The ideal customer profile on one page

An ideal customer profile is not a persona with a stock photograph. It is a filter an SDR can run against a list on Monday without calling you: this company yes, that one no, and why.

An ideal customer profile is not a persona with a stock photograph and a first name. It is a filter an SDR can run against a list on Monday morning without calling you: this company yes, that one no, and here is why. If two people on your team would disagree about whether an account qualifies, you do not have one yet.

This lesson separates the three documents founders confuse, segment, ICP and persona; sets out firmographics in Indian terms; adds the triggers that say this quarter rather than someday; gives the disqualifiers their proper half of the page; builds the one-pager in a figure; and ends with the Monday test that tells you whether it is finished.

Segment, ICP, persona: three documents, not one

The [segment](/library/segmentation-that-changes-what-you-build) is the set of people who share a behaviour and a buying trigger; it is the output of twenty interviews and it lives in the customer’s words. The persona is the human inside the account, with their fears and their calendar; Rahul Vohra’s profile of Superhuman’s high-expectation customer, “Nicole is a hard-working professional who deals with many people”, is the type done well. The ICP sits between them and does a different job: it translates the segment into traits that can be checked from outside before anyone is called.

Pete Kazanjy’s Founding Sales makes the distinction that matters for a B2B company: the ideal customer is an organisation, not an individual, and contacts come later. The profile is a set of observable characteristics that signal the organisation has the pain your product addresses, with hard minimums he calls required characteristics; his example is that a product needing Gmail and Salesforce rules out every account without both. His warning is the one founders most need: targeting based on relationship rather than need is ineffective and a waste of time. The companies you can get a meeting with are not the ICP. The companies with the pain are.

Firmographics, in Indian terms

Size, in two measures. Headcount, read from LinkedIn, the careers page and the office, is the number that predicts whether a process has broken. Turnover, where it matters, is best stated in the bands the government uses: under the MSME classification notified in March 2025 and in force from 1 April 2025, a micro enterprise has investment in plant, machinery or equipment up to ₹2.5 crore and turnover up to ₹10 crore, a small enterprise up to ₹25 crore and ₹100 crore, and a medium enterprise up to ₹125 crore and ₹500 crore (checked October 2026). The bands matter because many buyers describe themselves in them, because Udyam registration is public, and because a registered MSME supplier has statutory protection on payment timelines, which changes how your own invoices get paid.

Legal form: a private limited company or LLP buys differently from a proprietorship, which is usually the owner’s personal decision and personal UPI. Geography by city and not state, because onboarding, support and the walk-in all have a radius. Industry by behaviour, not by code: “runs a two-shift plant” says more than any NIC classification. Systems in use: a desktop accounting package, spreadsheets and WhatsApp, a legacy HRMS, a billing tool with an inventory tab; what the company has already hired tells you what it will fire. Stage: DPIIT recognition, a seed round announced, a new director appointed, all visible on the MCA register and LinkedIn. Each trait must be observable or answerable in one question, and Kazanjy’s point holds for the ones that are not: a hidden characteristic still belongs on the page, as a discovery question rather than a list filter.

Triggers: the signals that say this quarter

Firmographics find the companies that could buy. Triggers find the ones that will buy this quarter, and they are the hiring moments of the [jobs lesson](/library/jobs-to-be-done-job-customer-hires-you-for) seen from the outside. A job post for a specific role is the most reliable: a company advertising for a purchase manager has a purchasing problem it has priced at a salary. A second location, visible in a Google Maps listing or a LinkedIn post. A funding announcement, which comes with a hiring plan and a board. A regulatory date that lands on everyone in the segment at once. A new function head, who has ninety days to change something. A public complaint on a review site or a trade group. A tender, for the segments that buy through them.

Kazanjy calls the same things demand signals: the number of people in the relevant role, hiring activity, and evidence the company already pays for related tools. The rule for the page is that one trigger must be live for an account to be called. Accounts that fit every firmographic and show no trigger are parked and re-checked monthly, not dialled. This single rule is the difference between a team that closes one in four conversations and one that closes one in twenty-five.

Disqualifiers: the half of the page that saves the week

Every ICP founders write is a list of must-haves. The half that does the work is the list of reasons to say no, because a good-looking account that fails one disqualifier will consume a week of demos before it fails, and Kazanjy’s instruction is to stop spending time on unqualified prospects even when they arrive inbound. The usual disqualifiers for an Indian B2B company: the wrong size band on either side; an in-house team or outsourced provider already doing the job well enough; a government body or public-sector unit, which means a tender; a procurement cycle longer than ninety days or a requirement for on-premise deployment; an existing contract with a lock-in; a buyer who cannot be reached without an introduction; a location outside the radius you can onboard this week; and a payment practice that will not clear an invoice inside thirty days.

Write them as sentences an SDR can check, not adjectives. “Not a good fit culturally” is not a disqualifier. “Has posted a tender for this category in the last two years” is.

The ideal customer profile is a list of reasons to say no, with the yes left over.

A worked example: the attendance tool

Return to the founder from the [interview lesson](/library/the-customer-interview-done-properly) who discovered that the payroll problem in thirty-person Pune agencies was really attendance and leave data arriving late from managers. Twenty interviews and a first segment later, the ICP fits on a page. Must-haves: private limited company or LLP, 50 to 200 employees across at least two managers’ teams, in Pune or Mumbai, running attendance on spreadsheets and WhatsApp with payroll in a desktop accounting package or at a part-time accountant. Trigger, one of which must be live: five or more open roles posted in the last ninety days; a second office or site opened in the last six months; a PF or ESI inspection or payroll audit in the last quarter. Buyer: the HR head or office manager who owns the month-end chase, with the founder as signer; first qualifying question, how many attendance disputes reached you last month. Disqualifiers: under 20 or over 1,000 employees; a shared-services centre or outsourced payroll vendor; a government body; on-premise or a ninety-day procurement cycle; outside the onboarding radius. Where found: LinkedIn Jobs filtered by city and company size, Google Maps for new offices, the CA network for the compliance trigger.

Read the page and notice what it does. It excludes the thirty-person agency from the original interviews, because at that size the founder still sees everyone and the pain is tolerable, which was a finding and not a failure. It gives the SDR a list source for each trigger. It tells them whom to call and what to ask first. And it has five disqualifiers that can each be checked in under a minute from a website, LinkedIn and the MCA register. A list of fifty companies becomes a list of twelve to call this week, and the twelve are the right twelve.

The Monday test, and the monthly review

The page is finished when it passes one test. Give it, with a list of fifty companies from the segment, to someone who has never met a customer, a new SDR, an intern, a friend with a free hour. Ask them to mark each company yes, no or unsure, with the line on the page that decided it. If more than one in five comes back unsure, a criterion is vague; find it and rewrite it as something observable. If the yes list is longer than Kazanjy’s working range of fifty to a hundred accounts, the page is too loose; if it is under ten, too tight for a first quarter. Run the test again after the fix. It takes an hour and it is the only review of an ICP that counts, because the SDR is who the page is for.

Then put the page under version control, literally: ICP v1 with a date at the top. On the first Monday of each month, tag the month’s wins and losses against it. Which must-haves did the losses share? Which trigger did the wins arrive through? Which disqualifier should have caught the deal that died in week five? After twenty closed deals, won or lost, rewrite the page as v2 and date it. An ICP that has not changed in two quarters is not stable; it is unread.

The MSME bands and other thresholds change; the ones above were checked in October 2026 and should be re-checked before they go on a page your team will use. Nothing here is legal, tax or investment advice.
