## About

Thomvest was established in 1996 by Peter Thomson. The firm manages assets for the Thomson family, whose primary wealth source remains its controlling stake in Thomson Reuters. Thomvest deploys capital into venture capital, private equity, real estate, credit, and infrastructure. It executes through direct investments, co-investments, fund commitments, and SPVs. The firm maintains exposure across North America, Europe, Asia, and other regions. Confirmed holdings include a majority stake in Thomson Reuters held via The Woodbridge Company Limited. The firm employs professionals across its San Francisco and Toronto offices. Eugene Siklos oversees non-technology investing. Additional vehicles include Thomvest Properties in Dallas and a real assets portfolio spanning the United States and Canada. No operational events from the past 24 months appear in public records. Thomvest operates with a vertically oriented structure that pairs sector specialists with portfolio companies. This model supports ongoing board and operational involvement rather than passive fund commitments.
