He was 87 years old. According to TechCrunch, death occurred due to natural causes.
Don Valentine was born in New York and received a chemist degree at Fordham University, but moved to San Francisco and got a job at Raytheon’s military-industrial company. He began to invest small amounts in technology companies, and this attracted the attention of one of the first mutual investment funds — Capital Group.
Having received $3 million from the Capital Group, in 1974 Valentine created the Sequoia Capital venture capital fund. Among his first investments were Apple and Atari. Valentine left Sequoia Capital in the 1990s and transferred the fund to Michael Moritz and Douglas Leone.
Other investments of the fund are Electronic Arts, Google, Cisco, Figma, Instacart, NVIDIA, YouTube, and others. Sequoia is one of Silicon Valley’s most profitable venture companies: after the Venture XI fund closed in 2014, revenue was 41% per annum minus a commission or $3.6 billion.
