Frequently asked questions

Who runs investment decisions at SquareOne?

Partners Georg Stockinger and Christian Buchenau lead SquareOne's investment committee. Stockinger joined in 2016 after a career spanning McKinsey, Rocket Internet, and Fab.com, while Buchenau had been investing since 2010 through the firm's predecessor, Paua Ventures.

How does SquareOne source proprietary deal flow?

SquareOne's first-customers guarantee requires the team to maintain active relationships with corporate buyers across industrial, logistics, and manufacturing sectors. Those relationships double as early signal networks, giving the firm access to founders building solutions for specific enterprise pain points before they reach broad market auction.

Is SquareOne structured as a single family office or does it operate more like a venture firm?

SquareOne operates as a venture capital firm. AUM is undisclosed, but the firm raises external capital and deploys it across a concentrated portfolio of B2B software and deep tech startups, making direct equity investments at pre-seed and seed stage.

What investment stages does SquareOne typically target?

SquareOne focuses on pre-seed and seed-stage companies. The firm writes first checks into B2B software and deep tech startups, often before a product has achieved significant commercial traction, and supports founders through early go-to-market execution.

Which sectors does SquareOne avoid?

The firm publishes no explicit avoidance list, but its portfolio and stated mandate concentrate heavily on B2B software, deep tech, AI/ML, robotics, cybersecurity, climate tech, and quantum computing. Consumer internet, direct-to-consumer brands, and pure-play marketplaces appear absent from its current portfolio.

Does SquareOne participate in fund commitments or only direct deals?

SquareOne invests directly in portfolio companies. There is no public evidence of the firm acting as a limited partner in other venture funds; its model centers on active early-stage equity positions with hands-on operational support.

Does SquareOne maintain philanthropic structures, and how are they separated?

No philanthropic foundation or impact-investing vehicle is disclosed on SquareOne's website or in available public materials. The firm operates a single commercial venture capital vehicle focused on financial returns.
