This week my investment in profitable and rapid-growing E-Commerce & SaaS-Start-up Gruenspar.de was press-released. I`ve been knowing the company for a while since I studied together with Founder & CEO Sebastian Kotzwander. After a really tough bootstrapped start he managed to get the company now on a very promising growth path in the two synergetic business fields E-Commerce and SaaS for Energy providers. Grünspar.de increased revenues in 2011 10fold and is my first investment in a company from my “home” city “Münster”
