It's covered in the paper, but the origins are the "crosvm" project at Google, which is used in ChromeOS. Firecracker started as a fork of crosvm, removed a bunch of code they didn't need, and of course adding their own.

This has allowed other similar tech to grow, like https://github.com/cloud-hypervisor/cloud-hypervisor, which seems to be the Intel project mentioned in the above sentence.
