Background

Auxxo is a Berlin-based seed-stage venture capital firm founded in 2021 with an explicit mandate to back female-founded companies at pre-seed and seed. The fund was established by Constanze Buchheim and Catharina van Delden, two German entrepreneurs with backgrounds in HR-tech and innovation consulting, with the thesis that female-founded startups are systematically underserved by mainstream European VC. Auxxo typically writes initial cheques of €250,000 to €1m and focuses on B2B software, health, and deep tech.

The fund is a participant investor rather than a lead, often co-investing alongside larger European seed funds. Its presence in cross-border syndicates signals both the EU-facing Nature of the UK deep-tech ecosystem and a broadening of the capital sources that back British science-led companies. Auxxo participated in BioOrbit's £9.8m in-space drug manufacturing seed round in April 2026, alongside LocalGlobe, Breega, Seedcamp, Type One and 7percent.

Auxxo's involvement in BioOrbit is representative of a pattern in the 2026 UK funding window: international specialist funds entering British rounds as part of multi-investor syndicates rather than leading standalone national rounds. For BioOrbit's founding team, which includes female co-founders, Auxxo's participation is consistent with the fund's stated thesis.
