In my post from last week, you asked for proof.
Here it is.
I know it's hard to believe...
but yeah, Elon truly doesn't hate LinkedIn anymore.
And now he's running EngageFast.ai from the Cybertruck touchscreen.
He's at 24 comments in 13 minutes.

Engineers are trained to avoid errors.
Entrepreneurs are trained by them.
Your first landing page -> ugly as hell.
Your first cold DM -> cringe.
Your first pricing -> way too low.
Your first product -> built for nobody.

I had a Google Sheet with 50 names of people I wanted to engage with on LinkedIn.
Every day I got the same damn routine:
- open the sheet
- click profile 1
- wait for page to load
- check if there is a new post
- find something to say
- repeat 49 more times
Took me 90 MINUTES / day

Initially, I was a simple developer.
2 years ago I had (literally) ZERO clue how to:
- do marketing
- sell anything to anyone
- talk to users without feeling weird
- get anyone to care about what I built
A total black box.

I'm not special.
I'm not a 10x dev.
I'm not even that good at marketing.
My only advantage?
I wake up and try again.
First SaaS: NeoAssist. Failed.
Zero revenue, zero users who cared.
Family and friends kept asking how it's going.

People say AI commenting sounds fake.
I've been using AI to comment for 3 months.
Here's what happened:
- Zero people called me out.
- Zero fake vibes.
- Actually got more replies than before.
- Actually got more views on my profile than before.

At 24, I felt behind in life.
Everyone on X seemed to crush it:
"Made $50k in 3 months"
"Quit my job and now making 6 figures"
"Sold my startup for $2M at 23"

Thea sent me a DM a few days ago.
She cut her commenting time from 1 hour to 20 minutes.
Just by using EngageFast.
40 minutes saved.
Sounds small? do the math.
40 mins daily
= 5 hours a week.
= 20 hours a month.
= 243 hours a year.
That is 30 full 8-hour work days for one year.

Got 11 replies and 1 customer... 💀
So I switched.
No more cold messages.
Only warm conversations.

No one mentions the 2+ hours it actually takes.
I was stuck in that trap.
Posting daily + commenting on 30+ posts = 2 hours gone every single day.

Here's what I stopped doing as a solo founder:
- posting every minor win like I cured cancer.
- lost 80% of my time on details for 20% results.
- using AI where AI can't replace me.
- pretending my new project is the next unicorn.
- spending more time talking about building than building.

I stopped optimizing my posts and revenue went up.
Weird, right?
Here's what happened:
I used to spend 1-2 hour per post.
Refining the hook, the structure, the CTA.
Result?
-> 400 views, 12 likes, zero customers.

Your first launch will flop.
Even if you started posting 3 months before.
Because building an audience is long and hard.
Really hard.
Sure, 1% get lucky and grow fast.
They go viral once and ride the wave.
You're probably not in that 1%.

Passive income is the biggest lie SaaS solo founders tell themselves.
You know what's really passive?
Nothing.
- Your SaaS needs updates.
- Your audience needs content.
- Your customers need support.
- Your competitors need watching.
The only thing passive is your growth when you stop showing up

Building in public is killing your ability to actually build.
- You spend 3 hours crafting the perfect update.
- Another 2 hours engaging with replies.
- Another hour scrolling to stay visible.
Meanwhile your product sits untouched.
