Private credit is sitting on more than $2 trillion in assets, yet much of the infrastructure behind it still runs like it’s powered by fax machines and Excel wizards pulling all-nighters. Middle and back-office teams have been piecing legacy systems together just to keep the machine running. Inefficient? Absolutely. Expensive? Always. Ripe for a rebuild? Without a doubt.
That’s the world John Olesky and Josh Herrera knew all too well before they co-founded LendOS in 2022. Based in Miami, they didn’t set out to build a shiny fintech toy. They built the operating system private credit desperately needed. Loan servicing, deal management, trade management, document automation, it’s all wired into one cloud-native SaaS platform with APIs that connect to legacy systems and surface real-time portfolio visibility. It doesn’t just patch over the cracks; it resets the foundation and makes billion-dollar credit portfolios fully auditable and fully manageable in ways the old guard never could.
The market responded fast. LendOS officially launched in 2025 and quickly landed validation from asset managers, direct lenders, and third-party servicers. These aren’t startups tinkering in the sandbox; these are global institutions that can’t afford downtime. And when they bet on your platform early, it’s a signal the product is already meeting the demands of a trillion-dollar industry.
Now the company has fresh firepower to accelerate. LendOS announced its Series A, with Blackstone Innovations Investments, the early-stage arm of Blackstone, leading the round. Illuminate Financial and Liberty City Ventures also joined, with Liberty City Ventures bringing things full circle as the firm that incubated LendOS at inception. While the round size remains undisclosed, the quality of investors is what matters. This isn’t just capital, it’s strategic muscle and market validation.
The roadmap ahead is clear. LendOS will scale product development, expand its go-to-market reach, and build deeper integrations and analytics to widen its footprint across private credit. With investor representatives like Stevi Petrelli from Blackstone, Alexander Ross from Illuminate Financial, and Emil Woods from Liberty City Ventures now in the mix, the company isn’t just funded, it’s fortified.
Private credit has grown too big for yesterday’s tools. LendOS is proving the future of this market won’t be held back by outdated infrastructure. It’s not just keeping up with growth; it’s shaping how the next trillion flows.
