The filter compares a healthy acquisition strategy to adding compatible branches to a strong tree trunk. The acquirer first needs a clearly defined core: culture, client promise, operating model, and professional philosophy. It then evaluates each target's leadership because the leader's behavior often predicts the culture throughout the firm. A candidate advances only if its people demonstrate collaborative, consultative, and service-oriented behavior and genuinely want to adopt the acquirer's broader model. The target must also accept non-negotiable professional standards, such as planning-led advice and the established investment philosophy. Finally, the acquirer identifies exactly where the new branch belongs. This selectivity sacrifices deal volume but supports employee retention, client conversion, integration, and faster post-acquisition growth.
Origin
Creative Planning formed this filter after an initially accidental Minneapolis acquisition retained its team, expanded client services, and accelerated growth, revealing a repeatable expansion model.
Core principles
- 01Build a coherent operating core before accelerating acquisitions
- 02Leadership character predicts the acquired firm's culture
- 03Acquire for strategic fit rather than deal volume
- 04Require alignment on service model and investment philosophy
- 05Mutual enthusiasm improves retention and post-deal growth
How to run it
- 1
Build the Trunk
Establish a coherent culture, client proposition, operating model, and professional philosophy before pursuing acquisition scale. Make the non-negotiable elements explicit.
Pro tip Document which practices may vary locally and which must remain consistent everywhere.
Watch out Acquiring aggressively before the core is stable can create a collection of firms rather than one enterprise.
- 2
Screen the Leader
Meet the target's leader early and assess attitude, communication, kindness, collaboration, and servant leadership. Treat this person as a strong indicator of the wider organization.
Pro tip End the process early when the interpersonal connection or values alignment is clearly absent.
Watch out A financially attractive firm led by an incompatible person can import conflict throughout the organization.
- 3
Test Service Alignment
Confirm that the target wants to deliver the acquirer's complete client model rather than merely access its capital or brand. Require willingness to address adjacent client needs where relevant.
Pro tip Use realistic client scenarios to test whether the target embraces the broader model.
Watch out Verbal enthusiasm without operational commitment will surface as resistance during integration.
- 4
Test Philosophical Alignment
Verify that the target will adopt the core professional and investment principles. Eliminate candidates whose fundamental approach conflicts with the enterprise.
Pro tip Discuss actual portfolios, planning practices, and client recommendations rather than relying on broad labels.
Watch out Different underlying philosophies can make consistent client service impossible.
- 5
Place the Branch
Define how the firm fits geographically, operationally, and culturally before closing. Ensure both sides understand the target's future role and genuinely want the combination.
Pro tip Specify the additional services, referrals, and capabilities that should improve the acquired firm's growth.
Watch out A deal without a clear integration destination risks becoming another disconnected office.
In the wild
Creative Planning acquired a father-and-son firm in Minneapolis. Its advisers stayed, clients received more services and made more referrals, and the firm's growth rate increased while Creative Planning doubled its presence in the city.
→ The experience became the recipe for expanding through carefully aligned acquisitions.
An acquirer finds a profitable advisory firm, but its leader dismisses collaborative planning and refuses to adopt the buyer's investment philosophy. The buyer ends discussions after the initial meeting rather than trying to repair the mismatch after closing.
→ The acquirer preserves organizational coherence and avoids a costly integration conflict.
Common mistakes
Buying Before Building
A company without a strong operating core cannot clearly determine where acquired businesses belong.
Prioritizing Deal Volume
Doing deals merely to become larger admits firms that do not support the intended client experience.
Ignoring Leadership Character
Financial and operational diligence cannot compensate for a leader whose behavior conflicts with the buyer's culture.
Is it for you?
Best for
It is best for established companies using acquisitions to expand geography, capabilities, or market presence.
Not ideal for
It is not ideal for financial buyers pursuing loosely integrated roll-ups or short-term deal volume.
From the transcript
“This is the recipe, And we went back and started to call all the advisors over the years that had called us, and the acquisitions…”
“the leader of the firm usually is indicative of the whole firm”
“We spent fifteen years building something from scratch, right, so we built a very strong tree trunk.”
