RetailBook, a UK-based FinTech platform that empowers retail investors to participate in primary capital market deals on equal terms with institutions, has announced a £4.5m funding round.
The round was led by Augmentum Fintech, one of Europe’s leading FinTech-focused venture capital firms. Existing investors Peel Hunt, Jefferies, Rothschild & Co, and Hargreaves Lansdown also joined the round to support RetailBook’s next phase of growth.
RetailBook enables broader participation in capital markets by bridging the gap between retail and institutional investors during equity and debt transactions. The platform has gained momentum in recent years as regulators and policymakers continue to encourage wider market participation from the public.
With the new funding, RetailBook plans to extend its offering across additional asset classes, build on its technology infrastructure, and strengthen relationships with retail brokerage platforms. The firm also intends to broaden the capabilities of its platform to enhance retail access to fixed income opportunities.
Earlier this year, RetailBook bolstered its team by bringing on board the former PrimaryBid Capital Markets Team, a move that significantly deepened its expertise in retail engagement. The expanded team brings a track record of more than 400 executed deals across UK and European markets, across both equity and debt offerings.
RetailBook co-CEO James Deal said, “We are delighted to welcome Augmentum and look forward to utilising their extensive expertise and network in the fintech sector. Our goal remains the delivery of comprehensive public inclusion. Retail investors are a crucial component of vibrant capital markets and we are excited by the pipeline of truly exceptional companies that are considering London as their listing venue.”
Co-CEO Aaqib Mirza added, “This fundraise allows us to execute our growth strategy and continue our journey of retail investor empowerment. Strategic expansion through the hire of a team with unique expertise and an unrivalled track-record has delivered exactly what we forecast, including widening our product set to include a new fixed income service that has already raised record amounts from retail investors.”
Augmentum Fintech CEO Tim Levene, who will join the RetailBook board, said, “We have had a relationship with the RetailBook team for some time, and their work to democratise investment access directly reflects Augmentum’s core mantra.
“With recent market reforms focused on enhancing UK market liquidity and the government’s emphasis on unlocking diverse capital pools, RetailBook is poised to play a crucial role. Their excellent team, strong network, and best-in-class solution will enable them to become the key channel for retail participation in public markets.”
