A few of the interesting US companies:

* https://shone.com [SF] - $4.5M raised - watch assistance and navigation

* https://nautiluslabs.co [NYC] - $13M raised - commercial optimization

* https://cargometrics.com [Boston] - $22M raised - fleet management

All are hiring if I'm not mistaken. If you're interested in Nautilus you can shoot me a message. (disclaimer: I'm an engineer there, great company)
