About Fidelity Horizon
Fidelity Horizon AB is a pre-seed AI infrastructure company headquartered in Stockholm, Sweden. Founded in 2025, we're building governed AI infrastructure grounded in one mathematical framework.
AI systems need governance infrastructure, not just guardrails
The AI industry has built powerful models but almost no infrastructure for governing them. Monitoring tools observe after the fact. Probabilistic guardrails add uncertainty on top of uncertainty. Compression tools optimize without proof of safety.
We believe the solution is one mathematical framework across the full AI lifecycle, from training through inference to verified output. Not a collection of unrelated tools, but one framework where insights from each stage strengthen the others.
Conservation of Fidelity is that framework. It enables three products that share a common foundation: MCG for understanding model structure, TTU Router for intelligent inference, and CoF Audit for deterministic verification. Each product is independently valuable. Together, they form the governance infrastructure that AI systems need.
Three products, one framework
MCG
Model intelligence platform. Map neural network structure, identify redundancy, enable verified optimization.
Learn more →TTU Router
Response-aware inference routing. Measure quality per response, route to the right model.
Learn more →CoF Audit
Deterministic verification. ALLOW/BLOCK with cryptographic audit trails.
Learn more →Pre-seed, verified results, seeking partners
Verified across scales
Results verified on public benchmarks across architectures from 11M to 72B parameters. Every claim backed by reproducible experiments.
Mathematical foundation
Conservation of Fidelity provides the mathematical framework. Not a portfolio of unrelated tools, one framework where insights from each stage strengthen the others.
Protected approach
The mathematical framework and product implementations are protected through filed intellectual property covering training optimization, inference routing, and deterministic verification.
