Fintalk Tech Stack

Conversational AI platform for customer service and payments in Brazil

Software Development São Paulo, SP 51–200 employees Founded 2019 Partnership

Fintalk builds conversational AI for enterprise customer service and payments, deployed across retail, financial services, and telecom in Brazil. The tech stack is heavily orchestration-forward (n8n, Make, Zapier, Dialogflow, IBM Watson) rather than in-house LLM work — a pragmatic choice for rapid deployment in legacy-system environments. Active projects reveal two concurrent scaling challenges: a new tap&pay payments product built from scratch, and manual API integrations that the team is now automating. Hiring velocity is accelerating across engineering, data, and product, suggesting a pivot toward payments alongside core conversational AI.
