Starting Up

These are free ideas. On the off-chance you sell your company based on my idea for billions of dollars you can take me out for coffee. Really, really good coffee:

1. An API that tells you if someone is reachable on any device. Takes Skype, Gchat, Facebook, AIM, Google Talk, etc. and returns “YES” or “NO.”
2. A box for landlords/owners with a switch for every apartment they own/manage. Each switch has two positions: “rented” and “free.” Has a wireless connection to write to an online database with contact information.
3. A mobile app that pings you as you near a crowded subway station. You can curate a list of stations you care about.

Simple ideas are great. Simple ideas that fulfill a real physical need are better. Simple ideas that fulfill a real physical need AND can be easily prototyped and demonstrated are better. Owning an existing product based on one of these ideas is best.
