David Radszuweit

Founder & CEO · LineSpotting · Sweden · Born 1974

He goes in where delivery has stalled, puts a number on the value within two weeks, then builds the system that makes the improvement stick. For three decades that craft was consulting and turnaround. Now it is AI — on the network, at the edge, and in the P&L.

The thread

What buyers of distressed or underperforming businesses purchase is improvement potential. That is the same product David has sold since the nineties: enter a stuck operation, find the bottlenecks, quantify the value before anyone writes a plan. At the Swedish Social Insurance Agency (Försäkringskassan) that two-week discipline identified at least 150 million euro per year in recurring savings, plus a portfolio of mobile and portal modernisation proposals.

The degree on the wall is a Master in Film & Television (Bond University) — not computer science. The substance is elsewhere: assembler in the mid-eighties, RAS remote access for Deloitte’s offices two decades before “remote work” was a slogan, and today edge ML and AI-run infrastructure in production. Six Sigma Black Belt since 2009. CISSP. IPMA Level B. The method is formal; the delivery is hands-on.

“What you buy is improvement potential. My job for thirty years has been to walk into something that does not deliver and name the value inside two weeks. Now I do it with AI.”

LineSpotting — proof on his own P&L

Since 2022 he has run LineSpotting, an AI incubator with 25+ parallel projects across energy, IoT, water, waste and critical infrastructure. The firm scaled to 85 people. After he applied AI to the company’s own operations, the same portfolio runs with a single person at the centre. Not a client pilot — his own accounts.

Reuse is the design rule: a concept that works in one company should roll into the next. That is why AI IT Department ships as a finished package — site, PDF and PowerPoint from one source — Meraki-API-driven operations, roughly half the headcount to run the same estate, measured security posture up about 17%. It is the same logic behind Alutbildningar.org (making adoption repeatable for leaders and teams) and behind ai.ze.mt, a prompt optimiser and cost router that sends each job to the cheapest model that can still do the work, with token, cache and budget tracking per job.

He builds the hard path end-to-end

OCCDEC is not a slide. It is acoustic event detection in production: YAMNet TFLite on Jetson Nano at the edge, 16 kHz in overlapping three-second windows, ~180 ms inference per chunk, 521 sound events mapped to fifteen threat classes. Each sensor calibrates its own acoustic fingerprint in thirty seconds. Uncertain events go to a human review queue; approved annotations retrain the model and roll out over-the-air. False alarms down about 85%; alarm out in under a minute. Full MLOps loop — not a diagram.

Where he has been

How he works

Discovery workshops that put leadership and engineers in one room. Use cases prioritised by effect, feasibility and effort — Six Sigma, not opinion. Implementation with vendor selection, technical validation and programme control. Tooling that makes the next deployment cheaper than the last. Travel four days a week is normal; delivery experience across Sweden, Australia, Estonia, Finland, Norway, Germany and France.

The four-slide talk you came from is one product in that portfolio: how to run IT infrastructure with AI so headcount and security move in the right directions at once. Sources, method notes and a worked NIST CSF 2.0 / ISO 27001 example sit next to it. The figures −50% and +17% are engagement averages from his own client work — not a vendor benchmark.
