www.proofofexistence.com - Any other big projects focusing on the ledger?

Before posting I did a couple of search and could not find much about this subject.

https://www.proofofexistence.com/ could be a small project. I do not know enough about the developer.

Having so much new investment pouring into bitcoin I was wondering if anyone is working on a serious tool using the ledger power of the bitcoin network.

If not why not?

There's another site that does this: https://www.btproof.com/

Both look like small one man projects though.
