"Mark and Tim worked with us through our Series A round of funding at Sourcefire and were a great help in the early days of the company. They really believed in our business and vision when nobody else did, embracing out value-added Open Source product model when most of the investment community thought it would never work. They also helped us build a great and lasting team at Sourcefire from the initial handful of developers we had hired. Some of the hires from the Series A days are still with the company! I would highly recommend Mark and Tim as trusted partners for any entrepreneur looking to raise capital today."
