How Do You Pick an ICP When Two Segments Both Buy?

What do you do when two customer segments both buy?

Pick one to focus on for the next two quarters and treat the other as opportunistic. Compare them on win rate, sales cycle, deal size, retention, reachability, and proof. The right ideal customer profile is the segment you can win again and again with the channels and evidence you already have.

This is a good problem, and it still stalls teams. A founder closes a few consultancies and a few in-house marketing teams. Both paid. Both renewed. Now every decision splits in two: the homepage headline, the outbound list, the case study you write next, the integrations you build.

Trying to serve both feels safe. In practice it halves your message, your proof, and your pipeline math. Below is how I would make the call, using numbers you can pull from your CRM this week, plus the parts of the decision that numbers will not settle for you.

Why is serving two segments at once so expensive?

Because every go-to-market asset has to pick a reader. A homepage, a cold email, a case study, and a pricing page each work best when they speak to one buyer's problem in that buyer's words. Two segments means two of everything, or one blurred version that speaks clearly to neither.

The cost shows up first in messaging. A consultancy owner worries about margins and client churn. An in-house marketing lead worries about headcount and reporting to a CFO. One headline cannot carry both worries without going vague, and vague headlines are the ones nobody remembers.

It shows up next in the stack. Your outbound list in Apollo or Clay needs different filters. Your lead score in HubSpot needs different signals. Your sequences need different proof. Each split doubles the work for a small team and halves the learning, because each version gets half the volume it needs to show a pattern.

Which six factors should decide your ideal customer profile?

Compare both segments on six factors: win rate from qualified opportunity, length of the sales cycle, average deal size, retention and expansion, cost to reach the buyer, and the strength of proof you already hold. Score each segment honestly, then weight reachability and proof highest when the team is small.

Win rate tells you where your product already fits. Pull every qualified opportunity from the last twelve months, tag each by segment, and count closed-won against closed-lost. Small samples are noisy, so look for a clear gap, not a decimal point. If both segments win at similar rates, move on to the other factors.

Sales cycle and deal size together tell you cash speed. A segment that closes in three weeks at a modest price can fund growth faster than one that closes in five months at double the price. For a bootstrapped team, cash speed often matters more than the size of any single deal.

Retention and expansion tell you whether the win lasts. A segment that churns after one year makes every acquisition cost look worse in hindsight. Check renewals, downgrades, and add-ons by segment in HubSpot or Salesforce. If you are too young to have renewal data, use product usage as an early signal.

How do you measure reachability for each segment?

Reachability is how cheaply you can get in front of a qualified buyer, more than once. Test it by building a list of one hundred target accounts per segment and checking how many have a findable decision maker, a clear channel, and a reason to care right now. The cleaner list usually wins.

Build both lists the same way. Use LinkedIn Sales Navigator, Apollo, or a Clay table with the same filters you would use for real outbound. Then count what you can actually act on. How many accounts have a named owner for the problem? How many have a verified email? How many show a trigger, like a new hire or a funding round?

Then look beyond outbound. Does the segment gather in one community, read one newsletter, or attend one event? Consultancies often cluster in partner programs and founder communities. In-house teams can be harder to find as a group. A segment you can reach through two or three dense channels beats one you must hunt account by account.

Why does existing proof matter so much?

Proof shortens every sales cycle you will run next. A buyer trusts a case study from someone who looks like them far more than a general claim. If one segment already has a named customer willing to talk, a clear before and after, and a quote you can use, that segment starts several months ahead.

This is the factor founders underrate most. They pick the segment with the bigger theoretical market and then spend six months unable to show a single relevant result. Meanwhile the other segment, the one with three happy customers who would take a reference call, sits unused.

This is how I think about my own practice too, after 100+ projects for 25+ clients over six years. The most useful proof is a result a similar buyer can recognize. Proof compounds inside a segment. It barely transfers across segments.

What if the numbers point in different directions?

They often will. One segment wins more often while the other pays more. When the factors split, weight them by your constraint. A cash-tight team should favor speed and win rate. A team with runway and a strong product can favor deal size and retention. Write down the constraint before you look at the scores.

A simple scoring sheet in Google Sheets helps here. List the six factors as rows and the two segments as columns. Give each cell a score from one to five, with a sentence explaining the score. The sentences matter more than the scores, because they show where you are guessing.

Then run one sanity check that numbers miss. Ask which segment your team actually enjoys selling to and understands without effort. Conviction shows up in sales calls. A founder who deeply understands consultancy economics will outsell the same founder pitching a CFO they find confusing, even if the CFO segment scores slightly higher.

What happens to the segment you do not pick?

Keep serving it, but stop investing in it. Existing customers still get great support, and inbound leads from that segment still get a fast reply. What stops is proactive spend: no new outbound lists, no new case studies, no product work built only for them, until the focus segment is working.

Write this down as a rule, not a mood. In HubSpot, tag the segment so you can report on it separately. Route its inbound leads normally, but do not count them toward the focus metrics. If that segment keeps growing on its own, it may earn a second look in six months, with real data behind it.

This is also how you avoid the slow drift back to serving everyone. A clear tag and a clear rule make it obvious when someone starts building a deck or a sequence for the non-focus segment. The question becomes simple: is this worth pulling time from the segment the team chose?

How do you know if you picked the wrong segment?

Set a test window and two leading indicators before you start. A good window is one to two quarters. Watch meeting-to-opportunity rate and the length of the first sales cycles in the focus segment. If both stay worse than the segment you parked, you have learned something real and can switch with confidence.

The point of picking is not to be right on the first try. It is to learn faster than you could by splitting effort. A focused quarter gives you clean data: one message, one list, one set of objections. Even a failed test teaches more than a split quarter where nothing reached enough volume to read.

Before you commit, it helps to check whether your current definition is too wide. I wrote about the warning signs in signs your ideal customer profile is too broad, and if you are still early, how to define an ICP when you have twenty customers covers the step before this one.

What should you do next?

Pull your last twelve months of opportunities, tag each by segment, and score both segments on the six factors this week. Write your main constraint at the top of the sheet. Then pick one segment for the next two quarters, tag the other, and tell your team the rule in one sentence.

Once the choice is made, the next job is turning it into a target list. My guide on how to tier target accounts for a small sales team picks up exactly there. The segment choice tells you who. Tiering tells you which accounts get attention first.
