What Maystreet does
MayStreet is a New York–headquartered fintech firm that built a market data infrastructure platform focused on delivering real-time and historical capital market data, with a domain specialization in the derivatives industry. Founded in 2012, the company's technology provided low-latency and consolidated data feeds, tick-by-tick historical archives, and normalized data formats designed for electronic trading, algorithmic and high-frequency strategies, regulatory surveillance, and back-testing. Its primary customer segments were trading firms (electronic, algo, and HFT desks), financial regulators requiring complete market coverage and audit trails, and financial institutions needing risk, analytics, and compliance data.
The company raised approximately $31 million in venture funding, including a $21 million Series 2 in mid-2020 led by Credit Suisse NEXT Investors with Tribeca Early Stage Partners, and a $10 million round in early 2021 from CIBC Innovation Banking. In 2022, MayStreet was acquired by LSEG (London Stock Exchange Group) and integrated into LSEG's Data & Analytics division, where its technology now sits alongside LSEG's broader real-time data franchise spanning 575+ venues and processing 100-200 billion messages per trading day.
MayStreet operates as a B2B subscription-based market data provider, with revenue derived from licensing real-time and historical data feeds to trading firms, regulators, and financial institutions. Since the LSEG acquisition, it no longer operates as an independent commercial entity; its go-to-market now flows through LSEG's enterprise sales motion, LSEG Workspace, and industry-standard APIs targeting global financial market participants. Executive leadership includes Dave Breau (Chief Strategy Officer & General Counsel) and Naftali Cohen (Chief Revenue Officer).
