Distinguish between everyone who might purchase the product and the specific customer the company chooses to serve exceptionally well. The chosen customer should be a segment where the company can win against competitors by delivering a better product and buying experience. For horizontal or touchless products that naturally attract many users, cohort retention provides evidence: identify who stays, investigate why, and use that signal to focus the initial strategy. Once selected, the customer becomes a coordination mechanism for product priorities, marketing messages, sales motions, and experience design. This focus also creates differentiation because the company can make decisions competitors serving a broader market will not make. Choosing a customer creates risk by excluding some opportunities, but refusing to choose usually produces fragmented road maps, sub-optimized campaigns, and shallow value for every persona. The selection can evolve as the product becomes more sophisticated.

How to run it
- 1
Map Possible Buyers
List the customer types currently buying, trialing, or considering the product. Treat this as a market map rather than a commitment to serve everyone.
Pro tip Separate users, buyers, and economic decision-makers when they differ.
Watch out Revenue from a persona does not automatically make it the strategic priority.
- 2
Find Where You Can Win
Evaluate which group the company can serve more effectively than competitors. Look for strong problem intensity, product fit, and an opportunity to make differentiated choices.
Pro tip Ask what you would build or communicate differently if this were the only customer that mattered.
Watch out Market size alone does not establish an advantage.
- 3
Use Retention as Evidence
For a horizontal product, compare retention by customer cohort and investigate why the strongest cohort stays. Use the findings to refine the target.
Pro tip Combine behavioral data with interviews so you understand the mechanism behind retention.
Watch out Do not assume the largest acquisition cohort is also the best long-term segment.
- 4
Choose the Priority Customer
Name one primary persona or tightly bounded segment. State why the company is willing to optimize the product and buying experience for this group.
Pro tip Write a concise declaration that product, sales, and marketing teams can all use.
Watch out Six priority personas at an early stage usually means there is no priority.
- 5
Align the Organization
Adjust the product road map, positioning, channels, sales motion, and experience around the chosen customer. Resolve conflicting decisions in favor of the declared segment.
Pro tip Use the target customer as a filter in roadmap and campaign reviews.
Watch out A persona document has no value when teams continue making generic decisions.
- 6
Review Without Diluting
Revisit the decision as the product matures and evidence changes. Expand deliberately only when the company can serve another segment without weakening its core advantage.
Pro tip Require a clear strategic reason and dedicated resources before adding a new priority segment.
Watch out Do not broaden the target merely to reduce the emotional discomfort of excluding buyers.
In the wild
HubSpot considered serving both small-business owners and mid-market marketers, then chose a clearer mid-market persona. For its initial CRM, the company also examined which cohorts retained best, using actual behavior to decide who the product should initially serve. The target evolved as the product became more sophisticated.
→ The company gained a focused basis for product, marketing, and competitive decisions.
Common mistakes
Serving Every Buyer
Optimizing for every person willing to pay fragments the product and weakens the experience for the customers who matter most.
Avoiding the Hard Choice
Founders often broaden the target to reduce perceived risk, but this removes the specificity required for differentiation.
Ignoring Retention Quality
Acquisition volume can distract horizontal companies from the smaller cohort demonstrating the strongest durable fit.
Is it for you?
Best for
It is best for startups with multiple possible buyer personas, messy road maps, or weak differentiation against competitors.
Not ideal for
It is not ideal for mature portfolio companies that deliberately operate separate products and teams for distinct customer segments.
From the transcript
“who you serve is the person that you most want to buy your product”
“it's also where you win right I think this is like who you serve where you win”
“you cannot be differentiated if you are not very specific on who you serve because who you serve facilitates the differentiation”
