One engine, every vertical product runs on it.

EE

Fusapp OÜ, based in Tallinn, Estonia.

AI

AI-native from day one, not bolted on later.

Every product shares the same engineering core — not scattered projects, one company.
who we are

We fuse people, software, and AI.

Every product starts on the same engineering core — shared identity, shared infrastructure, shared discipline — instead of being rebuilt from scratch each time.

the vertical engine
How we build

One engine. Every product moves fast.

Shared foundation

Every product starts on the same engineering core — identity, infrastructure, and discipline already solved.

One market at a time

Each product is built for the workflow of a single market, not stretched to fit every one.

Build, grow, hand off

We take a product to a market position worth owning, then let it stand on its own.

Our products

One engine. Many verticals.

We're a multi-vertical product company, not a single marketplace. MarbleMap and Fusapp Go are live today; more focused products for finance, sales, work management and orchestration workflows run on the same engine.

01

Fusion meets focus.

Every product starts on the same engineering core — shared identity, shared infrastructure, shared discipline — instead of being rebuilt from scratch each time.

Vertical-native, not generic.
