Ransomware Readiness, and the First Day
Ransomware is the incident that closes small businesses. This lesson covers how it actually unfolds, the decisions that get made badly under pressure, whether to pay, what the first day looks like, and the preparation that turns a business-ending event into a bad week.
The Handful of Controls That Do Almost All the Work
Small businesses are told to do everything and can afford almost nothing. This lesson identifies what small organisations are actually attacked with, why that differs from what security marketing describes, and the small set of controls that removes most of the realistic risk.
The Risk You Bring In: Your Own AI Tools
The other direction of the problem. Employees using AI tools create exposure through data leaving the organisation, prompt injection turning an assistant against its user, malicious extensions, and code suggestions nobody verified. This lesson covers what to worry about and what is overstated.
Exception Handling: Where Planners Actually Spend Their Day
Supply chain systems handle the normal case; people handle everything else. This lesson covers why exception volume is the real workload, how to triage without automating away judgement, what a control tower does and does not solve, and why visibility is usually a data problem rather than a modelling one.
Care, Coordination, and What a Practice Is Paid For
Running these tools inside a design practice: documenting that care happened, the professional indemnity question, who owns generated output, coordination liability across consultants, and the parts of the work a client structurally cannot get from a tool.
The GENIUS Act, Risk, and the Honest Limits
The 2025 GENIUS Act turned stablecoins from an unregulated experiment into a defined instrument with reserve rules, permitted issuers, monthly attestations, and a ban on paying holders yield. This lesson covers what the law requires, why the yield ban shapes the whole business model, and the risks the rules do not remove.
Ways to invest, and how deals go wrong
You can own real estate as a landlord, as a passive partner, or as a share you buy in seconds, and each trades control for convenience. This lesson maps the ways to invest, the risk ladder from stable rentals to ground-up development, the four-phase cycle real estate always moves through, and the specific, repeating way over-leveraged deals collapse.
Why real estate is really a debt business
The reason real estate builds fortunes is not the buildings, it is the borrowing. Leverage lets you control a large asset with a small amount of cash, multiplying every dollar of return, and every dollar of loss. Learn the math of leverage, cash-on-cash return, why the same mechanism that creates wealth also wipes people out, and when borrowing actually helps versus hurts.
Concentration and resilience: what it takes to de-risk a chip supply chain
Mapping the single points of failure in semiconductor production, why building fabs elsewhere is necessary but nowhere near sufficient, the real toolkit of resilience strategies with their costs, and a transferable method for analyzing any concentrated supply chain.
Concentration and risk: single points of failure
The geographic and corporate concentration of the chip supply chain expressed as engineering risk — single points of failure, the cost of redundancy, hedging strategies, and the customer-side concentration that mirrors the supply side. Structural analysis, not prediction.
Governance, Risk, and Continuous Measurement
Responsible AI is a practice, not a slogan. This lesson covers the EU AI Act's four risk tiers and what each requires, model monitoring and drift detection, hallucination rates and human-in-the-loop design, guardrail KPIs, and how to run governance as a measured, auditable discipline rather than a compliance checkbox.
