ROOT VENTURES MANAGER, LLC

Thesis

Root Ventures is a San Francisco-based venture capital firm founded in 2013, focusing on seed-stage investments in deep technology and hardware startups. Their unique approach involves underwriting "engineering risk" in technically challenging sectors, a niche often avoided by generalist funds. They back founders with strong technical backgrounds building foundational, defensible technologies. Their investment thesis centers on "wonky" startups tackling hard engineering problems, with specific interests in deep technology, AI, hardware, industrial tech, manufacturing, robotics, and science. Root Ventures primarily leads seed rounds, providing significant initial checks and maintaining substantial reserves for follow-on investments, demonstrating a commitment to long-term partnership. Their geographic scope is primarily the United States, with a concentration in the San Francisco Bay Area for robotics and hardware, and a wider US focus for developer tools and infrastructure software. They also make selective investments in Africa. The firm announced its fourth fund in November 2025, raising $190 million, bringing their total AUM to $325 million. Typical check sizes for seed investments range from $1 million to $3 million, with a minimum of $530,000 and a maximum of $3.2 million. They prefer to lead rounds and hold approximately two-thirds of each fund in reserve for capital-intensive hard-tech companies.
