Núcleo Jornalismo

What Núcleo Jornalismo does

Núcleo Jornalismo is an independent Brazilian investigative journalism organization operating as Volt Data Lab (VOLTDATA AGENCIAMENTO DE NOTICIAS LTDA, CNPJ 37.307.891/0001-33), founded in 2014 by Sérgio Spagnuolo and headquartered in São Paulo with a remote team distributed across seven Brazilian states. The company produces data-driven reporting on the societal impact of digital platforms, artificial intelligence, and Big Tech in Brazil, combining original investigative journalism with proprietary technology tools that include Legislatech (a SaaS platform monitoring 29 government agencies and 600+ data sources, processing 2.75 million documents with 1,000+ active users), Legislatech AI (a generative AI search engine for Brazilian federal legislation built with Microsoft support), Nuclito (an AI chatbot trained on Núcleo's content), and MonitorA (an observatory for political gender-based violence on social media, expanded to Bolivia and Colombia). The underlying technology stack uses Ghost CMS hosted on Hetzner, AWS SES for newsletters, and open-source infrastructure.

The business model blends diversified revenue streams: institutional grants (R$1.3M+ received in 2025 from Luminate, Microsoft, Instituto Serrapilheira, ICFJ+, and Pulitzer Center), recurring reader revenue (880+ paid supporters and digital subscribers growing 95-96% YoY at R$5-10/month price points), technology services via Legislatech subscriptions (R$9.90/month), qualified advertising through Publi Parceira partnerships, and consulting. Distribution centers on direct-to-reader channels—six newsletters totaling 39,500+ subscribers, the NucleoHub Discord community (1,152 members), 14+ social media platforms, an editorial partnership with Folha de S.Paulo, and the Núcleo Investiga podcast. Core audiences include Brazilian readers interested in technology and digital platforms, journalists/media professionals, academic researchers (371 researchers in Ciência Monitorada program), civil society organizations, and government entities. Notably, in June 2026, Núcleo announced a strategic pause to "reevaluate operations, business, and audience" citing declining web traffic (down 52% in 2025 due to Google AI Overview impact), reduced content output (32% fewer URLs), and shifting journalism economics.
