An independent company with a long history of innovation
Decisions here are made by the people who build, which is why we can move fast, experiment, and redefine what we ship without waiting on anyone. We invest in software products that keep improving year after year, and the portfolio has grown every one of them.
Product-first
We build and own our platforms rather than chasing one-off client projects, so every release makes our products better.
Always reinventing
Innovation is a habit. We have spent years refining our craft, adopting new technology and reinventing ourselves around what customers need.
Trust at the core
Data quality, transparency and long-term value guide every decision. We build software people can rely on.
A full business suite, and the platforms around it
Rutba Suite, the next generation of our ERP as SaaS, with business, workspace and platform products on one backend; Rutba Office, a free desktop suite on our own document engine; and Paritas, an Oracle-compatible PostgreSQL. Around them sit the AI surveillance and procurement platforms, a live shop, and the media and email infrastructure that carries it all. Much of it ran our own operations before anyone else's.
Rutba Suite One account
The next generation of our ERP, rebuilt as SaaS on a new engine and grown well past it: CRM, marketing, commerce, inventory, orders, manufacturing, facilities, fleet, people and books, a workspace of mail, docs and sheets, e-signature and chat, and the platform services underneath. Meetings, calls and a file drive are coming. Sold on rutba.io.
