Tech248 Director Greg Doyle interviews Mark Hillman, co-founder of MadDog Technology, one of the members of a group that represents 1000 companies. MadDog is in the historic Riker Building in downtown Pontiac, creating a world-class tech space, Hillman said. MadDog incubates and invests in software companies, some eight and counting. Former Compuware co-founder Peter Karmanos is Hillman’s partner – in case you wondered where he went after he left Compuware. MadDog also has raised a venture capital fund.
