Investment thesis

Day One connects former Amazon employees into a global community that supports one another through connection, mentorship, events, and a Slack group. It leverages the Amazon alumni talent pool to create advantages for the founders and professionals it backs, positioning former Amazonians' tenure at the company as a springboard to future ventures. The group invests in and supports startups founded by ex-Amazonians, providing capital, advice, and access to a wide network of corporate partners and investors.
