SAN FRANCISCO -- November 11, 2015 -- HackerOne, the leading vulnerability coordination and bug bounty platform provider, today announced the appointment of Marten Mickos as CEO. Mickos is recognized for building some of the technology industry’s most disruptive, community-powered businesses, including MySQL, the second largest open source company in the world. With extensive experience scaling early-stage companies and investing in distributed global workforces, Mickos is well suited to lead HackerOne, the world’s largest hacker-powered marketplace for software vulnerabilities.

“Finding and eradicating software vulnerabilities to make the connected world safer is one of the most pressing challenges of our time and vital for the advancement of our society,” said Mickos. “I was immediately attracted to HackerOne because it brings a new model to security where the best minds in the world can collaborate to solve the most urgent security challenges. The HackerOne approach is ingenious and beautifully aligns the interests of responsible enterprises and responsible hackers.”

HackerOne has helped more than 350 customers fix over 14,000 security vulnerabilities and reward more than 2,000 successful hackers nearly $5 million. With top customers including Twitter, Adobe, Snapchat, Yahoo!, Dropbox, Square, Slack, Airbnb and Vimeo, HackerOne has quadrupled its number of customers year-over-year. In the past four months alone, over 100 new companies have joined HackerOne to improve their security, including Imgur, Hired, Coursera, Zendesk and Marktplaats.

Most recently, Mickos served as the Senior Vice President and General Manager of HP’s cloud businesses after it acquired Eucalyptus, the leading open source software solution to build private and hybrid clouds, where he was CEO. Before that, Mickos served as CEO at MySQL, the world's most popular open source database solution, which was acquired by Sun Microsystems in 2008. He also served on the board of directors at Nokia from 2012 to 2015, and was an Entrepreneur in Residence at Benchmark and Index Ventures.

"Marten is a world-class entrepreneur and we look forward to working with him again," said Bill Gurley, General Partner at Benchmark, who backed Marten previously as the CEO of MySQL. "HackerOne and Marten were made for each other - it’s a disruptive company that is creating a marketplace for great change. Marten’s experience building communities is unmatched, and he is the best person to lead HackerOne on its mission to change how the world approaches security."

HackerOne has raised $34 million from Benchmark and New Enterprise Associates, as well as notable individuals including Salesforce Chairman and CEO Marc Benioff, Digital Sky Technologies Founder Yuri Milner, Dropbox CEO and Co-Founder Drew Houston, Yelp CEO and Co-Founder Jeremy Stoppelman, Zenefits COO David Sacks and and Berggruen Holdings Chairman Nicolas Berggruen, among others.

“HackerOne grew beyond our wildest expectations, putting us in the enviable position to recruit Marten, who has a successful track record scaling world-class organizations,” said Merijn Terheggen, HackerOne Co-Founder. “Similar to what Marten created at MySQL and Eucalyptus, HackerOne is creating an open ecosystem built on integrity, responsibility and transparency, and we couldn’t be more thrilled to have him join HackerOne.”

HackerOne’s founding CEO, Merijn Terheggen initiated the search for a new CEO, as the company entered a new phase of growth. Terheggen will focus on supporting customers, building partnerships and supporting day-to-day operations.
