Thesis
Radiology is the largest productivity bottleneck in Brazilian medicine. Exam volume grows faster than the number of trained radiologists.
Applied AI — not generic AI. Product built by a practicing radiologist, with real reporting, review and training workflows. LLM orchestration, Agentic RAG over radiology corpora, clinical NLP in Portuguese.
Three products, one lab. RadReport monetizes the commercial core. RadVenture and ResiProva widen the educational funnel and the brand's reach among residents — the next generation of radiologists.
Clinical governance from day zero. LGPD, appointed DPO, privacy/terms/security policies public on the corporate site.
