The story
Planisware was founded in 1996 by Matthieu Delille, Pierre Demonsant, Yves Humblot, and François Pelissolo. The founding team was from Thales Group, a French aerospace and defence corporation.
Around May 2023 Planisware started working with investment bankers to explore a potential initial public offering (IPO). At that time, the private equity group Ardian held a stake in the company. In October 2023, Planisware announced plans for an IPO on Euronext Paris at a valuation of between 1.11 billion and 1.25 billion euros, then decided to postpone the IPO due to a "deteriorated" market environment. The IPO launched in April 2024 at a valuation of 1.11 billion euros. The founders retained a majority stake in the company. In September 2024, Ardian announced plans to sell their remaining shares in the company.
