Munich, Germany · StartupCelonis is a Munich and New York-based enterprise software company that pioneered the field of process mining – technology that analyzes a company’s IT event logs to visualize and optimize its business processes. Founded in 2011 by three friends (Alexander Rinke, Bastian Nominacher, and Martin Klenk) out of university in Munich, Celonis bootstrapped in its early years and landed Siemens as a key pilot customer for its process analytics tool. The software proved invaluable in identifying inefficiencies in processes like order-to-cash, procurement, and inventory management. By 2015 Celonis was the leader in this niche, and it partnered with SAP which resold Celonis as SAP Process Mining by Celonis. Venture capital soon followed: Celonis raised $27.5M in 2016 (Series A) then $50M in 2018 (Series B). Its growth was massive – from €1M ARR in 2012 to well over €100M by late 2010s. In 2019, Celonis raised $290M at a $2.5B valuation, making it a unicorn. It wasn’t done: by June 2021, Celonis announced a $1B Series D round valuing it at $11 billion, one of Europe’s largest software funding rounds. And in 2022, Celonis reportedly reached a $13B+ valuation, firmly cementing it among Europe’s most valuable private tech companies. The company’s product evolved into the Celonis Execution Management System (EMS), which not only discovers processes but also suggests and implements improvements (sometimes via RPA bots or triggering workflows). Celonis counts thousands of enterprise customers – including Siemens, BMW, Coca-Cola, Uber – and its software helps them save billions by cutting throughput times, reducing errors, and optimizing resource use. With dual HQs in Munich and New York, Celonis has aggressively expanded in the U.S., competing with companies like IBM’s process mining. The firm is also eyeing an IPO; CEO Rinke has mentioned that Celonis is positioning itself for a public listing when market conditions are right. In the meantime, Celonis keeps growing (estimated $400M+ ARR in 2023) and acquiring smaller tech startups to bolster its platform. Celonis epitomizes the success of enterprise software from Europe – deeply technical, essentially creating a new category, and achieving decacorn status within a decade.

Munich, Germany · StartupPersonio is a Munich-based HR software company that has become one of Europe’s most valuable SaaS startups. Founded in 2015 by Hanno Renner (CEO) and three co-founders from the Technical University of Munich, Personio set out to streamline HR management for small and mid-sized businesses. Its cloud platform offers an “all-in-one” suite – from recruiting and applicant tracking to payroll, attendance, and performance management. Personio’s focus on Europe’s underserved SME segment paid off spectacularly: as of 2024, the company serves 12,000+ customers across 70 countries (primarily firms with 10–2,000 employees). This rapid growth attracted major VC funding. Personio became a unicorn in January 2021 with a $1.7 billion valuation, and by October 2022 it raised a $200 million Series E extension at a staggering $8.5 billion valuation – making it one of Europe’s most valuable private tech companies at the time. Investors like Index Ventures, Accel, Lightspeed, and Greenoaks have backed Personio. The company has since expanded to 8 offices (including London, Dublin and Amsterdam) and grown to about 2,000 employees. Despite the size, Personio continues to post strong metrics: in 2023, revenue reportedly doubled and the firm reached over 15,000 customers by 2025. Personio’s success is often attributed to its user-friendly, modular platform tailored to non-technical HR teams at smaller companies. It integrates with 100+ other business tools and emphasizes automation of routine HR tasks. Now valued at $8.5 billion+, Personio is widely seen as a future IPO candidate and a role model for Europe’s B2B SaaS boom – proving that an “SMB HR” niche can scale to a global category leader.
