Refurbishers, ITAD teams, and B2B traders lose margin every single day — not because they lack AI, but because devices are misvalued, sorted too late, or processed with incomplete information. The problem is operational, not theoretical.
While the industry pours money into bloated, hallucinating AI stacks with unpredictable server costs, I chose the opposite path:
Radical lightweight engineering.
Fehr Algorithmus is a 400 KB deterministic logic core running natively on the Linux kernel.
No cloud. No GPU farms. No hallucinations.
Just millisecond‑fast, predictable logic built for real shop‑floor conditions — the same philosophy behind FehrWatch ERP.
⚡ What the system delivers in milliseconds
Instant Valuation
Enter a single device, paste an eBay link, or import a full XLSX list — the engine instantly returns the real market‑value median.
Device details, condition, and comps appear in one unified workflow.
Risk Automation
Automatic detection of red flags such as BIOS locks, expressed through a clear traffic‑light signal.
Repair Buffers
Spare‑part deductions and repair buffers are integrated directly into the margin math — the same arbitrage logic that secured an MSI Delta 15 for €463 against a €900 market value.
Batch Throughput
Import, deduplicate, classify, value, and document large hardware lists — without switching tools or juggling ten browser tabs.
🛠 Built for the shop floor, not the boardroom
This system wasn’t designed in a meeting room.
It comes from decades of hands‑on problem‑solving, where speed, determinism, and reliability matter more than buzzwords.
