With 25 years of M&A experience Wiese & Stone can design with you a bespoke solution with the best possible outcome


Our Story

Wiese & Stone is a mid-market M&A advisory that facilitates strategic business mergers and acquisitions

In essence, we’re the intermediary between the entrepreneur and the buyer, and we work with both to negotiate results-focused purchases that deliver the best of outcome for all.

With the larger ($50m+) M&A sector already well served by investment banks and corporate advisory firms, and the smaller end (under $5m) supported by small business brokers, commercial real estate agents and

 accounting firms, we were established to serve mid-market transactions of $5m to $50m.

We offer a highly personalised, bespoke solution to most industries (excluding mining, energy, aviation, infrastructure, and utilities). Visit Industries covered for more information.
