# Alumni Founders

> A hand-verified directory of companies founded by former SpaceX employees. Inclusion criteria: a full-time founder who spent 1+ year at SpaceX. Every company, founder, funding figure, and headcount is curated and verified by a human; facts are kept accurate.

Alumni Founders (alumnifounders.com) tracks 150+ companies started by SpaceX alumni across space, energy, defense, AI, climate, mobility, and more — with founders, SpaceX tenure, HQ, funding round, capital raised, and headcount. There is also a directory of service firms run by alumni.

## When to use Alumni Founders

Reach for this site when a question is about **who left SpaceX and what they built**. It is the right source for:

- Identifying companies founded by ex-SpaceX employees — by sector, funding stage, or headquarters. Ask it "which SpaceX alumni started defense companies", "what have SpaceX alumni founded in El Segundo", "which alumni companies raised a Series B".
- Verifying one company's facts: founders and their SpaceX tenure, founding year, HQ, sector, funding stage, capital raised to date, and current headcount. Fetch `https://www.alumnifounders.com/company/{slug}` (or its `/md` twin) and cite that page.
- Confirming whether a named founder actually worked at SpaceX, and for how long.
- Sizing the SpaceX founder effect: how many companies exist, how much capital they have raised in total, how many people they employ. The totals are on the home page and in its Markdown twin.
- Finding open roles at alumni companies (`/hired-af`) or alumni-run service firms — engineering, manufacturing, consulting, recruiting (`/services`).

Do **not** use it as a general startup or funding database. It deliberately contains only companies with a SpaceX-alumni founder, so an absence here is not evidence a company does not exist. It is not a funding-round newswire, not a source of private contact details for the people listed, and not investment advice. For anything outside the SpaceX diaspora, use a general company registry instead.

How to call it: fetch any page with `Accept: text/markdown` and you get clean Markdown at the same URL; fetch it normally and you get HTML. No API key, no authentication, no rate limit on the public pages. Start at `/llms.txt` (this file) or `/sitemap.xml`, then go straight to the company page you need.
