Just a head's up, that link is broken. I think you may have meant: http://en.wikipedia.org/wiki/Van_Westendorp%27s_Price_Sensit...

Also, I just want to mention that if you have the ability to change your price rapidly then using a dynamic pricing API[0] might be better suited for determining the best price.

Thanks, your company looks good :)

but at a glance it doesn't seem to work for App Store / Google Play.

Plus, I'm not sure how it would work for our intended demographic.

I'll definitely keep it in mind, looks like a great tool in the startup toolbox.

Is your product for shopping carts only or can it be used with anything? What if for example i was selling something using something like gumroad or shoplocket?

Our product is just a REST API, so you could use it with anything. We have been building out integrations with shopping carts but I think Gumroad would be a perfect application for it.

Excellent. I look forward to trying it in the near future.
