Stealth Startup is a 2–10 person team in Los Angeles scaling rapidly: 94 engineering hires posted in the last 30 days alone, with headcount acceleration across sales, product, and research. The stack spans React/Node.js frontend, Python/Go/Java backend, Kubernetes/AWS/GCP infrastructure, and emerging AI layers (Langchain, MCP adoption). Projects cluster around voice automation, prompt orchestration, AI agent deployment, and sales playbook automation — signaling a B2B platform combining voice/ML infrastructure with go-to-market tooling. Pain points (scaling voice platform, optimizing ML workloads, bridging clinician/insurance workflows) suggest domain-specific verticals alongside a platform play.
