Let's see. Started a limousine business in India. Failed to evolve a system out of it. It began as a family business which was successful only if family members were working on it. The moment employees entered we used to make losses. So finally sold it when we were still profitable and my family members were still unsuccessful in their attempts to kill me.
This was followed by a few sustainability movements that addressed local environmental challenges in Bengaluru India.
Finally, began my own IT consulting firm which had to be closed down due to economic downturn and lack of projects.
I am hoping to begin something now to address the challenges of sustainability and climate change now. Shopping for ideas and killing them one by one for not being sustainable. Lol!
