In this episode of Cyber Security District, we sit down with Niek Waarbroek (Founder & CTO) and Tycho Klessens (CEO) of Florbs, a Dutch startup transforming file security inside Google Workspace. What started as a simple set of admin scripts has evolved into a powerful SaaS platform, used by global enterprises to automate onboarding, offboarding, and prevent accidental (or malicious) data leaks.

Niek shares how his frustrations with error-prone onboarding flows inspired him to build smarter tools, and how a lack of visibility into shared files became a real security threat for many organizations. After bootstrapping Florbs for three years, he crossed paths with Tycho, then a VC investor, who not only became the commercial co-founder, but helped raise €1 million to scale the team.

Together, they discuss the power of building with product-led growth, how they’re scaling without wasting capital, and why real file security goes beyond Google’s default settings. They also explain why early-stage cybersecurity startups need more than funding, including focus, clarity, and the right partner chemistry.

In this episode, we cover:

• The original problem Florbs set out to solve inside Google Workspace
• Why offboarding is one of the biggest overlooked security gaps
• How ex-employees still access company data without detection
• From custom scripts to a full-fledged SaaS product
• Product-led growth without a sales team or marketing budget
• Raising €1 million from angel investors and CISOs
• Going from solo founder to building a complementary co-founder team
• How they’re building safe, reversible file actions with real-time insights
• Expanding into AI-powered detection and cross-platform collaboration security
• Lessons learned transitioning from VC investor to cybersecurity CEO

Whether you're a CISO, founder, or operator working in Google Workspace or building a startup yourself, this episode shows how automation and visibility can finally close one of the biggest blind spots in modern file security.
