If you are looking for a micro cap bio in the 'sweet spot' of introducing their already proven Global IP into the US market for 1st time have a look at CYC. Flying so far under the radar would even make the Dambuster boys 'pull up'.
Not a buy rec just FYI, garage holds a few in disclosure.
Also in disclosure Regal new addition to register some weeks ago so maybe a 'red light' to some.
