The ecosystem

Arthemis: the ecosystem that runs your business

A management system that fits any niche. You switch on only the modules your operation uses and we shape the rules around it. What lives today in spreadsheets, email and three separate systems starts living in one place.

MULTI-TENANT BASE

ARTHEMIS · v1.0 · 2026

/ BOARDS

A real operation running on Arthemis — kanban, subtasks, values and deadlines in one place.

Arthemis — kanban board running a client operation

01

Boards

Kanban, list and threads. Subtasks, custom fields, automations and per-board reports.

02

Calendar

Meetings, rooms and scheduling with public links and Google Calendar sync.

03

Clients

Records, contracts, plans, schedules and activity history per client.

04

Client portal

Your client's own area, in your brand: requests, files, calendar and threads.

05

Roles and permissions

Roles, teams and access granted by module, company or user.

06

Files

Folder trees, S3 upload, signed URLs and public links with expiry.

07

Support

Internal tickets in Kanban and a direct channel to our dev team.

08

Notifications

Real-time stream, per-event preferences and alerts by company or user.

In the same package: intake forms, schedules, reminders, execution plans, releases and audit logs. Commercial proposals and Arthemis Juri are still being built.

Arthemis opens to new operations in batches. Join the list and we'll tell you when your turn comes.

Custom builds

High-end engineering, built around your operation

We develop custom mobile and web applications. We handle the design, the API and the store release.

  • Mobile

    One codebase, two stores. iOS and Android from the same base.

  • Web and dashboards

    Portals and internal panels for the people running the day.

  • API and integrations

    We wire the new system into what already runs in house.

  • Product design

    Flow, interface and prototype before the first line of code.

How we work

A timeline set project by project

We do not sell catalogue deadlines. One cycle, three stages and a date agreed before we start. You follow every week.

STAGE 01

Design

Flows, screens and an approved prototype before any code.

STAGE 02

Build

Code, API and a delivery you can see every two weeks.

STAGE 03

Review

Fixes, testing and release — store, server or domain.

ORDER OF MAGNITUDE

Every project has its own clock

The figures below are orders of magnitude, not a catalogue promise. The date comes out of the scope and into the contract.
