Sereno
Continuous mental-health platform with 1-on-1 therapy, guided content and an NR-1 corporate panel
Summary
A B2C+B2B product blending therapist matching, video sessions, emotional journaling and an anonymous psychosocial-risk panel for companies — fully compliant with NR-1.
Mental health became mandatory on the corporate agenda after Brazil's new NR-1, but existing platforms are either too expensive or treat care as a one-off benefit. Sereno was built around continuous care, with real professionals and data that respects patient confidentiality.
I led the full-stack architecture: B2C app, HR-facing B2B panel, clinical module for therapists, matching engine, multi-timezone scheduling, and health-insurance integration. Video over WebRTC, payments via Stripe.
More than 120,000 active users, 154 companies on B2B plans, and a 24-hour therapist match SLA sustained on 96% of requests over the last quarter.
Architectural decisions
Next.js 15 with server actions powering the consumer experience, a Node API on multi-tenant PostgreSQL to isolate clinical data per organization. Proprietary WebRTC room with Twilio TURN. Anonymous pulse aggregated via materialized views to honor LGPD and NR-1 obligations.
