The California venture studio is trying to turn company creation into a repeatable discipline. Its wager is that AI, a distributed crowd and ruthless early validation can make the startup lottery a little less random.
It began as one billionaire's quiet family office. Today General Atlantic writes some of the biggest checks in private markets - and it still calls itself a partner, not a boss.
Liberty Partners backs the people who buy small companies and stay to run them. In healthcare, B2B services and financial services, its bet is that owners who fix boilers and read board decks build more durable businesses than spreadsheets alone.
For four decades, a Beverly Hills firm has invested in middle-market companies by lending and owning at the same time. In July 2025 it closed its seventh flagship fund at over $3.6 billion - proof the contrarian model still sells.
For 35 years, Connecticut has run a venture fund out of the statehouse. In fiscal 2026 it returned a record $66.5 million - proof that a government can, occasionally, invest like a Sand Hill Road firm.

For 40-plus years, Harvest Partners has bought unglamorous middle-market companies and held them long enough to matter. Here is how a relationship-first shop on Park Avenue turned patience into a $20-billion franchise.
Tony Pritzker turned a family fortune built on Hyatt and the Marmon Group into a private equity firm that sells patience - and just raised $3.4 billion on the promise it will not rush the exit.
A Palo Alto fund turned an alumni network into an asset class - if your startup wants in, someone in the founding story has to have walked through an Oxford quad.
Rudy Larsen skipped college, started a lawn-care crew in 2006, and turned it into a Utah family office that now buys, builds, and runs a portfolio of service and tech companies. The pitch is unusual for money managers: they would rather be in the truck than in the boardroom.
SoftBank Investment Advisers manages the biggest technology funds the world has ever seen. After a decade of writing nine-figure checks into startups, it is now pointing that firepower at one thing: the full stack of artificial intelligence.
Justin Dye grew Albertsons by tens of billions. Now his Boca Raton firm buys seafood distributors, RV power tech and cannabis lenders - and runs each one like an operator, not a spreadsheet.
