Bolt is a venture capital firm designed to address the unique needs of early-stage startups at the intersection of hardware and software. Most institutional investors have moved upstream and back hardware companies that have completed product development. Bolt fills the gap in early stage hardware financing, investing in pre-seed, pre-product companies.

We believe capital is a commodity and people are not. We believe people are at the center of great products and great products are at the center of exceptional companies. We love lean, technical teams and thrive on helping founders bridge the gap between idea and product/market fit. An investment from Bolt brings a full stack team devoted to helping you get to market faster, raise smart follow-on capital, and build a foundation for success.
