The online platform for museum operations

Run your museum,
finally off
the spreadsheet.

The work of running a museum deserves a dedicated home — structured, shared by the whole team, and alive between board meetings.

Alternexium is the online platform where everything your museum runs on lives in one place — visitors, projects, teams, KPIs, the strategic plan. Open it in any browser. The whole team works from the same view, month after month.

For directors of Museums
Built on The Alteradvise method
Available in French & English
What we noticed 01 — 03
Spreadsheets weren't designed to be the place where a whole museum lives.

It stays static.

Once approved, the plan is hard to keep alive. A spreadsheet doesn't invite anyone back in between cycles.

It speaks in one voice.

Curators, educators, board members, audiences — none of them naturally edit a director's spreadsheet. The plurality of perspectives gets lost.

Strategy sits apart from operations.

KPIs in one file, programming in another, audience data somewhere else again. The links between intent and reality have to be reconstructed by hand.

Comparison is hard to come by.

Are your targets ambitious? Realistic for an institution of your scale? A standalone file can't tell you — and the sector lacks a shared benchmark.

The instrument 02 — 03
Five modules. One online platform, opened in any browser. Designed to be opened on a Monday morning, not once a strategic cycle.

People & Working Groups

The connective tissue. Departments and teams in a hierarchical chart, plus a parallel layer of working groups — temporary, cross-departmental, formed for a project and dissolved when the work is done. Every KPI, objective, and project links back here.

  • Departments & teams hierarchical
  • Working groups temporary
  • Internal staff & stakeholders unified
  • Linked to KPIs & projects structural

Questions we hear a lot.

When does the product actually launch?+
The free year runs from 1 January 2027 to 31 December 2027 for every founding member, regardless of when within the year they're admitted. The first invoice goes out on 1 January 2028 at $299 for the second year.
What happens after the first free year?+
For year two, founding members continue at $299 per year, billed annually. From year three onward, pricing is tiered by institutional size and applies to all customers, founding members included. Current indicative pricing: Small (up to 5 staff) at $149/year, mid-size (6–25 staff) at $299/year, large (26+ staff) at $599/year — finalised closer to year three, based on what we learn from the founding cohort. If you decide not to continue at any point, your data exports to CSV and PDF and your subscription ends — no notice period, no penalty.
Where is our data stored?+
European Union, on Supabase infrastructure (Frankfurt). GDPR-compliant by design, with row-level security so each institution's data is isolated. Full DPA available on request.
Can we export our data?+
Yes — at any time, in formats that work everywhere. Every list, table, and dataset in Alternexium exports to CSV (Excel-compatible) and PDF: KPI history, project lists, the strategic canvas, the people register. There is no premium tier behind the export button, no rate limit, no proprietary format. If you ever decide to leave, you take everything you put in.
How does the referral discount work?+
Each founding member receives a personal referral code on admission. The code is unlimited — you can share it with as many museums as you'd like, and every one of them takes 50% off their second year ($149.50 instead of $299) once admitted to the programme. On your own side, bringing at least one museum in unlocks 50% off your second year as well. That referrer discount doesn't stack: whether you bring in one museum or ten, your year-two stays at 50% off. The aim is for the founding cohort to grow through the people who already trust each other, not through a generic affiliate scheme.
Is the interface in French?+
French and English from day one. Other languages will follow. Every translatable field — mission, vision, KPI names — supports multiple languages simultaneously, so a bilingual board can read the strategy in either tongue.
What if we don't have technical staff?+
You don't need any. Onboarding takes one ninety-minute session with a member of the team. The product is designed for directors and chiefs of staff, not IT departments.
