Notch Tech Stack

AI customer support agent for regulated industries with compliance guardrails

Technology, Information and Internet New York, NY 11–50 employees Founded 2021 Privately Held

Notch builds AI agents for customer support in compliance-heavy sectors, combining orchestration logic with structured data capture. The tech stack—React + Node.js + PostgreSQL + Redis + AWS container services—reflects a full-stack SaaS architecture built for scale, while active projects around LLM/vector architecture, distributed queues, and AI agent deployment signal heavy investment in reliability and multi-tenant orchestration. Pain points centered on scaling to 100k+ messages/day and complex decision logic suggest the core challenge is making AI agent outputs predictable and auditable in regulated environments.
