    Model Router
    Nov 2023

    The world's first 'model router' that dynamically routes every prompt to the best LLM in real-time, optimizing for cost and performance.

    Airlock
    Sep 2024

    Enterprise compliance automation suite that ensures new AI models meet safety and policy requirements.

    Model Gateway

    A unified API to access and switch between 200+ large language models.

    ARES (Agentic Research and Evaluation Suite)
    Jan 2026

    Open-source infrastructure for online reinforcement learning on coding agents.

    Market Position

    Pioneered the 'Model Router' category, positioning itself as a layer that abstracts away the complexity of choosing LLMs by using research-grade interpretability to route prompts more effectively than even GPT-4 in some cases.

    Leadership

    Founders

    EG

    Etan Ginsberg

    Co-founder. Previously an AI researcher at the University of Pennsylvania focusing on Anthropic's interpretability efforts. Sold previous NLP companies.

    SU

    Shriyash Upadhyay

    Co-founder and Principal Scientist. Previously worked on Google DeepMind's early scientific initiatives and Meta's superintelligence commercialization. Sold previous NLP companies.

    Executive Team

    EG

    Etan Ginsberg

    Co-founder
