TAGNA Technology

What TAGNA Technology does

Legal entity Tagna Tecnologia de Automação Industrial LTDA, founded in 2012 in Brazil, operates as an industrial automation and Industry 4.0 consulting firm targeting large Latin American industrial enterprises in mining, metals/steel, and agroindustry. The firm has grown organically with no disclosed institutional funding, running a 101-250 employee operation headquartered in Belo Horizonte, Minas Gerais, and delivering projects across three Latin American countries. Its go-to-market is exclusively direct enterprise sales, marketed through a 'Fale com um XPERT' (Talk to an XPERT) consultation channel and supported by thought-leadership content (Insights blog, LinkedIn, YouTube, Giro 4.0 webinars).

TAGNA's core technology is the proprietary NEXUM Digital platform — an industrial software stack hosted on Google Cloud Platform with OPC integration, Python, machine learning, and advanced analytics. It comprises modular AI-based products: NEXUM Control (prescriptive multivariable control for thermal processes), NEXUM Balance (Data Validation and Reconciliation for mass/water/metallurgical accounting), NEXUM Health (predictive instrument-health monitoring and signal reconstruction), NEXUM Quality (statistical process control for chemical dosing), NEXUM Vision (computer vision for material-loss measurement), NEXUM Decision (AI-driven process learning and autonomous setpoint adjustment), NEXUM Scan (GPS/encoder-based collision prevention for yard machines), and NEXUM One (2025-launched platform for building custom AI-based industrial applications). NEXUM is delivered within a proprietary 'Método XPERT' methodology and resold through certified system integrator relationships with Rockwell Automation, Schneider Electric, Siemens, Emerson, and ABB.

The business model blends professional services engagements (industrial automation, control-system modernization, and PDAI strategic consulting under multi-year contracts) with platform/software revenue from the NEXUM Digital stack (licensing, implementation, and managed/subscription services). Commercial outcomes are anchored by named enterprise deployments delivering measurable results: 87% temperature-variability reduction and 7.66% gas-consumption reduction at RHI Magnesita; 75% reduction in tank overflow time at AngloGold Ashanti; multi-plant Rockwell PlantPAx automation at Inpasa (4 plants); port-automation modernization at Vale CPBS; remote yard-machine automation at Mosaic (3 machines) and EuroChem; control-loop performance gains above 13% at Gerdau; and mineral-process management at Yara Brasil. Pricing is opaque and quote-based, calibrated per project; 100+ applications installed across three countries underpin the scale of the deployed base.
