What is Zapier's value-add when GPT can chain an arbitrary number of flexible API calls? Imagine if the GPT plug-ins directory is fed as input to GPT...
The problem with Zapier is all the individual accounts and contracts you need with dozens of companies in order to have them all communicating for a real business. SaaS fatigue is a real issue.
Sounds like a call for them to partner with Venminder or a similar business to manage all your SaaS from a contractual perspective, as well as some CASB (cloud access security broker) to handle onboarding, offboarding, and governance of an org's SaaS inventory. Legit problem, but SaaS isn't going away.
