This article covers LemonEdge, a fintech startup, completing a £15.8m series A funding round to speed product development and expand its fund accounting platform across the US and Europe. The development aims to fund hires, product roadmap delivery and go-to-market activity and targets private equity firms, fund administrators and large family offices that require modernised, auditable fund accounting and reporting.
LemonEdge, a fintech startup, has completed a £15.8m series A funding round to speed product development and expand its fund accounting platform across the US and Europe — a push the company says is aimed at tackling legacy systems that many private market firms still rely on. The round will bankroll hires, product roadmap delivery and go-to-market activity over the next 12 months.
Why it matters
Private markets are growing quickly and bring accounting and operational complexity that many legacy systems struggle to handle. LemonEdge positions itself as a single system of record for fund accounting and operations, claiming to move previously offline processes into automated, auditable workflows. If it delivers, that could reduce audit friction and speed reporting for private equity firms, fund administrators and large family offices managing very large pools of capital.
The company cites forecasts for rapid growth in private market assets, underscoring why vendors that modernise back-office infrastructure are increasingly relevant to institutional clients.
Inside the product
LemonEdge is presented as a fund accounting and operations system built to handle the "complexity private markets carry today." The platform is designed to centralise bookkeeping, investor reporting and operational controls in a single environment with automated processes and governance. The vendor says the roadmap moves towards broader operational intelligence across the fund lifecycle and includes native AI-driven reporting and analytics capabilities.
Target customers are private equity firms, fund administrators and family offices. The company also highlights that its clients collectively oversee very large asset pools, positioning LemonEdge as infrastructure for organisations that need auditable data and faster close cycles.
Who are the investors?
Blackstone Innovations Investments, the early-stage arm of Blackstone, led the £15.8m series A. BNY (NYSE: BNY) participated in the round, alongside long-time investor Sidekick Partners. The fresh capital brings LemonEdge's total raised to date to more than $30m.
Stevi Petrelli, Senior Managing Director, Head of Blackstone Innovations Investments, said:
Finance leaders choose accounting platforms that shorten close cycles, reduce audit risk and improve data insights. LemonEdge has built a trusted system of record for private markets, and embedded native AI capabilities to drive modern investor reporting and analytics. We are delighted to continue to support their growth.
Christine Waldron, Global Head of Fund & Investor Solutions, Asset Servicing at BNY, said:
Many of the firms we serve have requirements that legacy systems can no longer support, from new fund types to the safe adoption of emerging technologies. Both depend on one system of record where the data is governed, auditable and accurate. LemonEdge is among the platforms purpose-built to address these challenges, and we look forward to collaborating with a team that shares our commitment to solving the complex problems our clients face.

Founder perspective
LemonEdge has strengthened its senior team ahead of the expansion, appointing New York-based David T. O'Malley as Chief Executive Officer and Board Chair. O'Malley joins from Numerated Growth Technology, where he led international expansion and commercial strategy and oversaw its sale to Moody's Analytics. Katharine Briggs has been named Chief Growth Officer to lead go-to-market, delivery and client expansion across the US and EMEA.
David T. O'Malley, CEO of LemonEdge, said:
LemonEdge was built to simplify the complexity of the rapidly scaling private markets space, with global private market AUM forecast to reach $26.7tn by 2030. Legacy systems froze, and, as a result, many of the most sophisticated private market firms in the world are being held back by tools that were not designed for the complexity they face today. With this new funding, we plan to continue to address these major gaps and accelerate growth over the next 12 months, by bringing on a significant number of new clients and rapidly deploying our 2026 and 2027 innovation roadmap.
The bigger picture
The deal underlines ongoing investor interest in tools that modernise finance and operations for private markets. Startups that can combine accounting rigour, governance and faster reporting are increasingly attractive to institutional clients seeking to reduce manual processes and audit risk.
For UK and European fund managers and administrators, the arrival of better-integrated fund accounting platforms could change vendor selection and outsourcing strategies, particularly as firms pursue more complex fund structures and demand real-time investor reporting.
The funding and leadership hires also reflect cross-Atlantic competition for private markets infrastructure: US and European firms are both suppliers and customers in this space, and the success of platforms such as LemonEdge will hinge on adoption by regional institutional clients and administrators.
