I think the bit the market doesn't appreciate with AIM is the "poles and wires" nature of a lot of what they do. Lexi is a bit like the proof of concept for automated captioning but this sort of enterprise/broadcast grade captioning is an intersection of various bits of tech and AIM, through that EEG purchase has put itself at the centre of it. So the market gets multiples larger and iCap becomes the infrastructure making it happen.
I assume the recent sell-off was because of the new iPhone that will have transcription built in. That is a world away from the products AIM offers, but demonstrates the markets lack of understanding, imo.
It's a solid purchase by Tony. As @mushroompanda said, you don't see that too often from the c-suite of a $70m company!
Ironically, the AI in AI-Media stands for Access Innovation, nothing at all to do with the current market fetish.
