Side Door Ventures

Side Door Ventures is a global, generalist venture capital firm investing in early-stage technology companies across sectors and geographies. The firm backs founders from seed through later growth stages, with a stated focus on cross-sector businesses that do not map neatly onto a single vertical. Its investment activity spans software, life sciences, space technology, frontier technology, blockchain and Web3, gaming, and financial services.

The firm operates four fund strategies. The Seed Fund makes early-stage investments across sectors. The Michigan Fund backs seed-stage companies headquartered in Michigan. The Digital Asset Fund invests in Web3 companies. The Opportunity Fund supports fast-scaling Series A and later businesses, providing a mechanism to follow on into companies showing rapid growth after initial backing. The structure allows the firm to participate across a company's lifecycle rather than at a single entry point.

Geographically, Side Door Ventures describes its presence as global, with identifiable activity in North America and a specific mandate covering Michigan through its dedicated fund. The team is globally distributed and includes former founders, biotech scientists, space engineers, and growth specialists - a composition that reflects the breadth of the sectors covered.

For candidates, the relevant characteristics are the generalist, multi-stage approach and the diversity of technical domains under active investment, ranging from life sciences and space technology through to digital assets and gaming.
