Ask HN: What kind of specialist do I need for help pricing a SaaS product?

I'm building a SaaS product (who isn't anymore amirite?) and need some help figuring out the math on pricing an element of that product: data retention. Now, I could napkin math this thing and ensure it's profitable, but I'd probably over-shoot the cost and price myself out of the market. It seems other industries have underwriters (I think they're called? Or is that just insurance?) that help figure these things out but I'm not sure of the term. It seems this would go beyond just simple accounting and into data storage and market research, which I'm fine to do, I just want it done right which is why I'm interested in maybe hiring a specialist.

What kind of title/person should I be looking for that does this sort of thing professionally?
