Chiappinelli to lead international commercial strategy and drive global market expansion
London / New York, 2 June 2026: BMLL, the leading independent provider of continually engineered, harmonised, historical Level 3, 2 and 1 data and analytics for Capital Markets, spanning global equities, ETFs, futures and US equity options, today announced the appointment of Michael Chiappinelli as Chief Revenue Officer. Based in the USA, he will lead the company’s international commercial strategy and revenue organisation, accelerating global market expansion and deepening institutional client engagement. Michael will report to Paul Humphrey, CEO of BMLL, and join its executive management team.
Chiappinelli’s appointment is a key part of BMLL's growth strategy, following the recent acquisition by Nordic Capital in October 2025. In his role, the global sales function will report directly to him, as he focuses on scaling BMLL’s global footprint, capitalising on the demand for harmonised, multi-asset historical data, and reinforcing the company's position as the leading provider of advanced market data and analytics solutions.
Chiappinelli brings over 25 years of institutional sales leadership experience in financial market data, advanced analytics, algorithmic trading technology, and enterprise SaaS, having built and scaled high-performing global sales organisations serving premier hedge funds, asset managers, investment banks, and private equity firms. Prior to joining BMLL, he served as Global Head of Sales & Account Management for the Investors vertical at Similarweb and as Managing Director and Head of Sales at SESAMm. He also held senior leadership roles at Acuris, Cowen, and Refinitiv. He has successfully led commercial organisations across both private equity-backed growth companies and established global financial information providers, helping institutional clients leverage sophisticated data, market structure insights and AI-driven analytics to enhance investment, trading and quantitative research workflows.
Paul Humphrey, CEO, BMLL, said: “I am delighted to welcome Mike to the team. His appointment is a crucial step in our global expansion following the acquisition from Nordic Capital. Bringing him on board will be instrumental to delivering on that mission as we accelerate our global footprint. In a market where the demand for actionable intelligence has never been greater, AI continues to fuel unprecedented institutional demand for the highest quality content, the artifact of first-class engineering capabilities. Michael’s deep expertise in leading high-performing global sales organisations will be instrumental in helping us capitalise on this momentum. He joins us at an incredibly exciting time, and his leadership will ensure we continue to empower market participants globally with the harmonised, multi-asset data and analytics they need to innovate and win."
Michael Chiappinelli, Chief Revenue Officer, BMLL, added: "I am incredibly excited to join the firm at such a defining time. BMLL has built an enviable reputation for delivering the industry's highest quality historical data products, and there is a clear, growing appetite among institutional participants for this depth of insight. Advancements in AI play to our core strength at BMLL and I am looking forward to capitalising on this. I look forward to working with the team to scale our presence globally and help our clients leverage unique data, analytics and advanced workflows to truly optimise their investment and trading strategies."
