Favorite Business Model
Fred Wilson's Favorite Business Model:
"Give your service away for free, possibly ad supported but maybe not, acquire a lot of customers very efficiently through word of mouth, referral networks, organic search marketing, etc, then offer premium priced value added services or an enhanced version of your service to your customer base.
Examples:
Skype – basic in network voice is free, out of network calling is a premium service
Flickr – a handful of pictures a month is free, heavy users convert to Pro
Trillian – the basic service is free, but there is paid version that is full featured..."
