How to recruit users for customer interviews on LinkedIn

To recruit customer interviews on LinkedIn, pick a small, precise group of users from your analytics, send each a short personal ask that says why them, and put one booking link in the reply. Keep the ask under 20 minutes and answer fast when they say yes.

LinkedIn works well for this because the ask comes from a person, not a product email. Here is the method, the messages, and how to run it without spending your week in the inbox.

Choose who to talk to before you write anything

The best interviews come from people with a specific, recent experience. Pick one group per round:

Group	What you learn	Where to find them
Signed up, never activated	What blocked the first step	Your analytics (PostHog, Mixpanel)
Active power users	What they would never give up	Your analytics, your customer list
Churned in the last 60 days	Why they left	Billing tool or analytics cohort
Ideal customers who never tried	How they solve the problem today	LinkedIn search or signals

Ten interviews in one group teach you more than ten spread across four.

Get the list into your outreach tool

You need each person’s LinkedIn profile URL. If your product doesn’t store it yet, add “Sign in with LinkedIn” or ask for it at signup, or run your export through an enrichment tool.

In Reachy, you don’t need to export by hand every time. A list can stay in sync with:

• A PostHog cohort, read with a read-only API key
• A Google Sheet shared by link
• A CSV or Excel file on your computer
• The members of a Slack channel, for community-led products

Reachy checks the source every day and adds new people, so “users who churned this month” stays current. You choose what happens when someone leaves the source, and people Reachy already contacted keep their history.

The message: why them, what you want, how long

Keep it under four lines. Say why you picked them, what you are asking, and how long it takes. No pitch.

For users who never activated:

Hi Sam, I’m the founder of [product]. You signed up in September and I’d love to understand what got in the way. Would you have 15 minutes for a call? No sales, just questions.

For power users:

Hi Ana, you’re one of the people who use [feature] the most. We’re deciding what to build next and your view would help a lot. Up for a 20-minute chat this week?

For churned users:

Hi Tom, I saw you stopped using [product] last month. No hard feelings, I just want to understand what we missed. 15 minutes, and I’ll send you [incentive] as thanks.

The reply: one link, same day

When someone says yes, answer within the hour with the booking link and nothing else. Every hour of delay costs interviews.

This is where Reachy’s AI replies help. Put your interview booking link in the AI replies context instead of a sales call link. When someone answers “sure, happy to help”, Reachy drafts the reply with the link and sends it to your phone on Telegram, Slack or Discord. You tap Send.

Replies that need you, like “what’s this about exactly?” from someone suspicious, are marked “Over to you” and left alone.

After the interview

• Thank them the same day, on LinkedIn, in one line
• Tell them what changed because of their feedback, when it ships
• Keep the list: these people are your best beta testers

Checklist

• One group per round, chosen from data
• LinkedIn URLs in the list
• Ask under four lines, with a time limit
• Booking link ready before you send anything
• Same-day reply to every yes
