Background
Sequoia Capital is one of the world's most influential venture capital firms, founded in 1972 in Menlo Park, California by Don Valentine. It manages approximately $85 billion across funds covering the United States, Europe, Israel, India, Southeast Asia and China (the China business operates separately as HongShan). Sequoia has backed Apple, Google, Cisco, WhatsApp, Airbnb, Stripe, Nubank, Klarna and hundreds of other companies, generating returns that have defined Silicon Valley's venture model. Its European operations, launched formally in 2020–21, have invested in Mistral AI, Wayve, Poolside and a range of fintech and AI companies across London, Paris and Berlin.
Sequoia's investment model is known for backing early and holding long. The firm introduced the concept of scout networks and company-building support beyond capital, with dedicated talent, design and marketing teams. In the AI era it has moved aggressively into foundation models, backing OpenAI, Anthropic, Mistral, and Cohere at various stages. Sequoia's European team has shown particular interest in the London AI cluster. The firm does not depend on sovereign-fund signals to commit capital; it identifies and leads rounds based on its own research rather than following government or institutional investors.
In April 2026, Sequoia co-led the $1.1 billion seed round for Ineffable Intelligence alongside Lightspeed Venture Partners, in a pre-revenue, pre-product round staked on the research credibility of founder David Silver. The round is the largest seed in European history and positions Sequoia's European portfolio at the centre of London's AGI-oriented startup cluster. Sequoia's co-lead, without needing a government signal, confirms that American growth equity is the dominant capital at London's AI training tier, with the UK Sovereign AI Unit as a minority validator rather than a price-setter.
