Accoona
Accoona said it has over $100 million in financial backing from private investment funds. However they do have a fight on their hands. MSN for example is spending the total Accoona financial backing every 45 days in just marketing alone. We had played with their system and found it a hybrid of both Yahoo and Google results. Not bad in our opinion. We tested about 300 searches, virtually all of them came up on par or better than both Google or Yahoo.
We wish them all the luck and they are going to need it with how hard the search engine market is becoming. Overall though we suggest you try them out at http://www.accoona.com
