The Story
How we built a complete multi-tenant SaaS platform that rivals Shopify and Wix
"What if I told you I built a complete multi-tenant SaaS platform—with a drag-and-drop site builder, full e-commerce, payment processing, and order fulfillment—in just six weeks?"
Most businesses spend $150,000 to $250,000 and wait 6 to 9 months to build a platform like Shopify or Wix. Traditional development agencies quote six-figure budgets, assemble teams of developers, and deliver months later—if they deliver at all.
We took a different approach. Using AI-assisted development, we built 21st Dev Labs in just 42 days—a fully functional website builder that lets businesses launch professional sites in minutes, sell products online, and manage orders through a complete fulfillment backend.
