London-based fintech firm SumUp is gearing up for a potential initial public offering (IPO) on the London Stock Exchange. The company, known for its small business payment solutions like card readers and digital invoicing, has started talks with major banks to arrange the listing, sources familiar with the matter told Reuters on April 15, 2026.
Founded in 2011, SumUp has grown rapidly across Europe and beyond. It serves over 4 million merchants in 36 countries, processing more than €100 billion ($108 billion) in transactions last year—a 20% jump from 2024. With 2,500 employees, SumUp competes with giants like Square (now Block) and PayPal by offering affordable tools for SMEs. Its revenue hit €1.2 billion in 2025, up 15% year-over-year, despite economic headwinds.
The IPO buzz comes amid a fintech revival. London’s market, recovering from 2022 slumps, saw Wise list successfully in 2021 and Revolut eye a valuation over $45 billion. SumUp, last valued at $8.5 billion in a 2022 funding round, could raise $500 million to $1 billion, per bankers’ estimates. This move supports CEO Francisco Simó’s expansion plans, including AI-driven payments and entry into India and Southeast Asia.
Regulatory scrutiny on data privacy and competition from Adyen. Yet, SumUp’s profitability—EBITDA-positive since 2023—makes it attractive. A London IPO could boost UK fintech’s profile post-Brexit, drawing investors amid US market volatility.
