## Questions

### Who runs investment decisions at Sirius Venture Partners?

Managing Partner Friedrich von Diest has the final say on commitments. He has been an active business angel and founder since 1992 and personally sourced, financed and exited roughly 25 technology companies before formalizing the Sirius platform in 1998. Co-Managing Partner Michael Blum oversees organizational development and communications but the investment pipeline flows through von Diest and the Venture Partners he selects.

### How does Sirius Venture Partners source proprietary deal flow?

Sourcing depends on von Diest's 30-year network of entrepreneurs, operators and fellow business angels concentrated in the German Mittelstand technology ecosystem. The firm's Venture Partners — former interim managers, corporate-strategy advisors and eco-tech specialists — bring their own regional and sector-specific relationships. Sirius explicitly markets this as a 'hochkarätiges Netzwerk' and lists more than 2,500 evaluated business cases as evidence of top-of-funnel reach.

### What investment stages does Sirius typically target?

The firm invests from late seed ('späte Seed-Phase') through expansion and into founder-succession situations. Von Diest's track record includes company formation, growth financings, M&A-led consolidation and IPOs with volumes up to EUR 100 million, so the team is comfortable holding positions across the full corporate lifecycle — provided the company exhibits what the firm calls 'überdurchschnittliches Wachstumspotenzial'.

### Which sectors does Sirius explicitly avoid?

Sirius does not publish a formal exclusion list. The stated focus is innovative technologies, products and business models with above-average growth potential. Its Venture Partners' functional expertise covers enterprise software, industrial tech, digital health and climate-related enterprises; sectors outside those domains are unlikely to meet the partnership's underwriting criteria.
