LinkedIn Comment to DM for SaaS Founders: Turn Comments into Trials and Demos
Ruz, Founder LeadShark · Updated Oct 26, 2026 · 6 min read
SaaS founders turn LinkedIn comments into trials and demos by posting something useful, asking for one keyword, and letting a comment to DM tool like LeadShark send every commenter the link. The first DM delivers the resource, and a follow-up filtered to your ideal customer offers the trial or demo.
In short:
- Lead with value, not the product. A template, teardown or calculator gets comments; "book a demo" rarely does.
- Deliver first, pitch second. The DM sends the resource; the follow-up offers the trial.
- Filter for fit. Follow-ups can go only to commenters whose headline matches your ideal customer.
- Pipe it into your stack with webhooks, CSV or Google Sheets.
Why comment to DM fits founder-led sales
Founder-led sales runs on posts people actually comment on. Every comment is a named person with a headline, raising a hand on a topic you picked. A DM a few minutes later, in under 10 minutes on average with LeadShark, reaches them while they still care. Doing that by hand on a post that takes off means an evening in your inbox instead of building.
6 founder flows
| Goal | What the post offers | Keyword | What the DM sends |
|---|---|---|---|
| Free trials | A template or checklist your product makes easier | TEMPLATE | The resource, then a follow-up with the trial link |
| Demos | A short walkthrough or teardown | DEMO | The walkthrough, then a follow-up with your booking link |
| Waitlist | A preview of what you're building | WAITLIST | The waitlist link on an email-gated page |
| Beta invites | Early access for a few users | BETA | The beta signup link and one qualifying question |
| Launch day | The launch post with a perk | LAUNCH | The launch link and the perk |
| Content to pipeline | A calculator or benchmark sheet | SHEET | The sheet, then a follow-up for the people who fit |
How to set it up
- Post something useful for your buyer and end with one keyword. Ideas: 8 comment GUIDE post templates.
- Automate the post in LeadShark. Pick it (live, scheduled or your next one), set the keyword and write the reply and DM. Picking the word: how to pick and set keyword triggers.
- Deliver first. The DM sends what you promised and ends with one question. Click tracking shows who opened it.
- Follow up with the offer. A follow-up DM only goes to people who didn't reply, and you can filter it to commenters who fit your ideal customer.
- Send leads to your CRM with webhooks for new comments, captured emails and sent leads, or export to CSV or Google Sheets.
Commenters who aren't connections get a connection request, and the DM goes out once they accept. On Apex, LeadShark can also DM commenters you aren't connected with.
Copy you can paste
Demo. The post ends with:
I recorded a short walkthrough of how we [solve problem] for [type of company]. Comment DEMO and I'll send it.
The DM:
Hey {{firstName}}, here's the walkthrough: [link]
What are you using for this today?
The follow-up, filtered to your ideal customer:
{{firstName}}, if it's useful, I can show you this on your own setup. Here's my calendar: [link]
Free trial. The post ends with "Comment TEMPLATE and I'll send you the template we use." The DM:
Hey {{firstName}}, here's the template: [link]
It's built for [product], and there's a free trial if you want it to fill itself in: [trial link]
Beta. The post ends with "We're opening the beta to a few teams. Comment BETA and I'll DM you the details." The DM:
Hey {{firstName}}, here are the beta details: [link]
Quick one: how big is your team?
Every reply and DM is a template you write, and only details like the first name are filled in. LeadShark doesn't generate replies with AI.
Where the leads go
| Destination | What you get |
|---|---|
| Your CRM | Webhooks for new comments, captured emails and sent leads |
| A spreadsheet | CSV or Google Sheets export |
| Your newsletter | Kit or Beehiiv sync from an email-gated page (1 on Pro, 100 on Pro+, unlimited on Apex) |
| Your own code | The LeadShark REST API for posts, comments, invitations, webhooks and scheduling |
| Claude or ChatGPT | The LinkedIn MCP server on Pro+ and Apex, so your agent can set up automations and pull leads |
Personal profile or Company Page?
Post from your personal profile: founder posts are where the comments are, and the DMs go out from your profile. On Pro+ and Apex you can also run an automation on a Company Page post, with the DMs still going out from your personal profile, and Apex can auto-reply in the comments as the page.
What not to do
- Don't pitch in the first DM. Deliver what they asked for.
- Don't send cold sequences. LeadShark only messages people who commented on your post.
- Don't follow up more than you'd do by hand. One well-timed follow-up beats a sequence.
- Don't fire every DM at once. Set 0 to 250 DMs a day (150 recommended max) and let pacing spread them out. More in is LinkedIn comment to DM automation safe?.
