Little help
We found our first couple of B2B customers were happy to take a (slight) risk with a startup as they knew they were getting a good deal and the investment was low compared to what they spend on the big players. I imagin it’s rare to start with a new companiy where the investment was so big in warranted being underwritten.
Simple tax breaks for new companies would make a real difference IMHO. R and D tax credits helped us.
