One guided conversation in Claude. HubSpot's GTM expertise, original research, and a proven development framework built into every question. A complete ICP your sales, marketing, and CS teams can work from today.
The ICP Builder draws on HubSpot's original ICP research, including data on where most teams fall short so you can ask better questions and flag gaps before they become targeting mistakes.
Only 19% of marketers involve sales, CS, and product in ICP development. This one is built for all of them, with account tiers for sales, activation playbooks for marketing, and churn signals for customer success baked into the same document.
The ICP Builder pushes back. If your criteria are too narrow, too broad, or unvalidated, it flags it and asks you to defend it — so you leave with a profile that holds up in the field, not just one that looks complete on paper.

Your ICP is only as useful as the decisions it drives. If your sales team isn't using it to qualify, your marketing team isn't using it to target, and your CS team isn't using it to flag risk, it's not an ICP. It's just a document.
The ICP Builder is a free Claude skill trained on HubSpot's go-to-market expertise, original ICP research, and a proven development framework. In 15 minutes, it produces a complete ICP document built from real methodology, not a template someone filled in once and forgot about.
Bring what you know. Leave with something your whole team can use.
