How Labspie works
Where does the data come from?
Startups come from the open Y Combinator directory dataset, refreshed daily. Unicorn valuations come from Wikipedia's list of unicorn startups. Research labs, mafias and communities are curated by hand with sources, and companies can submit or correct their own listing. The methodology page lists everything.
What is a startup mafia?
A group of founders who worked at the same company before starting their own. The name comes from the "PayPal Mafia", whose alumni went on to start LinkedIn, YouTube, Yelp and Palantir.
What is the Slice of the Pie Index?
A daily ranking of cities, countries and sectors by their share of AI-native startups, research labs and new companies. It shows who holds the biggest slice and who is gaining.
How do I get my company or lab listed?
Submit it through the form. Every entry is checked by hand, usually within a few days, and appears on the map at the next morning's refresh. Listing is free.
How often does it change?
The map, unicorns, events and the Index rebuild every morning. Wikidata companies, open-model downloads and the UK register are pulled weekly. Each page shows when its data was last refreshed.
Can I use the numbers in an article?
Yes. Cite Labspie and link to the Index so readers can check the method. CSV downloads of the main tables are on the Index page.
