Calm/Storm Ventures

Calm/Storm Ventures is a European seed-stage venture firm with an explicit healthcare and digital-wellness thesis, headquartered in Vienna and active across European and selectively US markets. The firm has positioned itself sharply around digital health, mental health, women’s health, and consumer-driven wellness, with an emphasis on category-leading European founders building globally relevant companies. For healthcare AI founders, Calm/Storm is one of the most relevant European seed funds if your company sits in their thesis verticals: AI-augmented mental health, women’s health, telehealth, longevity, and consumer health products with a defensible clinical or behavioral component. Stage focus is seed and pre-seed, with check sizes plausibly EUR 250K to 1M and a willingness to lead. Founders who should approach: European seed-stage healthcare AI teams in mental health, women’s health, telehealth, and consumer wellness; founders who value a thesis-driven investor with category expertise and access to a strong European digital health network. Founders who should not approach: B2B clinical AI for hospitals, regulated medical devices, biotech, and US-only companies — these are outside the lane. Calm/Storm’s value-add includes brand, founder community, and downstream relationships with European Series A funds active in digital health. Entry path is direct application through their website (they actively review inbound), LinkedIn outreach to specific partners, or warm introduction through their portfolio CEOs. Their Twitter and LinkedIn presence are active and partner-led. Be prepared to articulate the clinical or behavioral evidence behind your product, because Calm/Storm has seen the consumer-wellness category thoroughly and will diligence claims rigorously.
