Mouro Capital closes $400M Fund III to back fintech and AI infrastructure startups

London-based venture capital firm Mouro Capital has closed its third fund at $400 million, marking its largest fund to date and bringing total capital commitments across the firm to more than $1 billion since its launch in 2015.

  • Founded as the venture arm of Banco Santander and later spun out as an independent firm, Mouro Capital invests in startups focused on reshaping financial services through software, data and infrastructure. 
  • The firm has backed more than 30 companies, including iZettle, Kabbage, Creditas, Curve, Ripple, Tradeshift, Trulioo and Upgrade.
  • The new fund will focus on companies operating across financial infrastructure, payments, lending, insurance and compliance, with an emphasis on technologies modernising core financial systems. Key areas of interest include real-time payments, AI-enabled financial tools, programmable money and digital identity infrastructure.
  • Mouro Capital said it will continue investing at the infrastructure layer of financial services, where legacy systems are being replaced by software and automation. The firm views these segments as central to the next phase of fintech development as artificial intelligence lowers the cost of building and scaling financial products.
  • The investment strategy will remain global, covering Europe, the United States and Latin America. With teams based in London, Madrid and San Francisco, the firm tracks how financial products evolve across different markets, using this perspective to inform investment decisions and portfolio support.
