The problem is that what I'm building is a function as a service platform, a general development tool. So developers/managers are the target audience. I think it's a matter of finding the “BANT” (budget, authority, need, timeline) requirements the article mentions.

Why not use this time to "sell" us your function as a service platform? You keep saying its a function as a service platform, but I still have no idea what it is or why it would be useful. I think you're missing a perfect opportunity to tell us more and get feedback from your potential customers (considering the HN crowd is full of developers/managers).
