IT Services and IT Consulting São Paulo, SP 201–500 employees Privately Held

Certta operates a verification hub serving banks, fintechs, payment processors, and delivery platforms across Brazil with identity verification, KYC/AML, and fraud prevention. The tech stack (Node.js, .NET, React, AWS Lambda, DynamoDB) points to a microservices-based platform built for transaction throughput. Active hiring across engineering and sales—with a 5:3 ratio and accelerating velocity—suggests they're scaling both product development and go-to-market in parallel, though sales pain points (qualified leads, pipeline expansion, prospecting bottlenecks) indicate the GTM side is under pressure.
