. Harvard’s freshman housing algorithm placed them together after the university’s extensive pre-assignment questionnaire designed to match students’ personalities and living habits. From that small stroke of chance, a deep and steady friendship grew. They pursued the same academic interests in computer science and statistics, stayed roommates for all four undergraduate years, and spent countless evenings developing business ideas—most of which fizzled out but nevertheless fueled their shared determination to create something together. Ondracek eventually chose Dastjerdi as the best man at his wedding, evidence of the personal closeness that preceded their business partnership.

When Dastjerdi later joined Ondracek and Ilkka in Seattle, he realized almost immediately that their combination of complementary skills, mutual respect, and intellectual ambition made for a once-in-a-lifetime opportunity. “Some people start companies because they stumble upon a brilliant idea,” he reflected. “We started ours because we recognized that having this group of people to work with was the real rarity.” Now based in New York, the founders operate from a WeWork office rather than a shared home, signaling both maturity in their professional setup and continuing balance in their long-term friendship.

Merging friendship and entrepreneurship is often considered perilous, yet the three were unafraid of potential complications. Before fully committing, Dastjerdi sought advice from a mentor who had previously founded a company with his childhood best friend. The mentor asked one revealing question: “If you and these two friends had the biggest argument imaginable, what would happen the next day?” Without hesitation, Dastjerdi responded that they would simply resume work as usual. His mentor told him such resilience was a promising indicator of their partnership’s strength.

Indeed, the advantages of their longtime friendship have proven significant. They operate with deep trust, recover quickly from disagreements, and understand one another’s unique temperaments, skill sets, and limitations. As Ondracek noted, their working rhythm resembles a sibling relationship—occasional tension, frequent laughter, but no enduring resentment. When prompted to describe each other, their balanced dynamic surfaced naturally. Ilkka characterized Dastjerdi as the embodiment of urgency and strategic awareness, someone attuned to the nuances of the investing world. He praised Ondracek as the most capable engineer he knows. In turn, Dastjerdi described Ilkka as the group’s optimist and the one most willing to embrace risk when circumstances demand bold decisions.

Still, navigating dual identities as both business partners and close friends requires deliberate effort. Dastjerdi admitted that one of his greatest challenges after launching Raylu was remembering how to be a ‘regular friend.’ With nearly all of his mental energy devoted to the company, he had to construct what he calls a “mental firewall” to prevent professional concerns from encroaching on personal interactions. Trust, too, has become an essential principle. Ilkka confessed that he had to restrain his instinct to micromanage. “I realized,” he said, “that I could spend my energy worrying about everything, or I could trust the people I chose to build this with.” This mutual confidence forms the quiet architecture that sustains their collaboration.

The trio has also acknowledged the importance of small victories. They intentionally pause to celebrate achievements—no matter how minor—because, as Ondracek observed, entrepreneurs often forget that no one else will celebrate on their behalf. These rituals of recognition help them maintain morale while reinforcing that their shared success belongs equally to each friend.

Reflecting on lessons learned from their journey thus far, all three founders distilled their experience into insights valuable to any aspiring entrepreneur. Ondracek emphasized that the essence of a successful startup lies not primarily in its product but in its people. “Nothing works if the people don’t work,” he explained. “Even perfect product-market fit cannot save a team that doesn’t function well together.” Dastjerdi added that early-stage founders should guard against becoming emotionally attached to any single idea too soon. He recalled the many prototypes and partial successes that taught them the difference between lukewarm user interest and true product-market fit: the latter feels unmistakable, as customers actively demand access to what you’ve built. His advice was clear—keep iterating, adapt quickly, and pivot often, because flexibility can lead to breakthroughs far larger than the original concept.

Ilkka contributed one final word of caution: do not rush into entrepreneurship out of social pressure or comparison. The decision to become a founder, he said, should arise from readiness and deep conviction rather than the mere observation that peers are doing the same. And if one chooses to embark on that path alongside close friends, he added, the ultimate measure of success is simple—when everything falls apart, make sure you would still be happy to crack open that one symbolic beer together.
