ThirdStream Partners LLC invests in venture and strategic opportunities across financial technology and financial services, deploying capital through principal investments that range from early-stage startups to later-stage private companies. The firm partners with companies working on financial markets, institutions and infrastructure. Its team's experience comes from firms that applied quantitative, computer-driven methods within the finance industry; prior to founding ThirdStream Partners, its principals led Barclays Global Investors, which at the time was a large quantitative investment management firm and was acquired by BlackRock in 2009. Alongside capital, the firm says it provides strategic insight, operational expertise and longer-term partnership to the companies it supports.
