Find proven SaaS opportunities built on YOUR tech stack.
General marketplaces index products by revenue or niche. techtobiz.fyi reverses the index: search verified business case studies by the languages, engines and binaries they are built on — then use the PBN canvas to spot where you can ship something better or new without abandoning the stack you already master.

Every case study is decomposed into three lenses, so you leave with a direction — not just data.
What already works for this product: validated demand, pricing that converts, and the distribution loop behind the revenue. You are not guessing — the market spoke.
Where the incumbent hurts: user complaints, tech debt, memory hogs, missing local-LLM support, platform gaps. Each weakness is an entry point for a stronger build.
Your actionable move: what a founder with this exact stack can ship next — an adjacent product, a modern rewrite, or a niche the incumbent architecture can't reach.
