Fused is a small web hosting firm headquartered in Chattanooga, Tennessee. Launched in 2003, they’ve grown steadily and now host more than 1,500 WordPress installs and 3,500 websites in 34 countries.
I’m one of their happy customers. David McKendrick and his team usually respond to emails within minutes (but to be fair, I very rarely need to contact them about anything). If you’re on the lookout for a web host, be sure to visit Fused to see the available plans.
