Anthony is the founder of GreenKey (GK) which converts complex, mission critical audio and text into seamless data structures to automate and analyze real time human tasks.
Tassone is the inventor of the patent-pending "decline ratio" crossing algorithm, which is part of The Block Pool technology and helps eliminate no obligation quoting that plagues OTC indicative markets. The crossing algorithm sorts and ranks participants by how likely they are to accept the deal price they are currently quoting by referencing their historical decline ratio. He is also the inventor of the patented "concurrent push-to-talk" features of the trader voice box software - allowing one user to communicate with dozens of other users concurrently.
Before joining GreenKey, Tassone was Director of Volatility Trading for Buttonwood Group Trading. He was also a vice president of Algorithmic Trading Solutions for RTS Realtime Systems Group in London and director of product development for the U.S. Futures Exchange.
