Glaux

The firm leans heavily on the technical networks of its two founders, which extend through ETH Zurich, Carnegie Mellon University, and the broader Duolingo alumni community. Glaux prioritizes opportunities where its principals can diligence the underlying technology firsthand—an advantage rooted in their engineering backgrounds. They also co-invest alongside venture funds and participate in syndicates that surface through the Swiss and German startup ecosystems.

Glaux concentrates on enterprise software, applied artificial intelligence, fintech infrastructure, climate technology, and digital health. Across these sectors, the firm pursues a mix of early-stage venture, growth equity, and selective public-market technology positions. The investment approach is concentrated, with the partners writing meaningful checks into a curated set of companies rather than spraying small bets across a broad portfolio.

Duolingo is the wealth-origin entity for Glaux's capital base. Severin Hacker remains a director and significant shareholder of Duolingo, while Daniel Glauser holds shares from his tenure as an early employee. Glaux operates independently of Duolingo and makes no investment decisions on behalf of the company, though the founders' continued visibility into consumer-technology product cycles informs their investment lens.

No. Glaux does not publicly report assets under management, total deployment, or portfolio valuations. The firm's private-capital structure means it is not required to file public disclosures with Swiss or US securities regulators, and the principals have chosen to keep these figures confidential.
