Sequoia helps founders build companies from idea to IPO and beyond. Its expertise comes from nearly 50 years of working with founders like Steve Jobs, Larry Page, Jan Koum, Adi Tatarko, Brian Chesky, Anne Wojcicki, Eric Yuan, Julia Hartz, and Patrick Collison. In aggregate, Sequoia-backed companies account for more than 25% of NASDAQ's total value. Since its inception, the vast majority of the money Sequoia invests has been on behalf of non-profits and schools like the Ford Foundation, Mayo Clinic and MIT, which means most of the returns it generates benefit these great causes.
