MANTEST Soluções Integradas

What MANTEST Soluções Integradas does

MANTEST Soluções Integradas (legal name Mantest Engenharia Elétrica) is a Brazilian specialized electrical engineering services firm headquartered in the São Paulo region, with origins tracing back to 1985 when founder Jorge Luis Gennari established Genesis Engenharia e Sistemas. Across 40 years of continuous operation, the firm has completed over 3,000 interventions in Electrical Power Systems (SEP) and built a client base of large Brazilian and international enterprises spanning data centers, hospitals, financial institutions, oil & gas operators, manufacturing, broadcasting, and commercial real estate. Named reference clients include Petrobras, TV Globo, Banco Santander, Bunge, NIC.br, Citibank (Uruguay), Goodyear, XP Investimentos, Hospital Santa Joana, Pátio Victor Malzoni, and an unnamed hyperscale data center operator.

The company's offering is organized around five service pillars: (1) Applied Engineering — power system studies including short-circuit, protection coordination and selectivity, Arc Flash (ATPV), harmonic flow, motor starting transients, VFTO, and BESS modeling; (2) Electrical Commissioning — for substations, transformers, protection systems, generators, UPS, and integrated data center systems; (3) Maintenance and Normalization — preventive/corrective maintenance, NR-10 compliance, PIE dossier issuance, and ANEEL REN 915 electromagnetic field measurements; (4) Energy Management — efficiency programs, demand control, power factor/harmonic correction, free energy market (Mercado Livre de Energia) consulting, and renewable integration; and (5) Training — IEEE 493-based mission-critical electrical and risk analysis training for enterprise maintenance teams. Technical differentiation is concentrated in specialized computational modeling (VFTO, BESS, arc flash), anti-corruption and engineering regulatory compliance, and the founder's domain credentials across the electrical power systems lifecycle.

MANTEST operates a founder-led enterprise B2B services model, reaching clients via direct sales, the mantest.com.br corporate website, WhatsApp, telephone, and email, supplemented by content marketing via the "3 Minutos Elétricos" podcast and thought leadership through DNCE-ABRAVA. Engagement structures are custom project-based contracts and multi-year retainers, with revenue generated from professional services billing. The firm is privately held with no disclosed external institutional investment, and is governed directly by the founder under a documented compliance framework covering anti-corruption, tax, labor, environmental, and engineering practice requirements. Recent operational footprint extends to international project sites in China (FPSO P-71 at Yantai), Uruguay (Citibank Montevideo), and England (Cummins factory for Globo).
