Crisis Text Line Tech Stack

24/7 text-based mental health crisis support via volunteer network

Non-profit Organizations New York, New York 201–500 employees Founded 2016 Nonprofit

Crisis Text Line operates a text-messaging platform connecting people in mental health crisis with trained volunteer counselors, available in English and Spanish. The tech stack reveals a mid-stage infrastructure modernization underway: PHP is being replaced with Go across core services, while Hugging Face and Transformers are actively adopted—indicating movement toward ML-driven triage or routing of incoming conversations. Engineering-heavy hiring (5 of 7 open roles) paired with infrastructure projects (API-first architecture, observability, incident management) suggests the nonprofit is transitioning from a volunteer-centric operation to a more scalable, reliability-focused platform.
