Today, more than 100,000 teams around the world use the firm’s platform. This rapid adoption is a testament to its power and trust in advancing cybersecurity best practices.
According to the Aikido team, “in an industry dominated by Palo Alto and Tel Aviv heavyweights, Aikido shows that Europe can build a world-class software security company and win globally.” This forward-thinking spirit serves Aikido’s entrepreneurial drive for innovation and excellence, making it a crucial player in the global international market.
Osapiens and Preply Join the Ranks
Osapiens, which got started in Mannheim in 2018, has recently gained a lot of attention. In December 2021, they closed a $100 million Series C funding round, led by Decarbonization Partners.

In the same spirit, language-learning marketplace Preply became the latest edtech unicorn when it hit a $1.2 billion valuation.

Preply’s recent success underscores just how quickly the demand for language education platforms is taking off. Today, more people want to learn new languages than ever before, in our increasingly globalized world.
Cast AI’s Continued Growth
Then in April 2025, Cast AI went all-in, raising a massive $108 million in its Series C funding round. That flood of investment has launched its valuation over the $1 billion threshold.
