## Questions

### Who runs investment decisions at Surplus Invest?

CEO and Founder S.A. Lüdke leads investment decisions, supported by a partnership group that includes M. Büschl (COO and Head of Corporate Growth), C. Stransky-Greifensfels, Dr. F. Closset, and A. Caretti. The firm has not disclosed a separate investment committee. Mr. Lüdke's background includes Partners Group and BCG's Principal Investors & Private Equity practice.

### How does Surplus Invest source proprietary deal flow?

ALP.X sources opportunities through three integrated verticals — real estate, infrastructure, and corporate growth — each of which offers advisory, development, and asset management services. These service mandates create visibility into off-market projects. The firm's partners also co-founded OMUNITI, a German real estate project developer, providing a direct pipeline of development-stage deals in the Berlin and Frankfurt regions.

### What investment stages does Surplus Invest typically target?

The Altss research record originally flagged early-stage and growth venture, but the firm's own public materials describe a real-asset developer and advisor with no stated venture-stage framework. Portfolio evidence points to development and repositioning projects — such as condominiumization of a monument-protected Munich residential block and mixed-use neighborhood ground-up developments — rather than startup equity rounds.
