Imagine your business was making a solid $1m/year in profit. But, if you had a one-time cash injection of $10m, there's a good chance you could expand to $5m/year in just 2 years. That's a risky but potentially profitable investment that is not interesting to big name VCs. It is an inefficiency on their part. But, their schedules are already overfull juggling the moonshots. I expect there are people working in that space, but they don't get a lot of press coverage.
