Amberstone Ventures

Amberstone Ventures is a San Francisco-based venture capital firm founded in 2019 with $50 million in assets under management, focused exclusively on investing in disruptive consumer product companies serving wellness needs for next-generation consumers and families. Managing Partner Alexander R. Bernstein and General Partners James Graham and Nicolas Mindel lead the five-person team, combining rigorous data-driven analysis with extensive consumer packaged goods experience to identify brand-first companies with genuine consumer resonance. The firm invests at pre-seed and seed stages with checks of $500,000 to $10 million, targeting companies with less than $15 million in trailing revenue and strong indicators of category leadership — authentic brand positioning, compelling revenue growth, healthy margins, and strong retail velocity. The portfolio of 13 companies includes Honey Mama's, JuneShine (hard kombucha), Clean Skin Club, and Bloom Nutrition. A second fund is actively investing, and Amberstone is targeting $90 million for its newest vehicle. Amberstone's investment thesis rests on the view that the next generation of dominant consumer brands will be built differently — with brand authenticity and community at the foundation rather than legacy distribution and mass marketing. The firm's approach combines the analytical rigour of quantitative data assessment with deep qualitative judgment about brand-market fit, allowing it to move decisively at the earliest stages when consumer momentum is first becoming visible in retail velocity, social media engagement, and repeat purchase behaviour.
