Building A $2 Billion SaaS Company: Lessons From A Two Time Founder
This blog post explores the entrepreneurial journey of Rujul Zaparde, detailing his experiences from FlightCar to Airbnb and beyond. It highlights key lessons in resilience, first-principles thinking, and the importance of diverse experiences in shaping a founder's mindset.
In the world of startups, few journeys are as enlightening as that of Rujul Zaparde, a two-time founder whose experiences span from dropping out of college to building and selling companies, and even working at Airbnb and Y Combinator. In a recent podcast interview with Dalton Caldwell, Rujul shared his entrepreneurial odyssey, offering a treasure trove of insights for aspiring founders.
The FlightCar Adventure
Rujul's story begins with FlightCar, a bold venture he co-founded while still in high school. The idea was simple yet revolutionary: offer free airport parking by renting out travelers' cars. This was pre-Uber and Lyft, a time when car-sharing was a novel concept. Rujul and his co-founders, young and undeterred by logistical challenges, launched the company with a scrappy, can-do attitude. They famously parked hundreds of cars at a BART station, only to be chased away by the BART police. This anecdote is a testament to their determination and creativity in overcoming obstacles.
Challenges and Lessons Learned
However, FlightCar's journey was not without its lessons. Rujul candidly discussed the challenges of running a low-margin, asset-heavy business:
"It's like squeezing the last drop out of a lemon."
This experience highlighted the importance of choosing a business model with healthy margins and taught him invaluable lessons about financial sustainability and the harsh realities of startup life.
Learning from the Best: Airbnb and Y Combinator
After FlightCar, Rujul joined Airbnb as a product manager, where he learned the inner workings of a successful company. He reflected on the importance of understanding how great teams operate and the need to avoid self-inflicted organizational pain. His time at Airbnb was a masterclass in product development and team dynamics, experiences that would later inform his approach to building his next company.
Rujul's journey took another turn when he became a visiting partner at Y Combinator, where he gained a unique perspective on startups from the investor's side. This role allowed him to refine his understanding of what makes a formidable founder and the critical importance of resilience and adaptability.
Building Zip: A New Venture
When it came time to start his next venture, Zip, Rujul approached it with a newfound clarity and purpose. He and his co-founder, Lou, spent two years ideating before launching Zip, a procurement software company. This time, they were determined to avoid market risk by focusing on execution risk, a strategy that paid off. Zip has since grown into a successful enterprise, raising significant funding and scaling rapidly.
Key Insights for Aspiring Entrepreneurs
Rujul's story is a testament to the power of resilience, learning from past experiences, and the importance of thoughtful decision-making. As Rujul aptly put it:
"It's my time. I just want to build something that people want that really works."

Actionable Takeaways

Rujul's insights underscore the importance of charging for enterprise software to validate market fit and focusing on high-margin businesses to avoid negative financial cycles. As he wisely noted:
"You want to set yourself up with a positive feedback loop, not a negative."
"If there's enough of a pain and promise of a solution, people should and will pay for it."
"It's just such a liberating way to think about things, to just seek truth."
