Going through our pre-seed round atm and it is incredibly frustrating. I haven't raised in the US so it may be similar there, but the amount of time wasted for a relatively small amount of money is painful.
I'm also not sure what the government can do. SEIS/EIS is a great scheme, but the SEIS limit of £250k feels almost too small to do anything meaningful, and EIS funds are generally later stage or re-investment from SEIS.
