Build a LinkedIn personal brand you’re proud of.

If you’re a founder who’s active on LinkedIn and doesn’t get results, it’s either because of these 2 reasons:


→ You’re not reaching the right people.

→ You’re not saying the right things to get their attention.

You’ve put in hours writing posts, but most of the engagement comes from colleagues, friends, and family, not decision-makers.

You hesitate to post because you don’t want to sound “salesy.”

You keep giving away free value, hoping something will happen.

Meanwhile, the right audience still doesn’t know you exist.

When I partner with you, we fix both problems so your LinkedIn starts working for you:

→ Your profile positions you as a trusted authority.

→ Your posts spark interest from the people you actually want to talk to.

→ Your network fills with the right connections who open doors to opportunities.

Here’s what other founders have achieved working with me:

→ Grew their following 10x in 6 months, attracting the right investors and partners.

→ Started conversations with relevant prospects through content aligned to their values.

→ Built credibility in front of people who could hire them, invest, or refer them.

If you want to make LinkedIn work for your business goals, book a discovery call: ophir-tal.com

I’ll partner with you to manage your content strategy, execution, and delivery in full, while you stay focused on running your company.

All under a fixed monthly retainer with clear pricing and set conditions.

Book your 1:1 call with me (link in bio) to make it all happen, so you can attract the right people, start the right conversations, and open the right doors.

Because I’m a LinkedIn ghostwriter and coach, I work remotely.

Because I help my clients get leads and followers there, and built my personal brand around that, I get paid.

Because of that, I can live as a digital nomad.

And because of that, I’m spending this long weekend in Pai, northern Thailand.

This is freedom through branding :)

LinkedIn content strategy built for clarity and results

No alternative text description for this image

Black Friday Special: LinkedIn Content Strategy that will help you generate leads 🤘


If you're tired of posting without getting any results keep reading.

I'm offering a 1-hour intensive content strategy session that will transform how you approach LinkedIn.

The goal is to build your systematic approach to convert your audience to whatever goal you have in mind (leads, job applicants, podcast interview-you name it).

Here's exactly what you'll walk away with after our session:

THE STRATEGY

↳ Content calendar structure you can follow week after week.

↳ DM conversation starters that actually get responses and book calls.

↳ Engagement tactics that build genuine relationships, not just vanity metrics.

↳ Positioning framework that differentiates you from every other person in your space.

↳ Content pillars tailored to your audience so you know exactly what to write about.

THE PROCESS

We'll spend one focused hour together where I analyze your current approach, identify the gaps, and build your custom strategy from scratch.

After our call, I'll write everything down for you in a comprehensive strategy document. You'll have your roadmap ready to execute the moment we hang up.

THE RESULTS

My clients typically see engagement increases within the first week and start booking discovery calls within 90 days. One founder I worked with recently booked 9 calls in 1 week.

Is it guaranteed? Nope. 

Will you have a strategy to get you there in 30, 60, 90, 120, or 180 days? 

Yes. 

It’s up to YOU how to implement it.

THE DEAL

Normal investment: $150
Black Friday price: $100 (30% off)

This offer expires Sunday night. 

After that, I’m back to regular pricing.

YOU

↳ Ready to invest one hour to transform your entire LinkedIn strategy.

↳ Solopreneur or founder ready to take LinkedIn seriously.

↳ Looking for a systematic approach, not random tactics.

↳ Willing to post consistently and engage authentically.

This is your opportunity to stop guessing what works on LinkedIn and start following a proven system that generates real business results.

Want in?

Send me a DM and I'll send you the link to book and pay for our 1:1 LinkedIn content strategy call.

P.S. Only taking 10 clients at this price. When they're gone, they're gone.

"I'm here for connection not business" is the biggest lie on LinkedIn.


Every single person saying this still pays for Netflix, buys coffee at Starbucks, and orders from Amazon.

They're literally supporting businesses every day while pretending they're above commerce.

They’re the ultimate hypocrites.

They can’t deny there's nothing wrong with 
doing business on a business platform. 

LinkedIn was literally created for professional networking and business development! 

No one is a mother Theresa who's above making money. 

We all have bills to pay and goals to achieve.

If you want to get clients be honest about it.

People respect it way more than fake altruism.

I forgot to tell you that Anna Pitner and I are now in our 10th country as digital nomads: The Philippines! 🇵🇭

From Makati in Manila, during weekdays:

Build LinkedIn content strategies for people who want to get results & clarity 

Coach clients who want to master content & social selling skills for life 

Ghostwrite on LinkedIn for the founders who want to scale their personal brand 

And in the weekends, explore the beautiful islands of the Philippines.

I'll keep you posted about my experiences here!

LinkedIn strategy built for clarity and results

I'm sick and tired of generic LinkedIn content. And I bet you are too.

"Failure is the stepping stone to success" 🙄
"Here are 5 tips to boost productivity"
"Agree? Thoughts?"

It's content pollution.

The problem isn't that people don't have interesting stories.

It's that they default to sanitized, soul-crushing content that sounds like everyone else.

But your mess is your message!

That time you got fired after calling your boss a narcissistic jerk? 

POST IT.

The product launch that flopped because your audience lied in the market survey? 

POST IT.

The investor who ghosted you but then you saw them at the Starbucks line and hit it off?

POST IT.

I've stopped telling my LinkedIn coaching clients to write  "inspirational" posts.

Now I hunt for their uncomfortable truths. 
The moments that made them sweat.
The decisions that kept them up at night.

Stories people can’t copy,
But can deeply relate to. 

Generic content brings generic results.
Specific content warms potential clients.

They both work.
One against you and the other for you.

P.S. Are you team generic or specific?

What if your personal brand could set you free? That's what my newsletter, Freedom Through Branding, is all about. 

In my substack newsletter, I'm going to share tools, stories and lessons from: 

My life as a professional writer,
As a digital nomad,
And a neurodivergent, 

That will help you become free,
Through the filter of your work online, 
Through your social media, 
Through your content. 

Subscribe to my newsletter, and let's build your freedom together:

https://lnkd.in/dF_av2CA

I show you how to turn LinkedIn into a predictable growth channel without sacrificing your freedom.

Before working with me: 
No calls from LinkedIn. 

After working with me on his branding: 
9 calls booked from linkedin. 

1 hour call, 1 strategy, optimized for results. 
Now, as it’s Black Friday, 

I offer the same kind of session, 30% off. 

If you’re interested in linkedin content strategy that converts, DM me “strategy”

I’ll send you the link to book our 1:1 linkedin strategy session at the discounted price of $100.

Too many founders on LinkedIn obsess over “high ticket” clients, but all they should focus on is providing wonderful services to wonderful people.

Some even give marine animal nicknames to clients…whale client, fish, shark. How degrading! These are people. Treat them with respect and give them what they’ve paid for. 

Someone who pays is always more valueable than someone who doesn’t pay and seemingly has more money. 

Like Dumbledore said: 

Help those who deserve it. 

Clients aren’t high or low ticket. 

They are people goddamit.

Most people think fast success is the goal, but it’s an outcome of slow progress. 

Why? 

The moment learning accumulates,

You succeed faster and faster and faster 

Until fast success takes over. 

But if your goal I fast success,

And you’re moving too quickly without a strategy 

Then you’re like a Carthaginian elephant in 3rd century BCE running amok on its own military.

Believe me, you don’t want to be there when it happens. 

You can win battles without tactics,

And you can't wage your campaign without a roadmap. 

It create slow success first, that teaches you:

- Why systems matter more than luck
- How to lead through uncertainty
- How to handle rejection
- When to pivot vs. persist

All of the above create ongoing speed. 

Take me for instance. 

I've built my LinkedIn coaching business over 3 years.

It felt so slow when I started. 

Every client rejection taught me something.
Every failed post showed me what works.
Every slow month built my resilience.

But now, my content-DM apparatus sustains itself. 

It feels fast now, because it felt slow before. 

Want lasting success?

Stop chasing the quick win.

Start building character instead.

If will pay off-literally! 

P.S. Are you on team fast or slow success?

If you're here for business, be honest about it.

There's nothing wrong with that!
Actually, there's everything right with it.

Hiding behind soft language,
Talking about “connection” and synergy,
Will ruin your journey towards getting results.

Too many founders dance around their goals.

They post about "networking",
when they mean "prospecting."
They talk about "sharing value" 
When they mean "getting leads.

When you're clear about your intentions:

- You stop wasting time
- Your messaging becomes direct
- Your content attracts the right people

The people who succeed online are the ones who own their business intentions.

They say: "I help X achieve Y through Z."

Not: "I'm passionate about connecting with like-minded individuals." 🤮

Your audience respects honesty.
They smell the fake humility from miles away.

So stop apologizing for building on LinkedIn.

Call it what it is: business.

You’ll grow your business faster.

How to become a digital nomad in 90-180 days: 


1. Interview your colleagues and friends (to focus on your strengths)

2. Build a remote service around those strengths 

3. Get 1-3 retainers in 1-3 months

How To Become A Digital Nomad In 90-180 Days 

Why LinkedIn has DMs in the first place?


It wants candidates to message employers.
It wants employers to message candidates.
It wants prospects to message businesses.
It was businesses to message prospects. 

Linkedin even created sales navigator,

To help people find specific prospects. 

SALES navigator. 
Not “synergy” navigator.
Not “connection” navigator. 

Sales, goddamit! 

When people write against sending DMs? 
They’re writing against LinkedIn. 

When people say that LinkedIn isn’t for sales? 
They’re denying LinkedIn their money. 

A platform like LinkedIn can’t say: 

“You’re allowed to message someone if you’re interested in their services, but you’re never allowed to message someone who you see as a potential client”.

If it would have been the case,

The platform would be called North KoreadIn,

Not LinkedIn. 

So get used to it:

The wheel is round. 

One day you buy, the other day you sell. 
One day you look for a job, 
The other you’re hiring.

People wouldn’t be here if LinkedIn wouldn’t make them money in the short or long term.

Those who fail to understand it?

Shouldn’t be on LinkedIn, period.

Ego has 0 legitimacy in business.

Period, period, PERIOD! 

Having experience doesn't mean:

→ You know everything 
→ You have nothing new to learn 
→ You're equipped for the brave new world 

Because those who want to rise in life?
→ MUST be in a constant learning mode.

Not despite of their experience,
→ BECAUSE of their experience. 

A true expert always says “I don’t know!”

I'm a LinkedIn ghostwriter & coach,
→ And still learning new things about LinkedIn.

Software developers are experts in code,
→ And even they have a learning curve. 

CEOs and founders? 
→ If they don't learn, they're toast.

They can be experts in their field, 
But they are not marketers (most of them)
Let alone LinkedIn experts.

They either need to learn how to do it, 
Or outsource to someone who knows.

If they let ego win on LinkedIn, 

God knows how much they're losing in their biz.

So I don't care how old you are,
Or how many years of experience you have, 

Learn or collapse.

The choice is yours. 

P.S. What are you learning right now?

I don’t work with people who hate AI.


As a LinkedIn coach, GPTs that I created are a major part of my work, 

Mixing profesionalism, nuance and effiency. 

I’m deeply excited about the new technology,

It helps my clients who are non-writers start writing themselves with my mentonrship. 

So when people attack AI…They attack me.

They attack my clients who love these tools. 

If you want AI in your toolkit, 

As an aid in your journey to freedom?

I’m the guy for you. 

If you think AI is inauthentic, 

You ain’t my person to work with.

There are 5 types of people in your DMs:


(Get your strategy for booking meeting through LinkedIn here: https://lnkd.in/dkuyTP62 )

→ Type 1: The Valuable Prospect

Needs your help, 
Answers questions,
Cooperative. 
These are your next clients. 
True partners who make your job easy.


→ Type 2: The Self-Denier 

Clearly needs help but waves their "million years of experience" flag.

They're drowning but won't grab the life preserver.

Leave them to drown. 


→ Type 3: The "Best, Name" Guy

Still living in 1995, 
Treating DMs like formal work emails.
“At this time I’m not looking to explore this. Best, name) 

AVOID LIKE PLAGUE. 


→ Type 4: The Helper

Can't afford you now but happily refers others.
These people are networking gold mines.
They will build your pipeline long-term.


→ Type 5: The Ghoster

Silence is their only language.
They read, they see, they vanish.
Block them after 3 days of not answering. 


Knowing which type you're dealing with saves you hours of wasted effort.

Stop treating everyone the same.

The valueable prospect will convert, 
The helper is worth building a relationship with. 

The rest are not worth your time and energy,

If you want to generate leads via LinkedIn.

I've built my entire DM strategy around these 5 types.

And it's transformed my response rates.

Because once you know who you're talking to...

You know exactly what to say and to WHOM.

Found this post helpful? Repost it ♻️

P.S. How many DMs do you send daily?

Some people want access to your time and experience but believe they shouldn't have to pay for any of it.


I had someone yesterday who embodied this perfectly.

"I have this problem that's holding me back in business."

They connected with me. 
They sent me a DM. 
They initiated the outreach.

But the moment I started asking simple questions to understand their situation, 

They got defensive.

Not because the questions were wrong, 

But because answering them required honesty and responsibility they weren't ready for.

Then came the classic line: "I don't want to go into this. Best, craphead”.

Haha, best? 

This is LinkedIn DMs, not email you weirdo!

They reached out for help, 
Then panicked the second it required depth.

They wanted clarity without commitment.

These are the type of people I block now.

Not remove as a connection, 

I block them entirely,
So they’ll lose access to me forever.

Only people who benefit my brand get access to my content:

- Clients
- Engagers 
- Past clients
- Mentors I’ve worked with 
- Service providers I’ve paid to 
- People who refer me to potential clients 

They all help me grow, 
They all get access to me.

If you can't invest financially, 
The minimum you can do is engage,
Or refer me to someone who needs help. 

If you do neither, then no:

You don't get to consume my content.

I'm here for people who are serious about LinkedIn,

Not those who drain my energy,

And make fool of themselves.

I'm Israeli. 31. Digital nomad with Anna Pitner. We're both copywriters. Currently in Chiang Mai. This is my story: 

Left the 9-5 grind in 2022.

Was stuck in a marketing job I hated. 
Endless meetings about meetings. 
Pointless presentations. 
Office politics. 

Hated every second. 

Realized I'd rather write copy from a beach in Thailand than sit in another "synergy session."

Now we work from cafes, co-working spaces, Airbnbs.

Best decision ever!
No commute. No dress code. No pretending to look busy. 
Just pure focus on client work. 
My girlfriend handles paid ad campaigns. 
I focus on LinkedIn ghostwriting & coaching for founders. 
We're like a 2-person content machine.

I'm neurodivergent and proud of it.

Autism brain means I hyperfocus on projects I love, 
completely ignore stuff I don't. 
Traditional office life was torture. 
Now I work in 90-minute sprints, take breaks when I need them. 
Use AI tools to handle the boring stuff so I can focus on strategy and creativity.

I help founders build LinkedIn presence.

Not interested in vanity metrics. 
Don't care about viral posts. 
I care about posts + DMs that turn into metrics that improves their business.

They can be clients, talent they hire, partnerships.
Been doing this for 3 years now. 

I use AI agents without losing my soul

ChatGPT for ideation. Claude for editing. 
GPTS I built with psychology embeded to help my clients write on their own. 
Why work harder when you can work smarter, and with your own logic incorporated into it? 

My girlfriend thinks I'm obsessed. She's probably right.

Travel is our lifestyle, not a vacation.

3-6 months per location. Long enough to feel local, short enough to stay excited. 

Tbilisi, Bansko, Da Nang, Chiang Mai. As long as there's good internet and decent coffee, we're happy.

That's literally my whole life.

3 years of running a solo business, 2 years of nomading

What else do you want to know?

About my business / my lifestyle / my work?

Before Rabbi Josh Zebberman worked with me on his LinkedIn strategy and ongoing implementation of it: 


He didn’t have a clear system of generating leads and getting engagement on LinkedIn.  

But after 3 months of working with me, has a linkedin system for life!

DMs that book him meetings.
Posts that attract his target audience.
An optimized profile that magnets people.

Now he has something tangible in his hands:

Real tools to generate leads and ideal clients that understand what he offers. 

It wasn’t achieved through LinkedIn ghostwriting.

He wrote the posts,
He engaged, 
He wrote the DMs.

I mentored him,
Gave feedback every week,
Provided my GPTs and frameworks, 
And most important of all, taught a skill for life: 

Conscious and soulful LinkedIn mastery. 

It all began with 1 hour of linkedin content strategy, that then led to a 3 month “done with you” work. 

Do you want to get a system that builds your brand and gets you leads on linkedin,

Without outsourcing your voice and depending on a ghostwriter?

The first step is booking your 1:1 LinkedIn strategy session with me for $150

And once you get the strategy, 

You deicide if you want my “done with you help” in implementing it or that you’re good to go. 

My help is one click away. 

Get LinkedIn content strategy done for you here: https://lnkd.in/dkuyTP62 )

I registered my business as a US LLC last week.

It was the logical next step as more of my clients come from the US.

Now payments run through Stripe, 
Everything is smoother,

My operations match the level I want to deliver.

I updated my LinkedIn location so my profile reflects this new structure.

Sometimes the right move is a simple change in how your business is organized.

When everything is aligned, 
Things just work better!
