Haroldo Jacobovicz Applies Technical Expertise Across Business Sectors
The career trajectory of Haroldo Jacobovicz illustrates how specialized training can find applications beyond traditional fields. After completing seven years at Military College and studying civil engineering at the Federal University of Paraná, he directed his technical aptitude toward information technology during Brazil’s early digital transformation period in the 1980s.
Family context played a role in his development—his father Alfredo combined engineering practice with university teaching, while his mother Sarita broke new ground as one of Paraná’s first women civil engineers. However, Jacobovicz pursued a different professional direction when he recognized untapped potential in emerging technology sectors.
His entrepreneurial instincts emerged before graduation when Haroldo Jacobovicz and three technically-oriented classmates established Microsystem. The company sought to modernize retail operations through computerized inventory management. Though technically sound, the venture ended after two years as small businesses weren’t yet ready to adopt such solutions—a market timing lesson that would shape his future business decisions.
Following this experience, Jacobovicz joined Esso (later Exxon Mobil), where his analytical skills distinguished him among numerous engineering applicants. Starting in sales, he advanced to market analysis and eventually managed commercial tactics at the company’s Brazilian headquarters. His responsibilities increasingly centered on data-driven decision-making, reinforcing his interest in digital applications.
When economic policies under the Cruzado Plan affected the fuel industry, Haroldo Jacobovicz reevaluated his professional path. He transitioned to the Itaipu Hydroelectric Plant as a Technical Director advisor, returning to Paraná while observing technology implementation differences between private corporations and government organizations.
This diverse professional background informed his next venture when he returned to entrepreneurship after four years in the public sector. He founded Minauro, introducing a computer rental and maintenance model tailored to government procurement requirements. This approach gained traction through competitive bids across multiple Brazilian regions.
His business portfolio expanded when he incorporated software capabilities through strategic acquisitions, adding tax, financial, administrative, health and education management solutions. These developments led to the e-Governe Group, which continues providing digital government services to municipalities throughout Brazil.
In 2010, Haroldo Jacobovicz ventured into telecommunications by establishing Horizons Telecom with input from Renato Guerreiro, the inaugural president of Brazil’s telecommunications regulatory agency. Targeting corporate clients with specialized connectivity solutions, the company grew into a recognized industry presence over the following decade before being acquired in early 2021.
Following this transaction, Jacobovicz launched Arlequim Technologies in 2021, focusing on computer virtualization services that enhance performance without hardware replacement. This approach addresses efficiency needs while supporting broader technology access by extending the productive life of existing equipment investments.
Throughout these various business initiatives, Haroldo Jacobovicz has consistently identified practical applications for technology across different sectors. His professional evolution demonstrates how technical knowledge combined with market awareness can generate business opportunities that bridge organizational needs with emerging technological capabilities.
