In the shadow of the EV revolution, Rypos is quietly perfecting the art of keeping diesel alive—cleanly. They design active DPF systems that turn legacy diesel assets from environmental liabilities into compliant powerhouses for data centers, hospitals, and logistics giants.

"They don't compete with Tesla; they make the world's diesel engines survive the clean air era."

With a team of 49, Rypos operates at a revenue-per-employee ratio of ~$167k—healthy for a hardware/software hybrid in a regulated industry. Their tech stack (jQuery, Tailwind, Bootstrap) suggests a pragmatic, not bleeding-edge, approach: build what works, ship reliably. The lack of funding data implies they're bootstrapped or have strategic investors who value steady growth over blitzscaling.

• Niche dominance: They own the active DPF space for standby generators and TRU trailers
• Regulatory arbitrage: Their systems are certified for the strictest EPA/CARB standards
• High-intent traffic: Keywords like 'CARB certification' (20 volume) signal serious buyers
• Stable operations: 49 employees, $8.2M revenue, no flashy funding rounds
