Zurich, Switzerland · StartupClimeworks is a Swiss climate tech pioneer specializing in direct air capture (DAC) of CO₂ – essentially technology to filter carbon dioxide directly out of the atmosphere. Founded in 2009 as a spin-off from ETH Zürich by engineers Jan Wurzbacher and Christoph Gebald, Climeworks has the distinction of building the world’s first commercial DAC plants. Its modular CO₂ collectors use a special filter that binds CO₂ when air passes through, then releases pure CO₂ when heated, allowing it to be captured and stored or reused. In 2017 Climeworks opened a prototype DAC plant in Iceland in partnership with Carbfix, where captured CO₂ is injected underground and mineralized into rock. By 2021, they launched “Orca” in Iceland – the largest DAC plant at the time – able to remove 4,000 tons of CO₂ per year, selling carbon removal as a service to corporate clients like Stripe, Microsoft and Shopify. Climeworks gained widespread attention as the first DAC unicorn: in April 2022 it raised $650M in an equity round (Europe’s largest-ever climate tech funding) at a valuation reportedly around $2 billion. Investors include Carbon Removal Partners and Big Oil venture arms, reflecting broad interest in negative emissions tech. As of 2025, Climeworks is scaling up “Mammoth,” a 36,000 tCO₂/yr plant in Iceland, and planning multi-megaton facilities by 2030. The EU and US policy push for carbon removal (with 45Q tax credits, etc.) strongly benefits Climeworks. The company also sells captured CO₂ for reuse in drinks and agriculture (a smaller market) and operates demonstration units in countries like Switzerland and Italy. With global climate goals increasingly reliant on carbon removal, Climeworks is positioned as a leader in an emerging industry. It touts a goal of removing 1% of global CO₂ emissions by 2050. While challenges remain (DAC is energy-intensive and currently expensive, around $600/ton), Climeworks has achieved real progress – turning sci-fi into reality. Its name comes up frequently in climate policy discussions, and it was highlighted at COP26 as an example of scalable climate innovation. In summary, Climeworks is a trailblazer in direct air capture, turning a bold lab idea into the world’s first commercial carbon removal service, putting Zurich on the climate tech map.

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.
