Not sure where to start?

I built engagefast.ai to help you comment 10x faster without sounding like a bot.

4. Be consistent, it's like going to the gym: you don't see results day 1
5. Use AI to go faster, not to replace your brain

Comments are distribution you control.

Posts are a lottery.

5 things I learned about comments in 2025:

1. Speed matters, comment on a post > 48h is useless
2. Show up where your audience already is
3. Add something : perspective, joke, punch, controversial, experience etc.

But most people treat comments like an afterthought.

They spend 2 hours writing the perfect post.
Then drop "Great insight" on 3 posts and wonder why nothing happens.

No matter what format wins.
Posts, videos, carousels.

They're all worthless if you're invisible in the comments.

They came from:

- 40 seconds on a comment that bring 5 leads
- Dropping replies on my creator's post, got 50+ views on my profile
- Commenting on 20 posts, got 3 DMs asking about my product

Weird that the "secret" was hiding in plain sight the whole time.

Spent $$$ on AI image credits instead of buying a real one.

Worth it.

Dude's commenting faster than the truck accelerates.

Apparently the Tesla touchscreen gives him superpowers.
(or maybe that's just the tool who knows...)

Either way, check the pic.

Every mistake you made 1 year ago is proof you're not the same person anymore.

The graveyard is full of perfect things that never shipped.

Ship broken.
Learn fast.
Grow faster.

I used engagefast.ai and crushed a week of work in under a minute.

Still think posting is the only way? 😏

Google Sheets is great for tracking expenses and formulas
Not for professional stalking
December 10, 2025 at 1:15 PM
So I stopped.
Now I manage this with engagefast.ai directly in LinkedIn.

- I easily built my lists of people I want to engage
- I don't have to update a messy Google Sheet
- I can open a custom feed with their posts only
- I can finally engage with them without being creepy

+ they all got a notification that I visited their profile.

Nothing says "I'm tracking you in a spreadsheet" louder than showing up in someone's profile views 5 days in a row.

That was suuuper cringe.

And Google Sheets was terrible at tracking who actually posted new content (manual refresh hell)

So, whatever you want to do,
just start,
it's worth the mess :)

But I kept going.
And now...

I built Keepcalls -> got to $4k
I built engagefast.ai -> growing it daily

None of this needed special talent.

I just started before I figured it out.
And refused to stop when it sucked.

The black box stays black until you open it.

So I did the same and I launched my first SaaS anyway.

- 6 months of building.
- 2 users.
- Both churned in week 1.

Wild.

I made every possible mistake a first-time founder could make.
December 9, 2025 at 1:15 PM
Tbh I thought I needed some secret founder gene I didn't have.

So I delayed for months.

Then I realized something.

-> every founder I looked up didn't start knowing this stuff either.

They just started.
F*cked up.
Learned.
Kept going.

You can spend 6 months growing an audience to make posts work. Or you can start selling this week with comments.

Your choice.

6️⃣. Turn your profile into a sales page

When someone reads your comment and clicks your profile, they need to instantly understand what you do.

Skip the clever tagline, just say clearly what problem you solve and for who.

If a good comment drives traffic, a good profile converts it.

5️⃣. Make them want to click your name

Just be interesting enough that people wonder who you are.
That curiosity drives the click.
