While global edtech giants chase the SaaS gold rush, a Spanish academy is quietly building a €6.8M empire by dominating a single, hyper-local niche: public sector exam prep for the Galician government. This is the story of Postal3, a masterclass in vertical depth over horizontal breadth.

"They don't need millions of visitors; they need thousands of highly motivated, local candidates ready to pay for a guaranteed path to a government job."

The tech stack tells a story of pragmatic efficiency. They use jQuery and Bootstrap—technologies often dismissed by Silicon Valley elites—but they work. There's no flashy, expensive custom platform here; they use a standard Moodle-based login (oposiciones.tucampusonline.com) and a Tailwind CSS frontend. This isn't a tech-first company; it's a content-first company that uses technology as a utility, not a differentiator.

• Revenue per Employee: ~€144,680 (highly efficient for an education business)
• Social Proof: Active on TikTok, YouTube, Instagram, and Facebook, meeting students where they are.
• Niche Dominance: Owns the 'academia oposiciones vigo' and 'academia postal 3' search categories.
• Direct Traffic Moat: 48% direct traffic creates a defensible brand position competitors can't easily replicate with ads.
