PSA | Profissionais SA Tech Stack

Corporate training and events platform connecting speakers with enterprise clients

Professional Training and Coaching São Paulo, SP 51–200 employees Founded 2010 Privately Held

PSA runs a full-stack event and training business—lectures, workshops, consulting—serving Brazilian enterprises. The tech stack reveals a sales-ops infrastructure built on HubSpot, Node.js/React frontend, and MySQL/MongoDB persistence, with hiring frozen at 6 roles (only 1 posted in the last 30 days). The two-to-one ratio of sales hires to engineering signals a business model scaling go-to-market rather than product velocity, and internal pain points around conversion funnels and CRM data suggest the bottleneck sits in sales execution, not platform capability.

About PSA | Profissionais SA

PSA is a Brazilian corporate education company founded in 2010, headquartered in São Paulo.

The company operates across event production, training design, and corporate consulting. Engineering is minimal (1 active hire) relative to sales (4), indicating a service-delivery model where technology serves internal operations (campaign planning, CRM automation, reporting) rather than a core product.
