About Fidelity Horizon
Fidelity Horizon AB is a pre-seed AI infrastructure company headquartered in Stockholm, Sweden. Founded in 2025, the company builds governed AI infrastructure grounded in the Conservation of Fidelity mathematical framework.
Governed AI infrastructure
We build tools that make AI models more efficient to train, cheaper to serve, and safe to trust. Three products, one mathematical framework, verified across architectures from 11M to 72B parameters.
Mathematical foundation
All products are grounded in Conservation of Fidelity — a mathematical framework that defines computation bounds across AI systems. This is not a portfolio of unrelated tools; it's one theory applied at different lifecycle stages.
23 provisional patents
23 provisional patents protect the theoretical foundation and product implementations across training optimization, inference routing, and deterministic verification.
Verified results
Every claim on this website is backed by reproducible experiments. 35–78% FLOP reduction (MCG), 51% cost savings at 99.8% quality (TTU), 0% false GREEN across 58 eval cases (CoF Audit).
