In 2020, Ari Rubin was juggling two lives: one as a landlord managing single family rentals, the other as a hedge fund manager pulling 82% annualized returns on a $150M fund. He had the spreadsheets, the grit, and the sleepless nights to prove it. But he also had a problem: active property management was the one asset that refused to be passive. So, he did what real founders do, he didn’t just build a startup. He built a damn solution.
Flock Homes was born in Denver with four homes and one relentless mission: give landlords an offramp from the chaos without selling their soul, or their real estate. Fast forward five years, and Flock’s now managing over 860 homes across 17 states with close to $200M in real estate under management. That’s not luck. That’s execution, at scale, with precision.
Yesterday, Flock dropped a Series B bomb, $20M led by Renata Quintini of Renegade Partners, with repeat hitters like Andreessen Horowitz, Primary Venture Partners, Susa Ventures, and 1Sharpe Ventures doubling down. This round isn’t just fuel. It’s a signal. A green light to move beyond single family and into multifamily and manufactured housing. A strategic evolution that transforms Flock into a retirement runway for landlords holding the bag on $6-8 trillion in trapped equity.
The beauty? It’s all powered by a tech-enabled 721 Exchange platform that turns tax headaches into 24-hour digital smoothness. Think instant valuations, automated compliance, and a fund structure that feels more like a Wall Street REIT than a suburban side hustle. And behind the curtain? A team of 39 pros, half in Denver, led by Ari, backed by board legends like Alastair (Alex) Rampell (a16z), Brad Svrluga (Primary), and Renata Quintini.
Kansas City? 89 homes, $19M in value. Phoenix? Just added five Mesa homes for $2.2M. And this isn’t just about doors, it’s about data. Flock’s rental ops clock in at 5% economic vacancy, 7% loss to lease, 2% credit loss. Try finding a mom-and-pop landlord matching that.
But what really sticks? Flock isn’t selling exits. They’re selling freedom. The kind that lets aging landlords keep their income, defer taxes, and ditch the midnight plumbing calls. The kind that speaks to the $84 trillion wealth transfer racing down the pipe toward a generation that wants real estate returns without the real estate headaches.
Flock isn’t flying under the radar anymore. They’re soaring with a blueprint that blends institutional polish with entrepreneurial fire. So, landlords: if the dream was always passive income and no management migraines, this just might be your moment to migrate.
And to Ari Rubin and the Flock crew, congrats on the Series B. The nest is built. Time to scale the skyline.
