The LinkedIn company milestone post signal
Last updated 23 October 2026
You can use the LinkedIn company milestone post signal to start outreach with HeyLead. This page explains what the signal means, how it is detected, and how to write a message that gets a reply.
What the company milestone post signal is
The company milestone post signal means a company posted a revenue, customer or growth milestone. 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.
The signal comes from a company's page or hiring on LinkedIn. HeyLead reads the company's LinkedIn page. It looks at its posts, the reactions and comments on them, and its followers.
Why this signal matters for outreach
HeyLead watches 40+ signal types, scored, matched to your ICP and expiring. A strong signal starts outreach and the opener says why now. The company milestone post signal has a weight of 0.35.
Scores run from -0.30 to 0.90. A negative score lowers priority. This signal expires after 14 days. It is attached to a company. HeyLead attaches it to campaign contacts at that company. It raises priority but does not write the invite note.
What to write when a company hits a milestone
You must write to a person at the company, never to the company. Name the company event in the first line. Ask how it changes the person's own work. HeyLead reads your own LinkedIn posts to learn your voice and never posts unless you ask for a post.
Before an invitation, HeyLead warms up: a profile view, a follow, a comment on a recent post. It sends an invitation with a note, an opening message, up to 2 follow-ups on Free and 5 on Pro, InMail and email fallback.
The brief to type into HeyLead
You type a one-sentence brief in Claude, Cursor, ChatGPT or the HeyLead dashboard. HeyLead drafts the campaign. You review it and press Launch. Nothing is sent before. One sentence creates a draft campaign. Nothing is sent until you press Launch.
Six 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.
It works in Claude Code, Cursor, Claude Desktop and claude.ai, any MCP client and a web dashboard. It works in ChatGPT as a custom MCP app. This is tested on ChatGPT Pro. Custom apps depend on your ChatGPT plan and settings.
How HeyLead handles replies and limits
Replies are read, classified and answered from the campaign's facts. Anything ambiguous is held for you. A "not now" gets a check-in in 30 days. 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 runs from the cloud with your laptop closed. Free costs $0 for one 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. HubSpot is the CRM it syncs with. Google Calendar is the calendar it books into.
