> **The idea, in one sentence.** When you launch a **SaaS**, you have no ad budget, no audience, and no time to waste. The **LinkedIn comment** is your best starting channel: without posting, it puts you **in front of your early adopters, design partners, future talent and investors** — exactly the people founder-led marketing aims at. This guide lays out the tactics **specific to the founder**: who to comment under, what to write, and where it leads. Backed by our first-party LinkHub data; third-party numbers are dated and flagged, none invented. ⚠️ The comment builds familiarity and pipeline, not the signature or the funding round.

## Key takeaways

- **For a founder, the comment beats the post at the start.** With no audience, your post falls flat; a comment borrows a niche creator's audience and makes you visible **today**. *(see [grow without posting](/en/blog/grossir-linkedin-sans-poster))*
- **Your comment ICP isn't a single audience.** You want to reach **four circles** at once: early adopters, design partners, talent and investors — each gathers under different hosts. *(see [comment ICP](/en/blog/icp-commentaire-linkedin))*
- **The right host changes everything.** Across 4,861 creators, commenting on a top 10% earns **~3.4x more** impressions than the median (124 vs 36), a top 1% **~10x** (357). *(LinkHub)*
- **Timing multiplies the effect.** Commenting in the **0-30 min** window earns **~3.8x** more than after 24h. *(LinkHub, 261,137 comments)*
- **Founder-led, not brand-led.** Early-stage buyers follow **founders**, not logos. Your face and voice carry further than your company page.
- **The goal is the conversation.** Each comment aims at a profile visit, then a warm DM: a product discovery call, a design-partner coffee, a hiring chat or an investor exchange.

## 1. Why the comment is the founder's best early-stage channel

At launch, you face three simultaneous shortages: **no ad budget**, **no audience**, **no time**. Ads cost a CAC you can't yet afford. Posting does almost nothing while nobody follows you: the algorithm shows your post to a handful of contacts, and if it doesn't engage, it dies *(detail in [grow without posting](/en/blog/grossir-linkedin-sans-poster))*.

The comment bypasses all three shortages at once. When you comment on a post by a creator **your market already follows**, you appear in front of their audience — without having built it, without paying, in a few seconds. That's the very definition of **founder-led marketing** applied to the most accessible channel: your founder voice, where your future customers already read.

And the terrain works for you: reach has concentrated on strong creators — "Top Creators" visibility went from 15% (2022) to 31% (2025) per [van der Blom](https://www.linkedin.com/posts/richardvanderblom_chapter-1-algorithm-insights-report-2025-activity-7322514599126130688-Q895). In other words, the audience gathers under a small number of hosts: you just need to identify **the right ones** in your niche and post yourself there in comment.

## 2. Your four comment ICPs: early adopters, design partners, talent, investors

A founder doesn't just sell a product — they recruit users, co-builders, employees and funders. The comment reaches all of them, provided you think in **comment ICP**: not "who I talk to," but **which creators to comment under to land in front of them** *(full definition in [comment ICP](/en/blog/icp-commentaire-linkedin))*. Your four circles don't read the same hosts:

- **Early adopters** — they follow creators who talk about the **problem** you solve (not your product category). Comment under those who describe your future customers' pain.
- **Design partners** — highly engaged practitioners, often power users of competing or adjacent tools. They hang out under your niche's technical posts.
- **Talent** — the builders you want to hire follow "craft" creators (engineering, design, growth). Commenting thoughtfully under them makes you desirable as an employer.
- **Investors** — VCs and angels post and comment on LinkedIn. Showing up regularly, with a relevant angle, under posts in your thesis puts you on their radar **before** any cold email.

Raw reach isn't enough: you need the **right** reach. A niche creator followed by your early adopters beats a generalist account with 100,000 off-topic followers. To identify these hosts without guessing, LinkHub's **[AI profile recommendation](/en/features/ia-recommandation-profils)** infers your ICP from your profile, then searches **100,000+ LinkedIn profiles** for the best ROI for your niche.

## 3. What to write: the founder comment that builds credibility

A founder has an unfair advantage in comments: **you live the problem from the inside**. Your comment should never read like an ad for your SaaS — it should prove, in passing, that you know the subject better than anyone. Aim for **15-40 words**, add data, a field insight or a reasoned disagreement *(draw from these [comment examples](/en/blog/exemples-commentaires-linkedin) and the [write a good comment](/en/blog/ecrire-bon-commentaire-linkedin) method)*.

Concrete example, under a growth creator's post saying "SaaS onboarding must be self-serve":

> True, but we saw the opposite in our early access: our first 20 accounts activated **2x faster** with hands-on human onboarding. We only tooled the self-serve flow once we'd pinned down the "aha moment" on the phone. What usage threshold do you watch before switching?

This comment does four things at once: it **adds field data**, it **positions you as a founder who builds** (product credibility + talent), it **opens a discussion** (the creator and their audience reply), and it **didn't pitch**. That's exactly what turns an impression into a profile visit — where your headline and "About" section take over.

## 4. How to find the right posts and comment at the right time

Two reflexes multiply the effect: being **early** and targeting the **right host**.

**The right host.** At equal effort, across **4,861 creators**, commenting on the median earns 36 impressions, a top 10% **124 (~3.4x)**, a top 1% **357 (~10x)** *(see [who to comment on](/en/blog/sur-qui-commenter-linkedin))*. Same comment, under the right creator, seen 3 to 10x more — provided its audience contains your four circles.

**The right time.** Across 261,137 real comments, a comment posted in the **first 30 minutes** generates **391 impressions on average**, versus **104 after 24h** — about **~3.8x** ([van der Blom](https://www.linkedin.com/posts/richardvanderblom_chapter-1-algorithm-insights-report-2025-activity-7322514599126130688-Q895) confirms the first hour captures most of the reach; see [when to comment](/en/blog/quand-commenter-sur-linkedin)). A post gets its reach peak in its first hour; commenting then exposes you to the maximum audience.

The practical problem — a founder has no time to watch the native feed — is solved by **[personalized feeds](/en/features/feeds-personnalises)**: you group your hosts (one feed per circle if you want) and see their posts **as soon as they go live**. Combined with **[AI-personalized comments](/en/features/ia-commentaires-personnalises)** (always validated by you), a comment takes **~29s measured** (median, n = 44,523) — doable even mid product sprint. The spotting method is detailed in [finding the right posts to comment on](/en/blog/trouver-bons-posts-commenter-linkedin).

## 5. From comment to design partner (and the rest)

The impression is only a means. The founder's goal is the **conversation**: LinkedIn is a social network, and your job at the start is to talk to humans, not stack views *(the full path [from comment to client](/en/blog/commentaire-au-client-linkedin))*. The typical journey:

1. **Comment** under the host your circles follow — you exist for them, several times.
2. **Exchange in replies** under the post — a first public link, no pitch.
3. **Move to a warm DM** referencing the exchange ("we chatted under X's post") — you're no longer a stranger.
4. **Convert by circle**: a product discovery call with an early adopter, a design-partner coffee, a hiring chat with a builder, a deeper exchange with an investor.

That's the logic of the [comment acquisition funnel](/en/blog/trouver-clients-linkedin-commentaires), applied to a founder's four missions. And it compounds: by repeatedly exchanging under the same hosts, you become **familiar to your whole niche** — the network effect that will later make your own posts (when you make them) far more visible.

## 6. Should you comment before the product is ready?

Yes — it's even the best time. Commenting **before** launch builds an asset ads can't buy: familiarity with your market and a warm list of early adopters and design partners ready to test. You don't wait for a finished product to talk; you talk about the **problem**, and you recruit the people who live it.

Be honest about what this produces: our data measures **impressions and familiarity with your ICP** — not a count of signups, deals or rounds raised. The link between "being seen by the right circles" and "finding your first 10 customers or your design partner" is **reasoning backed by the mechanism**, not a first-party measurement. ⚠️ Correlation isn't causation: the comment creates the ground; it's on you to convert the conversation.

## FAQ

**Should a SaaS founder comment or post first?**
Comment first. With no audience, your posts will be barely seen; the comment makes you visible today in front of your early adopters, design partners, talent and investors. You can post later, once a first network is built — and commenting will then boost your posts.

**How do I find my early adopters and design partners through comments?**
By commenting under the creators who talk about the **problem** you solve (not your product category). Their audience contains the people who live that pain. Target these hosts via the [comment ICP](/en/blog/icp-commentaire-linkedin) and the [AI profile recommendation](/en/features/ia-recommandation-profils).

**Can comments really attract investors?**
It puts you on their radar before any cold email: VCs and angels post and comment on LinkedIn, and showing up regularly, with a relevant angle, under posts in your thesis builds familiarity. It doesn't "open" a round on its own — it sets up the conversation. What our data measures is visibility, not raises.

**How much time should a founder spend on it?**
A few minutes a day. With LinkHub, a comment takes ~29s measured (n = 44,523); 5 to 10 targeted comments fit in a coffee break, even mid product sprint. Consistency beats intensity.

**Should you comment before having a finished product?**
Yes. Commenting before launch builds familiarity with your market and a warm list of early adopters — an asset ads can't buy. Talk about the problem, not the not-yet-ready product.

## Sources & methodology

- **First-party LinkHub data** — impressions per comment (657,722 comments), creators commented on (`creator_stats_cache`, 4,861 creators: p50 = 36, p90 = 124, p99 = 357), timing (261,137 comments), measured creation time (n = 44,523). The number of signups, deals or rounds raised is **not** measured: the funnel mechanism is reasoning backed by these signals + third-party studies.
