Dec 2017SecondaryVitruvian Partners (lead)$180M$600MBitdefender is a Romanian-based global cybersecurity company providing end-to-end security solutions and advanced threat protection to over 500 million users in more than 150 countries, serving consumers, enterprises, SMEs, and governments. The company employs over 1,300 staff across nine offices, with its enterprise solutions headquarters in Santa Clara, California, where more than 40% of sales are generated from the US market. In December 2017, Vitruvian Partners acquired approximately a 30% minority stake in Bitdefender from existing shareholder Axxess Capital in a secondary transaction, valuing the company at over $600 million. Vitruvian became the second-largest shareholder after co-founders Florin and Mariuca Talpes, who retained majority ownership, with a group of private investors holding the remaining minority stake. The deal, advised by Deutsche Bank and pending regulatory approval, involved a transaction value of $180 million but did not inject new capital into the company. Bitdefender had demonstrated rapid growth, particularly in international operations and enterprise solutions, enabling expansion of its product portfolio while maintaining a sound financial footing. The investment aligned with Vitruvian's strategy of supporting high-growth technology companies undergoing scaling and transition.
