Find engineers and founders in Benchmark’s portfolio

Benchmark’s portfolio is a curated bet on the next wave of category-defining companies. The list above ranks Benchmark-backed companies by current headcount, drawn from public LinkedIn and Crunchbase records. With 238 matching companies in Refolk’s index, the depth of senior engineers, founders, and operators is significant.

Benchmark’s companies tend to share a profile - strong technical founders, fresh capital, and access to the Benchmark 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 “Benchmark portfolio companies hiring senior ML engineers” or “founders of Benchmark-backed companies who left in the last year” and Refolk returns a fresh ranked shortlist.

How this list is built

Refolk pulled companies whose disclosed Crunchbase investor list includes Benchmark, ranked them by current employee count, and kept those with at least 5 employees. The list refreshes monthly.
