After scanning the first page, I quickly noticed "Want something unique to your team? Tell us what you need."

I'm not a marketing guy (by any stretch) so maybe my opinion isn't worth much, but I think this is outstanding - provide something already useful, and then invite people to purchase your customized even more useful stuff.

It's always nice to see something well done — kudos!

(You seem to be focused on software development, but if you have anything along the lines of practical math used in a lab/shop/factory environment around machining, mixing, monitoring, testing, etc., It'd be great to hear about it)
