About Us
SUM Equities builds software across AI systems, agent observability, knowledge engines, and consumer applications. The portfolio includes a verifiable bidirectional knowledge engine grounded in number theory (SUM), a standards-native agent observability backend (HFAO), and a cross-platform kitchen management system in closed beta on Android with the web surface live.
The work ranges from low-level systems programming (Rust, Zig/WASM) through full-stack web platforms (TypeScript, React, Next.js) to AI/ML pipelines (DSPy, multi-model orchestration, vector search). What has shipped is deployed primarily on Cloudflare's edge network and Supabase; most of the portfolio is still in development, and each entry states which it is.
The common thread: taking complex technical ideas and turning them into working systems that people actually use. Not research papers — software.
