Exertris

I founded Exertris in 2000 and was CEO until 2004. We were all devastated when we were forced to admit defeat and closed the company in 2004, unable to make it profitable. I'm still enormously proud of what we achieved. It was a truly inspiring four years working with some extraordinary, talented people including our unbelievably supportive investors.
