Don't Nod Entertainment SA is a French video game developer and publisher based in Paris. Founded in June 2008, it started development on Remember Me (2013). Because of its poor return on investment, Don't Nod entered "judicial reorganisation" in 2013. With the help of French agency funding, it developed Life Is Strange, whose successful release raised Don't Nod's industry status. It began third-party publishing with Gerda: A Flame in Winter in 2022.
