Current / upcoming sponsorships

These sites in the network are sponsored through the formal site sponsorship program (ordered by start date, end date, then site name):

Site Company Start date End date
Salesforce Gearset July 1, 2021 March 31, 2024
Quantum Computing AWS January 16, 2023 January 16, 2024
DevOps Hashicorp May 25, 2023 December 29, 2023
GenAI Stack Overflow Labs July 25, 2023 unspecified
Game Development WB Discovery November 29, 2023 May 29, 2024

Additionally, three sites are sponsored informally, under special agreements that were negotiated before SE launched the formal site sponsorship program:

Site Company Start date
Ask Ubuntu Canonical (more information) October 11, 2010
Ask Patents U.S. Patents & Trademarks Office September 20, 2012
CS50 edX somewhere before May 2014
