The leaders behind 20 years of growth and success for Planisware.


CEO and Founder of Planisware

Pierre Demonsant is the CEO and Founder of Planisware. Early on in his career at Thales IS, within the information systems subsidiary called Syseca, Pierre recognized the frustration that matrix organizations undergo when attempting to organize complex work spanning multiple work streams.

In 1992, he began to develop project planning software that would be able to support intricate networks of dependencies and constraints across business units and teams. This software would later be adopted by Arianespace and EDF. 

Following his early success, Pierre incorporated a spin-off of Thales called Planisware in 1996, signing multi-national pharmaceutical giant, Sanofi as Planisware’s first client. Today, Planisware serves over 290 organizations across 4 continents. Pierre continues to oversee the company’s strategy and international expansion and sits on the board of several software companies.

Pierre graduated from Ecole Polytechnique in Paris, France, specializing in artificial intelligence and operational research. Pierre has a wife and two kids, and is an avid kite surfer.

With several years of experience as a Planisware consultant in Paris under his belt, Antoine Villata moved to the US in 2001 to establish Planisware Services in North America, starting operations in both California and New Jersey.

Antoine has more than 16 years of hands-on experience in the field of project and portfolio management (PPM). His experience includes designing and implementing PPM solutions at several major NPD companies, directing global multi-site and multi-region projects, and partnering with prestigious consulting firms to implement processes and methodologies that increase returns on R&D investments. He uses his cumulative experience on a daily basis in his role of overseeing operations and supporting Planisware's expansion in North America.

Antoine received an MS in Innovation Management from Compiegne Technology University (UTC) in France as well as an MBA in Marketing and Finance from the Wharton School.

On weekends, Antoine enjoys spending time with his wife and two small children, and kitesurfing around the Bay Area!
