Multicloud is a term that gets thrown around a lot in the cloud native ecosystem. Its goal is to connect together data and services across all the different cloud platforms (and legacy IT systems too).
If the latter, then I agree that multicloud is not popular — most users pick one cloud and use that.
For Goasguen and his co-founder Mark Hinkle, the solution was to adopt the serverless paradigm in cloud computing — and in particular, the Functions as a Service (FaaS) model that defined the first wave of serverless (which we are still in).
AWS] Aurora is serverless, Cloud Run from Google is serverless, TriggerMesh is serverless.”
