Maki.vc (Web3)

Check: Maki targets first rounds below EUR 5 million and supports consequent rounds; this is a firm round criterion, not Pirkka's personal check range. Active new investments come from Fund III.

Pirkka backs ambitious Nordic teams at their first rounds, combining an operator's technology and scaling perspective with Maki's sector-agnostic, non-consensus approach. His attributed investments favor experienced teams rebuilding large industries with scalable platforms—payments, sustainable construction materials, physical-world digital twins, enterprise systems, and other deep or brand-driven technologies.

Maki.vc (Web3)

Check: Maki's published sweet spot is first rounds below EUR 5 million from day zero; this is a firm round-size criterion, not Paavo's personal check range. Fund III is the active new-investment vehicle, with selective follow-ons from older funds.

Paavo backs Nordic deep-tech founders at their first institutional round when a radical scientific or engineering advance can overhaul an industry. He requires a credible technical foundation, balanced technical and commercial talent, control of a valuable position in the value chain, deep customer understanding, and a distinctive brand capable of making complex technology category-defining.

Union Square Ventures (USV)

Check: USV states that the firm writes $1 million to $30 million checks and invests from the earliest stages through the full company journey. This is a firm-wide range, not Albert's personal check authority; decisions are discussed collectively without a formal vote.

Albert is a thesis-driven generalist investing at the edge of large markets under technological and societal pressure. His current work emphasizes AI-enabled scientific discovery, robotics that can operate reliably in complex physical environments, resilient energy and civil infrastructure, and products that expand human agency. Across these areas he looks for compounding data or participation loops and systems that turn rapidly improving technical capabilities into durable real-world utility.
