While Silicon Valley chases the next AI unicorn, VitalSource quietly dominates the infrastructure of digital education. This isn't a flashy startup—it's a $74M revenue engine delivering learning to millions, proving that boring infrastructure beats hype every time.

"VitalSource isn't selling content—they're selling the invisible infrastructure that makes digital learning actually work at scale."

The tech stack reveals their focus: jQuery, Bootstrap, Tailwind CSS—battle-tested workhorses over bleeding-edge frameworks. They're not building for tech bloggers; they're building for stability at enterprise scale. Vite for builds, Google Analytics for measurement, Lazy Loading for performance—this is a team optimizing for delivery, not vanity metrics.
