M&A : ADVISORY : IPO








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.
No upfront fees, no retainers, no hourly rates
