About Upstream

2024's theme: Unusual ideas to solve the usual problems

Improving the health and security of open source is an old problem. Yet here we are in 2024 and it is still not a solved problem. Upstream 2024 will be a curated set of presentations and conversations featuring those who are pursuing exciting new approaches to improving open source health and security, those who are attacking a very old problem in very new ways. 

We’ll bring together open source maintainers and those who use their creations alongside government leaders, thought leaders, while also gaining inspiration from visionaries tackling parallel challenges in other fields.

Our hope is that those who attend come away refreshed, rejuvenated, and with new energy to tackle ensuring the security and resilience of the open source software we all depend on in new, unusual, and exciting ways.

Check out the full theme announcement blog post from Tidelift co-founder Luis Villa.

We look forward to seeing you there!
