What happens in many ensembles
Three problems Weikos leaves behind
The sheet music doesn’t arrive on time
With Weikos: Each score goes straight to its musician, on their phone, and is removed automatically when the project ends.
The schedule changes and nobody is told
With Weikos: You publish the change and every musician gets a notification and sees it in their calendar.
Announcements get lost
With Weikos: They reach the people they’re meant for, and you know who has read them.
How it works
From planning to the stage, and everything after
The management team works on the web; each musician, on their phone. Both see the same thing, instantly.
- 01
Plan your projects
Each project with its programme, instrumentation and schedule: rehearsals, performances and venues, without spreadsheets. You publish the roster once it’s decided.


- 02
Hire without chasing anyone
The musician gets the offer on their phone, fills in their details and the requirements, and accepts. You always see who and what is still missing.


- 03
Call and rehearse
Every change reaches each musician’s calendar, with venue, times and documents. No lost emails or messaging groups.


- 04
Perform with everything in order
Musicians have their next service at hand and clock in and out from their phone or with their card in Apple Wallet or Google Wallet.


- 05
Close the accounts
Budget against actual spending on every project, invoices that read themselves and SEPA batch payments.

Who’s behind it
Weikos was born from more than twenty years in orchestras and cultural projects, and it has been built by professionals in management, production, finance, music libraries and performance.
And it gets better every day thanks to the people who use it: every technician, every librarian and every musician in the ensembles that work with Weikos. What we learned solving these problems is already built into Weikos.
Frequently asked questions
What people usually ask us
How long does it take to start using Weikos?
Very little. To begin, we do the initial set-up with you (the organisation, the ensembles and the roles), which takes less than an hour. From then on you can create projects and the musicians see them in the app. If you start with one or a few projects, you’re up and running the same day. With a whole season, it usually takes a week to have everything in place. We run as many training sessions as you need with your management team, plus one session to introduce the app to the musicians.
Will you help us move what we already have into Weikos?
Yes. Send us the list of your permanent members and staff, in whatever form you have it, and we’ll get their contracts ready. Each musician creates their account and we link it to their contract. Many musicians are already on Weikos, so this is usually immediate. If you want to start with some history, we’ll help you load your latest projects, as well as the season’s planning or budgets. Everything else (projects, services, sheet music) you add yourselves from day one, and if anything gets complicated, we’ll lend you a hand.
How much does it cost?
It’s an annual subscription, priced according to the size of your organisation. We prepare a tailored proposal for you after the demo. It includes onboarding, training, the apps for all your musicians and support, with no per-musician cost.
How do you protect our organisation’s data?
Your musicians’ and your organisation’s data is protected in several layers:
- Where it is: on Amazon Web Services, in Frankfurt, within the European Union, and always stored encrypted.
- The most sensitive data, doubly protected: ID documents, IBANs and other sensitive personal data also have their own encryption, field by field.
- Everyone sees what they need: each person can only access what their role allows, and even then sensitive data is hidden on screen from anyone who doesn’t need to see it in full.
- Everything leaves a trail: we record who changes, exports or deletes each piece of data, so you always know what happened and who did it.
- And in writing: the data processing clauses required by the GDPR are part of the contract with every organisation.
What support do we get?
Write to us at help@weikos.io and we’ll reply on working days. If something is stopping you from working, we deal with it as a priority, and other queries usually the same day. Support is for everyone, the management team and every musician, and it’s included in the subscription, as are maintenance, updates and backups. An AI assistant helps us, and there’s always a person from the team behind it. At help.weikos.io you’ll find step-by-step guides to every part of Weikos, and for onboarding we support you with online training sessions.
We’ll show you Weikos with your own projects
