Sequoia Capital is a prominent global venture capital firm founded in 1972 by Don Valentine and based in Silicon Valley. Renowned for its early investments in transformative technology companies that have shaped the modern digital economy, the firm has backed iconic startups including Apple (1978), Google (1999), Cisco Systems (1987), Oracle (1980s), YouTube (2005), WhatsApp (2011), and more recently, invested in FTX at a $32 billion valuation. Sequoia's investment strategy focuses on seed, early-stage, and growth-stage funding primarily in the technology and cybersecurity sectors, with a portfolio spanning software, consumer internet, enterprise, and emerging technologies such as AI and biotechnology. The firm manages billions of dollars in assets under management and operates with a long-term partnership approach, often taking board seats to guide portfolio companies. In recent years, Sequoia has expanded globally, establishing dedicated funds for regions including China (Sequoia Capital China, founded 2005), India/Southeast Asia (Sequoia Capital India, 2006), and Israel, while maintaining its core U.S. operations. In 2023, Sequoia announced a restructuring to create separate entities for its U.S./Europe, China, and India operations amid geopolitical tensions. The firm continues to invest actively, including as the lead investor in NeuralTech Systems' Series B round in March 2024, underscoring its ongoing commitment to cutting-edge technologies. Despite its successes, Sequoia has faced scrutiny over some investment choices, particularly in companies involved in data privacy controversies or aggressive growth tactics, though the firm itself has largely avoided direct legal entanglements. Sequoia's influence extends beyond financial investments into the broader ecosystem of innovation and entrepreneurship, playing a pivotal role in Silicon Valley's development.
