Start with the reason this business could matter.
A buyer thesis is not a list of companies that sound large or wealthy. It states what the buyer could gain: a customer relationship, category capability, distribution route, product adjacency, operating platform or focused asset they can run. The reason must be grounded in the actual business, not in generic optimism.
Define the buyer types before the names.
Consider operator buyers, strategic buyers, specialist teams or holding companies only where their operating context creates a plausible fit. For each type, ask what they would need to understand, what they might worry about and what a handover would require. This produces better research questions than a broad contact list.
Use public and professional signals proportionately.
Research can draw on public business information, product direction, market focus and visible capabilities. It should never become indiscriminate mass outreach or a claim of access. The work is to prioritise relevance, decide where contact is appropriate and keep the owner’s context protected.
Let the thesis improve the brief.
The exercise often reveals what the seller needs to explain better: a transfer path, customer value, technical asset or operating dependency. That feedback makes the business more legible whether or not a specific buyer is ever contacted.
