How to ask someone to refer you for a job
The hard part is deciding whether you know this person well enough to ask. The people who move jobs for you are usually the ones you feel least sure about.
By Jerry Feng, Growth at Happenstance. Updated August 28, 2026.
The short version
Write to the person who saw you work rather than the person you feel closest to: a five-year experiment on LinkedIn covering 600,000 job changes found that moderately weak ties, not close friends, are the ones that lead to new jobs. Say in the first line how long it has been since you spoke. Reopen the conversation and make the ask in the same message, because a week of manufactured small talk before the request is the part that reads badly. Give them a smaller favor they can offer instead of a referral. Treat a no, and a silence, as the same finished answer.
What the LinkedIn experiment found
In 2022, Science published a study by Karthik Rajkumar, Guillaume Saint-Jacques, Iavor Bojinov, Erik Brynjolfsson and Sinan Aral that ran on LinkedIn's People You May Know algorithm. The experiments “randomly varied the prevalence of weak ties in the networks of over 20 million people over a 5-year period, during which 2 billion new ties and 600,000 new jobs were created” (Science 377, September 15, 2022). The result was “an inverted U-shaped relationship between tie strength and job transmission such that weaker ties increased job transmission but only to a point, after which there were diminishing marginal returns to tie weakness”.
In plain terms: the closest friends were not the ties that led to new jobs, and neither were the strangers. The moderately weak ties were, meaning people you have a real history with and have not spoken to in a while. That is the band most people feel awkward writing to, and the experiment measured it across 600,000 job changes.
Sorting the people you could ask into three bands
Write down everyone you know at the company, then sort them by two questions: did they watch you work, and when did you last talk.
The first band is people you worked with directly and have messaged in the last year. Ask them plainly; the message is short because the context is shared. The second band is people you worked alongside for a year or more and have not spoken to in over a year: the manager two roles ago, the engineer from the team next door, the colleague you liked and lost touch with. This is the band the experiment points at. The third band is friends who never saw you work. They can tell you who owns the role and whether the requisition is real, and that is the smaller favor to ask them for.
A referral at most companies is a short internal form plus a small amount of the referrer's standing if you turn out to be nothing like the description. Both get cheaper when the ask stays inside what the person saw, which is why the second band works: they can defend what they say about you to a recruiter who asks a follow-up question.
Two messages, by how long it has been
What separates these is how much of the message goes on establishing what the person can honestly say about you, and whether the first line names the gap.
Template 1: somebody you've spoken to this year
Subject: Would you refer me for [Staff Engineer, Infrastructure]?
Template 2: somebody you haven't spoken to in years
Subject: Out of the blue, and about a job at [Company]
Treat a no and a silence as the same finished answer. Reply to a no in one line and ask nothing further about the job. Don't raise it if you meet later. Send nothing after a silence, because a second message forces somebody to write the refusal they were hoping to avoid. Then go to the next person in the band, or apply on your own.
Once somebody has said yes, what to send them next is on how to ask for a referral for a job. If you have nobody at all at the company you want, getting a referral at a company is the sourcing version of this problem.
Finding where the middle band went
The second band is hard to list from memory, because reconstructing where a decade of colleagues ended up means paging through old mail. Happenstance reads the accounts you connect, Gmail, Outlook, Google Calendar, Google Contacts, LinkedIn, Twitter and Instagram, and answers questions about them. Ask “Where do the people I worked with at Loop work now?” and the answer is your former colleagues by current employer, each with how well you know them and which account the relationship came from, which is the evidence for which band they belong to. Happenstance is free. The free plan is the whole product, with usage limits on chat and web searches beyond your network. Pro raises the limits: unlimited web searches and results, higher chat limits, and CSV export.
Mutual connections covers the other direction, the people you and a target share, and Happenstance for job seekers is the wider version of the search.
What Happenstance can see
Email is read as headers only. Message content and attachments never reach our servers. Yes. Your connections are searchable only by you, the friends you accept, and the groups you join, and sharing is always mutual. Your public profile shows a constellation of named people you know by default, which you can turn off anytime. We never share, sell, or use your data to train AI models.

Frequently asked questions
Is it rude to ask someone to refer you for a job?
It's rude to ask somebody to claim something they didn't see. It isn't rude to ask a person who worked with you to say that they worked with you. The line between the two is what they can defend if a recruiter asks a follow-up question, so keep the request inside what they witnessed and the social cost mostly disappears.
How do I ask for a referral from someone I haven't spoken to in years?
Name the gap in your opening line rather than writing around it. Something like "we haven't spoken since Loop, so this is out of the blue" costs you one sentence and removes the thing the reader is already thinking. Then make the ask in the same message. Reappearing with friendly small talk and returning a week later with the request is the version people resent.
Should I warm someone up before asking for a referral?
No, if the warm-up exists only to set up the ask. People can tell, and it converts an honest request into a maneuver they now have to be polite about. If you want to catch up, catch up and don't mention the job. If you want the referral, ask for the referral and be plain that it is why you wrote.
What do I say if they say no?
Say thank you, ask nothing else about the job, and mean it. A useful reply is one line: "Completely understood, thanks for telling me straight." Don't offer to send more information, don't explain why you'd have been a good referral, and do not come back to it in a later message. The people who take a no cleanly are the ones who get asked back.
What if they never reply?
Send nothing further. A referral request that goes unanswered has been answered, and a second message forces somebody to write a refusal they were hoping to avoid. Go to the next person on your list or apply on your own, and if you meet the first person later, don't raise it.
Do I owe someone anything for referring me?
You owe them the ending. Tell them what happened, whether you got the interview, the offer, or nothing, and tell them before they hear it from a recruiter. Cash and gifts are the wrong currency and can breach a company's referral policy. Being the person who closed the loop is what makes the next request easy.
