LendOS Announces Series A Funding Led by Blackstone Innovations Investments

Next-gen platform modernizes corporate debt, specializing in private credit and syndicated loans; new capital fuels roadmap and customer expansion

NEW YORK, Sept. 18, 2025 /PRNewswire/ -- LendOS, a fintech platform purpose-built for private credit lifecycle operations, announced today that it has completed its Series A funding round, led by Blackstone Innovations Investments, Blackstone's early-stage strategic investment arm, with participation from Illuminate Financial and Liberty City Ventures. LendOS will use the funding to accelerate product development and scale go-to-market efforts.

Built for asset managers, direct lenders, and third-party servicers, LendOS brings a unified system for lending operations including loan servicing, deal management, trade management, and document automation. It streamlines workflows that are often spread across legacy internal tools, vendor platforms, and manual handoffs. The platform is built to integrate with existing client systems while delivering auditability and real-time portfolio visibility across funds, facilities, and counterparties.

"We've seen a growing demand from institutions seeking to finally have intuitive, powerful software they can rely on," said John Olesky, CEO & Co-founder of LendOS. "This investment enables us to continue to deliver on that promise by accelerating our roadmap and supporting a growing customer base that expects their software to evolve with them in the future."

"Lending has scaled rapidly, especially Private Credit, but middle- and back-office systems haven't kept pace," said Josh Herrera, President & Co-founder of LendOS. "LendOS gives institutions a modern operating layer—reducing cycle times, improving controls, and freeing teams to focus on higher-value work."

Investors highlighted the need for scalable infrastructure in private markets.

"We are thrilled to be partnering with John Olesky, Josh Herrera, and the whole LendOS team" said Stevi Petrelli, Head of Blackstone Innovations Investments. "Private credit requires purpose-built technology that can scale with the growth of the asset class. LendOS is building a platform to streamline loan operations and will help create a new data foundation for the industry."

"Private credit infrastructure is fragmented and outdated. The LendOS team combines unmatched credit expertise with a bold tech vision to redefine the modern credit stack and build the single source of truth for the market," Alexander Ross, General Partner at Illuminate Financial. "We look forward to working with LendOS to drive adoption across Illuminate's strategic partners and the broader industry."

"Backing LendOS in the Series A was a clear and straightforward decision," said Emil Woods, Founding Partner at Liberty City Ventures. "From day one, the team has demonstrated exceptional discipline, deep customer focus, and a relentless drive to execute. The traction speaks for itself, with rapid product velocity and strong client validation. We're proud to have played a foundational role in incubating LendOS and look forward to what's next."

LendOS launched its SaaS platform in 2025 and provides a future-ready alternative to legacy platforms. For institutions looking to modernize and strengthen their operations, LendOS offers a significant advantage over re-investing in outdated systems. Built on a unified, data-centric architecture, the platform supports a wide range of loan types in one system, enabling straight through processing, real-time portfolio visibility, and unmatched data accuracy across systems. Using this foundation, LendOS accelerates ecosystem connectivity and workflow automation – a system that works today and adapts to tomorrow.
