What is Builders of X?
Builders of X is the #1 intelligence database for discovering real, revenue-verified software businesses, SaaS apps, and digital products built by solo founders and tiny teams. Instead of guessing what to build next or scrolling through unverified hype, you get actionable business blueprints: every listing breaks down what the product does, how much monthly recurring revenue ($MRR) it makes, the tech stack behind it, and how the founder acquired their paying users.
Our database is updated automatically every single day with 50+ proven business ideas sourced and cross-verified from Stripe-verified leaderboards, founder interviews, and live revenue directories. Plus, through our Global Builder Network, you can still discover the actual makers behind the products, connect with indie founders by city or country, and submit your own high-MRR product to get featured in front of thousands of builders, buyers, and investors.
Who it's for. Solo founders, indie hackers, vibe coders, micro-SaaS builders, developers, and small teams looking for their next profitable, already-validated business idea — as well as founders who want to showcase their verified MRR and drive high-intent traffic to their products.
Who builds it. Builders of X is built and maintained by Orbit28, an independent product studio dedicated to helping solo builders and small teams ship profitable internet businesses.
