About

OSOI, One Source of Information, is a mobile-first work management platform for companies that coordinate people, tasks, communication, documents, planning, and time-related workflows across the field and the office . Instead of spreading work across chats, spreadsheets, shared folders, emails, calendars, and separate operational tools, OSOI brings everything into one connected system .

It is built for operational teams that need speed, clarity, and real adoption in daily work. That includes construction, architecture, engineering, facility management, maintenance, service operations, and other businesses where work does not happen only at a desk. OSOI is designed from the phone outward , so it works naturally for people on site while still giving office teams the structure and visibility they need.

At its core, OSOI connects communication and execution . Teams can communicate directly, collaborate in groups, work in project and task context, manage documents and notes where the work happens, track time and absences, plan resources, and search knowledge across the company.

OSOI’s ambition is not to become one more project management tool. It aims to become the command center for teamwork in operational companies, a single environment where work is discussed, documented, planned, executed, searched, and improved.

Let's build better, together.
