At the moment we’re going through the process of ISO registration in my “day” job.
From what I can see, there’s nothing to prevent an Intuitive from going through the process. Probably not worth the bother, but the concept amuses me.
On a somewhat related note, there’s some government grants around for small businesses. We applied at the day job and were refused, apparently there’s an element of random selection. But the Intuition business was accepted! We have a £2,000 government voucher for business advice. I don’t think we’ll use it though – can you imagine the headline if the Daily Mail found out…?
