How to choose your first ICP when your product could sell to everyone
A simple, data-backed way for early-stage B2B founders to compare industries and pick the first ideal customer profile to focus on.

Key takeaways
- If a product can sell to many industries, picking one first ICP makes sales, marketing and product decisions much easier.
- Compare candidate industries on the same few criteria: how painful the problem is, ability to pay, how easy they are to reach, sales-cycle length and existing proof.
- Use outside data to test the founder’s instinct. The goal is to confirm or challenge a hunch before spending money on it.
Why does an early-stage company need a single ICP?
An ideal customer profile (ICP) describes the type of company most likely to buy, succeed with and stay with your product. Early on, a narrow ICP lets you write sharper messaging, build a focused outreach list and learn faster, because every conversation teaches you something about the same kind of buyer.
Horizontal products make this hard. An AI tool for marketing websites, for example, could reasonably sell to SaaS companies, agencies, staffing firms, professional services and manufacturers. Each of those buyers has different problems, budgets and buying processes.
What criteria should you use to compare industries?
Score each candidate industry on the same short list so the comparison is fair:
- Pain: how costly is the problem for them today, and do they already spend money trying to solve it?
- Ability to pay: do typical companies in this industry have budget for a tool like yours?
- Reachability: can you find and contact decision-makers easily, for example through LinkedIn or industry communities?
- Sales cycle: will a deal take weeks or many months?
- Proof: do you already have customers, pilots or warm conversations in this industry?
Where does the data for the comparison come from?
Useful sources include LinkedIn company and job-title searches to estimate how many reachable buyers exist, competitors’ customer logos and case studies to see where demand is already proven, review sites such as G2 to see which industries complain about the problem, and job postings that mention the workflow your product replaces.
Put the results side by side in one table. The point is not a perfect score but a clear, shared view of the trade-offs.
How do you validate the choice before committing?
Run a small, focused outreach test into the top one or two industries with messaging written specifically for them. Reply rates, the questions prospects ask and how quickly conversations move will tell you more than any spreadsheet.
What this looked like for a B2B AI SaaS company
ZipTier builds an AI sales rep for B2B marketing websites, and its founders had a view on which industries to target first. We ran an industry comparison alongside a market overview, a competitor landscape and LinkedIn-based outreach suggestions.
“The ICP industry comparison was the most useful part. It validated the direction we were already leaning and gave us external data-backed confidence.”

Frequently asked questions
What is the difference between an ICP and a buyer persona?
An ICP describes the type of company you should sell to. A buyer persona describes the individual person inside that company who makes or influences the decision.
Can you change your ICP later?
Yes. Your first ICP is a starting point for focus and learning. Many companies widen or shift it once they have proof in the first segment.
How many industries should you compare?
Usually three to six. Fewer than three gives you little to compare, and more than six makes the analysis slow without adding much.
