Personio: In September, media reports revealed that Personio was renting space in a new office complex in Munich's Bahnhofsviertel district. In terms of contract value, this was said to be the largest lease in Munich's history at the time. The company was paying just under €50 per square meter per month, reported the Süddeutsche Zeitung. Over the 15-year contract term, this would amount to approximately €350 million in rental costs for the Munich-based unicorn. Personio was founded in 2015 by Hanno Renner, Roman Schumacher, Arseniy Vershinin, and Ignaz Forstmeier. The Munich-based startup offers HR software for small and medium-sized businesses.
