How Many ICPs Should Your Business Actually Have?

Once the first ICP is written down, a second question shows up fast: do we need one for every product, every segment, every persona that shows interest? Usually not — but the honest answer is more nuanced than a flat "just one."

The case for one

A single ICP forces discipline. Every message, every ad, every piece of content can be built for one specific buyer instead of watered down to work for everyone a little. Most early-stage teams that struggle with generic messaging are really struggling with an ICP that quietly became three.

When more than one is legitimate

Sometimes a company genuinely serves two structurally different buyers with different pain profiles — not just different demographics. We saw exactly this in the solar case study: homeowners and mandate-bound developers weren't really two flavors of the same customer, they were two different problems wearing the same industry label.

Multi-product companies run into a related version of this — each product can have a genuinely distinct ICP if it solves a different problem for a different buyer, even inside the same company.

The trap: using "multiple ICPs" as an excuse to stay broad

Teams that can't commit to one often end up with three or four "ICPs" that are really just the target market restated in smaller pieces — see the difference laid out in ICP vs Buyer Persona vs Target Market. If none of them would disqualify most of your current pipeline, they're not really ICPs yet.

A simple test: rank and pick a primary

Even with two or three legitimate segments, rank them by severity, frequency, and cost of inaction — the framework from our core ICP guide — and let the highest-scoring one drive your GTM sequencing. The others can stay documented and revisited later, but only one should be getting the bulk of the budget and messaging at a time.

Once you've picked a primary, the ICP template and
