How to draft an ICP definition for startups

An ICP definition for startups is your written ideal customer profile: a short, shared statement of who you sell to first, what context they work in, and which outcomes justify a purchase. In Nautis that lives in GTM Planner: the Builder Customer step drafts it, and the Strategy tab Ideal Customer Profile section is where you keep the lasting version. Strategy also holds Positioning, Value Stack, Messaging, Risks & Considerations, and Competitor Analysis beside Ideal Customer Profile. Fill Ideal Customer Profile first so those sections have a buyer to talk about. Without that order, Positioning becomes a slogan contest with no Ideal Customer Profile underneath it.

This post is about writing and locking that definition. It is not a full 30/60/90 roadmap walkthrough. Roadmap and Tasks come after the Ideal Customer Profile is clear enough that outreach does not invent a new buyer every week. The published 30-60-90 GTM guide covers phase timing. Here the job is only the buyer definition those phases assume.

Why an ICP definition for startups has to be written down

Verbal ICPs drift. Sales describes one buyer, product another, and ads a third. A written Ideal Customer Profile in one GTM workspace becomes the reference before you spend on channels.

Illustrative miss (composite only): three founders pitch "mid-market ops leaders" while inbound forms fill with students and hobbyists. Illustrative fix (composite only): Ideal Customer Profile names a role, company band, and outcome; inbound form copy matches that role within a week.

Keep one primary ICP per workspace. Use another workspace if a second product line needs a different buyer. Mixing two unrelated buyers in one Ideal Customer Profile section produces vague Messaging and useless Experiments. Split early rather than averaging two buyers into mush that nobody can sell.

Open GTM Planner and create a workspace

From the sidebar open Strategy & Planning, then GTM Planner. On GTM Workspaces click New Workspace. Enter a Workspace name, pick Shared Access teammates, click Create Workspace. You land on the Strategy tab. Tab bar options include Dashboard, Builder, Strategy, Roadmap, Tasks, Experiments, and Metrics. Use Back to Workspaces to return to the list. Stay on Strategy until Ideal Customer Profile is specific enough that a new teammate could qualify inbound without asking you.

Workspace cards show status (Not Started, In Progress, On Track, Needs Attention), a health score out of 100, the current 30 / 60 / 90 phase, and created date. Only people on Shared Access (plus admins) can open the workspace. GTM permission must be enabled for your role, and the module must be on for the organization. Rename or change Shared Access from the pencil icon on a workspace card, then Save changes. Search filters the workspace list by name.

Illustrative create (composite only): Workspace name "2026 SMB Launch"; Shared Access founder plus one AE. One workspace equals one go-to-market plan. Split product lines into separate workspaces instead of stacking conflicting Ideal Customer Profile text in one canvas.

Draft the buyer in Builder, then lock Ideal Customer Profile

Open the Builder tab for a guided pass. The nine steps start with Customer (who you sell to first), then Problems, Solution Mapping, Value Stack, Positioning, GTM Execution, Competition, Risks, and Launch Plan. Use the AI Draft bar on a step when you want suggestions, edit the text, and save so the step turns green. AI Rewrite polishes a single field. Progress fills as steps save. You still own every sentence that remains after you apply Full Strategy. AI Draft, AI Rewrite, and related Builder AI use organization AI credits. You can skip Builder and type Ideal Customer Profile by hand on Strategy if you already know the buyer. Both paths edit the same strategy data. Builder is faster for a first pass; Strategy is better for ongoing edits once Shared Access agrees on the buyer.

When the draft is good enough, open Full Strategy and apply it so Strategy updates. Then open the Strategy tab and select Ideal Customer Profile in the left rail. Edit who you sell to, their context, and outcomes with the inline inputs. Changes save automatically. Export a PDF from the strategy PDF control when you need an offline copy. Trash icons on Strategy entries ask for confirm before delete. Prefer edit in place when only one phrase is wrong.

Illustrative path (composite only): Builder Customer draft in ten minutes; apply Full Strategy; tighten Ideal Customer Profile by hand the same afternoon.

Illustrative must-haves (composite only): VP Operations at 50-200 person B2B firms on Salesforce; outcome "cut weekly inventory fire drills"; disqualify agencies and sub-10 person shops. Optional rows wait until the must-have row is stable for a few weeks of conversations. Do not block shipping the definition on perfect competitor research. Geography on Positioning should match the countries you listed as must-have. Wishlist regions stay out of paid campaigns until you staff them.

Align Positioning and Messaging to the same buyer

Still on Strategy, open Positioning for the one-line statement, target countries, market category, and differentiation. Open Messaging for pain points matched to solutions. Open Value Stack for features and value propositions with descriptions. If Ideal Customer Profile says ops leaders and Positioning speaks only to CFOs, fix the mismatch before Roadmap work. Dashboard shows an ICP summary in the strategy snippet. If that snippet disagrees with what AEs say on calls, update Strategy before you trust health score alone. Health score blends completed Tasks and recent Metrics snapshots. It will not fix a wrong Ideal Customer Profile. Fix the buyer text first, then chase green health.

Competitor Analysis entries need name, their solution, and their positioning. Risks & Considerations need title, impact (High / Medium / Low), type (Execution, Technical, Financial, Marketing), and mitigation. Those sections support the ICP; they do not replace it.

Illustrative align (composite only): Positioning one-liner names the same role as Ideal Customer Profile; Messaging pains mirror the Problems Builder step.

Use the ICP before Roadmap, Tasks, and Leads & CRM

Roadmap phases (30 / 60 / 90 days) and Convert selected into the Tasks board (Backlog, This Week, In Progress, Done) assume you already know the buyer. Experiments and Metrics should name channels and measures that fit that Ideal Customer Profile. On Experiments, hypothesis, Channel, Phase, and Metric should assume the same buyer. AI Suggest proposes tests from strategy and uses AI credits. Reject suggestions that target a role your Ideal Customer Profile never named.

When you create sales pipelines in Leads & Sales CRM, name stages for the process that serves this ICP, not a generic funnel copied from a template blog. Create Pipeline, add leads on the Kanban, and keep Investor CRM separate for fundraising contacts. Leads & CRM is under Marketing in the sidebar. Verify email before the first pipeline if the product requires it. Create Lead and Create Pipeline need the matching permissions.

Illustrative handoff (composite only): ICP locked Monday; Roadmap Week 1 tasks are interviews with that role only; Leads pipeline "SMB Ops" uses stages that match that motion. Default pipeline stages are editable later. Name the pipeline for the ICP motion so Shared Access does not dump unrelated leads into it. Mark one Default Pipeline only when new leads should land there automatically.

Review the ICP when evidence changes

Reopen Ideal Customer Profile when win/loss notes show a different buyer, when Dashboard strategy snippet looks stale, or before you add a second workspace for a new segment. Prefer hand edits on Strategy for small updates; use Builder when you need a full rewrite. After a rewrite, re-check Positioning and Messaging the same day so the canvas stays internally consistent.

Illustrative review (composite only): after ten calls, context band shifts from 50-200 to 100-500; update Ideal Customer Profile and Positioning countries the same day; leave Roadmap tasks that still fit.

When you retire an ICP, archive tasks that only made sense for the old buyer instead of leaving them In Progress as noise on the health score.

An ICP definition for startups works when Shared Access can open one workspace, Ideal Customer Profile states who/context/outcome without jargon, and paid outreach waits until the must-have row of the attribute gate is filled. Revisit the attribute gate whenever you change primary channel or pricing on Strategy so GTM Execution still matches the same Ideal Customer Profile. If GTM Execution lists channels your Ideal Customer Profile never uses, cut the channel or widen the Ideal Customer Profile on purpose, not by accident.
