Amazon Web Services sent speakers to the widest spread of conferences: 12 of 12 circuits, 85 conferences
Ranked by the number of circuits where the company had at least one speaker (bar, out of 12), then by distinct conferences (second figure, out of 155, with the 18 small regional PGDays counted as one).
How these are counted
- Events per year: one count per event, whatever its format; cancelled events are left out.
- Attendance: the event whose id is the conference plus year (e.g. data-ai-summit-2024), so regional spin-offs are excluded. Figures are as reported; virtual registrations are not included.
- Prices: per event, the standard, regular or general full-conference rate; discounted, early-bird, door, VIP, training and expo-only tickets are skipped. Non-USD prices use fixed rates (EUR 1.1, GBP 1.3, AUD 0.66, CAD 0.73…).
- Sponsor categories: each sponsor slot takes the company's jev product category when jev's confidence is at least 0.5; "not a vendor" and "other software" are dropped, as are cloud-provider events and the Snowflake Summit 2026 event. 2023 is left out to compare two clean periods.
- GenAI talks: talks whose jev topic is GenAI & agents with confidence at least 0.5, divided by all talks with a topic.
- Countries: events with a known country, not cancelled, 2023 to 2026.
- Speaker companies: appearances where the speaker's affiliation resolved to a company; ranked by circuits reached, then distinct conferences, with the 18 regional PGDays counted as one conference.
