I haven't been following this sorry. I see this is doing the same that was done on the website so the comment is way late. I hardly see any difference between treatment of current sponsors/institutional partners and past sponsors and I think current sponsors should be much more prominently showcased. Otherwise I see little to no incentive for sponsors to continue being sponsors if when they stop sponsoring everything so close to when they are active sponsors.

I think it would also be nice to mention the sponsorship relation. Most of these are sponsors of pymcon webseries, which also had multiple tiers, and in general I think project sponsors or even better institutional partners are preferred (but harder to get)

While I go on about complaining and making requests. We also had sponsors from the first PyMCon edition: https://pymc-devs.github.io/pymcon/#sponsors and project sponsors from pymc3 times: https://github.com/pymc-devs/pymc/tree/c1e272c6454a1766523ee5ab5b7083fb100a1002?tab=readme-ov-file#sponsors (images don't seem to work anymore but the list had numfoucs, quantopian and odsc)

All being said, none of this are blockers the syntax is correct and renders as intended. So I will defer to the steering council to merge this as is, decide how past sponsorship should be recognized and request changes or open a project discussion (if we already did and I missed it just merge and ignore my comments).
