I’m Dr. Marian Siwiak from Cognition Shared Solutions (CSS) LLC. My company is a boutique software shop selling custom solutions to corporations, especially to their research and development departments. As I spend considerable amount of time buying digital media, custom designs or geeky things as the part of my job, I've started to explore that market. It turned out, that many times I find the niche that waits to be filled and capitalized. My books cover exactly that - passive income sources based on science.
