How to find buyers on LinkedIn with Jev
People post on LinkedIn when they need something: a CRM, an accountant, an agency. I pulled 290 of those posts and had Jev pick out the people ready to buy. Here’s the run, the exact call, and how to point it at what you sell.

What happened when I ran it
Six searches of public LinkedIn posts from the last month, worded the way buyers ask: “can anyone recommend a CRM”, “can anyone recommend an accountant”, “looking for a marketing agency recommendations” and three more. That gave me 290 posts. Jev read every one and scored whether the author is looking to buy right now.
The whole run cost $0.046, searches and profile lookups included. Of the 23 buyers, 10 wanted a marketing or ads agency, 7 wanted software, 3 wanted a website or app built, and one each wanted a CRM, an accountant and a freelancer.
How it works
One Jev call per post:
- The state is the post: the author’s name and what they wrote.
- The questions are asked together. One asks whether the author is looking to buy right now. Seven more ask what kind of thing they want, so every buyer comes with a label.
Jev answers each question with a probability from 0 to 1. Eight questions in one call cost far less than eight calls, because the post is only sent once.
New to Jev? Start with the setup guide: key, first call, working response. Then come back.
Get your keys
You need two. A Jev key to score the posts: my run called TypeSafe’s API directly, so the script reads TYPESAFE_API_KEY. The TypeSafe quick start ↗ covers getting one. If you set Jev up through Vercel in my setup guide, ask your agent to send the same questions that way.
And a Treg token to search LinkedIn posts. Treg is one key for a catalogue of data tools, billed per call. My lead list guide covers installing it.
Search the way a buyer writes
This decides what you find. Search for the words people use when they ask, not the words sellers use when they pitch. These were my six:
- can anyone recommend a CRM
- can anyone recommend an accountant
- can anyone recommend an AI tool
- looking for a marketing agency recommendations
- looking for a web developer recommendations
- looking for software recommendations
# One search. I ran six; together they cost 2 cents.
curl -s https://treg.to/call/anyapi.linkedin.search.posts.full \
-H "X-Treg-Token: YOUR_TREG_TOKEN" \
-H "X-Treg-Route-Max-Cost: 0.05" \
-H "Content-Type: application/json" \
-d '{"query": "can anyone recommend a CRM", "datePosted": "last-month", "limit": 50, "sort": "relevance"}' \
> search-1.json
# Merge every search into one list, keeping only what Jev needs
jq -s '[.[].output.data.posts[] | {author: .author.name, text, url}] | unique_by(.url)' search-*.json > posts.jsonThe six searches took a little over two minutes and cost 2 cents. Each returns up to 50 posts.
Score every post
These are the exact questions and the exact call from my run, trimmed to read posts.json and write buyers.csv.

Read the scores
I used three bands:
- 0.80 and up: buyer. 23 of my 290 posts. Read these first.
- 0.50 to 0.79: warm. 8 posts. Worth a look when the buyers run out.
- Under 0.50: not buying. Mostly people selling, giving advice or posting job ads.
Make it yours
Change the searches
Write them as your buyer would: “can anyone recommend a bookkeeper”, “who do you use for payroll”.
Change the labels
Swap the seven kinds of need for the things you sell, so every buyer comes tagged with yours.
Move the bar
0.80 gave me a short list. Drop to 0.50 when you want more to read.
The search only looks at the last month, so running it again each month gives you a fresh list.
Let an agent build it
Paste this at Claude Code or Codex. It writes buyer searches for what you sell, shows the price before it searches, and never contacts anyone.
Find people on LinkedIn who are asking for what I sell, using Treg for the posts and Jev to judge them.
1. Ask me what I sell, in one plain sentence. Then write 6 search phrases the way a BUYER would post them, for example "can anyone recommend a CRM" or "looking for a marketing agency recommendations". Show me the list before you search.
2. For each phrase, call Treg's anyapi.linkedin.search.posts.full with datePosted "last-month" and limit 50. Show me the price first. Merge the results and drop duplicates.
3. For every post make ONE call to Jev (TypeSafe API, model jev-latest, or experimental_evaluate through the Vercel AI Gateway if that is what I have). The state is the author's name and the post text. Ask together:
- buy: "Is the author of this post personally looking to buy, hire or choose a product, service, vendor or tool for their own business right now? Someone selling, promoting their own offer, giving advice, or posting a job ad does NOT count."
- one question per kind of thing they might want, so you can say what each buyer needs.
4. Run 16 calls at a time and retry on 429 or 5xx. Keep every post that scores 0.80 or higher on buy.
5. Write buyers.csv (score, wants, url), best first, and tell me the search cost and the Jev cost separately.
Stop there. Never comment, message, connect or reply to anyone yourself. I read every post and reach out by hand.Other people built this too
Same idea, pointed at people you already know:
- 18,064 LinkedIn connections, sorted by @rubenhassid. Streams a LinkedIn export through Jev to find the CEOs, COOs and chiefs of staff: keep, review or reject. 18,064 rows for 70¢.
- Ask your network by @chrisbrownridge. Type “people in sales at small companies in New York” and your LinkedIn contacts re-rank live. 300 people in 1.51s for 1.2¢.
- ICP check on a whole network by @robvjourney. Runs every LinkedIn connection through an ICP check and buckets them into warm, maybe, cold and not relevant. 25,033 connections.
More like these in the Jev resources, sorted by team.
The honest part
This was one run, on October 12, 2026. Different searches on a different day will give different posts and a different count.
After scoring, I looked up the public headline of the top 14 buyers through Treg. 12 came back, for 1.5 cents. That step took almost four minutes because Treg kept answering “busy” and the script retried. You don’t need it to find buyers.
Nothing here contacts anyone. It hands you a list. Reply to what they actually asked, follow LinkedIn’s rules, and remember a post asking for help is an invitation to be useful, not to pitch.

The setup guide is one key and a few lines of code, and you’ll have a working response in a few minutes.
