Founder & LinkedIn "Baddie" Business Coach 😈

I can help you confidently sell your 4- or 5- figure offers on LinkedIn and get high-calibre clients so you can generate more revenue for your biz, raise your prices and work less!

I’ve been in Albania the past 3 weeks and here’s what I’ve been up to:

(I left Valencia to explore other cities I may want to live in Europe since my business is 100% remote.)

1. Living in a cash society.

Albania is 90% cash which has made my weekly money ritual where I pull my expenses a nightmare.

I’ve been logging my expenses in the Tricount app to track my expenses accurately.

2. Building out N8N automations.

I’m taking 1-2hrs every day to build out new automations for my business so I can teach my clients to do the same.

This week I ran a temporary Cloudflare tunnel to authenticate Slack with my local N8N instance which was totally new to me (but free.)

3. Running by the beach

I recently went through a medical procedure where I couldn’t work out for 1.5 months so I’m back to moving my body and there’s nothing better than running by the beach.

4. Tonnes of outreach

I’m done doing 100% inbound lead gen and have been doing proactive warm outreach to create more opportunities and it’s been working amazing.

Running a 100% remote business while travelling has been amazing but there’s been a lot of adjustments.

What have you been up to this past month that’s interesting to share? Would love to compare notes in the comments.


P.S. Things are super quiet in Durres, Albania because it’s more of a summer city but we’ve found a fun sheesha bar where 2 Albanian singers are about to come on.

🧠 Build a team of AI employees that think like you & scale as a founder without a big team. //Make AI the operator, you be the visionary 👑 //Ex-product manager in tech 👩‍💻

No alternative text description for this image

Why I proposed using Gemini inside a recent AI pilot I designed for a company instead of building a shiny new AI tool.

A lot of AI consultants want to come into a company guns a’ blazing to build fancy new AI tools because more AI = more ROI, right?

Nope.

With this company, I heard the founder talk about a culture of resistance to AI inside the company. Specifically, a fear of AI taking their jobs.

I also heard him say that the latest procurement of an AI tool got delayed.

So I knew the easiest way to quickly bring in ROI was to train the team to use an AI tool they already were using in their daily workflows, just better.

There’s nothing worse than bloating your organization with more AI tools without first fully leveraging the tools you have at hand.

A Gemini Gem may not be as “fancy” and “impressive” as the latest AI tool on the market, but it’s the perfect way to get a quick ROI lift.

0 friction, 100% adoption.


By the way, if you're a founder, CEO, COO or CPO of a growing company that's looking to unlock revenue by solving for bottlenecks between your CS and/or Product teams, DM me and we can chat about designing a pilot together.

If you think that using AI in your sales means setting up full-blown automations that spam all your connections, let me give you a different perspective.

While yes, there is a lot of that going on LinkedIn (🙄), I want to show you how I use AI in my sales while maintaining a human-centred approach.

Basically, I still write all my outreach messages and DMs myself.

But I use AI as my operator in the background to help me have better conversations.

Here’s what that looked like for me last month:
→ 19 leads generated
→ 9 sales calls booked
→ 6 opportunities generated
→ 3 deals closed, 3 still in the pipeline
→ Every message still written by me

This is what I did behind the scenes with AI:
👉 Used AI to research prospects on LinkedIn to get ideas for potential angles for my outreach messages
👉 Analyzed DM convos to spot buyer intent and guide the convo naturally to a sales convo
👉 Reverse-engineered the posts driving inquiries + profile views to understood why they worked
👉 Prepped for sales calls by uploaded all context into AI + layered in frameworks like Never Split the Difference
👉 Broke down sales call transcripts after to craft sharper follow-ups and spot what I missed in real time

Zero automation I have no control over.
Zero fear that my messages didn't sound like me.
100% confidence I'm still selling as a real human being.

The part I love the most is how using AI as my co-pilot like this allows me to see my blind spots and become way better at sales way faster.

So many of you have been approaching me the past few weeks for help with generating business leads on LinkedIn using AI while maintaining a human-centred approach.

I'm going to be sharing something very soon where I'm not only going to teach you how to elegantly leveraging AI to get clients on LinkedIn (without losing the human touch), but I'm also going to guide you as you implement these strategies alongside other founders just like you.

I'm so excited, I can't wait to share more!

Nov 2024: running a scooter rental business in Tulum, Mexico.

Nov 2025: helping businesses solve revenue bottlenecks with AI systems.

Here's what I've learned about launching & pivoting businesses as a 7x entrepreneur (with lots of failures too.) 👇

1. Move as soon as you sense demand.

I've never waited to have the perfect branding or website to start a business. The moment I detect demand for a service, I take messy action and start serving clients right away.

2. Don't wait until you feel like you know everything.

You learn most things on the job and waiting until you're an "expert" just delays you from getting started.

Remember: there's always someone a few steps behind you and throwing yourself in the deep end is how you're forced to learn quickly.

(Plus, for my scooter rental business I could always ask ChatGPT which handle break controlled which tire so I was good. 🤭)

3. Know that you can always reinvent yourself.

There's nothing more painful than holding onto an old business or old identity. If you've built (or tried to build) a business before, you can totally do it again!

4. Different niches/business models... same foundations.

I thought operating an in-person physical business would be completely different. Like unrecognizably different.

But at the end of the day, it was the same mechanics (pun intended) in the back-end.

5. Pivots can take months to fully complete.

I used to think pivots were something you did in 1-2 months, but this year has taught me that it can take way longer for you to truly settle in your new zone of genius.

Entrepreneurship is such a humbling experience.

Have you launched or pivoted multiple new businesses in your time as an entrepreneur? What have you learned?

Thirty minutes before my keynote, I deleted my slides. Raw, real AI in action on stage.

No script. No safety net. Only the tools I actually use-every day.

Standing in Istanbul, right where I grew up, I showed the crowd what AI looks like in my life as a founder.

Gamma for sales decks and follow-ups in minutes. 

ChatGPT for client projects, workflows, and brainstorming. 

Granola for note-taking-my notes, AI’s notes, everything in one place. 

Make brings me a personalized podcast every morning on the drive from the school drop.

No theory. No hype. Only what works.

The energy in the room? 

Wild.

People said it was one of the best keynotes they’d ever seen. 

I felt it, too. 

Because when you show up real, people get it.

We all want the same thing-AI for better lives, smarter work, stronger teams.

That’s my North Star. 

AI Operator helps businesses use AI to move faster, work smarter, and grow stronger. 

But for me, it’s even bigger. 

AI for better lives. 

Helping people and companies thrive, not just survive.

Met some new partners. 

Spoke with founders who get it. 

We’re building a global movement.

If you still haven’t trained your team to use AI, you’re missing out. 

End of 2025, the gap will be huge.

Jump on the train now, or risk getting left behind.

Let’s chat-I’ll help you create a clear plan.

Making the AI transformation mountain climbable for ambitious SMBs | Strategic partner from base camp to market leadership | Guaranteed ROI

Google Gemini went from 1% of my workflow to my main focus overnight.

Three months ago, I barely touched Gemini.

Now? Everything changed.

Google dropped Gemini 3 Pro, Anti-Gravity, Workspace Flows, AI Studio.

Big shift.

Before, Gemini felt like a sidekick. Fun, but not serious.

Now, it’s the real deal.

I trained Google teams on Gemini. Yes, their own tool.

Wild.

Back then, I thought Gemini was slow, behind ChatGPT and Claude.

But now, Gemini is catching up-fast.

Even my Perplexity usage dropped by 90%. Gemini is taking over.

If your company lives in Google Workspace, you need to pay attention.

Gemini is built for the workspace. The tools are getting strong.

AntiGravity’s agent manager? Next level. The logo? Solid.

Google is stepping up. The AI race is heating up.

I still train teams on ChatGPT. But soon, Gemini will be the main player for many.

Teams who wait will miss out.

2026 will be huge for those who adapt. Disappointing for those who don’t.

We run a 12-week program to make teams AI masters for 2026.

Four spots left for Q1.

Want your team to catch that energy? Reach out.

I built a complete B2B sales system using Claude Code (using the new Opus 4.5 model)… And this beast F*CKING RIPS!!! 🤯 You gotta see this…

It has access to my entire 9-stage deal pipeline:

1️⃣ Lead
2️⃣ Call One Scheduled
3️⃣ Call One Complete
4️⃣ Call Two Scheduled
5️⃣ Call Two Complete
6️⃣ Proposal Sent
7️⃣ Closed Won
8️⃣ Closed Lost
9️⃣ Nurture

Here's what makes it effin insane:

The Meta Agent is the orchestrator. It never does the actual sales work - it's the traffic cop that routes everything to specialized sub-agents:

→ Researcher Agent - Deep company intel in minutes (not days)
→ Call Prep Agent - 3,000+ word custom prep docs per prospect
→ Analyzer Agent - Extracts MEDIC framework data from call transcripts
→ Materials Agent - Creates proposals, emails, decks, custom programs
→ Tracker Agent - Updates pipeline metrics automatically

Every company gets its own folder with:

→ Deal context (JSON file)
→ Company research (Markdown)
→ Contacts file with stakeholder personalities & priorities
→ Pre-call strategy
→ Call transcripts
→ Follow-up materials

It's crazy.

And instead of me doing the work myself, I designed a system that does the work for me.

❌ Manual data entry → ✅ Auto-populated by agents
❌ Generic templates → ✅ 3,000+ word custom prep
❌ Memory in your head → ✅ Structured deal context
❌ Hope-based follow-up → ✅ Proactive stall detection

The result?
The system does the work. I do the calls.

I was about to hire a salesperson. Now I'm automating 80-90% and just showing up to close deals.

Two active deals in the pipeline since I built this last Thursday.

👇 And here's my CRAZY offer to you:

I plan to spend 5–10 hours in the comment section of this post. All you have to do is comment WHAT TASK you'd like to automate in 2026. Then, I will comment back with the exact approach I would take if I were you.

Free consulting. Let's go!!!!

PS: We run trainings on how to design systems like these inside your company. Send me a message and let's hop on a call.

I use Claude Code for non-code tasks. The results are ridiculous-nothing else compares.

Claude Code has a name that tricks people.

Most see “Code” and think it’s only for developers.

But the real magic? It runs business operations.

I use Claude Code to set up workflows, build agents, and give them skills.

These workflows turn into systems that run my business.

Folders become entire operations. Agents handle tasks. Skills automate what used to take hours.

I see a boost in efficiency that is wild.

Other AI tools are not in the same league for non-code work.

My computer runs on Claude Code workflows for:
→ Onboarding new training clients
→ Updating training status
→ Automating reports
→ Chaining tasks across tools

No copy-paste. No manual follow-up.

I train teams to use Claude Code for their daily roles. Not just for code, but for everything else.

When people only use it for coding, they miss out.

AI is not perfect. But with the right workflows, it becomes your best teammate.

Miss one step and you leave value on the table.

Want to see what this looks like in your company?

Let’s chat-I’ll help you create a clear plan.

Excuse my French, but we BEEEEEP do AI training right. Here’s why it works.

I keep seeing big voices say AI training isn’t a thing.

Wild.

If you think giving your team access to tools is enough, you’re missing the point.

You need a mindset shift. You need to change how people show up every day.

AI training is not “let’s teach engineers to use another tool.”

It’s about helping every single employee rethink how they work.

First, we start with curiosity. How can AI make your job EASIER, FASTER, SMARTER?

Our 12-week AI First Mindset program is not a box-ticking exercise.

It’s a live show. One hour a week. Real assignments. Practice groups.

We cover the basics-prompting, context, memory, connectors, tools like ChatGPT, Claude, Gemini, Copilot, Gamma, n8n, Make, Zapier, and MindStudio.

But that’s just the start.

Next, we rip up old workflows and build new ones together.

Your team learns to reimagine their own daily work-with AI as the Swiss Army knife.

Final weeks? Advanced stuff. Custom GPTs. Automations. Real business impact.

Week 12 is our innovation competition.

Teams pitch new ideas. First place gets a spa day. Third place, Amazon voucher.

The energy? INSANE.

I’ve seen teams go from fear to excitement in weeks.

They become AI champions. They save hours. They lead the change.

AI training is not “extra.” It’s the difference between falling behind and leading your market.

If you're on board, just comment "Buyakasha" for fun! 😉

I have already saved 7 hours by talking to my computer instead of typing.

Wild, right?

Last year, speaking instead of typing felt awkward. I kept reaching for my keyboard out of habit.

But I decided to change. I forced myself to use voice tools for work.

Aqua Voice is my go-to. The desktop experience is strong. Transcription is sharp.

I paid for a year-no regrets. Seven hours saved already.

Here’s what I learned:

→ Talking is natural. Typing is slow.
→ I make fewer mistakes when I speak.
→ My thoughts flow better with voice.

I set up shortcuts. Stream deck button, FN key, world key. One tap, I start talking. Two taps, it listens and types.

No more grammar worries. No more typos. No more backspacing.

Now, I’m building a new habit. Less typing, more talking.

Productivity BOOST.

If you want speed, try Aqua Voice, WhisperFlow, or SuperWhisper. Pick one. Test it for a week.

I’m hoping for a mobile app soon, but desktop is enough for now.

You can speak your mind and get work done faster.

What tools are you using for dictation?

I’m going live to break down Claude for real business automation. Join me Friday and bring your hardest questions.

You know my live events. Always raw. Always hands-on.

This Friday, I go deep on Claude:
→ Claude’s workspace-projects, artifacts, connectors
→ Chrome extension-real help while you work
→ Claude Skills-new feature, big impact
→ Use cases for every team-marketing, dev, ops

Want to automate daily tasks? Build repeatable workflows? Scale business-wide?

Claude can make it happen.

Bring your questions. No experience needed. The session is super interactive.

If you lead a team, run a business, or want faster work, this is for you.

I’ll show live examples. You’ll see how Claude fits into real workflows.

No slides. No fluff. Live action only.

Friday. November 21. 12 p.m. GMT.

Follow AI Operator LinkedIn page and check the events section-don’t miss out.

Which part of Claude are you most curious about? Workspace, Chrome, or Skills?

I learned the four agreements at 36. They changed my life at 37.

For years, I handled setbacks like a classic founder-push harder, move faster, never stop.

But something was missing. I kept hitting the same walls.

Then my business partner David handed me a book. He’d mentioned it before. I ignored it.

But this time, I read The Four Agreements. And everything shifted.

Here’s what I pinned to my wall:

→ Be impeccable with your word. I learned words matter—they shape how I see myself and lead others. I make sure to say only what I mean. I use words to lift people up, including myself. Less self-criticism, more progress.

→ Don’t take anything personally. No one else sees the world the same way you do. People act from their own reality. Now, when feedback stings, I remember Tim Ferriss’ rule: 10% will always take things personally. I treat it as math, not emotion.

→ Don’t make assumptions. Assumptions create confusion and conflict. I ask questions and keep my mind open. I set healthy boundaries and seek clarity. When nothing is clear, I ask again. Strong teams ask—no guessing, no extra stress.

→ Always do your best. Some days my best looks like 80%. Other days, I only have 40%—so I give that 40% my all. Jim Kwik taught me: if you give all you have, you gave 100%. Show up, learn, move forward. No guilt. No looking back.

These agreements turned my setbacks into setups for growth.

I used to wish I’d learned this at 25. But I’m grateful I learned it at all.

Now, under30ceo featured my thoughts in their article on resilience. Feels full circle.

We learn from those ahead of us. We pass it on.

That’s the mission.
