For the company you run today—and the one it can become.

Opelli began as an internal system for a company coordinating work across employees, specialists and clients. You can start with three users free, then keep the same connected platform as projects, people and processes multiply. It fits growing SMEs today, with a clear path toward the certifications and enterprise integrations larger organizations require.

Why it exists

The spreadsheet at the end of the month.

A plan in one tool, hours in another, a pipeline in a third, and a person exporting all three into a spreadsheet to find out whether the month worked. Every number is right in its own tool and no two agree, because nothing shares a definition of a project, a person or a month. The problem appears early and becomes more expensive with every new team and process.

Opelli's answer is one platform where projects, time, customers and finance share the same data. The project overview, the month-end invoice and the report for an investor therefore show the same numbers. The assistant you already use can work with the same connected context.

Start with three users free; add paid users as the team grows.
One platform and seventeen modules; use what you need without rebuilding the stack later.
Work across employees, specialists and client guests with one connected context.
Keep data portable and permissions consistent as the organization becomes more complex.

Built to grow

Start lean. Add structure when you need it.

A small team should be able to prove a better way of working without a rollout project. A growing company should not have to migrate again just because the first approach worked.

Start — Three users freeAll seventeen modules are available from the beginning, so a small team can validate the whole workflow before making a larger commitment.
Grow — One connected platformAdd people, projects and client collaboration without splitting the company back across separate tools.
Ahead — A deliberate path upwardCertifications and enterprise integrations extend the size of deployment without changing the connected model underneath.

How we build

Foundations that should not change with company size.

When a company runs core work in one system, its foundations need to hold as the organization grows.

Connected contextProjects, time, customers and finance share one source of truth. People and connected assistants work with the same context.
Progressive adoptionStart with the workflow you need today and add more without moving the company to another platform.
Consistent controlOne permission model applies across the product, including connected assistants.
An open pathOpen formats and the API keep data portable and future options open.

Where we are going

Enterprise is a capability set, not a label.

Today, Opelli is ready for growing SMEs. We do not treat enterprise as a label: larger deployments require independently verified security, enterprise identity and deeper integrations. We are adding those capabilities in stages while keeping the fast start and direct product experience that make Opelli useful to smaller teams.
