About Aaron Tsai

Aaron Tsai (蔡逸群), Founder and Chief Capitalist at MAS Capital (名资) and MASFi (名资链) and HashBrownSwap(薯饼交易所), is no stranger to entrepreneurial ventures and experiences. While he is known to have pioneered some innovative platforms for investing in securities today, it’s perhaps more interesting to learn about his journey--failures and challenges included--since he started in the technology scene in the early 1990s.

Tsai attended the NYU Leonard N. Stern School of Business from 1988 to 1990, and it was during the dot-com boom when he entered the tech scene by launching two companies in Silicon Valley: American Multimedia, Inc., and Multi Access Systems, Inc. or “MAS”. Tsai also acquired notebook computer company ACOM through reverse-merger via Aimex International Corp., a public shell company.

Today he is spear-heading in DeFi through HashBrownSwap (HBS), an open, cross-chain DeFi platform with a next generation exchange, designed for everyone.
