Why we bet our fee on your savings.
Founder Wouter Stegenga on Outcome-as-a-Service economics, the Sourcing Twin, and how an OptiProq engagement grows into a self-deployable capability inside your own procurement organisation.
The Problem: Drinking from a Firehose
Jeroen van 't Hert
Wouter, you often say that the procurement world is overwhelmed by tech. How do you see the current landscape?
Wouter Stegenga
It is a paradox. The pace of new tech is overwhelming. Leaders cannot afford to miss the next wave, but it feels like drinking from a firehose. Europe spends €15bn a year on procurement software and the senior bandwidth to operate it, and AI is quietly making most of that spend obsolete.
Jeroen van 't Hert
You've identified "Wave 1" and "Wave 2" of Sourcing Optimization. Why do you believe they are failing?
Wouter Stegenga
Because of a trade-off neither wave resolved. Wave 1 unlocked combinatorial sourcing optimisation, then locked it inside ERP modules that needed a 'Procurement Excellence' team to operate. Wave 2 went the other way: simple SaaS, clean UI, methodology cost passed to the client. That gave us the Tool versus Talent gap. The company bought the Ferrari; the driver never arrived. Either way, the licence sits there, paid for, running events that do not need it.
The Solution: Wave 3 and "OaaS"
Jeroen van 't Hert
So how is OptiProq different from what the buyer can already licence from Coupa or Keelvar or Jaggaer?
Wouter Stegenga
We are Wave 3. We don't sell SaaS licences; we sell outcomes. Under Outcome-as-a-Service, OptiProq carries the platform, the hard-coded methodology library customised per engagement, the constraint model, and the Senior SME orchestration. The client pays from the value delivered. We have skin in the game; we anchor our fees to the business case. If we don't find the value, we don't win. It is the part of the model legacy vendors cannot replicate without killing their own P&L.
Jeroen van 't Hert
You talk about "hardcoding" strategy. What does that look like in practice?
Wouter Stegenga
Most platforms give you a fixed set of toggles and ask you to fit your strategy to them. We do the opposite. The constraint model carries the shades of grey: TCO components below the unit price, supply security, carbon reduction, payment-term cost, working capital, switching cost. We hard-code the methodology that scales, and we customise it event by event to your corporate identity, the commodity characteristics, the strategy, and the stakeholder and supplier voice. We do not impose our tools on your supplier base. Corporates run with one face to the market, and that face should be yours.
The Future: From Buyers to Architects
Jeroen van 't Hert
Where do AI and "Agents" fit into this vision?
Wouter Stegenga
AI is moving us from automating transactional work (PO processing, invoice matching) to augmenting strategic work. The platform executes; the senior SME orchestrates and decides. That shifts the role of the procurement professional from buyer to Category Lead, somebody who designs supply networks, stress-tests them, and signs the award. The Sourcing Twin is the layer that makes it operational. In our SME Collaboration engagements, the Twin is the Senior SME's working assistant and is being trained on the Category Lead's reasoning, event by event.
Jeroen van 't Hert
How does this help companies deal with today's volatility?
Wouter Stegenga
Volatility is the new normal. In the old world, a senior analyst built five Excel scenarios in a week and called it analysis. A single tariff shock today needs a hundred, run against the constraint model the same afternoon. OptiSource runs them in an hour. The Category Lead sees what each scenario costs in cash, in resilience, in lead time. And this is where the Twin earns its keep at scale. We grow the Twin into your organisation event by event, on your specific context, your guardrails, your decision models. Within months, your team self-deploys it. That is what allows us to scale and, more importantly, what every Category Lead in the room actually wants: a capability their own organisation can run.
The Origin Moment
Jeroen van 't Hert
You've worked inside large procurement teams. What's the moment you realised the existing software stack was the problem, not the solution?
Wouter Stegenga
Specific category, specific event. The platform's UI accepted line items and rejected the structural offer the supplier wanted to make. The supplier eventually walked, the buyer accepted a deal that looked clean but left value on the table everyone in the room could feel, and the audit trail showed the platform did exactly what it was designed to do. The realisation was that the software was solving the wrong problem. It treated suppliers as raw material to be sorted, and it left structural offers and package conditions in the gap between what a line-item template can capture and what a senior buyer actually negotiates. What we built is the opposite. Procurement is about security of supply, leveraging your supply base, innovation, and synergies between suppliers nobody at the table has seen yet. The literal commitment is this: each participating supplier wins, and the buyer wins most. Every supplier brings their structural offer and package conditions through Expressive Bidding. Only a solver handles multiple package conditions properly, and the Sourcing Twin synthesises six strategist roles around it (Spend, Contract, Market, Discovery, Scenario Architect, Data Scientist), producing the decision-ready artefacts that let the Senior SME catch the mistakes and the Category Lead retain every judgment call. Between rounds, Inter-Round Optimization shows each supplier the share of the award they currently land and the scenario edges where a small move flips the coin in their favour. Leaders sharpen on the items that widen their lead, challengers see uplift-or-downfall pricing, tailers see the route back into the field. Every participant leaves with a Path to Win, no participant is used purely as a stalking horse, and the award respects the structural offer and package conditions each one brought.
Wouter's Closing Thought
"The technology is ready. It's been ready for years. The only question is whether procurement teams are prepared to change their mindset and fully leverage it. If they are, we're here to help them win."
Wouter Stegenga, Founder OptiProq.
