Overline

Investment decisions are driven by co-founders and managing partners Michael Cohn and Sean O'Brien. Cohn brings operating credibility from co-founding Cloud Sherpas and selling it to Accenture, plus running Techstars Atlanta; O'Brien brings transaction and strategy experience from 28 years in banking, hedge fund management, and corporate development at PGi. They are supported by a venture partner in Nashville, Brad Holliday, and a network of Operating Partners who engage directly with portfolio companies.

Overline sources heavily from the networks Cohn and O'Brien built through Techstars Atlanta, Endeavor Atlanta, and their own operating histories across the Southeast. The firm also runs a Venture Scout program recruiting scouts at Southeastern universities to generate early visibility into campus-founded startups. They state publicly that they review and respond to every pitch that comes from a Southeast-based founding team, treating inbound as an extension of their regional sourcing strategy.

Overline is structured as a traditional venture capital firm, not a family office. It was co-founded by two operators — Michael Cohn and Sean O'Brien — who together raised institutional capital aimed at backing early-stage technology companies. Its fund-based structure and active management separate it clearly from single-family office vehicles.

Overline targets inception and seed stages. The firm explicitly states it invests 'before the deck is polished, before the round is named,' and its stated check size of $250K to $1.5M is calibrated for pre-seed and seed rounds. It prefers to lead or co-lead those rounds, positioning itself as the first institutional capital in a company.

Overline invests as generalists across enterprise software, consumer, InsurTech, SpaceTech, and related verticals. Portfolio indicators include companies addressing property-casualty insurance deductibles, parametric disaster coverage, and cyber risk transfer, plus a space-economy company and a beverage brand. The firm does not publicly list excluded sectors, but its website and portfolio suggest a strong focus on software and tech-enabled businesses rather than deep-tech hardware or life sciences.

The firm's commitment to the Southeast is a binding investment constraint, not a marketing position. The partnership was built explicitly around the thesis that Southeast founders are undercapitalized at the earliest stages relative to coastal startups. Overline's co-founders helped build the Atlanta and Nashville ecosystems directly, and the firm's presence in Nashville, Menlo Park, and its Venture Scout program at Southeastern universities all reinforce a regional investment practice.

Overline commits time and network beyond capital, relying on an active Operating Partner network that joins founder calls and makes introductions meant to move the needle. The firm also draws on its broader community of founders and advisors, and the co-founders maintain active mentoring roles through Endeavor Atlanta and the alumni network of Techstars Atlanta, which Michael Cohn launched.
