Activity by year
Three measures on one year axis; each panel has its own scale. 2027, 2028 is still mostly ahead, so its bars are faded and incomplete.
Conferences present at
Distinct conferences each year, split by whether the company sponsored or only had speakers there.

Where they've grown or pulled back
DownSponsored 1 conference in 2026, down from 5 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.
Pulled out 2
Not sponsored since 2024 or earlier, though a later event published a complete sponsor list without them.
- AI By the Baylast sponsored 2023; the conference ran again in 2025
- StanConlast sponsored 2024; the conference ran again in 2026
Steady 2
Sponsored in most years of its span at the same tier.
- PyDataevery year 2024–26, unranked tier
- SciPy Conference (Scientific Computing with Python)every year 2019–23, Gold
Once or on and off 4
No clear direction, or a gap we can’t confirm because later sponsor lists are incomplete.
