    Echo
    July 23, 2026

    An adaptive AI system that dynamically allocates compute and selects from a pool of open-weight models to maintain performance while reducing costs. Available via chat UI and OpenAI-compatible API.

    Tracer-LLM
    Early 2026

    An open-source routing layer for optimizing LLM calls. The project gained significant traction with over 1,000 GitHub stars.

    HUD (hud-mode)
    August 2026

    A compact heads-up display for coding agents, specifically designed for Emacs (hud-mode).

    Market Position

    Tracer positions itself as a more efficient alternative to frontier models like Claude Fable, achieving comparable performance at significantly lower costs through intelligent coordination of open-weight models rather than just simple routing.

    Leadership

    Founders

    AR

    Adam Rida

    Founder and CEO of Tracer. Previously a PhD candidate at Sorbonne University/CNRS specializing in ML interpretability. Built applied ML systems in finance and insurance. Founded DeepRecall, which he bootstrapped to €100k ARR in under 3 months as a solo founder.

    Executive Team

    AR

    Adam Rida

    Founder & CEO

    ML researcher and engineer with a background in interpretability and applied ML systems.

    Board of Directors

    Founding Story

    Tracer grew out of internal research and tooling developed by Adam Rida while building DeepRecall. After open-sourcing the routing layer (Tracer-LLM) and seeing rapid adoption, Rida pivoted to focus entirely on the 'coordinated intelligence' paradigm, founding Tracer Research Lab.

    Business Model

    Revenue Model

    API usage fees (OpenAI-compatible API) and enterprise-specific workload optimization services.

    Pricing Tiers

    API Usage
    $10/M input tokens, $50/M output tokens

    Estimated costs based on performance benchmarks vs Claude Fable.
