Starting from strategy, risk and controlling, we currently support organisations especially closely on two topics that pay into resilience beyond short-term efficiency.
AI in controlling, accounting and administration
AI changes not just processes but roles, responsibilities and control structures. We guide the rollout from legal clarification to anchoring it in reporting.

When nature becomes a cost factor
Raw materials, supply chains and sites depend on functioning ecosystems more than most realise. We make these dependencies visible and quantifiable, so they land in day-to-day business – not just in the sustainability report.

The AI Compass: a day that turns uncertainty into a roadmap
Your staff are already using AI, often without a plan or clear rules. In the AI Compass we give your leadership team the full picture in one day: what is possible today, what it costs and where it pays off in your processes.
Advice that fits your situation
No superficial concepts, but decision foundations – developed directly with your leadership team, so your organisation stays decision-ready even as conditions change.
Close collaboration
We listen first and take into account the structure, culture and starting point of your organisation.
Structured strategy
Market position, competition and resources are analysed systematically – for realistic, prioritised options.
Integrated risk
Risks are identified, quantified and assessed not in isolation but within the overall strategic context.
Fact-based
All recommendations rest on robust data. Assumptions are stated explicitly.
We look forward to hearing from you.
A no-obligation first consultation clarifies where we can start.
