The history of SAP
Five engineers left IBM in 1972 with one idea: standard software to run a whole company in real time. Today that software moves a vast share of global commerce.

When you buy something at a large chain, when a factory sets a price or when a bank closes its books, there is a good chance SAP software is running quietly behind it. The German company, founded by five former IBM employees in 1972, is invisible to consumers yet omnipresent in the guts of the world economy. This is the story of how five engineers defined an entire category of software.
Five engineers and a rejected idea
On 1 April 1972, Dietmar Hopp, Hasso Plattner, Claus Wellenreuther, Klaus Tschira and Hans-Werner Hector left IBM and founded SAP, short for Systemanalyse Programmentwicklung, System Analysis and Program Development. Their idea was radical for the time: instead of programming custom software for each company, create standard software that integrated every business process and handled data in real time.
They worked at the data centre of their first customer, the German subsidiary of the chemical firm ICI. Over time, the headquarters settled in Walldorf, a small German town that became the heart of the world's enterprise software.
From R/1 to R/3, the product that changed everything
The evolution of the product tells the story of the sector. First came SAP R/1, a financial accounting system. In 1979 came R/2, a mainframe suite that thrived among European multinationals in the 1980s.
But the real turning point was R/3, launched in July 1992. The R stood for real time, and the 3 for its three-tier client-server architecture. R/3 freed companies from mainframes and let SAP expand across the world. It was the product that turned a German company into the undisputed global leader.
Inventing the ERP category
SAP did not just sell a product: it defined an entire category, that of the ERP, Enterprise Resource Planning. An ERP is a company's nervous system, the software that connects finance, inventory, sales, human resources and logistics into a single source of truth.
- A single system integrates every area, avoiding disconnected islands of information.
- Data is processed in real time, not in overnight batches as before.
- SAP serves around 440,000 customers in more than 180 countries.
- A huge share of the world's business transactions passes, at some point, through an SAP system.
In 1988, SAP went public in Germany, and in 1998 it listed in New York as well. But its real recent reinvention came with the in-memory database HANA, unveiled around 2010 and 2011, and with S/4HANA in 2015, its next-generation ERP. Today the company pushes its customers toward the cloud with the RISE with SAP offering.
SAP today
In fiscal 2025, SAP reported revenue of 36.8 billion euros, of which 21.02 billion came from the cloud, now its largest revenue stream. Its cloud backlog reached a record 77 billion euros. In March 2025, SAP briefly became the most valuable listed company in Europe, a milestone that reflects the scale of its transformation toward the cloud.
Q4 was a strong cloud quarter, with bookings resulting in 30% Total Cloud Backlog growth to a record 77 billion Euros. — Christian Klein, CEO of SAP, on the 2025 results.
What SAP teaches us
SAP's great bet was standard software over the bespoke kind. Instead of reinventing the wheel for each client, they created a platform many companies could adopt and adapt. That same logic underpins modern management software: any business that automates its calendar, its CRM or its customer service with well-designed standard tools gains efficiency without building everything from scratch. Integrating data into a single source of truth remains, half a century later, the greatest competitive advantage of enterprise software.
