Iovox is a startup specialising in something known as VaaS (Voice as a Service). Their telephony platform allows companies to build services on the telephone network that do real-world, heavy-lifting style jobs which normally require call centres. Companies which have taken on the service include News International and many others.
I went over to their West London offices (yes, not all startups in London are in the East, incredibly), to check out the legendary guitar playing skills of CEO Ryan Gallagher in our TechCrunch Europe version of TC Cribs. Maybe next time we should do a duet.
