39B kWh of energy ($3.8B in dollars) are wasted annually by US data centers. We are building a solution for the problem in stages. First stage is ready: Cloud Capacity Controller. It starts and stops virtual machines right when you need it to minimize your costs and maximize utilization of cloud resources. This technology allows you combine different machines with different prices and reliabilities (Amazon EC2 and Spot instances) to get the best out of your cloud at the minimum cost.
