Earlyproof runs personalised outbound that books user interview slots with cold, ICP-fit prospects — people who have no reason to be polite. By testing different audiences, messages and CTAs, you get a real signal on whether your problem is worth solving — in weeks, not months.
We'll map your ICP and propose your first interview campaigns.

That's not the same thing.
You've done what founders are told to do. You talked to people. Everyone said the problem sounded real. But those were warm contacts — people who wanted to be helpful, not buyers who needed a solution badly enough to pay.
Real validation only comes from a stranger with a real problem, a budget, and no reason to say yes — who said yes anyway.
Finding that stranger without a system takes months. Most founders give up before they find enough of them. Earlyproof is the system that finds them for you.
You tell Earlyproof who you think your customer is. You don't need certainty — the whole point is to test. Pick 2–3 hypotheses: a VP of Sales at a Series B, a solo consultant, a Head of RevOps at a scale-up. Each one becomes a parallel campaign.
Earlyproof builds the prospect list for each hypothesis, writes personalised outreach asking for a 20-minute conversation (no pitch, just questions), and runs multi-touch sequences. Campaigns below 1% reply rate after 500 sends stop automatically. Campaigns getting replies get more budget.
Interview slots appear in your calendar. Every reply — yes, no, wrong person — is signal. After 2–3 weeks you know which ICP responded, which angle worked, and what objections came up. That's the answer investors are asking you to produce.
Three operating principles keep your validation honest, fast, and safe.
Run up to 4 campaigns simultaneously — different customer types, angles, buying signals. The hypothesis that books the most interviews at the lowest cost per conversation is your beachhead. You'd otherwise spend three months testing them one at a time.
Reply rate, objection patterns and campaign performance are logged per hypothesis. You're not just booking interviews — you're building a map of who your customer is and what message resonates with them.
Bounce rate and spam complaint rate are monitored per inbox per week. Hard limits stop campaigns before they damage your sending domain. A burned domain costs 4 weeks of lost pipeline. Earlyproof prevents it before it happens.
Apollo + hand-written sequences vs. a validation system that's been run before.
