getquin is a Berlin-based digital wealth platform founded in 2020 with a clear mission: give retail investors a single place to see and understand everything they own. Today, more than 500,000 users across Europe track over €20 billion in assets on the platform - stocks, ETFs, crypto, dividends, alternative investments, and more.
The platform combines real-time portfolio analytics with community features, a dividend calendar, X-ray fund analysis, and AI-powered insights. Users can benchmark performance, model scenarios, and share portfolios with other investors. Built in Germany, getquin is now actively expanding across Europe - with Spain as their most recent milestone.
Client: getquin
Headquarters: Berlin, Germany
Sector: Fintech · Retail Wealth · Portfolio Tracking
Flanks use case: Multi-custodian portfolio aggregation · European markets
Target users: Retail investors managing portfolios across multiple European brokers
Key result: 50+ custodians connected across Europe
The challenge
European retail investors rarely keep everything in one place. A typical getquin user might hold ETFs on DEGIRO, individual equities on XTB, a pension at their bank, and a position on Trade Republic - all at once, across different institutions and countries. This fragmentation is structural and growing.
To deliver on their core promise - one place for everything you own - getquin needed a way to pull position data from all those custodians automatically. Building and maintaining direct connections to institutions across multiple European markets is a resource-intensive challenge that pulls product and engineering focus away from the core platform: each institution has its own data structure model, authentication flow, and data format. Also, by connecting directly to custodians, and automatically extracting portfolio data in a standardised way, getquin can focus on the platform and delivering first-class services to their clients.
The solution: Flanks as data aggregation infrastructure
getquin integrated Flanks Aggregation to connect users’ brokerage and custodian accounts across European markets. Flanks acts as the invisible data layer: when a user links a broker account, Flanks handles authentication, retrieves positions and transaction history, normalises the data into a consistent schema, and delivers it to getquin’s platform standadrised and in real time.
The integration is invisible to the end user. A user in Spain links their CaixaBank or DEGIRO account; a user in Germany links their Trade Republic or Trading212 account. In both cases, their portfolio updates automatically. No manual steps, no stale numbers.
Custodians now connected for Getquin users - Spain as the latest example of European coverage:
- DEGIRO
- XTB
- InteractiveBrokers
- MyInvestors
- Bankinter
- Trading212
- CaixaBank
- Unicaja

Results
With Flanks powering the aggregation layer, getquin users can link their custodian accounts and see their complete portfolio - positions, performance, and history - updated automatically. No manual data imports needed for connected brokers.
For getquin, this means their product delivers its core promise in every European market, and North America where they operate, without diverting engineering resource to infrastructure.
“ Partnering with Flanks allows us to scale efficiently across our key markets, while giving our customers access to extensive aggregation options.” - Raphael, Co-founder, getquin
