Find engineers at Series A companies in the United States

Series A companies in the United States are some of the fastest-moving employers in the market. The list above ranks the largest Series A-stage companies headquartered in the United States by current headcount, drawn from public LinkedIn and Crunchbase records. With 6,786 matching companies in Refolk’s index, the density of senior engineers, designers, and founders is unusually high.

At Series A, teams tend to be small, ambitious, and on the hunt for senior talent. The companies on this list are good signals for where the the United States talent market is heating up - and for which engineers and founders are about to become tomorrow’s operators.

Refolk converts this list into a live search. Ask for “founders of Series A companies in the United States” or “senior engineers at Series A companies in the United States hiring” and Refolk returns a ranked shortlist with evidence behind each match.
