Where they've grown or pulled back
Sponsored 1 conference in 2026, the first year on record.
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 2026, tier not listed
Not on the company map: lookalikes are computed only for companies present at four or more conferences.
