1. Developers are in short supply.

2. Non-developers are not in short supply, broadly speaking. Every business guy/girl and their mother wants to get into startups. Finance people, former consultants, you name it. These are all highly-credentialed, experienced people, too. Obviously, superstar salespeople and PMs are in high demand.

3. Startups would rather have as little on the job teaching as possible, because that would slow them down.

4. At all the companies I've seen, there is a roughly one or greater than one to one ratio of non-devs and engineers. So hiring numbers for non-devs and engineers would seem to be the same. However the supply of devs is highly constrained, so companies have to expend more effort recruiting engineers.
