IT Services and IT Consulting Curitiba, Paraná 501–1,000 employees Founded 2015 Privately Held

Olist operates a multi-module e-commerce and payments ecosystem for Brazilian merchants, spanning marketplace logistics, seller tools, and credit/financing operations. The tech stack reveals a security-first maturity level—XDR, SIEM, SOAR integration sits atop AWS infrastructure—while active projects signal a pivot toward AI-driven automation in credit operations, receivables, and pricing, suggesting fintech is becoming a core revenue driver alongside marketplace services. Product and support hiring dominates over engineering, indicating a sales/operations-led go-to-market rather than a platform-scaling phase.
