In a world obsessed with public 5G coverage, Cumucore is betting everything on the opposite: the invisible, private networks that power factories, ports, and mines. With just 12 employees and $2.3M in revenue, this Helsinki-based telecom software company is building the invisible backbone for industrial IoT. Their story isn't about flashy marketing—it's about the quiet, relentless execution required to make private 5G a reality for the world's most demanding industries.

"They're not selling to consumers—they're selling to the CTO of a mining company who needs 99.999% uptime in a 500-meter-deep shaft."

Their tech stack—jQuery, Tailwind CSS, Bootstrap—might seem dated for a cutting-edge telecom company, but it's a deliberate choice. This isn't a consumer app; it's a functional, documentation-heavy site built for engineers who need to access technical specs quickly. The presence of RSS feeds and structured data suggests they're prioritizing SEO for technical documentation over flashy frontend experiences. Their social presence is minimal but strategic: LinkedIn for B2B networking, YouTube for technical demos, and Twitter for industry news.

• They're solving the 'last mile' problem in industrial connectivity—where public networks fail and traditional Ethernet is too rigid
• Their 3GPP compliance is a moat: it means they speak the same language as telecom operators but with enterprise agility
• The 12-person team structure suggests extreme leverage—likely 2-3 core engineers per product line, with the rest in sales and support
