Where they've grown or pulled back
DownNothing recorded in 2026; sponsored 1 conference in 2023.
Counted per conference. 2026 is the latest year whose conferences have mostly happened. Tiers use the best tier each year; swatches show the path, oldest first. A conference counts as pulled out only when a later event published a complete sponsor list, since most events don’t say whether their list is complete.
New 1
First sponsored in 2025 or later.
- PyCon (national Python conferences)first sponsored 2025, unranked tier
Pulled out 1
Not sponsored since 2024 or earlier, though a later event published a complete sponsor list without them.
- EMNLP (Conference on Empirical Methods in Natural Language Processing)last sponsored 2023; the conference ran again in 2024–26
Once or on and off 1
No clear direction, or a gap we can’t confirm because later sponsor lists are incomplete.
- NeurIPS (Conference on Neural Information Processing Systems)once, 2024, Bronze
