About Vital Stage
Vital Stage appears in public sources as VitalStage Ventures, a firm and not a solo angel. Third-party profiles describe it as an AI-native venture firm founded in 2024 and based in San Francisco. One profile also lists an office in Reno, Nevada.
The firm's website names Brian Shin as Managing Partner. Fumi Matsumoto and Waikit Lau are listed as Venture Partners. The site also lists an AI advisory board that includes Raj Aggarwal, co-founder of Pedestal.ai. It describes the team as entrepreneurs and AI builders. Detailed employment histories for the team are not on the site, so they are not covered here.
The firm says its mission is to help AI founders through each stage of AI innovation, from inception and product strategy to launch, pivot, growth and exit. It also says it is building a community of responsible AI leaders, builders and policy makers.
The firm's website says it has backed over 50 technology companies, including HubSpot, Lightmatter, Drift, HqO and Kayak. One third-party profile attributes some of these exits to Brian Shin's earlier angel investments. The site does not give years or round details for them.
