The professional path of Haroldo Jacobovicz demonstrates a persistent interest in technology applications even when his formal training pointed elsewhere. After completing seven years at Military College and earning his civil engineering degree from the Federal University of Paraná, he made an uncommon career choice in the 1980s by focusing on information technology rather than structural design or construction management.

This direction might seem surprising for someone raised by parents deeply connected to civil engineering—his father Alfredo combined engineering practice with university teaching, while his mother Sarita broke gender barriers as one of the first women in Paraná’s engineering field. Yet Haroldo Jacobovicz was captivated by technological possibilities, regularly studying news publications to identify potential business applications ahead of market trends.

His entrepreneurial journey began before graduation when he collaborated with three technically-inclined friends to launch Microsystem, offering computerized inventory and sales management to retail establishments. Despite initial enthusiasm, this venture concluded after two years when it became apparent that the Brazilian market was not yet prepared for widespread digital adoption. This experience provided valuable insights about market readiness that would shape his future business decisions.

Seeking corporate experience, Haroldo Jacobovicz joined Esso (later rebranded as Exxon Mobil), where he progressed from sales positions to analytical roles focused on data-driven market assessment. Economic complications arising from Brazil’s Cruzado Plan price controls, combined with family considerations, eventually prompted his return to Paraná, where he accepted an advisory position with the Technical Director at Itaipu Hydroelectric Plant.

During four years in this public sector role, Jacobovicz observed how governmental procurement processes created obstacles for technology implementation. This realization sparked his next venture: Minauro, which addressed these constraints by offering four-year computer rental contracts with built-in equipment updates and maintenance services. This approach helped public agencies access current technology while navigating budget restrictions and asset management regulations—a formula that secured numerous government contracts throughout southern and southeastern Brazil.

His technology service portfolio expanded when he acquired software development firms that specialized in public administration systems, creating the e-Governe Group to provide integrated digital solutions for municipal governments. In 2010, Jacobovicz partnered with former Anatel president Renato Guerreiro to establish Horizons Telecom, developing this operation into a significant telecommunications provider before selling to investors in early 2021.

That same year, Jacobovicz founded Arlequim Technologies, focusing on computer virtualization services. This newest venture enhances performance of existing hardware across corporate, governmental, and consumer markets, including gaming enthusiasts. By optimizing available computing resources without requiring new equipment purchases, this approach makes advanced digital capabilities accessible to broader segments of the Brazilian market.

Throughout these ventures, Jacobovicz has consistently identified ways to remove barriers between users and technology, creating business models that adapt to market conditions while extending digital capabilities to more participants in Brazil’s developing technology landscape.
