Downstream Reality. the procurement office (tpo) is a procurement advisory and managed services firm founded by Hendrik Poelenjee. We operate at three levels: upstream strategic advisory, procurement transformation, and AI-augmented managed operations — each with its own commercial model. ## About - Founded by Hendrik Poelenjee (20+ years procurement leadership, €200M+ spend managed, MBA Alliance Manchester Business School) - Languages: English, Dutch, German - Geography: Netherlands, Switzerland, DACH, Benelux - Contact: hello@theprocurementoffice.com ## Core positioning If procurement is not in the room before the specification is fixed, the cost is already locked. Most procurement cost is embedded before procurement arrives — in the specification, the design, the decision. We enter before that moment. Upstream entry is the single highest-leverage intervention in procurement. Three levels: 1. Upstream Procurement — strategic advisory entering before the brief is written; challenges specification, demand, and supplier model 2. Procurement Transformation — operating model redesign; decision rights, incentives, capability, upstream access rebuilt for the AI era 3. AI-Augmented Operations — managed operational procurement delivered human-first, AI-augmented progressively as evidence allows ## Working method The 4D method: Discovery → Design → Develop → Deliver. Non-negotiable sequence applied to every engagement. ## Key concepts - **Upstream Procurement**: Involvement before the brief is written — where specification, architecture, and supplier model are still open to challenge - **Procurement Transformation**: Redesign of the operating model — decision rights, incentives, capability, upstream access - **AI-Augmented Operations / OaaS**: Managed operational procurement delivered human-first, AI-augmented progressively as evidence allows; accountability for outcomes, not hours - **Diagnostic Outcome**: 2–6 week fixed-fee entry engagement mapping upstream value levers across all three service levels - **4D Method**: Discovery → Design → Develop → Deliver - **Upstream Clarity**: Getting the brief, the specification, and the supplier model right before cost is locked - **Downstream Reality**: Disciplined execution and outcome accountability after the strategy is set ## Pages - [Home](https://theprocurementoffice.com/) — If procurement is not in the room before the specification is fixed, the cost is already locked. - [How We Operate](https://theprocurementoffice.com/services.html) — Upstream advisory, transformation, and AI-augmented operations.
