Who Is Birju Kadakia?
Birju Kadakia grew up in the suburbs of Chicago using his local tennis courts and basketball gym without ever thinking of "community recreation" as a category. He studied engineering in Illinois, joined Uber as one of its earliest employees, helped launch Uber Eats globally, then led product at The Athletic before The New York Times bought it in 2021. In 2022, in the wake of COVID, he and co-founder Rachel Williams started Rec Technologies — a vertical AI platform rebuilding the software stack that runs municipal Parks & Recreation departments, YMCAs, gyms, and the broader "activity economy."
Four years in, Rec is live in over 100 cities, raised more than $17M with backing from Crosslink Capital and athlete-investors including Larry Fitzgerald Jr., Kevin Durant's 35V, and Andre Agassi, and is going live with 800,000-resident Indianapolis in the fall. They're displacing 25-year-old incumbents like ActiveNet and RecTrac by being AI-native — not by adding AI features, but by rebuilding the foundation so AI agents can actually do useful work.
What makes Birju interesting isn't the funding or the customer count. It's that he chose this. He's a Silicon Valley product leader with a long résumé who could have built anything. He chose the slowest, most unglamorous corner of municipal software because that's where he saw real people suffering through real systems — including his own kid's summer camp.
The Archetype: The Creator
The Creator
The Sage
Tests & Allies
Birju is a Creator first. His core drive is to build the thing that exists at the intersection of digital and physical — a pattern that runs through his whole career. He joined Uber because "it's so painful to get around in Chicago in the winter." He joined Uber Eats because his favorite restaurants weren't delivering. He started Rec because he couldn't figure out where to play tennis. Every move is about identifying a broken bridge between people and the real-world activities they want, and building infrastructure to fix it.
His secondary archetype is The Sage. Birju teaches naturally — he layered frameworks before examples throughout the conversation, walked through architecture decisions with patience, and his demos felt like he was genuinely enjoying explaining the why. The 50,000 hours his team has spent in city halls and Parks & Rec offices aren't a brag; they're a thesis. He believes vertical AI companies will only win if the founders are deeply embedded in the ecosystem. The Sage in him collects that knowledge; the Creator in him uses it to build.
"I love products that touch the real world. And I want to work in a space as a product leader where I'm talking to someone I don't work with, I'm talking to you, or I'm talking to my dad, and they understand what I do because it exists at the intersection of digital and physical."
The Hero Match
Frederick Law Olmsted
The 19th-century American who built the public recreation infrastructure no one knows is designed — Central Park, Prospect Park, the Biltmore Estate, Stanford's campus, the U.S. Capitol grounds. Olmsted's superpower wasn't aesthetic; it was the patient, multi-decade work of making cities physically capable of recreation. Birju is the digital-era version of the same instinct.
The parallel holds in three ways. Olmsted came to landscape architecture sideways through journalism, farming, and public health work; Birju came to recreation tech sideways through consulting, Uber Eats, and The Athletic. Both took long detours through unrelated industries before landing on infrastructure for community life. Olmsted believed parks should feel like found nature, not engineered space — and Birju said the same thing about Rec: "It doesn't need to be branded as AI — it will just get really great." Both believed the infrastructure should be invisible. And Olmsted's parks are still in use a century later because he built them slowly, with deep understanding of how communities actually use space. Birju is doing the same kind of patient, multi-year fieldwork — 50,000 hours in the field before scaling.
Leslie Knope — Parks and Recreation (NBC, 2009–2015)
Birju named his demo city Pawnee, Indiana, so this comparison was almost predetermined. But it actually works. Leslie's superpower is the religious conviction that local government infrastructure matters even when no one notices, and the willingness to grind through council meetings, permits, and zoning to make it happen. Birju is the builder-side mirror of Leslie — she fights for the swimming pool budget; he builds the software that makes the swimming pool sign-up work. Both believe recreation is civic, not just commerce. The version of Leslie that matches is the middle-seasons version: realistic about how slow change is, unshakeable in the belief that the work matters.
"It it it's so unique and interesting because you're working on a technology solution for people to be more efficient on screen so that they have time to spend outside." — Angelina Yang, closing the interview, with Birju jumping in: "Get off your screen. Get back to it. Yeah."
The Story Behind Rec
In 2022, on the back of COVID, Birju and Rachel started Rec with the obvious move for two ex-Uber Eats people: build a consumer marketplace agent that could hunt across all the broken city websites and book tennis courts for you. It was the right instinct from a consumer-product background. It would have been the natural play.
They killed it.
When they got into the work, what they found was that the data underneath wasn't a search problem — it was a wasteland. Cities ran on pen and paper, payments rails were a tangle of resident-rate pricing and income-bracket eligibility, schedule data lived in fifteen different systems. "AI is only as good as the data that has access to it," Birju said. So they pivoted to the unsexier play: build the data layer underneath the broken systems. Become the operating system for recreation operators first. Earn the right to the consumer magic later.
That pivot was the ordeal in Birju's hero journey. It's the moment a founder either commits to the slow work or runs back to the demo. He committed. Three years and 50,000 field hours later, Rec is live in over 100 cities, replacing 25-year-old incumbents, with the Refund Agent processing real money for real Parks & Rec departments.
The Founder's Journey ↔ The Company's Journey
Chicago kid using rec centers → Uber early employee → Uber Eats international PM → The Athletic Head of Product → almost built the marketplace agent → pivoted to the data layer → now building toward national infrastructure.
2022 pickleball-court booking for 10 cities → expanded into facility reservation, programs, memberships, learning → rebuilt the data layer → added AI agents on top → 100+ cities live, Indianapolis (800K residents) going live in fall → on track to be the operating system for the activity economy.
The same Creator instinct drives both arcs. Pick the boring infrastructure problem, build it patiently, let the magic compound on top.
How Birju Leads
Birju makes team-discovered strategic calls and founder-owned philosophical ones. When he narrates how Rec made decisions, the team is always in the frame — "we said," "we figured out," "we go to cities." When he narrates conviction, it's just him — "I love products that touch the real world." That split is healthy. People who work for him probably feel like they own the strategy with him and follow the conviction from him.
He's confident without hedging on the things he's earned the right to be confident about ("Some software is dead. You have to be a platform"), and humble about the things still in iteration ("60 to 80%, depending on the tuning"). Neither false modesty nor performance.
The core tension: Magic vs. Plumbing. Birju is drawn to consumer-magical moments — the dream of an agent that auto-builds your kid's summer schedule. But he's chosen a business where every magical moment requires years of unglamorous plumbing: codifying refund policies, building payment rails, integrating with legacy SaaS. The tension energizes him. It's why the work is slow, and why it'll last.
Founder Superpowers
Translating field reality into product architecture
Most product founders pattern-match the architecture from their last company. Birju derived Rec's three-layer stack (data → payments → agents) from spending 50,000 hours watching the actual work — pen-and-paper attendance, rain-cancellation phone calls, per-state refund policies. The architecture is a record of what he saw. That's a moat most founders don't have because they don't put in the time.
Sequencing strategy with discipline
"Pick a small problem to solve before you solve every problem." Most founders try to build the platform on day one. Birju picked pickleball booking in 2022 — the most specific, most boring possible wedge — and earned the right to expand from there. This is rare because it requires holding the big vision in your head while shipping something embarrassingly narrow. He does both.
Making AI feel trustworthy to non-AI-native buyers
The "suggestion-mode before automation" pattern, modeled explicitly after onboarding an employee. The Refund Agent first shows what it WOULD have done, the administrator confirms, and only then is automation turned on. That's the product instinct that lets Rec sell AI agents to Parks & Rec directors who've never deployed AI. The market access is built into the UX, not the pitch.
What It's Like to Work with Birju
He's a high-involvement collaborator. Fast pace, builds on other people's ideas, willingly extends tangents when the conversation finds something interesting. His energy gets stronger as the conversation goes deeper — by minute 60 of a 75-minute call, he was leaning in harder than at minute 10. That's not a hosting technique; that's who he is in rooms.
He's a teacher. He layered frameworks before examples throughout the conversation, took the time to walk through architecture decisions, and shipped three live product demos when one would have done. The Sage energy isn't ego — it's the deep systematic knowledge he's earned from 50,000 hours, and he genuinely seems to enjoy sharing it.
If you're an engineer or PM joining Rec, the bar is "embrace a little bit of all of it." Birju said it explicitly: "Be comfortable in the technicals" for PMs, "be more technical" if you're a designer, become "really deep at one thing but reasonably deep at the other things." The roles are colliding at Rec, and the people who thrive are the ones who can move across them.
"Our best engineers right now are managing many agents. And so they've become mini PMs running a team of engineers."
Why This Matters (For You)
If You're a City, Recreation Operator, or Activity Provider Evaluating Rec
Birju's framing of recreation as "the activity economy" — not a niche, but one of the country's largest industries — is the lens to bring to your evaluation. He doesn't think of Rec as software you install; he thinks of it as the operating system that makes everything you do downstream possible. The three-pillar defensibility (data, payments, infrastructure for equity and access) is the practical answer to "why this and not ActiveNet, RecTrac, or a custom build." If you're spending hours on rain cancellations, manual catalog production, or fighting per-class refund policies, Rec's bet is that those workflows can be automated end-to-end — but only on top of clean, unified data. Ask yourself: what would your team do if 60-80% of the routine workflow disappeared overnight?
If You're an Engineer Building Vertical AI
The architectural lesson from Rec is that vertical AI doesn't beat horizontal AI on model quality — it beats horizontal AI on owning the data, the payment rails, and the workflow context. Birju's three-layer stack (data → payments → agents) is a sequencing argument: you can't put agents on rotten data and expect them to be trustworthy. The "skills" pattern they use in Langfuse — codifying recreation-specific knowledge as system prompts that wrap the LLM tools — is a concrete pattern any vertical AI team can copy. And the hallucination strategy (codify policy as deterministic code, use LLMs only for inference where appropriate) is the way out of the trust trap that kills most vertical AI demos. Where does your current AI product mix deterministic logic with LLM judgment, and is that boundary drawn in the right place?
If You're Early in Your Career
Birju's arc shows what it looks like to take the long way through. Engineering school → consulting → Uber Ops → Uber Eats Product → The Athletic Head of Product → Rec CEO. Each role looked like a pivot at the time, but the through-line was always "products that touch the real world." He didn't have a five-year plan; he had a taste for a kind of problem. The career-design lesson is that direction beats destination. Pick the kind of work that energizes you, follow it through unrelated industries, and let the pattern emerge over a decade. His advice in the closing — "Speed. Time is your most precious commodity" — applies to your career too. If you're 25 and unsure, pick a thing and ship; the right path reveals itself in motion, not in deliberation.
If You're Considering Joining Rec
The team is around 35 people, hiring across go-to-market, deployment, product, design, and engineering. The culture is converging-roles: PMs ship code, engineers manage agents, designers structure systems. If you only want to do one thing, this isn't your place; if you like the mode where "everything is colliding," this is exactly your place. Birju leads with team-discovered strategy and founder-owned conviction — you'll feel ownership of how things get done, and you'll know where the philosophical lines are. He cares about the work mattering. If you want to build the unglamorous infrastructure that makes communities function, that's the bar.
