Ideal client: early-stage founders and small GTM teams (often bootstrapped or pre-seed, many of them women founders and technical builders) who can ship a product fast but struggle to get it in front of the right people.The challenge: The founder wrote it on October 31: “My plan is to move from demand validation to adoption in November.” The waitlist hit 297. Now the question changes: of everyone reacting to the posts, how many are founders who could use the product, and which posts bring them?

Who actually reads you, and what the LinkedIn algorithm changed
The founder posted 27 times in two weeks: the countdown to 300 on the waitlist, the relaunch of the product after a pivot, growth experiment advice, trips to New York and Boston, and the people met on the way. One feed, run like an experiment.
The LinkedIn algorithm shows a post to the people who reacted to the last ones, then to people like them. When coaches and investors react the most, the feed keeps reaching more of them. Reach can’t tell whether the founders who could run experiments on the product are in it. Who reacted can. We looked at every person who reacted between 21 October and 3 November, and sorted them by role.

Peers lead: 100 founder coaches, consultants, fractional growth leads, investors and agency owners. Many of them run founder communities and events, so they bring visibility and introductions. Few of them will run growth experiments in the product themselves.
The buyers are there too: 73 founders, CEOs, CTOs and heads of growth, many of them building AI, software and consumer products at the earliest stage. More than 1 reader in 4.

Most founders judge a post by its reactions. A founder selling to other founders should judge it by who reacted.
We tagged each of the 27 posts by topic, then measured the share of founders among the people who reacted, and how many of them each post reached.

For comparison, the relaunch post got 143 reactions, the biggest of the period, and brought 20.6% founders. It reached the most founders in absolute terms (20), but most of its reactions came from peers and friends of the company.
These rules come from what worked on the founder’s own profile in the last two weeks, and from the best-performing posts by startup founders, growth strategists and early-stage investors on LinkedIn since August.
1
Write about the people, not only the product. Founders follow founders. The people met at a conference, the founder who pushes you every week, the person at the next table: that is where readers see who you are, and who you work with.On this profile: the 6 events and people posts brought 29.7% founders and 6.8 founders per post, the product updates 13.6% and 1 per post.
Tell the sale as a scene. A dialogue reads in five seconds and makes the point without a lecture. Founders who fear selling see themselves in it.On this profile: the coffee shop dialogue with a founder coach brought 31% founders, 9 in the 29 read.
Give the experiment its numbers. Say what you tested, for how long, and what moved. A real number turns a growth tip into proof founders can copy.Across the niche: a GTM engineering founder’s post on 22 posts in 7 days, 300k impressions and 109 sign-ups got 234 likes and 653 comments.
Turn your stance into a rule founders can repeat. Strong opinions on testing get shared when they fit in one line. Give the order of steps, and the reason.On this profile: “Before you spend a dollar on ads” brought 33.3% founders. Across the niche: a startup strategist’s “make the idea earn more of your time” got 228 likes with 4.9K followers.
After the launch, show the beta numbers. The launch post gets the reactions. The post a few weeks later, with what users actually did, gets the founders who are deciding whether to try it.On this profile: the relaunch post reached 20 founders, the most of any post. Across the niche: a founder’s “Launched 2 months ago. Private beta. Hitting $7,790/mo.” got 187 likes.
Name the distribution problem founders feel. Building got easy. Getting a person to use what you built did not. Say it in their words, then show the way out.On this profile: the post to dev agencies who “can build anything... but need help with distribution” brought 33.3% founders. Across the niche: an early-stage investor’s “Minimum Visible Distribution” post got 792 likes.
When founders read: the best time to post on LinkedIn for startup growth founders
We compared the share of founders by the day and the hour (New York time) each post was published. Only hours with 3 or more posts are shown. 27 posts in two weeks is a small sample: read the days as a direction, not a rule.

Friday brought the highest share of founders (29.5%, 5 posts) and Monday the most per post (10), with the relaunch. Saturday was the weakest day (8%, 3 posts).
Posts at 16:00 brought 26.3% founders and those at 8:00 23.3%; 14:00 was the weakest slot (12.9%). At around 13 posts a week, fewer, stronger posts on Tuesday and Friday at 8:00 or 16:00 will do more than a post every few hours.

5 posts ready to publish to target founders
Each post follows the rules above, in the founder’s voice. Swap in your own details before posting: the real conversations and the real numbers are what make them land.

What 85 women founders and investors taught me in one dayRule 1: the people, not the product. Modelled on the Jess Lynch post (31% founders, 18 in the 58 read).
Hook
I walked into a room of 85 women founders and investors with a beta and walked out with a to-do list.UpLevel was the first time I showed the new Theanna to people who didn’t already know me from here. And they did NOT go easy on me (thank god).3 things I can’t stop thinking about:1. Nobody asked about features. Every founder asked “what would you test first, for MY company?”2. The founders who were furthest along weren’t the ones with the biggest teams. They were the ones who could tell me the one number they were trying to move this month.3. Asks and offers before you walk in changes everything. I had more real conversations in one lunch than in most full conferences.I went to share what we’re building. I came home with better questions than answers.Thank you Jess Lynch for building a room like that. I’m still buzzing 💜If you were there: what’s the one thing you’re testing this month?

“So what would you test first?”Rule 2: the sale told as a scene. Modelled on the coffee shop dialogue (31% founders).
Hook
her: "ok but what would you test first?"me: "what’s the one number you want to move this month?"her: "booked calls. I have 3 a week, I want 10"me: "where do your 3 come from?"her: "honestly... LinkedIn DMs I send when I remember to"me: "cool. for 14 days you send 5 a day to people who reacted to your posts. same message. you track every reply. that’s your experiment"her: "that’s it?"me: "that’s it. one number, one clock, a real person on the other end"She signed up on the spot.This is the thing nobody tells you about selling as a founder. You don’t pitch the product. You solve one tiny piece of their problem out loud, and the product is just the place where it happens.Stop hiding behind the demo video. Get out there and solve something in the hallway.What’s your one number this month?

I ran 10 experiments in 31 days. Here’s what moved.Rule 3: the experiment with its numbers. Modelled on Tim Scheuer’s 22-posts-in-7-days post, built from the waitlist countdown posts.
Hook
Goal: 100 people on the waitlist. Result: 297. Here’s what actually moved it.On October 1 I set out to validate the demand for Theanna’s pivot. 100 people would make me feel ok about it. I hit 100 on October 10, so I tripled the goal.I tracked every signup by channel. What I learned:→ Email and social posts brought most of the signups. The profile link brought the least.
→ Posting every day felt like too much. It wasn’t. Every post was a new chance for someone to see it for the first time.
→ The posts that worked best weren’t the product posts. They were the ones with a number and a deadline (“6 days left, can I make it to 300?”).
→ Saying the goal out loud did half the work. People wanted to help me hit it.The real goal was never a number. It was to find out if people want this.They do. Now the next experiment: going from waitlist to adoption.What number are you trying to move this month?

Drop your startup, I’ll reply with your first experimentThe lead magnet: a personal 7-day experiment for every founder who comments. Modelled on Vahid Fakhr’s “drop your startup” post (656 comments).
Hook
Drop your startup below and I’ll reply with the one experiment I’d run this week.Not a strategy deck. Not a 40-tab plan. One experiment.Here’s what I need from you, in one line:→ what you sell, in a sentence
→ who buys it
→ the one number you want to move (followers, visitors, signups, calls booked)And I’ll reply with:→ the experiment
→ the clock (7 to 14 days)
→ how you’ll know if it workedI’ve watched founders on the Theanna experiment board this month do exactly this. One city, one channel, 14 days. Small bets, measured honestly.I’ll answer every comment through Sunday night. GO 👇

Building is easy now. Distribution isn’t.Rules 4 and 6: a stance founders can repeat, and the distribution problem in their words. Modelled on “Before you spend a dollar on ads” (33.3% founders).
Hook
You don’t have a product problem. You have a nobody-has-seen-it problem.You can ship a product in a weekend now. MCPs, agents, automations. Amazing.But the founders I talk to every week are stuck in the same place: the thing works, and nobody knows it exists.The fix isn’t more features. And it isn’t ads (I WILL STILL DIE ON THIS HILL).The cheaper order:1. Pick one channel where your buyers already hang out
2. Post or reach out there every day for 7 days
3. Track real visits and replies, not likes
4. Keep the message that got clicks, kill the rest
5. Only then put money behind itBuilding got fast. Distribution is still a game of reps. The founders who win are the ones running the most reps.Where does your next 10 users come from? Tell me the channel 👇

LinkedIn lead generation: lead magnets that work to target founders
Reactions show interest. A comment asking for something shows intent. The quickest way to find out which founders are serious is to give them something useful and see who asks for it.
Among startup founders, growth strategists and early-stage advisors, these formats get the most requests:
Format 1The personal answer in the commentsAsk founders to drop their startup in one line and answer each one yourself. Every comment is a founder raising a hand.
Format 2The tool you built for yourselfThe tracker or system that runs your own work, given away as it is. Proof of the method, and useful the same day.
Format 3The template that took hoursSay how long it took and what it would cost, then give it for a keyword. Founders trade a comment for a shortcut.
Format 4The growth mapEvery channel and the order to run them, on one page. It answers “where do I start?”, the question every early-stage founder asks.
Our pick for you: “Your first experiment, written for you”Built from the founder’s experiment board (one number, a clock, a real person on the other end): founders drop their startup and the number they want to move, and get one 7-day experiment back in the comments. It shows the product’s value before the sign-up. Offer it in post 4, on a Friday at 16:00.With a Reveal link, every person who downloads it is shown by name, with their role and how warm they are.

From reactions to clients
Content brings founders to the profile. It doesn’t say when to reach out. Most never comment, so they stay invisible, and a founder reading every post during launch week may have picked another tool by December.
On LinkedIn, the right moment to start a conversation is when someone keeps coming back. We call that Hot: 5 or more points over 90 days, where a reaction counts 1, a repost 2, a download or a reply 4.

For this founder, Friday brought the highest share of founders (29.5%) and Monday the most per post, with the relaunch. Saturday was the weakest (8%). With 27 posts in two weeks, what the post is about matters more than the day.
This founder posted about 13 times a week during a launch, and 10 founders came back 3 times or more in two weeks. Daily posting works for a countdown; after it, fewer and stronger posts on the best days keep the founders reading.
Look at who reacts, not how many. The biggest post here (143 reactions) brought 20.6% founders, a 12-reaction post on testing channels before ads brought 33.3%. Group reactions by role and follow the people who keep coming back. A free Netwarm scan does this for you.
Yes. Netwarm only reads public reactions to your own posts. It never logs in as you, never asks for your password, and never messages anyone for you.
How we made this playbook
We read the public reactions on 27 posts published between 21 October and 3 November 2026, up to the first 100 people per post (474 of the 535 reactions), and sorted the 263 people by role. Comments were not counted, so engagement figures are a floor. One deleted post and two posts about the creator written by someone else were left out.
Niche rules come from top posts by startup founders, growth strategists and early-stage investors since August. Role groups are approximate; some founders also coach or invest. A Netwarm scan matches people to your own ideal client.
