If you sign up, and you should see the prices
Why won't I sign up to find pricing? Because gaming pricing makes a bad impression and makes me think you will try to obfuscate other critical information once I become a customer and generally be a difficult vendor to work with. Nobody needs to add a difficult vendor, especially in a competitive category.
Edit: there are 6 top-level comments on this post besides yours. 4 of the 6 are looking for pricing.
We don't obfuscate, we care deeply about our clients. I always say this. If Preflight doesn't add value you don't have to pay for it nor use it.
Part of my first impression of your product is the fact that you have something to hide. I want to trust the products I use.
Also, my time is precious. I can't count the number of times I wasted time by looking at a product to find out the pricing makes no sens at all.
If I didn't care, I wouldn't have taken the time to write a comment as if I had a stake in your company beyond just wanting entrepreneurs to succeed. If I had seen this on Twitter, I would have just kept scrolling. But HN has given a lot to me, so I try to help others.
So in that vein, one more constructive criticism: learn to take feedback better. The best customer feedback often comes packaged in vitriol and is much more unpleasant than anything posted here. (Especially from support tickets. People are frequently angry when they write them, but they also provide invaluable insight into your product.) You'll have more success if you gracefully accept all critiques, both warranted and unwarranted, regardless of how gently they are phrased.
Good luck!
I don't care at all about anything else, as soon as the pricing page is hidden means it's not affordable to me.
