COMING UNBOUND? Xconomy reports that Aaron White, one of the three co-founders at Boston-based startup Boundless, has stepped down from his position as Chief Technology Officer. This follows the departure of another co-founder, Brian Balfour, who left his post as Chief Marketing Officer last September. This leaves CEO Ariel Diaz as the only founder left. This is a little shocking even given the fast pace of change in the startup world, and especially given that the company raised an $8 million Series A just a year ago. The company, which offers students free, online textbooks created from open source content, continues to make headlines as it fights an ongoing lawsuit filed by Pearson, Cengage, and Bedford, Freeman & Worth--charges it has ardently defended itself against. One can only wonder if White and Balfour were a little weary of the litigation.
