About Us Rengo AI is transforming the way alternative investment managers ingest and manage their data. Private markets are expected to grow to more than $24 trillion in assets in 2028, yet firms are still relying on a patchwork of legacy software, physical paperwork and manual spreadsheets for daily operations.

We’re building a modern data platform that equips managers with the infrastructure they need to focus on what matters most, delivering returns for their investors. We’re backed by leading venture firms and strategic investors and are partnering with some of the largest alternative investment managers to design and bring this platform to life.

Our team combines deep experience in fintech and alternative investments. We’ve built startups from the ground up, led quantamental engineering at a $70B hedge fund, and overseen valuations and portfolio monitoring at Goldman Sachs. Now, we’re bringing that expertise together to redefine how investment managers run their businesses.
