Since 2016, Dullea has led operations for MassChallenge’s eight accelerators worldwide, and has overseen the organization’s financial planning and talent development functions.

“Throughout my career, I’ve seen the transformative power a community can have when it comes together to support entrepreneurs,” said Dullea. “MassChallenge has been a leader in strengthening the global innovation ecosystem by supporting the highest potential startups, and I am honored to take the reins of such a community-driven organization. I am confident that by working together, we can help entrepreneurs reach their full potential.”

“Along with the rest of MassChallenge’s Board of Directors, I am confident that Siobhan is the right leader to take MassChallenge into the future,” said Len Schlesinger, MassChallenge Board of Directors. “From her experience successfully leading MassChallenge’s operations to her passion for entrepreneurs and ecosystem building, Siobhan is primed to help MassChallenge grow its support for startups around the world.”

“I have worked with Siobhan Dullea for over 20 years and have watched her have tremendous impact wherever she goes,” said Diane Hessan, MassChallenge Board of Directors. “She is an outstanding leader who was critical to our ability to scale C Space globally, and, as she takes the reins at MassChallenge, I am confident she will take the organization to a new and exciting level.”

“Siobhan is exactly the right leader to build on the success of the first ten years of MassChallenge,” said John Harthorne, MassChallenge Founder. “Having worked directly with Siobhan over the last three years, I have great confidence in her leadership abilities, and I am extremely excited about the future of MassChallenge under her leadership.”

In her role as CEO, Dullea will be focused on setting and managing strategy for the largest zero-equity startup accelerator in the world.
