LiquidityBook taps ex-JonesTrading Sayant Chatterjee as COO
The hire comes on the heels of a successful minority funding round in which Primus Capital Partners took a stake in the company

LiquidityBook has appointed Sayant Chatterjee as Chief Operating Officer to help scale LiquidityBook’s sell-side product suite and deepen its commitment to this aspect of its business.
Based in the firm’s New York office, Mr. Chatterjee is an industry veteran with 20 years of experience working with the broker-dealer community to design and deliver complex global solutions.
Sayant Chatterjee joins LiquidityBook from JonesTrading, where he was Chief Information Officer for over seven years and spearheaded product development initiatives to create industry-leading trading services across all of Jones’ business lines.
Prior to that, Mr. Chatterjee was at Fidessa for nearly 13 years and worked on all aspects of the business, including implementation, product management, and strategy, as well as expanding the company’s presence in Asia.
Sean Sullivan, Chief Revenue Officer at LiquidityBook, commented: “Adding Sayant to the team is emblematic of our ongoing commitment to the sell side. Broker-dealers are looking for more efficient, cost-effective systems in a very competitive space and amid shrinking margins.
“As such, they require an OMS with the latest in SaaS technology and a transparent, intuitive business model. Sayant has been at the forefront of this transition away from legacy products and business practices and will immediately make an impact on our ongoing efforts. His wealth of industry experience and deep engagement with the sell-side community are exceptional, and we look forward to bringing him aboard.”
Sayant Chatterjee, Chief Operating Officer at LiquidityBook, said: “Whether at a broker-dealer or on the vendor side, I have spent my career learning about the unique needs of and challenges faced by sell-side firms.
“As a longtime client of LiquidityBook, I have a firsthand knowledge of their great operating model, ease of configuration and deployment and ability to keep up with the ever-shifting needs of the broker community. Joining their team represents a rare opportunity to help deliver a truly transformative solution backed by client service and technology teams that are second to none. I could not be more excited to get started.”
The firm has recently appointed Frank Kost as Head of Sell-Side Business Development, North America. He served as Director of Business Development at Axos Clearing. He has also worked at Sungard, Aegis Capital and Bloomberg and has a strong knowledge of the sell-side OMS space. This makes him an ideal fit for the position at LiquidityBook.
Both hires come on the heels of a successful minority funding round in which Primus Capital Partners took a stake in the company.
LiquidityBook has been making a serious push for business development over the last few months with its LBX system and it had reported record revenues over the last year, a year when most of the trading firms were struggling with falling revenues due to the pandemic.
LiquidityBook handles order management, FIX connectivity, portfolio management, and trade processing for a variety of trading companies and is respected as a leader in SaaS solutions for the modern trading desk.
