About Diane Greene
Diane Greene co-founded VMware in the late 1990s with Mendel Rosenblum and others. She served as its first CEO, and the company was later sold to EMC for $635 million. She later ran Google's cloud unit.
After VMware she founded Datrium, a virtual storage startup aimed at cloud and service providers. GigaOm reported it was self-funded by Greene in its early days. Crunchbase also lists her as Chairman of the Corporation at the Massachusetts Institute of Technology. She is based in the San Francisco Bay Area.
PitchBook lists Greene as an active individual angel investor in San Francisco with 18 recorded investments and 9 exits. Crunchbase counts 19 investments. GigaOm described her as an active angel investor as early as her Datrium period.
Dated deals in PitchBook include Clinkle (seed, 2013), Cumulus Networks (2013 and 2018), Xperiel (2016), Xcalar (2017), Pilot (2018), Unit21 (2020), Meter (2024), and Korl and Samaya AI (both May 2025). Crunchbase also lists her as an investor in Cumulus Networks' Series A. PitchBook marks Clinkle and Xcalar as out of business.
Enclave: in March 2026, Enclave raised a $6M round led by 8VC. Greene was among the named angels, alongside Patrick Collison, Aaron Levie, Matt Huang, Jeremy Stoppelman and Marc Benioff. Enclave is a Tel Aviv-based application security company.
June AI: in August 2026, June AI emerged from stealth with a $20M pre-seed round led by Marc Benioff's TIME Ventures. Participants included Michael Dell, Aaron Levie and George Kurtz, and Greene was named as a participant. June builds software to deploy AI agents inside enterprise systems.
PitchBook also lists Samaya AI (May 2025) in her portfolio.
Her recorded investments cluster in enterprise and business software, networking, security and fintech, often at seed or early stage, and mostly in companies that already had revenue. Her two recent AI deals are in application security and enterprise AI deployment. Both were pre-seed or seed rounds led by other investors, with Greene joining as an angel.
She has not published a check size or a statement of what she looks for, so neither is given here. PitchBook shows her status as actively seeking new investments.
