Focus

Artificial intelligence

accilium puts AI to work in its own company first and advises on that basis. The internal programme is called project aIQ: every week a new release goes out to the whole firm.

Pioneers
try new tools, filter what works and build on the releases every week.
Ninjas
test what was built and carry it into the whole organisation.

For clients

  • AI governance
  • Enablement of employees
  • Finding and prioritising use cases
  • Delivery: agents, AI programmes, operating models
„AI is never finished in an organisation. It is a capability you have to build, comparable to an operating system of its own.“
David SchneiderbauerAssociate Partner · Energy
