Throughout his business career, Haroldo Jacobovicz has concentrated on delivering functional technology services adapted to Brazilian market conditions. His educational background—seven years at Military College followed by civil engineering studies at the Federal University of Paraná—provided analytical skills that he would apply in technology sectors rather than traditional construction.

This direction differed from family expectations, as his father combined civil engineering practice with university teaching and his mother was among the first women to become a civil engineer in Paraná state. However, Haroldo Jacobovicz was drawn toward emerging fields, using information gathered from newspapers and magazines to identify opportunities before they became widely recognized.

While completing his degree in the early 1980s, Haroldo Jacobovicz formed Microsystem with three technically-oriented colleagues. Their company offered computerized inventory tracking and sales management to retailers at a time when such systems were relatively new in Brazil. Though this venture closed after two years due to limited market adoption, it provided crucial lessons about timing that influenced his subsequent business approaches.

Seeking to develop his professional experience, Jacobovicz joined Esso (later Exxon Mobil), advancing from sales positions to market analysis roles that utilized computer-processed data. Economic pressures during Brazil’s Cruzado Plan, combined with personal considerations, eventually prompted his return to Paraná where he served as an advisor to the Technical Director at Itaipu Hydroelectric Plant.

His four-year public sector experience revealed how governmental procedures complicated technology implementation—a challenge he addressed through his next venture, Minauro. This company offered public agencies four-year computer rental contracts with equipment updates and maintenance, bypassing complex procurement requirements while ensuring access to current technology. This practical solution secured numerous government contracts throughout Brazil’s southern and southeastern regions.

Building on this foundation, Jacobovicz expanded into software by acquiring development companies specializing in public administration systems. This created the e-Governe Group, which continues to support Brazilian municipalities with digital tools for various governmental functions.

Identifying opportunities in corporate telecommunications, he established Horizons Telecom in 2010 in partnership with former Anatel president Renato Guerreiro. After developing this operation for a decade, he sold the company to investors in early 2021 and redirected his attention toward a new venture.

That same year, Jacobovicz launched Arlequim Technologies, focusing on computer virtualization services. This company improves performance capabilities of existing hardware across different market segments—businesses, government entities, and individual users including gaming enthusiasts. By enhancing computing power without requiring equipment replacement, this approach makes advanced digital functions more widely available.

Each of these business initiatives demonstrates Jacobovicz’s consistent approach of identifying specific technology needs within Brazilian contexts and developing practical solutions that address real operational challenges. His career reflects how understanding local market conditions can lead to service models that effectively support Brazil’s ongoing digital transition while extending technological benefits across various sectors.
