Live Mocha and Rosetta Stone
Here is a financial statement for Rosetta Stone over four years ending Dec 31 2009. I find it interesting to see that they report spending almost 70 million dollars on Research and Development!
I have not been able to find similar information on Livemocha, although I think they are a publicly traded company. I could be wrong.
I believe that 90% of Rosetta Stone’s market is in the US, and 90% of LIvemocha’s users are outside the US.
In LingQ’s case about 25% of our members live in the USA.
