AI agent infrastructure companies: 8 verified, updated November 13, 2026
Presspool has verified 8 AI agent infrastructure companies. 6 of them announced a round in the last six months, most recently Daytona ($60M, October 20, 2026). Latest rounds: the 7 announced in dollars total $287 million.
A subset of Presspool's AI infrastructure map: companies whose fit on that map places them in AI agent infrastructure. Companies selling the layers other AI products run on: GPU clouds and neoclouds, inference and model-serving platforms, training data and web data for AI, evaluation, observability and testing for AI, vector and AI-native databases, and infrastructure for AI agents. Each company is already on the parent map, where it was taken from the company's own website and confirmed by an independent source, both linked on the entry. No company pays to be listed.
This map does not have its own weekly question set or answer sample. The questions and answer counts for these companies are on the AI infrastructure map.

What counts as AI agent infrastructure
This page lists companies already on the AI infrastructure map. A company is listed here when the fit recorded on that map names AI agent infrastructure before any other layer. It is not a separate check. Out of scope: companies on the AI infrastructure map whose fit names a different layer first, and anything the AI infrastructure map excludes. Companies whose product is an end-user AI application, and companies whose most recent announced round is more than 12 months old. Definitions are versioned; this is version 1. Corrections need a public source: see Contact.
