## What “cited by AI engines” means here

The [Machine Relations Index](https://machinerelations.ai/index) asks ChatGPT, Claude, Gemini, Perplexity, Google AI Mode and Google AI Overviews a fixed panel of buyer questions on a recurring schedule and records which websites each answer cites. A company counts as cited when its own website appeared as a source in at least one recorded answer between May 10, 2026 and October 10, 2026 (release `mri_score_v2.1+2026-10-10+f53dc9f073bc`). The panel asks buyer questions across 24 industry categories, not questions about these companies by name, so “not yet” means no recorded answer cited the company's site. A company whose market sits outside those categories can be absent for that reason alone.

## Questions

### Which AI startups raised the most money the week of October 5, 2026?

SignSplit, $400 million (Seed), Nous Research, $90 million (Series B) and Namespace, $42 million (Series B).

### How much did AI startups raise the week of October 5, 2026?

The 22 AI rounds confirmed here include 17 announced in dollars, which total $800 million. 5 rounds were announced in another currency and are listed as announced, not converted.

### Do AI answer engines already know these companies?

1 of the 22 companies had been cited in at least one AI answer recorded by the Machine Relations Index between May 10, 2026 and October 10, 2026: Hadrian. A funding announcement does not by itself put a company into AI answers.

## How this list was built

Rounds come from public announcements: the company's own release where one exists, and the outlet that reported it. This week's candidates came from a funding-announcement feed over TechCrunch, Tech.eu and EU-Startups and from the daily funding reports of AlleyWatch, Raise Track, Tech.eu, EU-Startups and Crunchbase News; 22 of them met the AI rule and were confirmed at the company's own announcement and an outlet. Each entry was checked against its source for the amount, the round and the lead investors. A company is included when its own announcement describes the company, not one feature, as AI or as built for AI. [Full method](https://presspool.ai/method).
