I have a project I'm playing with. Trying to figure out pricing.
Pain point: Hand writing notes sucks - especially if you have bad hand writing. But hand written notes are powerful. And leave an impression.
Solution: Email note@scendr.com with note. Include address of recipient. We write it on a plane card with gender neutral hand writing. Stamp it. Send it.
What would you pay for this? http://www.scendr.com
It's disingenuous and I'd have to fend off questions like the above. So I wouldn't buy it for any price.
That said, I'm one person and that's simply one person's opinion. It doesn't invalidate your idea so don't take this the wrong way (as an insult or personal attack). It's a fun idea, but not one I can see anyone who is "serious about business" using.
