Been a while since I was in this position but that first £100k used to be a cakewalk. SEIS made it almost a no-brainier for any high net worth individual to invest in startups.
and it still should, as I understand it. On a £100k investment that the business loses all of, the investor gets £75k (£50k tax relief + £25k-ish loss relief) back or something ridiculous, don't they? Makes me wonder how this hasn't made UK capital more readily flow
