The annual Debian developers' conference (DebConf) typically needs 150.000-200.000 USD raised from sponsors to cover the cost of the conference and the bursaries granted to attendees. The DebConf fundraising team strives to provide adequate funding to each annual conference. It also ensures that sponsors' perks are delivered as promised during the fundraisers.
The DebConf fundraising is not yet integrated with the Debian fundraising but the DebConf fundraising team exchanges regularly with the Debian partners team, DSA, the DebConf Video team and other teams that work with Debian sponsors or have demands for specific donations (e.g. hardware).
The workflow for each individual sponsor ensures that the decentral members of the fundraising team can coordinate across diverse timezones.
