Scaleway out of France has been doing baremetal cloud nodes for years. I used them during the beta and they are fantastic (despite slight latency due to being in France). Their smallest baremetal node starts at €3/mo for 4 ARM cores/2GB RAM/50GB SSD. Pretty cool infrastructure to be able to auto provision physical nodes on demand, but I think it's a different use case from the whole lightweight serverless processes on demand thing.
