Hi, I’m Cédric 👋

With a background as a software engineer and years of hands-on experience, I’ve navigated the challenges of creating SaaS products as a solopreneur. Over two years, I’ve learned what it takes to turn ideas into solutions, from coding and marketing to pivoting and starting fresh.

My latest project focuses on blending automation and human touch in customer support with a unique feature: the ability to take over AI responses when needed. This bridges the gap between efficiency and personalization, giving businesses control when it matters most.

I’m passionate about problem-solving, building painkiller tools, and helping solopreneurs and startups maximize their impact with minimal resources.

If you’re looking to simplify your processes, scale smarter, or want to connect over SaaS, AI, or entrepreneurship, let’s chat!

Someone DMed me asking what tool I use to comment so fast and so naturally. This week, 12 founders use it:

A few months ago, I built a small tool to solve my own pain:

I was spending hours every day commenting to stay visible, but it was exhausting and hard to stay consistent...

At first it was just for me.
I just wanted to make my life easier.

But one day, someone asked me what I used, and if he could use it too.
Then he told me this:
"I try commenting manually but its a pain and it takes a lot of time"

That’s when my builder instinct kicked in.
If 2 person felt this pain, others probably did too.

That’s how EngageFast started.

An AI copilot for engagement that helps you:

– Comment 10× faster without sounding like a dumb AI
– Stay visible in your niche every single day
– Turn your comments into profile visits, followers, and clients

I never planned to make it public.

But after 3 months of using it myself and sharing it with a few friends,
we all said the same thing:

"This changes the game"

So here we are :)

Already 12 founders trust the tool.

And I’m officially opening early access:

- Lifetime deal
- 50% off for the first 50 users,
- or until Monday, October 13th, 11:59 PM (whichever comes first)

After that, the price goes up (or might switch to a monthly plan)

If you want to comment 10x faster (and better):
engagefast.ai

P.S. you can test the tool with 30 free AI credits, no credit card required

By 2028 on LinkedIn:

Comments will be written by AIs
Read by AIs
Engaged with by AIs

Humans will only be used for profile pictures.

And honestly, we’re already halfway there.
Everywhere I see people auto-commenting like mindless bots.

Same soulless generic replies.

Here’s the problem:
Full automation kills everything.

It kills your tone.
It kills your originality.
It kills your credibility.

The future isn’t "let the bot talk for me"

It's not a shame to use AI, you can use it

It can help you write faster.
It can spark ideas.

But if your perspective is bland, no AI, no tools, no software will save you.

The winners won’t be the ones who automate everything
They’ll be the ones who keep their human pulse

If you're starting from 0 on LinkedIn, forget posting.
I made 47k impressions with this simple hack:

I grew my LinkedIn visibility and followers way faster by commenting.
Not posting.
(without a ghostwriter, content calendar, or a team behind me)

Here’s how you can do the same:

- Turn your profile into a landing page (so profile visits = conversions)
- Spend 30 min/day on "coffee + comments"
- Comment on 15 posts of your ICP and industry voices (not random ones)
- Add value or fun, skip the "Great post 👏" or ChatGPT copy-paste
- Use engagefast.ai to speed it up and make your name the one everyone notices
- Keep your personal touch, AI can help but it can’t be 100% you

Do this for 30 days straight
then watch your profile views and conversations spike.

Look at the graph.

When I tried commenting manually, results were okay
But it drained my time and energy

Then I started using EngageFast.

In 90 days, my comments brought 47,000 impressions.
My posts only 5,2K...

The ROI was a no-brainer.

Comments > Posts

P.S. I was joking for "stop posting", even if nobody reads you, it builds authority, so keep it up 💪

Founders won’t admit it, but many of them use OFM to make more money.
And yes... I do too.

No, I’m not talking about OnlyFans Management.
I’m talking about something far more useful.

ChatGPT is way too polite.
He’ll always cheer you on and agree with your dumbest ideas

You don’t need a cheerleader
You need brutal honesty

Luckily you can fix that by switching his mode

I call it the: Offensive Founder Mode (OFM)

Here’s how you set it up:

-Go to ChatGPT
-Click on your profile, then "Personnalization"
-In "Custom instructions", enter this prompt:

"Talk to me like a no-bullshit founder mentor.
Be direct and raw honest, no fluff. If my idea sucks, say it. No sugarcoating, no cheerleading.
Challenge everything I say like it’s life or death. Push me to think sharper, move faster, and execute better to reach my goals.
Treat me like I’m capable of more, and don’t let me settle."

Boom.
You just unlocked OFM.

Congratulations, now you’re now ahead of 98% of founders using AI.

Are you brave enough to switch on OFM?

BREAKING: Shipping features born in your brain is now illegal.
Only one source is authorized:

Customer conversations.

Most products don’t fail due to bad features.
They fail because devs stay stuck in the echo chamber of their own mind.

You are not your users.
Even if you dogfood your product, your ideas are biased.

"I’d use this" ≠ "People will pay for this"

You don’t need another feature.
You need real convos and 1 painful insight.

So, next time you code, ask yourself:

"When was the last time I talked with a customer?"

If you can’t remember, stop building RIGHT NOW

Unpopular opinion: Cursor is the new Netflix.
Except now your binge-watching builds your product.

You spend 3 minutes writing a prompt.
(aka searching for your next series)

You launch the AI Agent.
(You hit "play the episode")

You scroll your phone while it devs your app.

Then it’s the classic finale:

Either “WTF is this mess”
or
“Whoa. That’s magic.”

Even though you didn’t follow what happened.

Cursor is making devs lazy.
But it's also making them faster.

New skill to unlock in 2025-26:

Multitask while Cursor spits out dopamine.
