Łukasz Ostrowski
Founder, RITAN
I spent two decades in procurement — strategic sourcing, supplier management, category strategy, M&A integration. Most of it inside organisations where procurement was either a cost centre fighting for relevance or, on the better days, a strategic function shaping how the company spent its money.
Since 2024 I work full time on what I now call AI Procurement Operating Model. The original problem was simple: procurement teams across Europe were experimenting with ChatGPT in private, without governance, without method, without a way to make those experiments stick. After eighteen months of working on this with clients in Poland and DACH, the pattern became clear enough to package as a methodology — PAIR Assessment as entry, seven layers as the system.
I'm based in Warsaw through Ritan Sp. z o.o. and work primarily across Poland, Germany, Austria and Switzerland.
I don't run a generic AI consulting practice. RITAN does AI Procurement Operating Model — that is the product, that is the engagement. No adjacent service lines, no partnership commissions, no sprawl into "we also do data warehousing".
The reason is practical. Procurement AI is specific enough that doing it well requires real procurement experience plus deep familiarity with how current AI tools actually behave on real procurement data. A boutique focused on one methodology delivers that. A 200-person AI consultancy with a procurement practice usually does not.
For implementation work that goes beyond what I can deliver personally, I bring in a small network of vetted senior practitioners — always with me as the single point of accountability. You get one person to talk to, one person responsible for the outcome.
We talk about your procurement context, what you've tried with AI so far, and whether PAIR Assessment is the right next step. No commitment from either side.
