Paladin Capital Board Executive Joins HTB to Accelerate Global Enterprise Growth and Operational Scale

Hack The Box (HTB), a global leader in gamified cybersecurity readiness and upskilling software solutions, today announced the appointment of Gibb Witham as President and Chief Financial Officer. Witham joins HTB from Paladin Capital Group, a prominent cybersecurity-focused investment firm and early investor in HTB. With total funding exceeding $66 million, HTB is accelerating its mission to empower cybersecurity professionals and enterprises worldwide.

Witham brings two decades of experience at the intersection of finance, strategy and cybersecurity innovation, and now leads HTB’s global financial operations and growth strategy. His appointment comes at a transformative time for HTB, following the strategic acquisition of LetsDefend and the launch of Threat Range, two major initiatives expanding HTB’s capabilities in adversary emulation and cyber defense readiness. These moves reinforce HTB’s position as the trusted enterprise partner for resilience validation, breach risk mitigation and large-scale cyber talent development.

“Gibb brings the rare combination of financial acumen, strategic insight and a deep technical understanding of the cybersecurity landscape,” said Haris Pylarinos, Founder and CEO at Hack The Box. “His leadership will be pivotal as we expand globally and accelerate our mission to build and empower the world’s cybersecurity workforce.”

At Paladin, Witham led investments in high-growth cybersecurity, AI and enterprise infrastructure software companies across the US and Europe and worked closely with HTB’s executive team on its Board of Directors.

“Hack The Box has redefined how cybersecurity readiness is developed, validated and scaled across the world,” said Witham. “I’ve seen firsthand the power of this platform, and I’m excited to join Haris and the team at such an important moment and accelerate the next chapter of growth, particularly as AI radically changes both the threat landscape and how security professionals are upskilled, enabling organizations to get ahead of threats instead of constantly chasing them.”

Witham’s appointment follows a series of strategic executive hires and promotions aimed at strengthening HTB’s leadership bench. Earlier this year, Nikos Maroulis was appointed Vice President of AI, Christine Bartlett joined the company as Senior Vice President of Marketing and Gerasimos Marketos was promoted to Chief Product Officer.

HTB now serves a global community of more than 4 million cybersecurity professionals, students and enterprises. Its platform combines gamified labs, role-based academies, Capture The Flag (CTF) competitions, advanced certifications and AI-enhanced upskilling modules to equip the world with the skills needed to meet the evolving cyber threat landscape.
