Solaris adds instant-access savings account to ADAC credit card range.

Solaris adds instant-access savings account to ADAC credit card range. Solaris, the Berlin-headquartered Banking-as-a-Service provider, has added an instant-access savings account to the ADAC credit card portfolio, extending a partnership that has grown steadily since Solaris took on the programme. The product, known in Germany as a Tagesgeldkonto, follows a soft launch in September that made it available to 50,000 ADAC cardholders ahead of the full portfolio rollout. The account sits alongside the existing credit card account and can be opened digitally in a few steps. Onboarding requires IBAN linking and two-factor authentication. Deposits and withdrawals are processed either via the ADAC credit card account or a designated reference account, and deposited funds remain available daily. At launch, new customers receive a promotional interest rate of 3.5% per annum for the first three months. After that, a variable standard rate of 1.5% per annum applies to balances up to 100,000 euros. Interest accrues monthly and can be tracked daily through the ADAC credit card app and online banking portal. Steffen Jentsch, chief executive of Solaris, said the savings product was the "next logical step" in the partnership, with a stated aim of continuously expanding digital services for ADAC's large membership base. Joost Greve, managing director of ADAC Finanzdienste GmbH, pointed to simple digital processes and security standards as the product's defining priorities. Expanding the embedded product suite. The savings account is not the only feature added to the ADAC card this year. Since May, cardholders have had access to a function called EuroAbruf, which allows customers to transfer up to 5,000 euros from their available credit limit directly to a personal bank account via SEPA Instant Credit Transfer. The process is fully self-service and subject to risk and authorisation checks. According to a survey cited by Solaris, 90.3% of participating cardholders said they were very satisfied with the additional card features, though the methodology and sample size were not disclosed. The two additions together represent a pattern familiar in embedded finance: a card product used as a distribution anchor, with savings, credit access and payments layered progressively on top. This approach deepens the cardholder relationship and increases product revenue per user without requiring a full banking app relaunch. Market and regulatory context. Solaris holds a full German banking licence, which gives it the regulatory standing to offer deposit-taking products directly rather than relying on a separate bank partner. That distinction matters in a sector where several BaaS competitors operate as technology layers over a licensed bank, creating additional counterparty risk and compliance complexity. The German deposit guarantee scheme (Einlagensicherungsfonds) applies to deposits held at Solaris, which will be relevant to any ADAC cardholder weighing the savings product against alternatives. The competitive backdrop for BaaS-embedded savings is also developing quickly. Across Europe, several embedded-finance platforms and challenger banks have introduced savings products as a means of widening net interest margin, particularly at a time when central bank rate cycles have made deposit economics more attractive than they were for most of the low-rate decade. The promotional rate of 3.5% positions the ADAC product above the standard variable rate but below the leading easy-access rates available on the open market from specialist savings platforms, meaning ADAC cardholders who are already inside the app ecosystem are the primary target rather than active rate-shoppers. The next milestone to watch is whether Solaris and ADAC Finanzdienste extend the product set further, potentially into investment or lending products, as the embedded suite deepens.

How to read an AI Automation pitch before you trust it.

How to read an AI Automation pitch before you trust it. 2026-09-03 By Dumitru Condrea | Ex-General Manager for Solaris Bank, Regulatory Architect AI Automation Every week another short video promises the same thing: one open source tool, one weekend setup, and your entire content or ops workflow runs on autopilot. Some of these claims are grounded. Most are stretched further than the tool actually goes. Knowing the difference matters more for a regulated business than a personal brand, because the cost of trusting a broken automation is not a wasted afternoon, it is a compliance gap or a customer facing failure. Novafin recently reviewed a TikTok clip pitching exactly this kind of tool: an open source social media manager that schedules and crossposts across LinkedIn, YouTube, TikTok, and Instagram from one dashboard, with AI generating the content itself. Here is how Novafin broke the claim down, and what the same checklist looks like when you apply it to an automation pitch for a fintech operation. Step one: verify the tool actually exists and is what it claims. The video did not name the tool on screen, a common pattern in lead gen content where the value is gated behind a "comment to receive" funnel. A quick search against the described feature set (self hosted, open source, schedules and crossposts to the named platforms, AI generation features) matched a real, actively maintained project with thousands of stars and daily commits. That is a good sign. A tool with no discoverable match for its claimed feature set, or one that only exists as a landing page with no code behind it, is where most of these pitches fall apart. Step two: separate what the tool does from what the pitch implies. This is where the gap usually opens up. The video called the setup "easy." The actual stack is a full application requiring Docker, a database, and platform business accounts before it even connects to Instagram or TikTok. For a technical team, that is a normal afternoon. For the audience the video is speaking to, it is a meaningfully harder lift than promised. Neither claim is false on its own. The tool works as described, and the setup is real work. The pitch just compresses the second part almost to zero. Novafin see the same pattern in fintech automation pitches constantly. A vendor demo showing an AI agent approving KYC checks in seconds is showing you the model working on clean, pre sorted data. It is not showing you the exception queue, the audit trail requirement, or the six weeks of integration work connecting it to your actual case management system. The demo is not lying. It is just not showing you the part that determines whether the project succeeds. Step three: notice what evidence is missing. The video described what the tool could do. It did not show a working pipeline actually running: no screen recording of a real crosspost going out, no dashboard with live scheduled content. That distinction, described capability versus demonstrated result, is the single most useful filter when evaluating any automation claim, ours included. If a vendor or a creator cannot show you the thing actually running end to end, ask why. Step four: notice the incentive behind the pitch. The creator was not simply informing. The full guide was gated behind a comment, a standard audience building mechanic. That does not make the underlying tool bad, but it means the video's job was to generate engagement and leads, not to give you an unbiased setup guide. Every automation recommendation you receive, from a TikTok clip to a vendor sales call to an advisory firm's audit, carries an incentive. Knowing what that incentive is tells you how much scrutiny the claim needs before you act on it. Applying this to your own automation decisions. None of this means avoid automation. It means run every pitch, including the ones that sound most exciting, through the same four checks: does the tool actually exist and do what is claimed, what does the pitch leave out about implementation effort, is there demonstrated proof or just described capability, and what is the source's incentive for telling you this. This is the same process Novafin run when Novafin scope an AI audit for a regulated business: rank the processes that are genuinely automatable against the ones where the demo looks good but the operational reality (audit trails, exception handling, regulatory review) makes the real timeline much longer than the pitch suggests. Honest timelines beat exciting demos every time you are the one accountable for what breaks. If you want a second opinion on an automation claim your team is evaluating, or a straight assessment of where AI genuinely saves time in your operation versus where it just moves the risk somewhere less visible, that is exactly what its free AI audit is for. Evaluate your payment operations or compliance architecture. Novafin work with licensed EMIs, PIs, MSBs, and PSPs to map operational risk, automate compliance queues, and resolve regulatory bottlenecks.

German fintech Solaris pivots to AI-native banking, cuts 20% of staff to ride "huge wave" over financial services

Solaris, a German Banking-as-a-Service provider, is becoming "Europe's first AI-native bank" under CEO Steffen Jentsch, who joined in early 2026. The Berlin-based fintech, valued at $1.6 billion in 2021, is rebuilding its banking processes using AI agents and large language models whilst maintaining human oversight. The strategic pivot, backed by majority shareholder SBI Holdings, involved cutting 20 per cent of its 400-strong workforce. Solaris is focusing on Germany after closing subsidiaries in Italy, Spain and France. Its two major clients, ADAC and Boerse Stuttgart Group, comprise around 80 per cent of revenues. The company has pushed back its profitability timeline to 2028, following earlier restructuring in 2024 amid client losses and regulatory restrictions from BaFin.

German fintech Solaris cuts 20% of workforce in pivot to AI-native banking

German fintech Solaris is cutting 20 per cent of its 400-strong workforce, eliminating around 80 roles as it repositions itself as an "AI-native bank". The Banking-as-a-Service provider aims to increase automation across its processes and products, with AI agents handling operational tasks whilst humans oversee control and governance. The restructuring follows previous job cuts, a write-down and a rescue funding round by Japan's SBI Group. New CEO Steffen Jentsch is shifting Solaris from an embedded finance platform towards developing data and AI-driven financial services for partners including ADAC and Boerse Stuttgart Group. The company has secured investor backing for its repositioning strategy, with Jentsch describing the move as the "next logical step" following Solaris's pioneering work in cloud-based banking via APIs.

Solaris announces strategic transformation to become Europe's first AI-native bank.

Solaris announces strategic transformation to become Europe's first AI-native bank. Solaris management sets a new strategic direction to build a highly automated banking platform, backed by majority shareholder SBI. Berlin, March 25, 2026. Solaris has announced a comprehensive strategic repositioning and is starting its transformation into Europe's first AI-native bank. Just under three months after taking office, the new management team led by CEO Steffen Jentsch is setting a new direction: together with majority shareholder SBI Group (Tokyo), Solaris will develop its embedded finance platform into a pan-European financial infrastructure, with processes largely automated with artificial intelligence. The strategy builds on Solaris' German full banking license, its API-based platform, ten years of experience in the Banking-as-a-Service market, and long-term financial support guaranteed by SBI. Ten years ago, Solaris was one of the first companies in Europe to prove that cloud-based banking via APIs works. Today, Solaris is taking the next logical step. Solaris is developing a platform that combines this infrastructure with AI and rebuilds banking processes from the ground up. With the EU AI Act and DORA, Europe is creating the regulatory framework needed for this step. Together with SBI and in close dialogue with the regulatory authorities, Solaris is developing Solaris into an AI-native bank and creating new growth through the broad use of artificial intelligence in banking. Steffen Jentsch, CEO Solaris SE.
