Spend Matters constantly updates its understanding of the state of the procurement tech market via RFIs for our SolutionMap dataset, vendor interviews, global event attendance and product demos with the aim of keeping tech-selection decision makers ahead of market trends. But we also endeavor to grow our understanding of the wants and needs of the customers using that tech – the practitioners. In this series of interviews we are talking to vendors about what their customers really want from them and how they are proposing to address those needs. Today we speak with Susan Walsh, founder of The Classification Guru, specialists in fixing dirty data.
