Find engineers and operators at companies in the United States
the United States is one of the densest markets for technology talent in the world. The list above ranks the largest companies headquartered in the United States by current headcount, drawn from public LinkedIn and Crunchbase records. With 498,696 matching companies in Refolk’s index, the depth of engineers, designers, product managers, and founders is broad across stages and industries.
Hiring in the United States usually means hiring out of these companies. The biggest names anchor the talent pool - every senior engineer in the United States likely has at least one of them on their resume - and the fast-growing ones generate the most movement.
Refolk lets you reach into this pool with plain English. Ask for “senior backend engineers in the United States who’ve shipped at scale” or “founders in the United States who left in the last year” and Refolk returns a ranked shortlist with the evidence behind each match.
