Plum selects Upvest as its investment infrastructure provider in the UK, extending its existing European partnership

• Starting with a launch of investment funds, followed by stocks and ETFs, Plum will then migrate its existing funds investment business in the UK to Upvest as a next stage
• By deepening its partnership that already covers continental Europe, Plum is able to rely on modern infrastructure that scales seamlessly across markets, asset types, and use cases
• Consolidating onto one platform enables Plum to grow with confidence on a cloud-native Investment API, built to support high trading volumes

Berlin / London, 26. August 2026 - Plum, the smart money app that helps millions of people save and invest, has selected Upvest, Europe’s leading investment infrastructure provider, as the platform powering its investment functionality in the UK.

This builds on a partnership dating back to 2023, during which Upvest has powered Plum's investment business in continental Europe. Extending that relationship to the UK allows Plum to use the same state-of-the-art Investment API to deliver modern investment experiences across its markets. Plum has supported millions of end users in Europe to do more with their money, with more than £10 billion set aside via the app. 

As Plum scaled, its investment operations across markets involved several different providers working together across the value chain. Under the new arrangement, Upvest replaces a multi-provider structure with a streamlined and flexible brokerage and custodian structure. The migration is designed to give Plum a simpler operating model, fewer integration points to manage, and reduced operational complexity as it continues to grow its user base.

Plum's migration marks another major milestone for Upvest in the UK, proof that its infrastructure can support a consolidated model at real scale. As fintechs and financial institutions move away from complex multi-vendor setups or legacy infrastructure, more are turning to a single partner that can scale reliably, both within the UK and across Europe. Upvest delivers on that promise, speeding up innovation with real-time data, daily product releases, and over 99% automation of middle- and back-office processes across brokerage, settlement, and custody.

With its modular and API-first architecture, Upvest empowers Plum to scale investment products that are intuitive and localised, with modern use cases such as fractional investing from £1 and automated recurring investments.

"Having seen the positive impact of our collaboration in EU markets, it was a natural step for Plum to partner with Upvest for investment services to our UK customers as well. We want to help our users build wealth over the long-term, and investment services are central to this ambition. We look forward to working with Upvest to make investing more accessible."

"Plum has trusted us to power its European business since 2023, and we're proud they've chosen to bring that same partnership to their home market. Consolidating onto one platform gives Plum a more resilient foundation, and as they enter their next stage of growth, our infrastructure is designed to scale with them."
