The scent of coffee and the quiet bustle of a Monday morning permeate the executive floors of SAP SE in Walldorf. But the calm is deceptive. Europe's most valuable software corporation is facing a fundamental realignment. A radical thesis from Silicon Valley, suggesting that Artificial Intelligence (AI) could render traditional software obsolete, is shaking the foundations of a business model that was considered untouchable for decades: Software as a Service (SaaS).
At a glance: The rapid development of AI is challenging the traditional business model of software giants like SAP. Instead of complex, static applications, dynamic AI agents could take over the work. SAP is meeting this threat with a radical corporate restructuring, focusing on the integration of AI into its existing, data-rich enterprise systems. In doing so, the company is positioning itself as a central raw material supplier in the AI economy, though it still has to convince customers who are often still struggling with cloud migration.
The Death of Software? A Thesis Shaking SAP's Foundation
The idea circulating in tech circles as "Fast Fashion Software" is both captivatingly simple and disruptive: AI agents could generate software in seconds and discard it just as quickly, tailored to specific needs. This would fundamentally change the economic logic of the software industry, shifting away from fixed development costs and mass distribution toward a demand-driven approach with ongoing inference costs and individual customizations.
The fear of the obsolescence of classic software is palpable. SAP's stock experienced significant declines in early 2026. Following the release of its Q4 and full-year 2025 results on January 29, 2026, the share price fell by 15 percent—the sharpest daily loss since October 2020—wiping out over 40 billion euros in market capitalization. By February 20, 2026, the share price had dropped by about a third compared to the previous year. Christian Klein, CEO of SAP, admitted in an interview in late February 2026 that the stock had fallen 40 percent from its peak, though he emphasized the resilience of the strategy. Analysts like Angelo Meda of Banor SIM consider the concern regarding the value of SAP's services justified, as AI could make many modules easier to develop and replicate, thereby lowering the average selling price of services.
Data Instead of Models? SAP's Counter-Thesis and the European Opportunity
However, a different conviction prevails in Walldorf. The AI competition, they are certain, will not be decided by the best models, but by the best data. And it is precisely this data that is most structured within SAP's systems. AI agents only become truly useful if they not only have a powerful model but can also access a company's context and internal systems to understand procurement processes, supply chains, or production workflows. Christian Klein emphasized as early as July 2025 that the benefits of AI only materialize when it is deeply embedded in business processes and rests on three pillars: modern cloud software, modern data management, and a consistent stack of AI technologies.
SAP has never tried to build the next large language model to compete directly with OpenAI or Anthropic. The strategy was different from the start: to embed existing models into its own products and create value where they meet real business processes. In February 2026, Klein reaffirmed a comprehensive five-point strategy that relies on artificial intelligence and a unified data architecture to integrate AI natively into core workflows and break down data silos. The counter-bet is this: models will become interchangeable over time. What will truly be decisive is no longer just which model is running in the background, but who holds the data that allows AI to function meaningfully in companies in the first place. For Europe, this could be the real opportunity: not in building the next ChatGPT, but in the corporate data that is generated anew every day in industry and the economy. According to a Bitkom study from March 2026, 41 percent of companies in Germany are already using AI, and another 48 percent are planning or discussing its implementation.
Marketing Over Reality? The Challenges of SAP's AI Strategy
The German software giant has long approached the topic of AI with caution. Since 2023, however, SAP has been trying to close the gap. Under the "Business AI" label, the company is building AI functions into its existing products. Shortly thereafter, it introduced "Joule," its own assistant, which is intended to become the entry point for these functions across the SAP world. Joule is integrated into almost all of SAP's cloud solutions and is designed to increase productivity by streamlining workflows and automating repetitive tasks. By the end of 2025, SAP had integrated over 350 AI functions, including Joule Agents, and more than 2,400 Joule Skills into its portfolio. With the Joule Analytics Center, customers receive detailed insights into user engagement and usage data.
In practice, however, the major breakthrough has yet to materialize. The DSAG Investment Report 2026, based on a survey of 198 SAP user companies conducted between late 2025 and January 2026, shows that while 43 percent of companies have implemented AI use cases productively, the majority are not relying on SAP solutions to do so. Jens Hungershausen, Chairman of the DSAG board, noted that investment decisions are driven less by visions and more by feasibility, cost-effectiveness, and integration capability. A Horváth study from November 2025 found that six out of ten companies currently undergoing an S/4HANA transformation do not feel agile enough to implement the AI copilot Joule in parallel. Many companies are still in the middle of the transition to S/4HANA and cloud migration. According to the valantic SAP Study 2025, while 40 percent of companies have ongoing S/4HANA migration projects and 27 percent have already completed them, the path is often rocky, as evidenced by the fact that 84 percent of companies experienced setbacks after an initial cloud migration. Furthermore, the use of AI functions is often tied to cloud solutions, excluding on-premise customers.
The Great Restructuring at SAP
SAP is responding to these challenges not only with new AI functions but with a comprehensive corporate restructuring. Christian Klein no longer views AI as an additional product module, but as the next major transformation for SAP. It was similar at the end of 2020, when Klein radically oriented the company toward the cloud, which paid off: for 2026, SAP expects cloud revenue of 25.8 to 26.2 billion euros.
Now, the same feat is to be accomplished again, this time with AI. Klein has committed the approximately 110,000 employees to a new corporate restructuring. The product portfolio, sales, licensing, and internal processes are to be reorganized. This is also reflected in the executive board: Christian Klein is relinquishing responsibility for sales to focus more heavily on artificial intelligence. Thomas Saueressig (40), who has been on the SAP board since 2019, will take over the newly created "Customer Value Group" as Chief Customer Officer starting April 1, 2026. This new unit bundles the entire customer journey—from sales to delivery, service, and support—to accelerate the adoption and use of SAP's cloud and AI-powered solutions. Klein emphasized that in a business where adoption and renewal define success, the boundaries between sales and delivery are disappearing.
Christian Klein and the European AI Bet
Christian Klein has already led SAP through one deep and painful restructuring: away from the classic licensing business toward the cloud. Now, Klein faces the next turning point, which is potentially even riskier. Because this time, it is not just about a new sales model, but about the question of what role software plays at all when AI takes over more and more tasks.
SAP never wanted to build the one large language model that competes directly with OpenAI or Anthropic. The bet was different from the start: that models would become interchangeable and that, in the end, it is not the model alone that decides, but the integration into real business processes and access to corporate data. This is exactly where the real European opportunity might lie: not in the next billion-dollar race for the largest model, but where AI can work with real data from industry, logistics, procurement, and production. SAP is currently more than just a company under pressure—SAP is a test case for Europe. If Europe's most important software company proves that structured business data is the true raw material of the AI economy and that AI is not the goal, but the new operating system for modern business processes, then the supposed laggard could end up being one of the most important winners after all.
Frequently Asked Questions
What is the "Fast Fashion Software" thesis in the context of AI and SAP?
The "Fast Fashion Software" thesis suggests that in the future, AI agents could be capable of generating specific software applications dynamically and in seconds, adapting to changing business requirements and disappearing just as quickly. This would render traditional, static software solutions like SAP obsolete and fundamentally change the economic logic of software development.
What role does data play for SAP in the AI era?
SAP is convinced that the real value of AI lies in the quality and structure of the data, not primarily in the AI models themselves. SAP's systems contain highly structured business data that is essential for AI agents to act meaningfully and understand business processes with the necessary context. Christian Klein emphasized that AI only brings benefits when it is deeply embedded in business processes and built on modern cloud solutions and data management.
How is SAP responding to the challenges of the AI revolution?
SAP is responding with a comprehensive corporate restructuring to position itself as a central player in the AI economy. This includes integrating AI functions like the assistant Joule into existing products and realigning the product portfolio, sales, and internal processes. Christian Klein has also relinquished responsibility for sales to focus more on artificial intelligence and appointed Thomas Saueressig as Chief Customer Officer, who will lead the new Customer Value Group to strengthen customer loyalty.
In Summary
