This past year I have attended several demo days and covered Launched Box Digital in DC and Dream It Ventures in Philly among others. Yesterday was the demo day for another local incubator, this time it's in Pittsburgh. Yes the "Steel City" has more than just steel these days, as six new start-up companies showed off their stuff as part of the Alpha Lab extensive six-month start-up business incubator program. AlphaLab provides funding, free office space, expert business advisors and services during its biannual program in Pittsburgh. Alpha Lab was created by Innovation Works a seed stage investment firm.
