“We know your business, we calculate the benefit, and we deliver it together with you.”
Rinascai is the AI business partner for organisations that want to stop debating artificial intelligence and put it into production instead.

What we hear from decision-makers
I don’t yet know exactly what I need.
I don’t know what it costs or what it returns.
My pilot projects aren’t paying off.
There is no shortage of strategy papers. What is missing is someone who implements them.

The six services
From clarity to operation,
accompanied by the AI Officer.
The diagnostic is the first of five stages. Each has its own trigger — you start where your organisation stands today.
01
Clarity
Your target picture reflected back, use cases assessed, legal position established — evidenced, not assumed.
Enquire06AI Officer as a ServiceAccompanies the process as a business and technical sparring partner and takes care of governance and project management.
Free entry point
Where does your organisation stand on AI?
In four weeks you have the basis to decide.
Clarity is the first of the five stages: four weeks, free of charge. Together with executive management, IT and your internal AI champions we produce a clear diagnosis — evidenced, not assumed: where the opportunities are, where the risks are and which next steps make sense.
- Your target picture reflected back: what you want from AI and what of it holds
- Assessed use cases with quick-win and scaling potential
- Legal position under the EU AI Act, GDPR and internal governance requirements
- Recommendation for target architecture, operating model and the AI Officer role
- Concrete next steps including effort, responsibilities and roadmap
From more than 1,000 identified use cases we know where AI creates impact in organisations — and where it initially just creates work.

We build AI that works.
Secure, integrated, scalable.
Lay the foundation
Processes, data and target picture first — then models, agents and automation. We apply AI where value, feasibility and controllability come together.
Governance by design
The EU AI Act, GDPR, roles, audit trails and documentation are built in from day one. That reduces liability, compliance and operational risk and creates the basis for scaling AI.
Enterprise-ready, Mittelstand-minded
We combine pragmatic delivery with enterprise standards: transparent budgets, fast decisions, secure architecture and delivery by certified AI Officers.
Bring people along
AI changes how people work. That is why our highly experienced managers support your leadership, business units and IT with change management, AI literacy and new role models — so that humans and agents work together productively.
The people behind Rinascai
Management Team.
As external, certified AI Officers and with an EU AI Act compliant software suite, we work inside mid-sized and large organisations across the DACH region — from diagnostic to production operation.
We grew out of the operating and data analytics practice of OPCORE Partners. Our strength is the combination of strategy, process understanding, a technology product and operational delivery including change support. We are neither a pure strategy consultancy nor a pure tool vendor: we build for you, or with you, the systems that make AI effective and governance-compliant in your organisation.
Sebastian DahmCo-CEO
AI becomes valuable when it improves a company's operating model — not just when it extends the tool landscape.
References and career stations
Experience that
companies trust.
For over a decade the Rinascai team has worked for and supported retail and industrial companies — from family businesses to global groups, from strategy and operating model to data-driven process automation.
These seasoned consultants made a decisive contribution to realigning our cross-category purchasing strategy. What impressed me most was the combination of deep subject-matter expertise, a strong understanding of sports retail and data-driven solutions. The tools and methods they introduced remain in use far beyond the project and provide valuable impetus for developing our organisation further. The project result speaks for itself and creates lasting value for our company.
During my time as Chief Merchandising Officer at SportScheck, these experienced experts guided me through numerous strategic challenges. From analysing and preparing supplier negotiations to developing our category management further, we were consistently supported with hands-on expertise, a structured approach and a clear focus on results. Their consulting approach is rigorously client-centred and aimed at tangible impact and lasting implementation by the operational teams.
Working with the team allows us to develop practical, AI-supported solutions for retail that create real impact. Together we are shaping the digital transformation of retail and wholesale with tailored approaches.
On the ground
Present across
the DACH region.
We work where our clients decide and deliver: in person with management, close to the business units and compatible with IT teams. Operationally led from Karlsruhe and Zurich, with contacts in the key DACH locations. You get one regional, personal contact — for the first conversation, the diagnostic and the delivery.
