- Upwood
Led · Seed · Dec 2025
Upwood operates a sustainable investment marketplace that links forest owners with both individual and institutional investors, lowering the entry barrier to forestry assets. The platform leverages geospatial verification and blockchain infrastructure to deliver transparent, regulated, and ESG-aligned investment products. Current offerings include equity and debt instruments, with tokenized green securities planned for future release. By broadening access to impact-driven forestry investments, the company supports responsible forest management while opening a new real-asset class to global capital markets.

The fresh capital is earmarked for product development, navigating regulatory approvals, and accelerating go-to-market efforts across the EU.
- Every Health
Participated · Seed · Oct 2025
Every Health is a German digital-health startup building the first virtual clinic in Europe devoted to LGBTQ+ and broader sexual-health services. Its platform offers end-to-end care pathways that include at-home testing, online consultations, e-prescriptions and discreet medication delivery, all supported by a network of partner doctors, pharmacies and laboratories. In its first year of operation the company has already served thousands of users across Germany, validating demand for culturally competent, judgment-free healthcare. While initially focused on LGBTQ+-specific needs such as PrEP access and gender-affirming care, the service is also positioning itself as a mainstream sexual-health provider to anyone facing stigma or geographic barriers in traditional systems. Management points to a €150 billion annual LGBTQ+ healthcare spend in Europe and data showing 46 % of queer patients hide their identity from clinicians, underscoring the market gap. Proceeds from the latest financing will fund new remote diagnostics and treatment pathways and underpin expansion to additional European countries. The company has not disclosed revenue figures but emphasizes rapid user growth and partnerships as early traction indicators.
