Fusapp OÜ is built around one thesis: fuse people, software, and AI into a single engineering core, then use that core to stand up, grow, and — when it's the right call — hand off focused vertical SaaS products. We're not a platform stretched to serve every market. We're an engine for building the ones we understand best, one at a time.
Every product starts on the same engineering foundation — shared identity, shared infrastructure, shared discipline — instead of being rebuilt from scratch each time.
Each product is built for one market's real workflow, not stretched thin as a generic tool trying to fit every industry at once.
We take a product from first release to a market position worth owning — and once it earns its own focus, we let it stand on its own.
We don't name every product here — some are still finding their market. What we can say is where the engine is pointed.
Cash flow and cost tracking for small and mid-size businesses.
B2B marketplaces built for one sector at a time — our first live example is MarbleMap, for natural stone.
Tools for running the day-to-day of a growing operation — tasks, teams, and workflow.
The AI and automation layer that coordinates the rest — behind the scenes, not the pitch.
Every vertical starts on the same engineering core. Once a product proves its market, it earns its own focus — a dedicated team, its own roadmap, sometimes its own company. The engine's job is to make that possible, not to hold every product forever.
