Probably.

Whenever I've done calling or canvassing for progressive causes or democratic candidates we've used some version of NGP VAN (https://www.ngpvan.com/about).

I wouldn't be surprised if there are some cross-party solutions (especially the closer you get to core infrastructure—I'm sure both parties use AWS).

You are right, in the deepest recesses there is crossover. Stripe, media companies/FB for ad buys, Microsoft Azure, AWS. It is very rare anywhere else.

I would be curious to know if you would expect these companies to be partisan too? And if not, why?
