Financial Services San Francisco, CA 501–1,000 employees Founded 2009 Partnership

Sixth Street is a $125B+ asset manager running a finance-heavy operational backbone: 13 of 19 active hires are finance roles, and the tech stack reveals heavy reliance on Excel, AWS infrastructure, and Python for structured finance modeling. The project list—asset-backed financing, transaction workflows, investment valuations, and regulatory reporting—maps directly to pain points around compliance timing, accounting accuracy, and transaction cycle friction, suggesting the firm is automating manual processes that currently bottleneck deal velocity.
