For me, they can take a math approach to this. We still need to support start-ups. I'll say that to begin with. Start-ups are where scale-ups come from, but scale-ups are much less risky.
Once you pass a stage and become a 50- to 70-person company, have customers already, have a proven product, have markets internationally and have revenue, your probability of failure is much lower. Clearly, someone wants it. If you can use that as a metric to make investments, there's a reasonable risk there that the taxpayer probably could support.
