I just googled "startup hooligans" :)
I didn't find anything – except this crazy agency: https://www.hooligans.co.il/.
Besides that – nearly zero Google hits – so, i guess, the term startup hooligans is still unused on this planet.
Unused terms are rare.
StartupHooligans.com is still available :)
Grab it if you can :)
