Sample BuyerPersona
Growth-stage infrastructure companies (Series B–C) that are actively hiring operators and struggling with handoff chaos.
Responsible for scaling processes. Value clarity, speed, and tools that reduce manual coordination.
Why start with the buyer, not a lookalike
A lookalike search finds companies that resemble your customers. That list includes your competitors, and companies with no reason to buy. A BuyerPersona starts from the other end: the titles who feel the problem, the pains in their own words, the trigger events that make them look, and the disqualifiers that rule a company out. Every lead is then scored against it, with the reasoning shown.
Read why lookalike targeting sends you to the wrong buyers, or see how the persona is used by founders and by a first sales hire.
Questions about the ICP generator
What is a BuyerPersona?
A model of who actually buys from you: pains, trigger events, and disqualifiers. It is not a company-size or title filter, and not a lookalike embedding. Rainmaker builds it from your URL and scores every lead against it before a draft is written.
Is the ICP generator free?
Yes. Enter a company domain and the preview runs with no signup.
Is the preview the real output?
It is a preview. The Reader and Scorer models run on the domain you enter, with illustrative leads and guarded sample copy. The full product produces editable BuyerPersonas that drive real prospecting.
How is a BuyerPersona different from lookalike targeting?
Lookalike models return companies that resemble your existing customers, which often includes competitors and non-buyers. A BuyerPersona models who buys and why, and every lead is scored against it with the reasoning shown.
The real version lives in the product
