7. Redefine your ICP based on who actually buys, not who you hope will.

For Marketing & Sales

Most ICP exercises answer one question: who do we want to work with? The 2026 data points to a more useful one: who actually completes a purchase, and why?

The differences between completed and failed evaluations in the 2026 data are striking. Completed purchases are far more likely to involve experienced buying groups, proactive triggers, and buyers who already had prior familiarity with the winning vendor. Failed evaluations are far more likely to involve less experienced groups, reactive triggers, and buyers who never fully aligned on the category case.

These patterns describe a profile of buyer, trigger, and context that is far more likely to result in a closed deal. Most ICPs are built from aspiration and instinct.

This one can be built from evidence.

Pull your last two years of closed-won deals and look for the patterns your current ICP does not capture: what triggered the evaluation, which roles were involved, how experienced the buying group was, and what the buyer already knew about you before first contact.
Do the same for your closed-lost deals. Look for structural differences, not just competitive losses. Were the buying groups less experienced? Were the triggers reactive? Was the category case never made?
Ask honestly: in which accounts does your brand already have a footprint, and in which are you starting from zero? The former is almost always more actionable than the latter.
Revisit your ICP at least annually using actual outcome data. An ICP that is never updated by what actually closed is not a strategic tool. It is a comfort document.
Make sure both marketing and sales are targeting the same accounts based on the same ICP. An ICP that lives only in a strategy deck and never changes a targeting decision has no commercial value.
