Obsidian — M&A Advisory
The Partners

A note from
the founders

Founded in 2025, Obsidian set out to build what the European market was missing: an M&A advisory designed for small- to medium-sized businesses worth between €1M and €200M.

For decades, traditional investment banking overlooked smaller transactions. Large teams and slow processes made these transactions uneconomical. Owners were left with unspecialized brokers and outdated workflows. That’s where we step in.

We didn’t just want to make M&A more efficient by building a marketplace or a listing portal. We wanted to provide end-to-end M&A services that combine strategy, technology, and special care for a smooth, unproblematic company sale. Because selling your life’s work is emotional and shouldn’t be treated like any other transaction.

We make it our mission to help smaller businesses find the right successor and provide the optimal future for their employees. Because every transaction changes our lives as much as it does theirs.
