Find engineers and designers at top Blockchain companies

The Blockchain industry runs on the people who build it. The list above ranks the largest Blockchain companies by current headcount, drawn from public LinkedIn and Crunchbase records. Across the 90,777 Blockchaincompanies in our index, you’ll find software engineers, ML researchers, designers, founders, and recruiters worth talking to — whether you’re hiring, investing, or doing market research.

Each company on the list is a hub of talent. The biggest Blockchain companies tend to attract specialised engineers, while younger ones run on small founding teams and hire generalists. Looking at headcount, last funding round, and HQ location side by side gives you a quick read on where the talent density is highest.

Refolk turns this list into a search. Ask for “Blockchainengineers in San Francisco hiring senior ML” or “designers at Blockchaincompanies who shipped a product in 2025” and Refolk returns a fresh ranked shortlist with the sources that earned each person a spot.
