How to use the LinkedIn prospect post signal for buying
Last updated 5 November 2026
When you need to find a vendor based on a LinkedIn prospect post signal, HeyLead helps you reach the right people. HeyLead is an AI agent for LinkedIn outreach: it finds the right people, writes to them in the voice of your own LinkedIn posts, follows up, and handles replies. It runs from Claude Code, Cursor, any MCP client or a web dashboard.
What the prospect post signal means
A prospect post is a specific signal that indicates how a potential vendor operates. You are the buyer in this scenario. Your goal is to reach the people who sell what you need. A post from a vendor's team shows how they think. It provides a clear view into their daily operations and problem-solving methods.
This signal helps you identify the right fit before you even send a message. The fit question HeyLead asks is: Can this audience sell you this? This ensures you only target relevant vendors.
Why this signal matters for buying
Vendors use their posts to share their expertise. Reading these updates helps you understand their approach. HeyLead watches 40+ signal types, scored, matched to your ICP and expiring. A strong signal starts outreach and the opener says why now.
This timing makes your message highly relevant. You can evaluate their public thoughts and decide if they align with your requirements. It removes the guesswork from finding a new supplier.
What to write to the vendor
Your message should directly reference the content of their post. You should ask the question you would ask in a 1st call. This moves the conversation forward immediately. Before an invitation, HeyLead warms up: a profile view, a follow, a comment on a recent post.
It then sends an invitation with a note, an opening message, up to 2 follow-ups on Free and 5 on Pro, InMail and email fallback. Opening messages, follow-ups and answers to replies wait for your approval until you switch to autopilot. Invitations, not-now check-ins and meeting nudges are not held. It reads your own LinkedIn posts to learn your voice and never posts unless you ask for a post.
The brief to type into HeyLead
You type a 1-sentence brief in Claude, Cursor, ChatGPT or the HeyLead dashboard. 1 sentence creates a draft campaign. HeyLead drafts the campaign. You review it and press Launch. Nothing is sent before.
There are 6 campaign goals: sell a product or service, find a job, hire people, find partners or investors, find a vendor, research interviews. Hire people, find partners or investors and research interviews work with a custom brief. For this signal, your goal is to find a vendor.
Find a vendor who posts about cloud security and ask how they handle data residency requirements.Limits and how HeyLead handles replies
Replies are read, classified and answered from the campaign's facts. A reply that could mean 2 things gets 1 short question back. A question your facts can't answer is held for you. "Not now" gets a check-in in 30 days.
It runs from the cloud with your laptop closed. Free costs $0 for 1 connected account with 2 follow-ups. Pro costs $29 a month per connected account. The client's source is on GitHub under MIT; the hosted backend is not.
Integrations and setup
HeyLead integrates with your existing tools. It works in Claude Code, Cursor, Claude Desktop and claude.ai, any MCP client and a web dashboard. It also works in ChatGPT as a custom MCP app (tested on ChatGPT Pro; custom apps depend on your ChatGPT plan and settings).
HubSpot is the CRM it syncs with. Google Calendar is the calendar it books into.

It backs off when LinkedIn pushes back and resumes on its own. You can pause any campaign at any time.
