ATDC is a startup incubator company based in Georgia, US with headquarter in Atlanta's Tech, Square. The company has been around since 1979. Very old one will say but they are still very relevant in the market. In 2010, ATDC was among the top 10 technology incubator in the world according to the Forbes ranking.
The company has helped to develop many startups into successful companies. One good thing is that they are opened to all technology sectors and not sector specific.
Their programme is a 3years programme and i find this very encouraging as this will give the participants enough time to learn, go through demo and even practice their skill before coming into the real world of entrepreneurship.
