Paavo Räisänen came to venture investing after working as an operator, including a move from business strategy into product management, and he invests across a wide mix of areas like B2B software, fintech, and deep tech fields such as industrial climate tech, alternative proteins, nanotechnology, and quantum computing, often favoring startups that rework an entire value chain rather than just improving one step. He stays closely involved with the founders he backs, paying close attention to how well a company understands its customers and how well its product, sales, and tech teams work together, and he has also spoken early about areas like stablecoins, European crypto rules, and the potential of quantum computing to open up new opportunities in software.
