thanks for posting the link, I sat in on it.  Stephen Hunt, the presenter, was not the most inspiring or articulate individual while our technologies are clearly revolutionary. He fell short of capturing the excitement around these tech advances due to his subdued demeanour. Clearly as the cofounder of this business, he has the tech knowledge and understanding, however, perhaps the company could benefit from a polished senior marketer. He did mention that what is unique about Sparc is the fact that we have access and partnerships, in developing these technologies with universities and global players, which is unusual for such a small bespoke business. He also mentioned that the testing of the coatings products and exposure to potential customer markets has been a 'slow burn', however, they are now close to securing global customers.
