Our Fund

Brightstone is an early-growth stage venture capital firm based in Minneapolis. Since 1985, Brightstone has managed 11 venture partnerships, and we have been humbled to see the dramatic impact that our startups have had on the world. These companies share common beginnings- a few people banding together and taking a leap into the unknown. The heightened sense of excitement when pushing beta code to production. Discovering that the world wants to do something entirely different with a product. A nerve-racking decision to pass on a major partnership to stay focused on the mission. These are the moments we cherish being a part of, and we are grateful to our entrepreneurs for allowing us to be a part of their journey.

Brightstone currently manages a $100 million venture fund focused on early-growth stage investment opportunities. We leverage the deep operating experience and successful investment background of the Fund’s partners, primarily focused on investing in the following sectors:
