In a world obsessed with flashy SaaS unicorns, Lighthouse.io is playing a different game entirely. They are quietly powering the backbone of the physical workforce—cleaning and security teams—with a mobile-first management platform that actually generates revenue. While most startups burn cash for growth, Lighthouse is already profitable on a unit basis, turning $2.2M in annual revenue with just $1.3M in total funding.

"Lighthouse.io proves you don't need a billion-dollar valuation to build a sustainable, high-margin business in the trenches of the service economy."

The tech stack reveals a modern, pragmatic approach. They utilize Tailwind CSS and Bootstrap for rapid UI development, ensuring a mobile-responsive experience that works on any device. By leveraging PWA (Progressive Web App) technology and Lazy Loading, they ensure the app performs well even in low-connectivity environments—a critical feature for field teams. They aren't reinventing the wheel; they are using proven tools to build a reliable machine.

• Bootstrapped Efficiency: $2.2M revenue on $1.3M funding suggests a lean, capital-efficient model.
• Niche Dominance: Owning the 'cleaning & security' vertical allows for deep feature specialization.
• Organic SEO Engine: Nearly half their traffic comes from search, indicating strong content and product-market fit.
• Mobile-First DNA: The tech stack (PWA, Lazy Loading) is built specifically for field operations.
