New York State hosts a significant cluster of companies operating in the crypto and blockchain sectors. These firms primarily engage in financial services, software development, and blockchain services, catering to institutional and individual clients. The group includes established players like Galaxy, a financial services firm specializing in digital assets, and Gemini, which provides a cryptocurrency exchange and custodian platform. Other notable companies are Fireblocks, offering secure digital asset infrastructure, and OpenSea, a peer-to-peer NFT marketplace.

How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
