For decades, business agreements were formalized with ink on paper. As enterprises went digital and global, contract signing became one of the last workflows still running offline.
eSign.AI was built for that gap. The platform covers the full contract lifecycle, follows e-signature regulations in 100+ countries and regions, supports SES, AES and QES, and operates data centers in Hong Kong, Singapore, Frankfurt and Mainland China.
Enterprises use it to sign, manage and verify contracts from anywhere, with signer identity verified through local routes and every record kept audit-ready.
Teams in Hong Kong, Singapore, Hangzhou, Beijing and Shanghai support customers across Asia-Pacific, Europe and the Americas, with service coverage extending to Malaysia, Indonesia, Vietnam, Thailand and the Philippines.

Local teams in Singapore, Malaysia and Indonesia handle onboarding, implementation and local-language support.










We operate from Hong Kong — our international headquarters — with offices across Asia Pacific, Europe and the Americas.
