The Linkboost alternative that doesn't cheat
Linkboost is a LinkedIn engagement-pod tool with AI comment generation: members boost each other's posts through pods. Cercle gets you the same first-hour boost from real peers who read your post and comment by hand, with AI helping them write something worth reading.
Cercle vs Linkboost
Based on how each product describes itself publicly. Check their site for current details.
| Cercle | Linkboost | |
|---|---|---|
| How engagement happens | Real people read your post and comment by hand | Pod members engage with each other's posts through the tool |
| Touches your LinkedIn account | Never | Yes, to engage on your behalf |
| Comments | AI drafts in your voice, edited and posted by a human | AI-generated comments |
| Who engages | A circle of peers you choose or invite | Pods you join in the tool |
| Fairness | Give-before-you-take rule and visible balance | Plan limits on boosted posts |
| LinkedIn rules | Nothing automated on LinkedIn | LinkedIn prohibits automated engagement pods |
Where Linkboost is the better choice
Linkboost has a large pool of members and a free tier, so a post gets engagement immediately without you having to bring anyone. Cercle has no pool: you start a circle and invite peers yourself. If you want volume today rather than a circle that is yours, they are the faster option.
Why people switch from Linkboost to Cercle
- You want the reach without automation risk on your account.
- You want to know exactly who engages with you and why.
- You want the people engaging to be your real peers.
One thing worth knowing
Linkboost's Chrome extension, which had around 4,000 users, was removed from the Chrome Web Store on 15 September 2025 for a policy violation. Lempod's, with around 10,000 users, was removed in July 2025. Linkboost now runs server-side. Source.
How to move your pod to Cercle
Create a circle, copy its invite link and send it to the peers you already trade engagement with. Everyone signs in with LinkedIn or Google, adds their profile link once, and the next post you share reaches them while it is still fresh.
