NVIDIA's CEO resigned overnight. One command shows which single vendor can take your stack down.

On 11 November 2026, NVIDIA's CEO, Jensen Huang, resigned from his roles as President, CEO, and board member. This marked the first time a single vendor's executive departure could directly impact a company's operations. The resignation led to immediate changes in leadership, with CFO Colette Kress becoming interim CEO and Harvey C. Jones serving as the company's first board chair. Despite the resignation, Q3 FY2027 earnings were still scheduled for 17 November 2026, and shares fell nearly 10% in premarket trading.

The resignation of a single vendor can have significant consequences for an organization's stack. A single command—vendormap—can reveal which vendor holds the most influence over the entire stack, potentially causing a single point of failure. vendormap is a local, zero-dependency TypeScript CLI that reads Terraform, manifests, and code to report concentration per layer, along with a deterministic score and CI exit code.

It scans nine layers of the stack: cloud, GPU, model, registry, identity, DNS-CDN, payments, CI, and data.

The tool's scoring system measures concentration using a Herfindahl-style formula, evaluating the share of dominant vendor references and generating a score from 0 to 100. If a layer has at least one vendor with two or more references, it is labeled as "SINGLE-POINT," indicating a potential vulnerability. The overall concentration score is determined by the worst category score, and the overall verdict is the worst category verdict.

If the concentration score is 100, the stack is deemed a "SINGLE-POINT," meaning it is highly vulnerable to a single vendor's failure.
