Lambda is a member of the [AI infrastructure](https://presspool.ai/niches/ai-infrastructure) map. Recently funded AI infrastructure companies: GPU clouds, inference, data, evals and agent infrastructure, with funding and how often AI apps name each. The map page lists the other companies in that market and how often AI answers name those companies. Company naming counts stay on the map and on the company record.

Sampling in progress. Presspool has no completed sample of the question `who is Stephen Balaban` for Stephen Balaban, so this page shows no naming rate. A rate is published only as answers, of attempts, by app, taken from observations already collected, along with the domains those answers cited. No count is estimated, and an empty sample is not reported as zero.

Whether AI answers name Lambda is reported on the company record. The sample on this page, when one exists, is the person question for Stephen Balaban. Cited domains are listed when that sample contains them. The index lists founders from A to Z, and no one pays to be included. Corrections need a public source and go to the [contact page](https://presspool.ai/contact). The record behind this page was built November 4, 2026.
