Last Thursday, Tucows announced that it was buying Boulder’s NetIdentity. At a deal value of over $20m, it’s healthy for a company with only 10 employees, although my understanding is that NetIdentity was very profitable. Four other Boulder software companies have been bought in the past few months – @Last (Google), Vexcel (Microsoft), Wall Street on Demand (Goldman Sachs), and Micro Analysis & Design (Alion). I sense opportunities for luxury goods retailers in the Boulder County area.
