I became a founder to build cool things.
Not to become a content creator who builds cool things on the side.

But here's the problem: If you don't post on LinkedIn, you don't exist. You don't get leads. You don't get users. You don't get noticed.

So I tried everything ⤵︎
→ Opening a Google Doc and chewing on my pen with a blank mind 
→ Used templates (too cringe, felt like everyone else).
→ Tried vanilla AI (we already have too much crap like this on our timelines)

I ended up spending hours every week staring at a blank cursor, or posting things that felt like a chore.

So I built Ziplined.

I wanted a way to just talk to my AI, the one I'm already using for code and strategy (Claude or ChatGPT)  and have it write content that actually sounds like me, based on data that actually works.

No new apps to open.
No app to forget about after 2 days
No becoming a LinkedIn influencer.

Just "Hey Claude (or ChatGPT), write a post about X" and getting a result I'm actually proud to publish.

It changed my workflow completely. I timed it, spend around 12 minutes on an insanely good post now.

That's what Ziplined does:
→ Works directly in ChatGPT or Claude (no new tool to learn)
→ Auto-syncs your LinkedIn analytics (knows what works for YOUR audience)
→ Connects to your docs and history (knows your ICP, voice, strategy)
→ Searches 10,000+ proven founder posts (not guru templates, actual results)

The result?
Posts that sound like you, get clients, and take 12 minutes instead of 2 hours.

More importantly: It doesn't feel like a chore anymore. I actually enjoy posting now.

Which means I actually do it more and can keep doing it (even more important)

If you want to build in public without the burnout, I think you'll love it.

Launching February 9, 2026.

I just realized why founders are so weird.

It's Friday 7pm and I'm still yelling at my code...

Normal people on Friday night:
→ Getting beers with colleagues
→ "What are your weekend plans?" conversations
→ Already planning Saturday brunch
→ Phone on Do Not Disturb

Founders on Friday night:
→ "WHY THE DUCK IS THIS STILL NOT WORKING"
→ Answering customer emails at 11:47pm
→ Having random ideas that need to ship in 30 minutes
→ Opening Cursor for "just a quick fix" (3 hours ago)

Nobody forced us into this.

We saw normal Friday nights and said "nah, I'd rather debug API endpoints while everyone else is at the pub."

We chose it.

And I salute you 🫡

Ziplined.io IS LIVE NOW! | For Founders who post on LinkedIn, you’ll want to see this.

Ziplined's been live for 7 days.

The 4th Sunday update ⤵︎

Update of the numbers:
→ Waitlists: 239
→ Paying users: 60 (can open 3 bottles already 😎)
→ Cancellations: 3
→ Conversion: 25% (only 2 emails sent, so more to come!)

Insights:
The feedback has been incredible.

People are publishing their first posts. Planning consistent content. Actually using it.

That's the part that feels freaking awesome.

The 3 cancellations; All ChatGPT users with the same complaint: "Still sounds a little too AI, not enough like me."

So my focus is on fixing this ASAP.

My game plan: creating the Ziplined Writing Engine that ChatGPT can talk to. 

A step closer to solving the pain for customers.

What shipped this week:
→ Image uploads (you can now add visuals to posts, not just text)
→ Better scheduling system (managing and rescheduling saved posts actually works now)
→ Improved brandvoice analysis (way more thorough and accurate at capturing your tone)
→ 8 customer calls (real feedback from actual users = gold)
→ 15 bug fixes (turns out launch week reveals a shitton of issues)

Focus for next week:
→ Ship the new writing system. 
→ Fix the AI voice problem in ChatGPT
→ Keep talking to users.

That's it.

Next update upcoming sunday!

PS:
☑️ 1th user bottle 
☑️ 10th usersbottle 
☑️ 50th user bottle
⬜ 100th user bottle

Ziplined has 61 paying customers.

Here's my 5-point game plan to hit 150 by March 31:

1. Obsess over current customers

Implement all most requests and fix all bugs, as fast as possible.

Then email every single one of them: do you know a founder who'd genuinely benefit from this?

61 happy customers is 61+ potential referrals. If that doesn't work, I'm adding an affiliate incentive. But I want to find out if people refer just because they love the product first.

2. Convert the waitlist

248 people signed up because they have a LinkedIn problem. That's not a cold list, that's a warm one.

I'm emailing all of them to figure out exactly what's stopping them from converting. My gut says 40-50% should convert because they opted in for exactly this reason.

→ What did they see? What wasn't clear? What made them hesitate?
→ Anyone who starts onboarding but drops before checkout gets a follow-up email
→ Every answer shapes the next email

3. Free tools that prove the product

One free tool a week. Based on the exact pain points I hear from founders.

→ Week 1: Custom GPT that generates LinkedIn content ideas based on your profile
→ Then follow up, learn what's still broken, build the next one

The logic: fix one real problem for free, and the paid product sells itself.

4. Weekly founder breakdowns

Every week I pick a founder killing it on LinkedIn and do a full breakdown. Their hooks, post strategy, profile, consistency. What's working and why. How you can copy it.

Starting with:

→ Alex Lieberman, cofounder of Morning Brew (scaled to 4M subscribers, sold for $75M)
→ Adam Robinson, CEO of RB2B (bootstrapped to $10M ARR, one of the most consistent LinkedIn presences in SaaS)

Sharing in the Ziplined newsletter and on LinkedIn.

5. Targeted outbound

10 founders a day. Every day.

When I spot a founder on LinkedIn who's clearly using AI for content but the output is generic and flat, I reach out personally.

10 a day from Feb 19 to March 31 is 400 outbound messages. 🫡

150 by March 31. Will keep you up to date!

I tracked my ACTUAL LinkedIn ROI last month.

The numbers got out of hand fast ⤵︎

71,511 organic views. 26 posts. Zero ad spend.

Here's what that's actually worth:

🚨 What you can measure: "Media value" vs time invested

71,511 views at $30 CPM: $2,145 you didn't have to spend on ads.

Time invested: 15 min per post max (using Ziplined) × 26 posts = 6.5 hours.

At €100/hr: €650 in → €2,145 out. ROAS: 3.3x
At €150/hr: €975 in → €2,145 out. ROAS: 2.2x
At €250/hr: €1,625 in → €2,145 out. ROAS: 1.3x

Positive at every rate. Before anything else.

🚨 What you can almost measure: Sales

That $2,145 doesn't include a single deal/sale.

Ziplined has been live for 12 days.

I've generated around €5,000 in revenue.

Entirely from founders who found me through consistent posting.

€975 (at $150/hr) in → €5,000 out. ROAS: 5.1x

Combined return (media value + revenue): €7,145 on 6.5 hours of work.

🚨 What you'll never measure: everything else

→ Candidates applying because they followed you for months
→ Deals closing faster because trust existed before the first call
→ Your team seeing outside momentum and pushing harder
→ Investors watching you build before you ever need them

No spreadsheet captures any of that.

6.5 hours of posting this month.

The highest ROI marketing channel most founders completely ignore 🫡

PS: Please send this to your founder friends who are sleeping on LinkedIn ♻️

Ziplined launched 4 days ago.

The most requested feature just went live ⤵︎

Image uploads.

10+ people asked for it in the first 72 hours.

Text is important. But the visual captures attention first.

So I shipped it.

What you can do now:
→ Upload images to your posts
→ Organize them in your content queue  
→ Preview how your post looks on LinkedIn (desktop + mobile)

I'm talking to 3-4 customers daily.

They're shaping the roadmap as we go.

Next up: 
→ Custom Ziplined writing engine for ChatGPT
→ Publishing straight to LinkedIn from Ziplined.

Shipping like a madmen here 🫡

Ziplined.io IS LIVE NOW! | If you post on LinkedIn, you’ll want to see this.

My girlfriend is a little mad at me.

I chose customer calls over cocktails in Strasbourg.

We're here for our 4-year anniversary.

And I'm sitting in our Airbnb doing customer calls.

She still likes me (I checked).

But I get a rush when someone fills in a feedback form, sends me a feature request or does a feedback call with me. I literally can't get them out of my head. 

It's an actual dopamine hit (not the TikTok kind)

For example, yesterday someone asked: 
"Can you analyze engagement on my LinkedIn posts to see if it's actually my ICP talking to me?"

Holy sh*t. That's genius.

Another person: 
"Your 9-step onboarding takes is a little long."

Damn. They're right.

It's exactly the kind of feedback I like. That's why I built a one-click feedback button in Ziplined, to make it as easy as possible to get those dopamine hits.

I get notification emails constantly.
I'm thinking about these ideas 24/7.

Even on a 4-year anniversary weekend in Strasbourg.

I can't turn it off.

And I don't want to.

Because every feature request is someone saying "I want to use your product, but in THIS way."

That's not a complaint. That's a roadmap. 

So my girlfriend is still little mad, but at least my customer aren't 🫡

My Sunday update is now a Tuesday update.

A recap anyway ⤵︎

Numbers:
→ Total paying: 66
→ Waitlist: 254
→ Customer calls this week: 11 😎

What happened last week:
Honestly, not much. Was away Sunday through Wednesday, and Thursday and Friday were not planned for Ziplined either.

So last week was basically a planned write-off.

What did ship:
→ Writing engine for ChatGPT is almost done. Running final tests today. This fixes the AI voice problem I sometimes hear from ChatGPT users: "still sounds too AI, not enough like me."

This week is a recoop week:
→ 3 customer calls done this morning
→ Emailing the waitlist (254 people who opted in because they have a LinkedIn problem)
→ First founder breakdown: Alex Lieberman, cofounder of Morning Brew (4M subscribers, sold for $75M)
→ Shipping free tool #1: a custom GPT that generates LinkedIn content ideas from your profile
→ Shipping simpler better onboarding

Main aim: is 150 by March 31.

Properly locked in from today. More next Sunday. For real this time 🫡

"LinkedIn is just humble brags and thought leaders."

Sure. It's also where all the deals get done.

r/LinkedInLunatics has 670,000 members ⤵︎

"I was sitting in first class when the flight attendant taught me the TRUE meaning of leadership..."
"Unpopular opinion: Hard work works. Agree? 🚀"

The cringe is real.

But staying invisible has a price tag.

One posting streak back in 2024 landed me a contract to build a content engine for a large ecom company. They found me through my posts.

Every euro of Ziplined revenue traces back to LinkedIn.

I've talked to 50+ founders about LinkedIn; same pattern every time:
→ They know LinkedIn works
→ They've seen competitors win deals through it
→ They haven't posted in 3 weeks

The cringe posts aren't cringe because someone posted. They're cringe because you can smell the performance from a mile away.

Write like you'd explain it to a founder friend over coffee.

Less competition for the rest of us 🫡

Want to get humbled real quick?

Talk to your first beta users.

I launched Ziplined on Monday. I've been building & testing it myself for weeks.

Thought I had it the core features down quite well. 

But reality slapped me in the face with real users showing up.

📞 Monday morning, first call:
"I don't have many LinkedIn posts yet. Can I build my brandvoice from my Medium articles instead?"

🤔 Holy shit... That would be very cool actually!

📞 Tuesday:
"I manage 5 clients. Can I set up separate brandvoice profiles for each?"

🤔 Damn. That makes a lot of sense for a Ghostwriter.

📞 Wednesday:
"Can I use my published book as the brandvoice source?"

🤔 wow you have a book? Yeah totally get you want to use that!

In 3 days I got:
→ Brandvoice from Medium posts (not just LinkedIn)
→ Brandvoice from published books
→ Multi-client agency setup requests
→ Timezone switching for global teams
→ 6-month content planning
→ Visual-first workflows (photos before text)
→ and so much more

Every single one made me think: "How the hell did I miss that?"

But here's what I love about this:

Each request is someone saying "I want to use your product, but in THIS way."

That's not a problem.
That's a roadmap.

My Sunday todo list is completely different from my Wednesday todo list.

And I'm VERY excited about it.

This is the fun part.

Real users don't just find bugs.
They show you what the product wants to become.

Get them in as early as possible.

They'll make your product better than you ever could alone 🫡

Big thanks to all beta testers of Ziplined so far. It's gonna be 100x times better real soon!

All founders I talk to ship insane shit every week.

You'd never know. Neither would their customers or leads...

To make you understand; this is how basically all of my calls with founders go:

Me: 
What's been the biggest win this month?

Founder: 
Honestly we figured out how to cut our CAC in half. But it's nothing crazy.

Me: 
How?

Founder: 
[explains a system that would make most marketers lose their minds]

Me: 
Do you post about this stuff?

Founder: 
We do some LinkedIn yeah. Our intern handles it.

Me: 
How's that performing?

Founder: 
Like 300 views per post I think. Maybe less.

Me: 
And you just described something thousands of founders are Googling right now.

Founder: 
I mean... it's just what we do.

Me: 
That's the problem.

I've had 50+ conversations like this.

Founders doing genuinely insane things every single day.

But this is their LinkedIn presence:
→ 1 post every 2 weeks.
→ Written by the intern.
→ 300 views (if they are lucky)
→ It's a company update nobody asked for (a team photo with peter's favorite food because it was his birthday)

You are playing founder on the hardest difficulty imaginable.

And the world has absolutely no idea.

Because your intern's post about company culture isn't doing the job.

You owe the world those wins. 

Your "obvious" is someone else's mind-blown.

Post it 🫡

Monday morning @ 10:00

60 founders got their first weekly LinkedIn email digest.

Shows exactly: 
→ what worked last week.
→ what didn't.
→ their next [x] posting slots waiting to be filled.

I built this email for myself when I kept losing momentum.

The pattern was always the same:
→ Post for 2 weeks
→ Skip 1 day
→ Feel the pain of skipping 1 day.
→ Gap turns into 3 weeks of silence

So I built a system that nudges me every Monday, inside Ziplined.

Basically: my real LinkedIn data and my actual empty slots staring at me.

Now 60 founders get the same thing automatically.

Every Monday:
→ Here's what performed (plain English)
→ Here's what flopped
→ Here's your 7 empty slots for this week
→ One-click to fill them

The accountability I needed to stay consistent.

Now it just runs.

Every Monday. 10am. Automatically.

"Don't use AI for LinkedIn posts!"

Yeah well okay... but we're doing it anyway ⤵︎

Let me sketch a scenario:

You just shipped something you're proud of.

You (in ChatGPT): 
"Write a post about this."

ChatGPT: 
"I'm thrilled to share that I've been reflecting on my recent learnings about the power of rapid iteration..."

Delete.

You try again: 
"No. Just say: I built image uploads in 3 hours. Users asked for it. I shipped it."

ChatGPT: 
"It's not about the feature. It's about the journey. The goal? Building with intention."

Close tab. 
Go cry in corner. 
Live to post another day.

Your ChatGPT just can't seem to write something you'd be okay reading out loud.

So now you're stuck with 3 options:
→ Spend 45 minutes editing it into something human
→ Stare at a blank doc and give up
→ Just don't post (it's been 3 weeks anyway)

What hurts me the most about this:

The story is RIGHT THERE. 
It's just needs a capable AI to translate your story into something publishable. 

That's why I'm building Ziplined.
It basically upgrades your ChatGPT/Claude to be an 0.1% LinkedIn Content Expert. 

Just to make sure your beautiful stories and insights get some eyeballs on them. 

You probably need it.

Because that 3-week silence is just too painful.
