Value Add

Led by former executives from iconic tech companies (Apple, Microsoft, Compaq, Packard Bell) with direct operational experience building and scaling companies
Operators-first model: most team members come from technology, not finance, bringing 'perspective of people who have built, scaled, and led iconic companies from the inside'
Boutique firm structure with small team size ('we like being small because we believe venture capital doesn't scale') - every founder speaks directly with a partner
Willingness to invest in areas others avoid: hardware, consumer, and deep tech
Hands-on involvement including board or observer seats and proprietary network of European executives and operators
Strong track record: multiple unicorns, 2 IPOs (Riskified in 2021, Via in 2025), proven ability to support companies through significant growth
Deep expertise in European go-to-market expansion while maintaining global perspective
