Root Ventures Research
Investment Thesis
Root Ventures is a deep tech seed fund composed entirely of practicing engineers and hardware hackers who explicitly underwrite "engineering risk" in technically challenging areas. The firm's core thesis is that the best technology companies are built by engineers who understand complex technical problems and have hands-on experience building hardware and software systems. They believe in backing "wonky" startups—companies tackling genuinely hard engineering problems that generalist VCs avoid because the technical risk is perceived as too high.
The firm operates from a philosophy rooted in the earlier era of Silicon Valley, valuing technical depth, hands-on problem-solving, and engineering-first approaches. Rather than chasing trends, Root Ventures partners deeply with founders to help solve the hardest engineering challenges. They serve as an "invisible employee" to technical founding teams, leveraging their own engineering expertise to de-risk product development and manufacturing at scale.
Fund History and Current Status
Root Ventures has evolved through multiple funds:
- Fund I ($77M, 2018): Initial deep tech fund
- Fund II: Mid-stage fund
- Fund III: Continued expansion
- Fund IV ($190M, November 2025): Latest fund, actively deploying with major LP commitments from University of Chicago, Adams Street, State of New Mexico, Loyola, DuPont Trust, and Brown Advisory
Fund IV was officially announced in November 2025 and is currently in active deployment phase. The fund targets $250M but closed at $190M with broad institutional backing including state pension funds and university endowments, reflecting strong confidence in the team's investment theses.
Stage and Check Size Focus
Root Ventures specializes in Seed and Series A investments, with selective pre-seed investments:
- Pre-Seed: $500K-$1M for teams with technical proof-of-concept
- Seed: $1M-$3M for companies with working prototypes and initial customer traction
- Series A: Occasional participation in follow-ons for portfolio companies
Typical check size: $1M-$3M with significant reserves held back for follow-on investments and bridges. The firm operates with patient capital, holding roughly two-thirds of each fund for multiple rounds of support to capital-intensive hard-tech companies.
Lead Tendency
Root Ventures leads most of their investments, taking board seats and deeply engaging with founders. They rarely follow, preferring to establish the relationship early and guide the company through critical technical and manufacturing milestones. Their hands-on approach means they are invested in the success of their portfolio companies from day one.

Portfolio Highlights
Root Ventures has invested in over 94 companies across multiple fund generations. Notable portfolio companies include extensive presence in developer tools (Zed, Okteto, Meroxa), robotics and automation (Dusty Robotics, Ruby Robotics, SixWheel), hardware and semiconductors (Particle, Radical Semiconductor), manufacturing (nTopology, Shaper Tools, Instrumental), and AI infrastructure (Adept AI, Patterns, Breakpoint).
Decision Process
Root Ventures operates as a partnership with key decision-makers being Avidan Ross, Lee Edwards, Kane Hsieh, Chrissy Meyer, and other partners. Decisions are collaborative, with deep technical diligence led by the partner team. The firm conducts hands-on technical due diligence, often requiring founders to demonstrate their technical depth and solve actual engineering problems.
Decision Timeline
The firm typically operates on a 4-6 week decision timeline for seed rounds, with faster cycles for pre-seed companies they're sourcing actively. Given their deep involvement in technical diligence, decision-making is thorough but not glacially slow.
Warm Introductions
While not strictly required, warm introductions from trusted sources significantly improve chances. Root Ventures values technical credibility, so an introduction from a respected engineer, previous founder, or domain expert carries weight. Cold outreach is possible but less effective than a warm introduction.
Founder Preferences
Root Ventures explicitly looks for:
- Technical founders - Engineers with deep domain expertise, not just business people
- Serial builders - Founders who have shipped products, built hardware, or run operations
- Problem-solvers - Teams that can articulate the core engineering challenge they're solving
- Persistence - Founders who understand they're tackling hard problems and won't give up
- Authenticity - Engineers building for the love of the problem, not just for exits
They avoid:
- Non-technical founding teams (the firm believes in engineers founding tech companies)
- Me-too consumer apps or trends
- Companies trying to apply AI as a band-aid to non-technical problems
Fund Status and Availability
Fund IV is actively deploying as of November 2025. The firm continues to source companies and make investments. With $190M raised and typical check sizes of $1M-$3M, the fund can support 60+ seed/Series A investments with meaningful follow-on capacity.
Competitive Advantages
- Engineer founders on the investment team - Deep credibility with technical founders
- Hands-on operational support - Partners actively engage in product, manufacturing, and scaling
- Hardware lab environment - Office with machine shops, lab equipment for technical problem-solving
- Network effects - 94+ portfolio company network of founders and engineers
- Patient capital approach - Willing to fund multiple rounds and provide bridges for capital-intensive companies
- Emerging tech tracking - Deep expertise in emerging technologies like robotics, semiconductors, manufacturing
Investment Process and Typical Terms
- Standard seed structure - SAFE or equity rounds ($1M-$3M)
- Follow-on capacity - Reserves 66% of fund for follow-ons and bridges
- Board seats - Typically takes board seat in led investments
- Involvement level - High-touch partnership with founders on technical problems
- Timeline - 4-6 week decision cycle for seed rounds
Geographic and Stage Flexibility
While primarily focused on Seed and Series A, Root Ventures will occasionally:
- Participate in Series B rounds for companies solving critical problems
- Invest in pre-seed when the technical founders and problem are exceptional
- Take follow-on positions larger than initial investment if company trajectory warrants
The firm's geographic preference for US with Africa selectivity may expand as Fund IV deploys, particularly given emerging deep tech ecosystems globally.
