European investment technology provider Huddlestock and capital markets software developer Devexperts announced today (Wednesday) they have built a white-label Investment-as-a-Service app for the European market, with the product set to debut through German broker GIGA Broker's upcoming platform launch.

The app is based on DXtrade, Devexperts' multi-asset trading platform , and is designed to let financial firms offer investment services to retail clients under Huddlestock's BaFin-regulated infrastructure, which covers custody, brokerage, KYC, payments, and reporting, the companies said.
"Together with Huddlestock, we have built a tailored solution based on our flagship multi-asset trading platform, DXtrade, that meets Huddlestock's clients' needs today, while giving them the flexibility to adapt and scale with the market," said Heetesh Rawal, Vice President at Devexperts.
Three Modes, One Regulatory Shell
The app comes in three configurations, according to the companies. Firms can deploy a simplified interface aimed at entry-level investors, a more feature-rich environment for experienced users, or they can connect their own front-end via a bring-your-own-frontend option. All three options run on Huddlestock's shared regulatory infrastructure.

A central feature of the arrangement, from Huddlestock's perspective, is what the company calls a liability umbrella model, which it says allows clients to offer regulated investment services in Europe without holding their own financial license. Through European passporting rules, firms joining the platform can operate across multiple EU jurisdictions after initially going live in Germany, the companies said. Huddlestock described the approach as "Germany-first, Europe-scale."
"By combining our regulatory infrastructure with Devexperts' proven technology, we enable our customers to launch and scale investment offerings more efficiently, while staying fully compliant," Leif Arnold Thomas, CEO of Huddlestock, said in a statement.
White-Label Infrastructure Gains Ground in European Markets
The Huddlestock-Devexperts tie-up enters a space that has seen several providers build similar plug-in investment infrastructure for firms that lack the resources or regulatory capacity to build their own brokerage stack. Devexperts has previously delivered white-label versions of DXtrade to European brokers, including WH SelfInvest's Freestoxx platform in 2022, which targeted the DACH region and offered commission-free US stock trading. That arrangement used a white-label SaaS version of DXtrade equipped with advanced charting tools and multi-monitor support.
Berlin-based Upvest, which raised $125 million in fresh funding earlier this year at a €640 million valuation, occupies a comparable position in European investment infrastructure. Upvest powers the investment back-ends of several European banks and fintechs, providing order processing and custody services, and has been expanding across the continent. Like the Huddlestock offering, it targets firms that want to embed investment products without building the underlying infrastructure themselves.
Solarisbank, the Berlin-based banking-as-a-service provider licensed by BaFin, has also moved into investment infrastructure in recent years, offering white-label brokerage and custody as part of its broader embedded finance stack for fintechs and neobanks.
Devexperts has been steadily broadening DXtrade's third-party ecosystem. Earlier this month, the company added Gold-i's Visual Edge risk management tool to the platform, and separately pushed a round of interface changes covering both the web terminal and broker back-end tools.
Regulatory Complexity Drives Demand for Outsourced Infrastructure
The companies framed the launch against a backdrop of escalating regulatory change in Europe. Huddlestock cited ongoing developments across Payment for Order Flow rules, MiFID II/MiFIR, GDPR, the Anti-Money Laundering Authority framework, operational resilience requirements, AI governance, and crypto asset regulation as factors increasing demand for firms that can manage compliance on behalf of their clients.
The growing complexity of embedded finance in Europe has drawn a widening set of market participants beyond traditional brokers, including insurers, media platforms, and asset managers without direct retail distribution channels. Huddlestock said its solution is intended to serve all of these groups, as well as international firms looking for an entry point into EU markets.
"Huddlestock's IaaS platform brings together regulatory strength, a modular architecture, and broad integration capabilities, enabling partners to launch and scale investment services efficiently while maintaining long-term strategic flexibility," Thomas added.
GIGA Broker First, Broader Rollout Planned
GIGA Broker, a German broker, is the first firm to deploy the product, with its launch described as imminent. Huddlestock and Devexperts said the white-label app will be presented publicly at FIBE 2026, a European fintech conference drawing more than 2,000 attendees, before being made available to other firms across the continent.
Devexperts, founded in 2002 and headquartered in Ireland, employs more than 800 engineers across offices in the US, Germany, Portugal, Bulgaria, Singapore, Turkey, and Georgia. The company has added a series of integrations and product updates to DXtrade in recent months as competition among white-label platform providers tightens across European retail markets. Huddlestock, which also owns Visigon, a Nordic-based capital markets consulting firm, operates its regulated entity, Huddlestock GmbH, under a BaFin license.
