Shor Capital$100K–$500K
Baukunst$500K–$3M

Pre-seed-focused lead firm operating as a collective product-studio of creative technologists with hardware/frontier-tech experience, deeply building companies via recruiting, product strategy, early culture and pattern recognition for physical‑digital startups. Structured as a collective of creative technologists that blurs the line between venture firm, product studio, and creative community, founded by operators with deep hardware and frontier-tech roots who bring unusual pattern recognition to complex, design-heavy, physical-digital companies that software-first funds avoid. Their $100M fund deploys almost exclusively at pre-seed and will often lead entire rounds themselves, treating pre-seed as a full-stack company-building phase where they engage deeply on recruiting, product strategy, and early culture rather than treating it as an option on a later priced round.

Research briefRead more
Bolt Venture Capital Research Investment Thesis Bolt invests at the intersection of the digital and physical world, with a specialized focus on hardware-enabled startups that combine software with physical goods. Founded in 2013, Bolt operates as a pre-seed and seed-stage venture capital firm dedicated to supporting entrepreneurs building transformative hardware solutions. The firm believes that the best hardware companies emerge from teams that deeply understand both manufacturing, supply chain, and software—and that venture capital can add significant value beyond capital through operational expertise, manufacturing partnerships, and strategic guidance. Bolt's thesis is rooted in the belief that hardware founders benefit from hands-on support with prototyping, design, manufacturing, and fundraising strategy. The firm operates a million-dollar prototyping shop and employs experienced hardware engineers on staff, positioning them as product partners rather than passive investors. Stage Focus Bolt primarily invests in early-stage companies: Pre-Seed/Seed : $100K-$5M (most common check size) Series A : $5M-$15M (selective follow-ons and leads) Series B+ : Occasional follow-ons in strong portfolio companies The firm leads or co-leads first rounds in over 90% of portfolio companies, demonstrating their strong conviction and ability to move quickly on promising opportunities. Check Size Average check size : $250K-$1M for initial investments Range : $100K-$5M for first institutional rounds Typical seed investment : $1M-$3M Series A participation : $5M-$15M Lead Tendency Leads - Bolt leads or co-leads the first round of financing in over 90% of portfolio companies.
