"The guy who made enterprise procurement
the most interesting problem in Silicon Valley"
Harvard dropout at 17. Sold a car-sharing startup to Mercedes-Benz at 21. Mentored founders at Y Combinator. Then built Zip - the AI platform quietly running procurement for OpenAI, Anthropic, Snowflake, and Sephora.
Most people don't think about procurement. That's exactly why Rujul Zaparde built a $2.2 billion company around it.
The first time you notice procurement, you're filling out a purchase request for a $500 software subscription and six people are still arguing about it three weeks later. Finance wants a budget code. Legal wants a contract review. IT wants a security assessment. Nobody knows who approved what, and the vendor is sending daily follow-up emails.
Rujul Zaparde noticed that problem at every company he worked at. He decided it was fixable. In 2020, he co-founded Zip with Lu Cheng and Felix Meng - a platform designed to route purchase requests intelligently across every stakeholder, and kill the email chain forever.
Four years later, Zip processes over $107 billion in enterprise spend annually. OpenAI runs its vendor approvals through it. So does Anthropic. Snowflake. Sephora. Discover. The company that started as a better approval form is now the operating system for how enterprises buy everything.
"What is the best way to seamlessly secure approvals across finance, legal, IT, security and risk teams for a purchase request?"- Rujul Zaparde, on the founding question behind Zip
But the procurement play came after Rujul had already proved something harder: that he could build and sell a company, survive a failed acquisition process, and still want to start over.
At 17, he dropped out of Harvard to co-found FlightCar - a peer-to-peer car sharing service that let travelers park for free at airports while their car was rented out, fully insured, to other travelers. The idea was pure Airbnb logic applied to a different asset class. It worked. FlightCar grew to 180+ employees, 17 locations, and $40 million+ in venture backing before Mercedes-Benz acquired it in 2016.
Rujul built 16 rigorous criteria before launching Zip - including what he calls the "Bomb Test": would revenue still grow if the founders disappeared? Every single criterion had to clear before he'd commit. Then he cold-called the first 10 customers and charged real money - no warm referrals, no friendly intros - specifically to rule out bias in the product-market fit signal.
After Mercedes-Benz took over FlightCar, Rujul didn't immediately start another company. He joined Airbnb as a Product Manager, leading the search product and platform teams. It was the kind of role that teaches you how a scaled consumer internet company thinks about product velocity, user experience, and how small UX changes move billion-dollar metrics.
Then came Y Combinator - not as a founder this time, but as a Visiting Partner. He had already been through the YC machine twice: as a founder with FlightCar in W13, and now on the other side of the table, advising early-stage founders on product-market fit, growth, and how to survive the early chaos.
When he co-founded Zip with Lu Cheng - his former colleague from Airbnb - in 2020, the founding team had a rare combination: deep product instincts from Airbnb, startup survival experience from FlightCar, and a clear-eyed view of the enterprise market from years of watching YC companies hit procurement walls as they scaled.
Zip went through Y Combinator again in Summer 2020 - making Rujul one of a small group of two-time YC founders. By January 2025, Y Combinator was using him as a case study in founder resilience: "He dropped out of college to build FlightCar, worked as a PM at Airbnb, and later as a visiting partner at YC. Today, his company Zip has raised $370M and is valued at $2.2B."
Peer-to-peer car sharing at airports. YC W13. $40M+ raised. 180+ employees. Acquired by Mercedes-Benz, 2016.
Led search product and platform teams at Airbnb post-acquisition. Learned how product velocity works at scale.
Served as Visiting Partner at Y Combinator. Advising the next wave of founders from both sides of the table.
Co-founded 2020. YC S20. $2.2B valuation. The AI platform for enterprise procurement from intake to pay.
Rujul and Lu Cheng kept standing virtual meetings via Facebook Portal during the early days of building Zip in the pandemic. They sometimes forgot to mute during personal moments. It became a founding ethos: radical transparency, constant communication, no performance. That approach shaped how Zip's internal culture works - overcommunication as a feature, not a bug.
"Everything degrades over time. As a founder, you're always fighting to help your company move faster."
"Taking the right path is the happy path."
"AI holds the potential to dramatically improve ongoing procurement processes such as sifting through large data sets, conducting spend analysis, managing contract lifecycles."
"Employees often wonder not only how to begin the process, but how to secure all of the proper approvals - just to purchase technology and services."
Before FlightCar, before Airbnb, before Zip - Rujul co-founded a nonprofit called Drinking Water for India while still in school. His parents had immigrated from Central India. The project built freshwater wells in Indian villages. To date, they've constructed more than 50 wells, bringing clean water access to over 100,000 people.
It's the kind of fact that doesn't fit neatly into a pitch deck, and that's probably why it matters.
Rujul treats speed as a core company value, not a byproduct. He promotes managers from individual contributor roles - he believes people who understand the work lead it better. He fully unplugs on Saturdays for family time - a firm line that doesn't bend for funding rounds.
Before launching Zip, Rujul built a list of 16 criteria that every startup idea had to pass. Not 15. Not "most of them." All 16 - including the Bomb Test (would the business keep growing without the founders?). He validated Zip against every single one before making the call.

ESPN named him to their "18 Under 18" list when FlightCar was gaining traction - a rare athletic-world crossover for a startup founder.
Zip shipped 20,000 code changes and 500 customer feature requests in a single year. Rujul calls velocity a "core value" - the numbers back him up.
He went through Y Combinator twice as a founder (W13 FlightCar, S20 Zip) plus a stint as Visiting Partner between the two runs.
His parents immigrated from Central India. The Drinking Water for India nonprofit he co-founded as a student has been running alongside his commercial ventures for over a decade.
Zip's $190M Series D was led by Jay Simons - the former President of Atlassian who ran the company from 300 to 7,000 employees. The bet on Rujul was a deliberate one.
Saturday is sacred. Rujul doesn't work on Saturdays - full family time, fully offline. It's a rule that has survived multiple funding rounds and a pandemic founding story.
