Comet Tech Stack

Model evaluation and observability platform for AI development teams

Software Development New York, NY 51–200 employees Founded 2017 Privately Held

Comet is a model evaluation and observability platform built for AI developers. The tech stack—React, TypeScript, Python, and Claude—reflects a developer-first product approach, while active projects around Opik (their observability tool) and developer-led growth indicate a shift toward capturing adoption at the engineering layer rather than through traditional sales. Current hiring is concentrated in engineering (5 roles) with mid-to-senior seniority, suggesting the team is building out depth rather than breadth.
