Real Talk Takeaways
1. Specialization isn't just a marketing tactic. It's about building deep, internal expertise in a specific area.
2. Generalist agencies can succeed, but often only after reaching a significant scale that smaller shops can't match.
3. Clients pay a premium for confidence; a specialized agency inspires more trust than a generalist.
4. You can still take on work outside your specialization, but your external messaging must remain focused to attract your ideal clients.
5. To identify your natural path to specialization, identify the types of clients you've served repeatedly. Look at them as "clusters" in your existing client base.
6. For acquirers, a specialized agency signals higher retention, longevity, and profitability, which directly translates to a higher valuation.
7. The path to specialization is a journey, not a flip you switch. Start by leaning into what you're already good at.
