Differ's business idea is to help scale up small-scale carbon reduction technologies (e.g. PV and energy efficiency) in developing countries through

• investing in start-ups (cash and sweat equity)
• developing our own concepts and companies
• advising project developers, project owners, investors and other decision makers to do the same 
• in-depth analysis on e.g. market conditions, feed-in-tariffs, financing and business opportunities in selected developing countries which will be distributed for free

The company was founded in November 2010 by entrepreneurs that previously have started and developed companies like Renewable Energy Corporation (REC) and Point Carbon.
