CTO @lempire - building the best place to work for senior devs

Helping 1 million businesses grow @ lemlist / lempire 🔥

Experienced Project Manager and Fullstack Developer with a demonstrated history of working in the computer software industry. Skilled in People Management, Management, Scrum, Quality Assurance processes and Web Applications. Strong information technology professional with a Master focused in Artificial Intelligence (Automatic Language Processing).

I've spent 15 years as a project manager, mainly for Airbus in Toulouse. I've always coded applications even in my project manager years, filling some gaps in management tools that were used internally, mainly in C++ before 2004 and then Ruby on Rails after that.

Until I discovered Meteor in 2015. I was so in love that I left my job in 2016 to build 2 startups in 4 years around this technology that were both huge successes for my personal experience and miserable failures financially. That was so fun !

Now working @ lempire, my desire to help people grow their business is fulfilled every day.

Juma (ex Team-GPT)

Me to my wife: 
'Can you fix my profile photo?'

Wife: 
'Done'

Love is blind.

But also...
LinkedIn algorithm is so horrible these days that it deserves nothing less.

To anyone who writes comments with AI: 
You suck!


A post is like a broadcast- it goes out to all and is hardly personal.
(𝘦.𝘨. 𝘵𝘩𝘪𝘴 𝘱𝘰𝘴𝘵 𝘨𝘰𝘦𝘴 𝘰𝘶𝘵 𝘵𝘰 𝘢𝘭𝘭 𝘮𝘺 𝘧𝘳𝘪𝘦𝘯𝘥𝘴, 𝘤𝘰𝘯𝘯𝘦𝘤𝘵𝘪𝘰𝘯𝘴, 𝘧𝘰𝘭𝘭𝘰𝘸𝘦𝘳𝘴, 𝘢𝘯𝘥 𝘢𝘭𝘭 𝘰𝘧 𝘓𝘪𝘯𝘬𝘦𝘥𝘐𝘯 𝘳𝘦𝘢𝘭𝘭𝘺).

A comment is deeply personal. 
It's the communication between 2 human beings. 
You comment to engage the other person. And you expect them to engage back. 

Slopify your posts and you lose your unique voice.
Slopify your comments and you lose all your humanity.

Our organic traffic fell 95% the day we rebranded. 
45 days later it's still quite bad.

On it's last day (20 Nov 2025), Team-GPT got:
- 1,000,000 impressions
- 2,000 clicks 
on Google.

As of 3 Jan 2026, Juma has:
- 100,000 impressions (90% down)
- 336 clicks (83% down)

We are greatly suffering from the rebranding. 

So what are we doing about it?
1. On page technical SEO (we nailed it)
2. Off page SEO -> building links as the old days, adding Juma in directories
3. PR -> mentions, podcasts, guest appearances, taking interviews in media outlets so we can show up as Juma, not Team-GPT


Rebranding is a long-term investment with short term

We finally launched Juma (ex Team-GPT) officially, together with 250+ people from the AI community. 

Thanks for coming and super excited for what's to come!

In March 2026, we will be revealing the Juma Superagent, an AI system, which can do all types of marketing related tasks, completely on its own. 

P.S.
Video is a short snippet from our Launch Party on 15 Jan 26.

През ноември месец сменихме името си от Тийм-ГПТ на Джума.

Направихме събитие в СФ (Сан Франциско).

Сега е време да направим и в Сф (София)!

Очакваме ви на 15.01 в CampusX.

Местата са ограничени и само с предварително записване:

Here's what Juma can do today.

It's 10x better than 3 months ago.

It will be 10x better 3 months from now.

Interestingly:
- I no longer use ChatGPT... like at all
- Manus rocks and I use it for some tasks (e.g. wide research, slides)
- Grok never resonated with me
- Gemini is useful sometimes but is not a part of my workflow yet
- Perplexity is also not my cup of tea, although I trust it a lot
- Gamma's slides are just too AI generated (Manus is better and soon Juma)
- We pay for Lovable but I'm not the one using it. But I can imagine myself coming back again and again to it

I'm experimenting with other tools but man is it hard to find something that fits your mental model for what AI should be.

We are trying to do

I've lost trust in LinkedIn's algorithm. 
People who are religiously following me don't see my posts. OUCH!
Lots of my content and following is here but the algorithm is rewarding AI slop and my content has lower visibility. 

(to make sure you see my posts, hit my profile and subscribe for updates via the 🔔 bell).

But nobody will actually hit the 🔔, though.

So what am I supposed to do?

Moving to another social media (e.g. TikTok, BlueSky, etc.) has the same risks- algorithm is not aligned with creators but with the platform overall.

The only place where my content-creation efforts are truly safe forever?
My own website.

It has never been easier to build a website. 

Yet I decided to go for a blog (used Substack).
Website designs come and go. 
Letters are forever.

Created. Crafted. Curated.

Changed my profile photo- I hope you are happy...

Putting the ultra-close-up resulted in 40% increase in views of my profile.

Works.
Wondering if it affected our sales and how.

2 months after rebranding, SEO is improving...
(only) 80% decline in organic traffic!

𝗕𝗲𝗳𝗼𝗿𝗲 𝗿𝗲𝗯𝗿𝗮𝗻𝗱:
~1,000-1,500 daily clicks
Average position: 10.3
"team gpt" query: 5,775 clicks
CTR: 0.55%

𝗔𝗳𝘁𝗲𝗿 𝗿𝗲𝗯𝗿𝗮𝗻𝗱:
~400-600 daily clicks
Average position: 14.0
"juma" query: 1,040 clicks
CTR: 0.53%


Interestingly, CTR stayed almost identical. The issue isn't engagement. It's visibility.


According to AI, the recovery timeline is:

Months 1-2: Stabilization ✓ (we're here) 
Months 3-4: 20-30% recovery 
Months 5-6: 40-50% recovery 
Months 6-12: Full recovery with active SEO


Was the rebrand worth it? Absolutely.

Team-GPT made sense when we were a ChatGPT wrapper.
Juma reflects what we actually are: AI agents for marketing teams.

The traffic will come back. 
But it really hurts.

AI sucks at Math. 
Juma doesn't. 

If you are looking to analyze your data- 
whether Excel files, CSVs or others, we run real calculations on your numbers.

You can create graphs, charts, or even Lovable-like websites with the results.

The future is now, old man.

Time for AI to do the Math.

P.S.
Charts are actual Juma data.

I came home for Easter.

I couldn’t do it any longer.

After 2 months abroad, the fundraise was not yet done. This meant the company would seize to exist, I would have let down everybody involved.

Came home to my family to celebrate.

They were hoping for me to talk about the whole experience. However, all they got was an Iliya who was not speaking for days.

I had been pitching for 15 hours a day, every day. For 2 months.

I didn’t know what to say.

I couldn’t look my father in the eye.

I was trying to smile but it was not coming out well.

graphical user interface, text, application, chat or text message

We like to wait and see what our competitors do.

This helps us solve the problems better than them, hopefully in the BEST way possible.

We know the problems our customers face.

Some call it stealing. 

It's actually called research.

Or more posh: second-mover advantage.

My top course is The Data Science Course: Complete Data Science Bootcamp.
It has 791,462 students and a rating of 4.5 by ~159,382 people.
We've now automated it with an agent.

Everything that was thought in this course (and many others) is now fully automated by the Juma agent. 

Our agent turns complex data into reports, charts, PDFs, and presentations - all in one chat.

In this video, we:
- analyze 90-day GA4 dataset
- create visualizations
- generate a website
- build a PDF
- make a PowerPoint deck. 

The data analysis agent is just one tiny bit of what the Juma superagent will be able to do.

Stay tuned!

We are building the place where 'anyone can market anything'. 
Marketers cringe when they hear it.
Mainly because they think marketing skills are hard.

But what makes a great marketer? Think: Steve Jobs, Elon Musk, Kim Kardashian, most recently even Timothee Chalamet..

I think it's: 
- strategic thinking
- 6th sense for what works
- curiosity and willingness to experiment
- understanding of marketing mix and multi-touch interactions (even on a subconcious level is enough)
- taste!!!


What most great marketers can't do:
- Run ads
- Edit videos
- Set-up Google Analytics
- Write SEO-optimized articles
- Know where to find stuff in HubSpot lol

Don't get me wrong- I have deep appreciation for marketing specialists who can do all these.

But keep in mind:

-> The first list will remain human
-> The second list is being automated as we speak

Some professions have it easier, when it comes to AI adoption:

- Developers work in repositories, which they unify through GitHub for instance. So it’s already super organized: you connect the repo and it has all the Context for the project at hand.

- Marketers work on campaigns, which often have a start and end date and must be executed rather fast, context is created at the start and evolves for each campaign

- Agencies collaborate on clients, ideally in the span of years, so they often have this stored somehow

More often than not, context is scattered across tools, drives, archives.

An absolute key step to adopting AI well for your organization is to cherry-pick the right context that the AI will be stepping on.

This is so important, that nowadays we often talk about Context Engineering as opposed to Prompt Engineering.

Context is King.

Full thoughts: https://lnkd.in/dsZvEe6t

How is it possible for a human or AI to create this ridiculous outbound message?

I made a Loom for Team-GPT with ideas on promoting "JUma marketing Super agent".

It's really, really hard to get it this wrong.

graphical user interface, text, application

I think ~200M people total will be needed for most work in 15 years.
After teaching AI to 1.5M people, founding a Silicon Valley-based marketing superagent (Juma), and helping 75K+ users across 500+ companies adopt AI for their work, here’s how I think people, organizations, and corporations should and will adopt AI.

---

I’ve been thinking a lot about the best path to AI adoption.

How do you learn it? How do you teach it? What does it mean to adopt ChatGPT well? What is stopping teams from adopting GPT? Where is the resistance coming from? Why are people achieving such wildly different results? Why does MIT state that 95% of all AI adoption projects fail?

Most humans will be left behind.

Since ChatGPT came out the world really changed. This technological leap is historically unmatched. The world economy is majorly, irreversably, and inevitably changing and technologically advanced nations and individuals will have much better outcomes in life on average.

The problem is that many people who I respect are denying or soft-denying (not using) AI. Maybe 1 in 5 of my friends use it passably well.

We just codified our values at Juma. 

Not because we like being corporate. But because culture wins in the long run.

Here's what we stand for and what we reward:

1. Default to Open
- Share publicly
- Admit mistakes early
- Challenge ideas, not people

2. Own it End-to-End
- Finish what you start
- Deliver on commitments
- Escalate early with a plan
- Choose company wins over local wins

3. Build Great Stuff
- Start with user problems AND business value
- Measure impact 
- Hold a high bar, but ship anyway
- Sweat the details
- Deliver in short term but build for the long term

4. Learn Fast, Ship Smart
- Prioritize ruthlessly
- Test assumptions early
- Learn from mistakes
- Adapt fast

5. Earn Your Spot
- Results over politics
- Same standards for everyone
- Give honest feedback
- Be coachable

6. Set the Standard
- Represent Juma with pride
- Set the bar for the AI ecosystem
- Show up for each other as people


Note:  
This is not wishful thinking. 
It's literally what our culture is- we just wrote it down.

Same expectations. Same standards. For everyone.
