Investment thesis
Rock River Capital is an early-stage, industry-agnostic venture firm focused on the Midwest. It seeks companies that have achieved initial product/market fit and are positioned for growth, typically those introducing a technical disruption to their industry, often via software. The firm structures founder-aligned, straightforward deal terms and prefers to lead rounds and take a board seat to add value where needed. It reserves significant capital for follow-on investment and partners with large Midwest venture capitalists to help portfolio companies advance to later funding rounds.
