While most maritime companies chase the latest AI navigation tools, Corrosion.nl operates in the shadows—literally. They combat the invisible, unstoppable force that eats $2.5 trillion from the global economy annually: corrosion. With just 96 employees generating $25.4M in revenue, they've built a specialized fortress in one of shipping's most critical niches.

"They don't sell software—they sell survival. Every dollar spent on their corrosion protection is a ship saved from structural failure."

Chelly Jetten, their Sales Maritime lead, represents the human engine behind this machine. In an industry built on decades-long relationships and technical trust, a single salesperson can manage relationships worth millions. The 96 employees likely include naval architects, materials engineers, and project managers who don't just sell products—they design entire protection systems for vessels that will spend 30 years at sea.

• Revenue per employee: ~$264K—exceptional for a technical services firm
• Traffic-to-revenue ratio reveals a high-ticket, low-volume sales model
• No detectable tech stack suggests heavy reliance on traditional engineering tools and direct client relationships
• Top traffic countries are undefined in data, suggesting a truly global but fragmented client base
