3441: How Abacum Became the Fastest Growing Tech Company in Spain

Finance leaders know the struggle of managing endless spreadsheets, juggling data from every corner of the business, and trying to plan for a world that changes by the hour. In this episode, I talk with Julio Martínez, Co-Founder and CEO of Abacum, about how his team is helping finance professionals move from reactive reporting to confident, real-time decision making.

Abacum was recently named the fastest growing tech company in Spain by Deloitte after increasing revenue by 6,733 percent in just four years. Julio shares the story behind that growth and explains how finance teams are transforming from back-office operators into true strategic partners. He describes how Abacum’s platform helps CFOs and FP&A teams create accurate forecasts, automate manual work, and build scenario models that answer “what if” questions in minutes instead of days.

We also talk about the role of AI in finance and why current large language models are not yet reliable enough for quantitative use cases. Julio discusses the need for precision, the importance of a human in the loop, and how new hybrid approaches are shaping the future of financial planning.

From Barcelona to New York, his journey reflects the global rise of data-driven finance and the growing strength of Spain’s startup ecosystem. Julio also leaves listeners with a thoughtful recommendation, Meditations by Marcus Aurelius, a book that continues to inspire him to stay grounded amid rapid change.

If you want to understand how technology is redefining financial planning and how strong foundations can fuel extraordinary growth, this conversation with Julio offers a rare look inside the engine of one of Europe’s fastest-rising tech companies.
