I’m Willemijn van Oorsouw, a Data Architect with a Business & Strategy Focus. With a background in enterprise integration, data governance, and scalable architecture, I’ve spent years bridging the gap between data and decision-making. I’ve seen technically sound data projects fail—not because the data was wrong, but because the story didn’t land. 

I help data professionals transform from technical executors into strategic partners. Through practical training and tools, I teach how to think, speak, and act in business terms—so their data initiatives get approved, supported, and implemented with real business traction. 

Too many great data professionals get involved too late—or not at all. They pitch dashboards when the board wants strategy. They optimize pipelines no one prioritized. Not because they lack skill, but because they lack business literacy. I believe business literacy is the missing superpower in the data world—and it’s time we teach it. 

I work with mid- to senior-level data professionals who want to increase their impact. Data team leads who want their team to better align with business strategy. Individuals who know technical excellence is not enough – they want to be seen, heard, and trusted as strategic partners. 

I don’t teach fluff. I teach data professionals how to understand business models, strategic plans, and decision logic. Frame their data work in terms of impact, urgency, and value. Use known business frameworks (like value chains, KPIs, stakeholder maps) to pitch data initiatives that land. No roleplay. No jargon. Just practical business literacy grounded in real-world architecture work. 

With my training and tools, you will be involved earlier and more often in key business decisions. Get stakeholder buy-in without begging for it. Feel confident speaking in rooms where strategy is set—and data makes the difference. 7.
