Milo

I wish I had known about Milo when I wrote this post back in April of last year.  Milo's mission from their site:

Milo's mission is to track every product on every shelf of every store in real-time. We see ourselves as building a bridge between online and in-store commerce that empowers the consumer to access the best of both shopping worlds—all in one place.

Basically, with Milo, you can check in-store inventories and find the best in-store prices online.

Bridging the gap between offline shopping (a trillion dollar industry) and the internet is an enormous opportunity that Milo was able to take advantage of.

They started just a few months before I wrote this post, completed their Series A round in November of 2009 and were acquired this month by eBay for $75 million.  Nicely done.
