FinTech platform LendOS raises Series A from Blackstone

September 22, 2025

LendOS, a FinTech platform founded in 2022 and designed for corporate debt operations, has announced the completion of its Series A funding round.

The round was led by Blackstone Innovations Investments, the early-stage strategic investment arm of Blackstone, with additional backing from Illuminate Financial and Liberty City Ventures. The total amount raised has not been disclosed.

LendOS provides a modernised platform purpose-built for the private credit market, covering loan servicing, deal management, trade management and document automation. Its system integrates with client infrastructure, enabling auditability and real-time visibility across portfolios, funds and facilities, while replacing the patchwork of outdated tools and manual processes.

The company said the new investment will be used to accelerate product development and to expand its go-to-market strategy.

LendOS officially launched its SaaS platform in 2025. Built on a unified, data-centric architecture, it supports a wide variety of loan types in a single system. The company claims this architecture offers straight-through processing, greater accuracy and enhanced workflow automation, giving institutions a system that adapts as markets evolve.

LendOS CEO and co-founder John Olesky said, “We’ve seen a growing demand from institutions seeking to finally have intuitive, powerful software they can rely on. 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.”

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

Blackstone Innovations Investments head Stevi Petrelli said, “We are thrilled to be partnering with John Olesky, Josh Herrera, and the whole LendOS team.

“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.”
