YesWeHack is a cybersecurity company that was founded in 2015. The company has developed a platform to
manage Bug Bounties, a cybersecurity technique consisting in incentivizing a community of ethical hackers to
detect and report vulnerabilities in exchange for bounties. YesWeHack connects organisations to tens of
thousands of ethical hackers. The goal is uncovering and patching vulnerabilities in websites, mobile apps,
connected devices and digital infrastructure. YesWeHack has a strong international footprint with dominant
positions in France and Singapore and clients coming from over 50 countries.

Hundreds of organisations worldwide – private, public and governmental – already benefit from YesWeHack’s
in-house triage3, personalised support, customisable model and a results-based billing model for the customer.
Built and run by ethical hackers, YesWeHack has in-depth knowledge of what ethical hackers and
organisations need from a Bug Bounty platform to cost-effectively secure digital assets, reputations and
customer data.

Antoine Izsak, Head of Growth Equity, said:
« Bug bounty is now recognised as a must by some of the companies most exposed to the cyber threat. We
are delighted to be working with the European leader YesWeHack, which stands out for its quality of service,
compliance with regulations and the relevance of its technological roadmap for customers who are increasingly
overwhelmed by the growing volume of vulnerabilities.»

Guillaume Vassault-Houlière, YesWeHack CEO, stated:
« This new round of funding is a vote of confidence in our commitment to excellence and ambitious vision.
Thanks to this investment, YesWeHack commits to delivering even higher levels of customer satisfaction and
accelerating development of innovative solutions in one of the most dynamic market segments in
cybersecurity. We would like to express our deep gratitude to Wendel for their support. Their considerable
experience and long-term vision will be decisive assets for YesWeHack in this new phase of its development,
which will make it a global player in cybersecurity.”
