Tractian's industrial-AI bet: $120M Series C, Forbes AI 50, ~R$250M revenue

Tractian was founded in Brazil in 2019 by Igor Marinelli, Gabriel Lameirinhas and Leonardo Vieira. Marinelli and Lameirinhas had been software engineers at International Paper, where they saw how backwards industrial machine monitoring was; Marinelli's father worked on factory floors, keeping the founders close to the maintenance problem. The bet: factories of almost any size would adopt a cheap sensor plus AI subscription that predicts breakdowns before they happen.

The product attaches wireless sensors to rotating assets — motors, pumps, compressors — and transmits vibration, temperature and electrical data over cellular networks. Software turns that data into diagnostics, alerts, checklists and work orders, and the models learn each machine's specific failure signature over time. TechCrunch covered the US$15M Series A led by Next47 in May 2022, reporting roughly 200 customers including John Deere, Bosch, Embraer and Hyundai.

By 2024 Tractian had moved its headquarters to Atlanta with offices in São Paulo and Mexico City, was the only manufacturing-focused company on the Forbes AI 50 list, and had filed 12 patents. Bloomberg Línea reported ~R$250M in annual revenue, 40% of it from outside Brazil, with clients such as Suzano, Dexco, M. Dias Branco and Nissan Brasil. In December 2024 the company closed a US$120M Series C led by Sapphire Ventures, with General Catalyst, Next47 and NGP Capital, at a ~R$4B (~US$720M) valuation.

Tractian's approach to the classic predictive-maintenance category was to make it cheap and self-service: rather than selling big enterprise projects, it sells subscriptions that include the hardware, letting maintenance teams start with one motor and expand from there.
