AI in finance in Berlin

Berlin has no stock exchange and no central bank head office, so its finance sector grew around banks, insurers and, over the last decade, fintechs. Berlin Partner for Business and Technology counts 652 financial services companies with about 13,500 employees in the city, and 28 central banks and credit institutions have a presence there. More than a third of German fintechs are based in Berlin, among them the neobank N26 and the neobroker Trade Republic, as the fintech in Berlin page explains.

That shapes how AI shows up. A Berlin fintech has no branch network and few phone lines, so the first AI a customer meets is usually in the app: a chat that answers account questions, a check that stops a suspicious card payment, a model that sorts transactions into categories. Frankfurt's large banks start AI projects in back offices and research teams, and Berlin's app providers start in the customer chat.

N26 holds a full EU banking license and serves customers across Europe from Berlin. It built an AI assistant for customer service on the open-source framework Rasa and ran it in its own secure cloud environment. According to Rasa's case study, the assistant works in five languages in the mobile and web app, handles tasks such as reports of lost or stolen cards, and took over 20 percent of customer service requests soon after going live, with 30 percent as the next target.

A chatbot like this is not a high-risk system under the EU AI Act, but the customer must be told that they are talking to an AI. BaFin names customer chatbots as one of the AI uses it supervises at banks under the German act implementing the AI Act. The heavier duties start once a neobank or a buy-now-pay-later provider uses a model to score the creditworthiness of a private customer: that use is high-risk under Annex III of the AI Act, with human oversight and a fundamental rights assessment before first use.

The Berlin Institute for the Foundations of Learning and Data (BIFOLD) came out of the 2019 merger of two national AI competence centers, the Berlin Big Data Center and the Berlin Center for Machine Learning. It is based at TU Berlin, with Charité Universitätsmedizin Berlin as institutional partner, and it is one of Germany's six national AI centers with permanent funding from the State of Berlin and the federal research ministry. Its work on data management and scalable machine learning is the part closest to finance, where models run on very large transaction and market data sets.

ai.berlin describes itself as "the central platform for artificial intelligence in the capital region". It connects business, research and the public sector and runs the ai.berlin hub at CIC Berlin, a space for events, workshops, office hours and networking. For a finance team looking for AI partners in the city, the directory on ai.berlin is a practical first stop.

A Berlin fintech follows the same rules as one in Frankfurt or Munich. BaFin supervises from Bonn and Frankfurt and has no Berlin office. Under the German act implementing the AI Act, BaFin also supervises AI that banks and payment firms use in direct connection with regulated business, while AI outside regulated business, such as recruiting software, falls to the Bundesnetzagentur.

Many Berlin fintechs rely on banking-as-a-service platforms and cloud providers, and every AI model they buy runs on someone else's infrastructure. Under DORA, each of those contracts belongs in the register of ICT third-party arrangements, and a model that supports a critical function needs exit plans and audit rights in the contract. The EU AI Act in financial services page lists the AI duties by role.

Finance Loop is the meeting place for product managers, data scientists, compliance people and founders who build AI into Berlin's banks, neobanks and brokers. It connects the finance, IT and AI communities in Germany, Austria and Switzerland and holds events in Berlin as well as in Frankfurt, Munich and Hamburg.

Finance Loop supported the German Blockchain & AI Week 2025 in Berlin, whose program had a talk titled "AI - The Future of Everything", a session on what drives AI compliance and a "Germany Insights" slot with DWS Group. Claude Hacker House, the hands-on Claude series that Finance Loop supports with Finteda and Frankfurt Data Science, names Berlin among its cities. The Bitcoin seminar in Berlin is the Finance Loop format for investors who want to understand bitcoin as an asset class.

Berlin hosts several general AI conferences and summits, and AI in finance appears there as one track among many. The German Blockchain & AI Week, which Finance Loop supported, put AI and blockchain on one program. Finance Loop lists the Berlin dates it runs or supports in the calendar above and on the events page.

The ai.berlin hub is the physical space of ai.berlin at CIC Berlin. It hosts events, workshops, office hours and networking for Berlin's AI ecosystem, and ai.berlin runs a directory of companies and institutes in the region.

BIFOLD at TU Berlin, with Charité as partner, is the city's national AI center, with funding of 22 million euros a year shared by the federal government and the State of Berlin. Its fields reach from data management to machine learning in medicine, industry and e-commerce.

ai.berlin announces events at its hub, and Finance Loop holds its Berlin events with people from banks, fintechs and IT. For AI meetups with a finance focus, check the calendar on this page and the Finance Loop events page.
