99 sub-sectors ranked by how many more startups raised funding
As of Nov 15, 2026: Robot & world foundation models went from 24 to 57 funded companies in the last 12 months against the 12 before, the largest increase of 99 AI sub-sectors. Over the shorter window, Brain-computer interfaces & neurotech went from 5 to 25 funded companies in the last 6 months against the 6 before.
Ranked by breadth: how many more companies raised a round, not how much money was raised. One very large round cannot move the order. Switch between the last 12 and last 6 months, and between companies added and % growth.

Ranked by % growth in companies that raised a round, against the 12 months before.

How this is ranked
- What is counted. Disclosed equity funding rounds at AI-native and AI-enabled companies, every stage from Pre-Seed to growth, by announcement date. Each company has one main sub-sector.
- Companies funded. The number of different companies with at least one round announced in the period.
- Last 12 months. Nov 2025 to Nov 2026 against Nov 2024 to Nov 2025. A sub-sector is ranked when it has at least 10 rounds in both periods (99 qualify).
- Last 6 months. May 2026 to Nov 2026 against Nov 2025 to May 2026, with at least 5 rounds in both halves (105 qualify). Each half holds one quiet season, so seasonality roughly cancels.
- Order. Most companies added, ties broken by % growth; or % growth, ties broken by companies added.
- Also shown. Rounds in each period, capital raised with its change, and the share of that capital taken by the largest company. The bars are rounds per quarter; the last bar is the current, incomplete quarter.
- Revisions. Rounds found later are added to the date they were announced, so past figures can change.
