Robert Glaser
Robert Glaser co-founded RealNetworks in 1994, a company that became synonymous with early internet audio and video streaming. He built the firm through the dot-com era and later turned to venture investing through his family office in Seattle, Washington. The family office concentrates on Seed-stage direct investments and SPVs, focusing on Marketing & Sales and Media & Entertainment opportunities. Known deals are sparse and not publicly detailed; the office appears to operate as a single-family vehicle backing startups alongside other angels or small funds. North America is the confirmed geographic focus. No team size or additional offices are publicly listed. The office does not disclose AUM or deployment figures. No philanthropic vehicles, club memberships, or co-investor networks are named in public sources. As a single-family office tied to one technology fortune, the firm's structural differentiator is its small, direct-only approach — it deploys capital without a large team or intermediary fund structures, relying on Glaser's network and experience from building a public software company.
