What believers are saying

  • The company now serves over 30 financial institutions and processes 100 million trades yearly.
  • Product expansion into pensions, ELTIFs, and derivatives widens wallet share across 2026.

What critics are saying

  • Upvest depends on partners like Qonto, SumUp, and CMC Markets for revenue concentration.
  • Germany and UK regulators can freeze launches if custody, reporting, or suitability fail.
  • A major trading outage or client insolvency would quickly destroy trust and trigger defections.

What makes Upvest unique

  • Upvest’s BaFin and FCA licenses let clients launch across Europe without rebuilding custody.
  • The June 2026 Qonto and March 2026 SumUp deals prove embedded investing demand.
  • Upvest’s true-ownership fractional-share structure avoids derivative wrappers and PRIIPs headaches.

Tomorrow lets retail investors back into its €15 Million Impact fund after two-year freeze.

Tomorrow lets retail investors back into its €15 Million Impact fund after two-year freeze. Hamburg-based sustainable banking app Tomorrow opened its in-house equity fund to new purchases on Wednesday, restoring a buy function that has been unavailable since the company moved its securities business to Berlin infrastructure provider lemon.markets in 2024. New customers can now open a securities account and buy into the fund for the first time, the two companies said. The Tomorrow Fund (ISIN: DE000A2QK5D4) held €15.41 million in assets at the end of December 2025, according to fund data published by Das Investment. It launched in June 2021 and is classified as an Article 9 product under the EU's Sustainable Finance Disclosure Regulation. Annual costs run to roughly 1.5%, made up of 1.2% in management and operating fees and 0.3% in transaction costs. Tomorrow says the portfolio holds more than 70 listed companies, from bicycle component makers to wind turbine specialists. Two Years From Migration to Buy Button lemon.markets took over investment brokerage, trading and custody for Tomorrow in 2024, replacing an arrangement that ran through Solaris SE, Baader Bank and DonauCapital. Solaris continues to handle the banking side. Tomorrow stopped securities account openings in its app on June 11, 2024, migrated existing custody accounts that August, and told customers investing would return in the fall. Holders could keep their shares through the switch but could not buy or sell. Wednesday's announcement does not address the gap between that timetable and the buy function arriving now. Tomorrow did not say how many of its customers hold the fund. The Tomorrow Fund is "now open to everyone who wants to invest in line with their values," Co-Founder and Co-CEO Inas Nureldin said.Co-Founder and Co-CEO Inas Nureldin [#highlighted-links#] A €15 Million Fund Inside a €2.2 Trillion Custody Group lemon.markets is no longer independent. Deutsche WertpapierService Bank completed its purchase of the firm on September 30, 2025, once BaFin cleared the deal, adding an API brokerage platform to a custodian holding €2.2 trillion in assets and processing securities transactions for about two thirds of German banks. lemon.markets dates the tie-up to August 2025 in its own materials. The two businesses kept separate names and sales operations after the deal closed. The Berlin firm has raised more than €28 million since 2020, including a €12 million round led by CommerzVentures. Its clients include Pleo, Holvi and Optio, and it has worked with BNP Paribas and Deutsche Bank on the brokerage-as-a-service product.lemon.markets Founder and Chief Executive Max Linden lemon.markets Founder and Chief Executive Max Linden described the platform as "a modular foundation that grows with partners like Tomorrow." German Infrastructure Rivals Chase Bigger Mandates What separates lemon.markets from its closest domestic competitor is mostly the size of the client. Upvest, founded in Berlin in 2017, processed more than 100 million orders in 2025 against 20 million a year earlier, and serves Revolut, N26, bunq and Santander's Openbank. IG Group signed Upvest to run stock and ETF trading for French customers, and CMC Markets uses the same provider for multi-currency stocks and ETFs in Germany. Upvest raised $125 million at a €640 million valuation in a round led by Sapphire Ventures and Tencent. Alpaca entered the market by buying UK provider WealthKernel and renaming it Alpaca Europe. Tomorrow, which says it has more than 100,000 customers and around 10,000 crowd investors, is a smaller account than the neobanks on Upvest's roster. Second Product Is an ETF Listed Since December Tomorrow customers can also buy the Inyova Impact Investing Active Equity Fund EUR UCITS ETF (ISIN: LU3075459852) from Wednesday. The actively managed fund carries a product cost of 0.95% and accumulates income. Inyova listed it on Deutsche Börse's Xetra in December 2025 and on the SIX Swiss Exchange in January 2026, where Inyova SICAV was the first new ETF issuer of the year. Tomorrow said further investment products will follow. Tomorrow does not hold a banking license of its own. Its transactions run through Solaris SE, which BaFin fined €500,000 in June 2025 for repeatedly breaching large exposure limits between January 2022 and March 2024.

Qonto partners with Upvest to enable businesses to put their idle cash to work with money market funds.

Qonto partners with Upvest to enable businesses to put their idle cash to work with money market funds. Julieta Varsano * Europe's leading business finance management solution Qonto is partnering with Upvest to add investment capabilities for SMEs across Europe * Through Upvest's API-first infrastructure, Qonto's business users will be able to earn yield with money market funds directly within the platform * The partnership brings access to selected capital markets investment products to hundreds of thousands of businesses Berlin, 8 June 2026 - European business finance platform Qonto today announces a partnership with Upvest, Europe's leading investment infrastructure provider, to launch a new in-app investing feature. Qonto's business users can now allocate surplus cash into highly competitive, euro-denominated money market funds from as little as €1. Germany, Qonto's largest market outside France, will be the first to benefit from this new offering, followed by a future market expansion across Europe. Money market funds are a natural fit for small and medium sized businesses looking to earn returns on working capital broadly in line with overnight deposit rates. The new feature is embedded into the Qonto experience, and can be accessed without leaving the platform or performing an additional KYB (Know Your Business) verification beyond the existing Qonto account verification. Additionally, the yield is shown transparently, net of all fees, directly inside the Qonto dashboard. Thus, businesses can now manage their accounts, track their spending, and handle their invoicing and bookkeeping, while putting their cash to work at the same time. For too long, the treasury tools available to large corporates have been out of reach for SMEs, even though collectively they hold billions in business accounts across Europe. Germany alone is home to more than 3.4 million SMEs, making it one of the most significant markets to address. This partnership is a step towards closing that gap. By giving its business users a simple and accessible way to earn returns on surplus funds, Qonto takes another step towards becoming the all-in-one financial home for European businesses, helping them not only manage their money, but grow it. Behind the scenes, Upvest's investment infrastructure handles order execution and settlement, custody, regulatory reporting, and tax processing, reducing operational complexity and enabling Qonto to focus on delivering a best-in-class experience for its users. "We built Qonto to give SMEs a smarter way to manage their finances. Every feature we build comes back to the same question: what do our customers actually need to run their business more effectively? The answer was clear as many SMEs have idle cash and they want to use it in a way that is working for them and supporting their growth. Partnering with Upvest thus is a natural next step as it brings investment capabilities directly into the Qonto platform and makes investing in money market funds as simple as transferring money" Malte Dous Managing Director Central Europe "We are proud to partner with Qonto to bring investment capabilities to some of Europe's most dynamic businesses. Powered by Upvest's Investment API, Qonto can now offer its business users a seamless, low-friction way to grow their cash, while we handle all the complexity behind the scenes. This partnership is a strong example of how modern investment infrastructure can make capital markets genuinely accessible at scale." Martin Kassing CEO and co-founder of Upvest About Qonto Qonto is Europe's leading finance management solution serving over 600,000 SMEs and freelancers across 8 countries. Launched in 2017 by Alexandre Prot and Steve Anavi, Qonto combines business banking with powerful financial tools including invoicing, bookkeeping, and spend management - all in one seamless solution.

SumUp partners Upvest to launch in-app investments.

SumUp partners Upvest to launch in-app investments. By vriti gothi. SumUp has partnered with Upvest to introduce in-app investment capabilities for small businesses and merchants, marking a further step in the convergence of payments, banking, and wealth management within FinTech platforms. The new feature enables merchants to invest surplus balances into fractional money market funds directly within the SumUp app, with entry points starting at €1. Initially launching in Germany, the offering is expected to expand across Europe and the UK, extending capital markets access to SMEs already using SumUp's business banking services. The move reflects a broader industry shift towards embedded finance models that integrate investment products into everyday financial workflows. By incorporating money market funds typically composed of short-term, high-quality debt instruments SumUp is positioning the feature as a low-risk, liquid option for businesses seeking returns on idle cash without moving funds خارج its core platform. Upvest's API-first investment infrastructure underpins the offering, handling trade execution, custody, settlement, and regulatory reporting. This allows SumUp to integrate investment functionality without building capital markets infrastructure in-house, reducing operational complexity while accelerating time to market. Felix Lamouroux, SVP Global Banking at SumUp, said the initiative addresses a common challenge among small businesses managing liquidity. "Too often this money sits idle in deposits, when it could be earning interest through investments. By bringing simple, low-risk investment options onto the SumUp platform, merchants can build wealth on their existing deposits within a familiar environment," he said. Martin Kassing, CEO and co-founder of Upvest, added that the partnership demonstrates how investment infrastructure can be embedded at scale. "This partnership shows how modern investment infrastructure can make capital markets investing accessible and operationally simple," he said. Strategically, the launch underscores SumUp's ambition to evolve from a payments provider into a broader financial services platform for SMEs. For the sector, it highlights increasing competition among FinTechs to capture a larger share of customer financial activity by embedding savings and investment tools alongside core payment and banking services. As interest rates and cash management remain key concerns for small businesses, the integration of yield-generating products into operational accounts could reshape how SMEs manage working capital - blurring the lines between treasury management and everyday business banking.

Why are SumUp and Upvest backing embedded investing?

Why are SumUp and Upvest backing embedded investing? March 25, 2026 SumUp is partnering with Upvest to let merchants invest idle cash via in-app money market funds, turning everyday banking into an investment platform Global fintech SumUp has shared a new integrated investment feature that lets small businesses earn on their idle deposits - showing just how its platform has grown from payments to full-spectrum financial management. The company is partnering with Berlin-based Upvest to deliver the service through an API-first model, enabling SumUp's four million merchants to invest directly in euro-denominated money market funds starting with as little as €1 (US$1.16). Initially launching in Germany this month, the functionality will roll out across Europe and the UK in the coming months. The goal, SumUp says, is to give merchants an accessible way to grow surplus cash without complexity or exposure to high-risk investments. Embedded wealth management to support small businesses. By adding investment options to its existing business banking suite, SumUp is blurring traditional boundaries between payments, banking and investment. The move reflects a broader trend in embedded finance - empowering SMEs to manage all financial operations within one digital platform. The new investing feature sits natively within the SumUp app, where merchants already manage day-to-day transactions, card payments and cash advances. Users can now allocate part of their available balance into money market funds - low-risk instruments designed to preserve capital and provide liquidity - without leaving the platform. Behind the scenes, Upvest's investment API powers the full stack of infrastructure, from order execution and custody to regulatory reporting and tax processing. "Small businesses are under constant pressure to set money aside for a rainy day. Yet too often this money sits idle in deposits, when it could be earning interest through investments," says Felix Lamouroux, SVP Global Banking at SumUp. "That's why Fintech Magazine is thrilled to be partnering with Upvest to help build investing into the everyday banking experience for small business owners. "By bringing simple, low-risk investment options onto the SumUp platform, merchants can build wealth on their existing deposits all within a trusted, familiar environment." This emphasises how, for SumUp, the partnership is rooted in a clear mission: to help small businesses build financial resilience and grow wealth over time. The approach not only modernises SumUp's banking ecosystem but also gives SMEs access to opportunities that were once exclusive to larger corporations or specialist financial institutions. Ensuring innovation is infrastructure-first. Upvest's involvement further drives home how API-driven investment infrastructure is transforming capital markets access. Its platform handles the operational and regulatory complexities - execution, settlement, custody and compliance - behind the scenes, freeing partners like SumUp to focus on user experience. Martin Kassing, Co-Founder and CEO of Upvest, says: "Fintech Magazine is proud to be working with SumUp to seamlessly integrate investing capabilities into everyday business banking. "Powered by Upvest's Investment API, SumUp can now offer a best-in-class investment proposition for merchants to grow their wealth. "This partnership shows how modern investment infrastructure can make capital markets investing accessible and operationally simple at scale." Upvest already powers investment features for several high-growth fintechs, including Revolut, N26, Webull and Raisin. Its collaboration with SumUp shows how the company's infrastructure model can extend beyond consumer finance and into the realm of small business banking. Company portals.
