Three Keys Lab

Three Keys Lab focuses on early-stage enterprise software, industrial technology, and digital infrastructure companies. The firm targets pre-seed and seed rounds across Finland, Estonia, Sweden, and the broader Baltic region. It avoids consumer-facing startups, life sciences, and capital-intensive hardware, concentrating instead on B2B SaaS, cybersecurity, and developer tools where the founding teams have deep technical expertise.

Investment decisions are made directly by the firm's general partners, without an external investment committee. Three Keys Lab operates with a lean team structure typical of Nordic micro-VCs, where the partners are former technical operators who conduct their own engineering and product diligence. Specific partner names are not publicly emphasized — the firm's low profile reflects a deliberate choice to keep the focus on portfolio founders rather than on the investors themselves.

Three Keys Lab is a genuinely small, independent micro-fund in a landscape where most Nordic VC peers have scaled into multi-fund platforms or been acquired by larger European asset managers. The firm writes smaller first checks than platforms like Northzone or EQT Ventures, carries fewer than fifteen active positions, and does not operate a venture builder or studio model. Its limited partners are predominantly Finnish family offices and high-net-worth individuals, which eliminates the deployment velocity pressure that comes with institutional capital.

Three Keys Lab typically writes early checks ranging from €200,000 to €800,000 and is comfortable both leading small pre-seed rounds and participating as a co-investor in seed rounds led by larger Nordic or European funds. The firm does not lead large Series A financings but may exercise pro-rata follow-on rights in portfolio companies that reach that stage.

Three Keys Lab's primary investment geography is the Nordics and Baltics, with a heavy concentration in Helsinki, Tallinn, and Stockholm. The firm also reviews opportunities in Copenhagen and Oslo, though deal flow from those cities is less frequent. Three Keys Lab does not invest in North America, Asia, or Southern Europe, maintaining a deliberately tight regional focus.
