Find engineers and founders in Greylock’s portfolio

Greylock’s portfolio is a curated bet on the next wave of category-defining companies. The list above ranks Greylock-backed companies by current headcount, drawn from public LinkedIn and Crunchbase records. With 338 matching companies in our index, the depth of senior engineers, founders, and operators is significant.

Greylock’s companies tend to share a profile — strong technical founders, fresh capital, and access to the Greylock network. Hiring from these companies often means hiring from one of the most curated talent pools in tech.

Refolk turns this list into a search. Ask for “Greylockportfolio companies hiring senior ML engineers” or “founders of Greylock-backed companies who left in the last year” and Refolk returns a fresh ranked shortlist.
