Overview
Synergy Group is a privately controlled South American conglomerate created and owned by Germán Efromovich. Headquartered in Rio de Janeiro, Brazil, the group developed a diversified portfolio spanning commercial aviation, aerospace services, oil and natural-gas exploration, hydroelectric generation, telecommunications infrastructure, shipbuilding, technical inspection, radiochemistry, radiopharmaceuticals, agriculture, and hospitality. Aviation has been the group’s most internationally visible activity. Through Synergy Aerospace, a group subsidiary headquartered in Bogotá, Synergy assembled interests in airlines and aviation businesses across Colombia, Brazil, Ecuador, and El Salvador. Its portfolio has included Avianca and Tampa Cargo in Colombia, Avianca Brasil, VarigLog, and Synerjet in Brazil, VIP and AeroGal in Ecuador, and the airlines associated with Grupo TACA in El Salvador. Synergy Aerospace became the principal shareholder of the holding structure created to combine Avianca and TACA’s airline operations. Synergy Group held 66.66% of the resulting Avianca-TACA holding company, while Kingsland Holding of El Salvador held the remaining 33.33%. The group’s aviation strategy was not limited to airline ownership. It also included aircraft maintenance through Digex Aircraft Maintenance, business and regional aviation through Senior Taxi Aéreo and Synerjet Brasil, aerospace and defense initiatives through EAE Aerospace Solutions, and European coordination through Synergy Aerospace Europe and Synergy Europe. In March 2011, Synergy Aerospace established a joint venture with Israel Aerospace Industries. The proposed partnership was intended to develop and market defense and aerospace capabilities including unmanned aerial vehicles, transport platforms, aircraft modernization, intelligence and surveillance systems, and radar technologies. The group also expressed interest in investing in Flight Technologies, a Brazilian tactical unmanned-aerial-vehicle manufacturer serving defense applications. Synergy’s diversification extended into maritime and industrial infrastructure. Its EISA Shipping Agency and shipyard-related activities included construction of a patrol vessel for the Brazilian Navy. The group also participated in oil and gas exploration in South America, hydroelectric power generation, telecommunications construction, inspection services, radiochemistry and radiopharmaceuticals, agriculture, and hospitality. This portfolio gave Synergy the profile of an investment and operating group rather than a consumer-facing product brand. The group also pursued expansion beyond South America. In 2012 it created Synergy Aerospace Europe and later Synergy Europe in Luxembourg to coordinate potential European airline investments. Synergy became a candidate in the privatization of TAP Portugal and explored cooperation with European investors, including EuroAtlantic Airways. In June 2015, however, its bid was unsuccessful; TAP was awarded to the Gateway consortium, associated with Humberto Pedrosa and David Neeleman. Publicly available reference material describes Synergy as a broad, entrepreneur-led conglomerate whose principal strategic themes were transportation, aviation integration, energy, and infrastructure. The available material does not establish a current corporate structure, current operating status for each subsidiary, present ownership percentages, or a current official website, so those details remain unspecified here.
History
Synergy Group emerged as an entrepreneur-led South American conglomerate under Germán Efromovich. Rather than developing around a single consumer product, it built a portfolio of operating companies and investments in sectors connected with transportation, infrastructure, energy, and specialized engineering. Rio de Janeiro became the group’s headquarters, while its aviation subsidiary, Synergy Aerospace, operated from Bogotá and managed much of the group’s airline-related activity. Aviation became Synergy’s central international platform. The group accumulated or controlled interests in airlines and aviation companies in Colombia, Brazil, Ecuador, and El Salvador. The portfolio described in reference material included Avianca and Tampa Cargo, Avianca Brasil, VarigLog, Synerjet, VIP, AeroGal, and Grupo TACA. Synergy’s most important structural move was the integration of Avianca and TACA interests into Avianca Holdings, a holding company in which Synergy held 66.66% and Kingsland Holding held 33.33%. This arrangement made Synergy the major shareholder in the combined airline group and gave it a regional platform across several Latin American markets. The aviation portfolio was supported by related businesses. Digex provided aircraft-maintenance capabilities, while Senior Taxi Aéreo and Synerjet Brasil represented additional aviation-service activities. In November 2012, Synergy Aerospace Europe was established as a European subsidiary. The group subsequently created Synergy Europe in Luxembourg while considering a possible acquisition of TAP Portugal. These entities were intended to organize European operations and facilitate relationships with potential investors and airline partners. Synergy also pursued aerospace and defense activities. In March 2011, Synergy Aerospace formed a joint venture with Israel Aerospace Industries. The planned scope included tactical unmanned aerial vehicles, multi-mission transporters, aircraft modernization, intelligence, surveillance and reconnaissance systems, and radar technologies. EAE Aerospace Solutions was established in Brazil as a shareholder and holding vehicle for related Brazilian activities. The group also considered investing in Flight Technologies, a São José dos Campos manufacturer of tactical unmanned aircraft for the Brazilian Army. Beyond aviation, Synergy operated or invested in a wide range of activities. Its described portfolio included oil and natural-gas exploration throughout the region, hydroelectric power plants, telecommunications infrastructure construction, shipbuilding, technical inspection, radiochemistry, radiopharmaceuticals, agriculture, and hospitality. EISA Shipping Agency and shipyard activities were associated with construction of a 500-ton patrol ship for the Brazilian Navy. These businesses reinforced the group’s emphasis on infrastructure and technically demanding industries. The TAP Portugal initiative represented an attempt to extend Synergy’s regional aviation strategy into Europe. The group competed in the Portuguese carrier’s privatization process and considered cooperation with European investors, including EuroAtlantic Airways. In June 2015, the bid was unsuccessful, and the Gateway consortium was selected instead. The available reference material does not provide a complete later history of Synergy Group, nor does it confirm the current status of all named subsidiaries or investments. Accordingly, the group’s present operating footprint and corporate structure require further verification.
