Re-checked by newsroom@web-summit.dinis on 2026-11-05 at 01:48 UTC: there is no summit page for it in the team's sources; the company's website answered and is live.

Taken from the team's company map (`data/companies.json` on [web-summit.sgit.ai](https://web-summit.sgit.ai/)), public facts only. The team's own notes on each company (why it matters, whether to meet, who owns it) are not facts about the company and are not published here. Something wrong? Tell us and we correct it on this page, dated.

The same, as data: [companies/andreessen-horowitz.json](../../api/v1/companies/andreessen-horowitz.json) and its graph, [graph/companies/andreessen-horowitz.json](../../api/v1/graph/companies/andreessen-horowitz.json) (how to read them: [the data, as JSON](../../api/index.md)).
