It started as a simplistic WordPress website showcasing our portfolio of courses. With time, our team started growing and we developed more complex software solutions until we launched our own learning management system and developed comprehensive in-house marketing expertise.

My role was closest to that of a COO. My OCD has always been preoccupied with structuring work and developing processes in order to never miss a step or a deadline. Therefore, scaling our team and processes was more of a relief (of my obsession for structure), rather than an occupation. 

But as a co-founder I have worn many different hats with the C- in front: CFO, CTO, CMO. Nonetheless, I have never neglected the specific business driving activities of our industry, such as creating and editing content (video and text), content dissemination (automatic, semi-automatic, and unfortunately, at times, manual), social media management automation, technical SEO, tracking, ads management (running Facebook ads until my last day) and probably many more.

On the managerial side, apart from overseeing most processes, I was head of content creation and have personally read and edited all the educational content that came out of 365 Data Science. This has proved invaluable for expanding my programming knowledge base and providing me with incredible breadth of data science skills (all types of statistics and machine learning, incl. regressions, clustering, dimensionality reduction, credit risk models, price elasticity models, visualizations, feed-forward neural networks, convolutional neural networks, and more). 

In December 2020, I exited 365 Data Science to devote more time to other projects.

CEO @ Team-GPT | 1,300,000+ AI students on Udemy

👉1 sentence about me: 
I teach AI to 1.5M students on Udemy; also CEO of Team-GPT: A leading Enterprise AI software. 

👉Multi sentence about me: 
I used to compete in Maths for 10 years and was quite good at it. To this day, my work ethic is highly influenced by my Math competitor days.

I graduated in Finance and have all the financial knowledge I could ask for. It was not my calling, so I never pursued it... but I find it quite useful in running a business. 

At 23, I co-founded an educational startup for online data science courses - 365 Data Science. I helped it scale to 30+ people with millions of students worldwide and $1M+ ARR. Courses that I have personally created have been taken by 1,300,000+ students. This EdTech business was bootstrapped to $30M+.

Currently, I'm Co-founder and CEO of Team-GPT. Team-GPT reached 25K users in 9 months and is used by enterprises all around the globe.

I'm a very curious guy, who loves to build stuff.

You got into marketing because you love the work. 

The strategy. The creative. 
The moment a campaign clicks and everything comes together.

But that’s buried. 
Dozens of tools. Hundreds of workflows. Endless details.

You spend more time managing systems than creating. 
More time switching contexts than turning ideas to life. 
More time explaining what you're doing than actually doing it.

This isn't what you signed up for.

Marketing should be simpler. 
Much more delightful.
More like... Juma!

-

Juma is the workspace where your team does their best work.

Everything you need to plan, create, and launch lives in one place. 
Your team has the same context. The same tools. 
The same ability to move fast. 

A place where work stops feeling like a burden.
Experience the joy of marketing.

Think together, move as one!

CEO @ Juma | 1,500,000+ AI students on Udemy

Когато пиша за политика, алгоритъмът се обърква, тролове коментират, маркетинг стратегията ни пропада, а бизнесът ни страда.
Но има нещо от което бизнесът ни, както и на много други българи, страда повече.

Това, че ни спират тока, като им пречим.
Това, че съдебната система е завладяна от мафията.
Това, че взимат бизнеси на хора безнаказано (Илия Златанов от Изамет и Осемте Джуджета, както и десетки неразказани истории).
Това, че държат кмета на Варна 6 месеца в затвора без причина и без присъда.
Това, че саботират полезните действия на кмета на София.
Това, че Европейската прокуратура трябва да се намеси, за да търси справедливост срещу кметове на ГЕРБ и безумията им. 
Това, че САЩ трябва да използва Магнитски, защото сами не можем да се справим с корупцията.
Това, че от години в България няма истинска журналистика, защото разкараха всички достойни журналисти.
Това, че медиите показват каквото им се каже, а социалните мрежи показват истината.

Това, че закърпват държавния бюджет с парите на най-здраво работещите хора. Не за да ги дадат на учители и лекари, а за да приберат парите в джобовете на безкрайно оядени престъпници. 
 

Ние сме хората, които градим, а не рушим.
Които вкарваме външни инвестиции в страната и увеличаваме богатството на България.

Протестираме, защото заслужаваме много повече от прасе и тиква.

New product, who dis?

Soon to empower every marketer in New York.

JSESSIONID

Talks about #ai, #chatgpt, #startup, #buildinpublic, and #entrepreneurship

Now 15,000+ people follow my content here.

I'm the CEO of an AI startup but don't use AI to write on LinkedIn.

Why?
-> I think AI can help with wording.
But it can't help with self-expression.

-> Lots of work will be automated by AI.
But human connection is not one of them. 

-> AI writes cheaper, faster, better than me.
But I mainly write to structure my own thoughts.


That's why I'm on LinkedIn -> 
to structure my own thoughts, express myself, and hope to connect with likeminded people on the way. 


In the last 3-4 years of posting, I shared the good, the bad, and the ugly.
-> Reached millions of AI students with 365 Data Science 
-> Closed 3veta and shared why
-> Built Team-GPT in public from Day 1: 0 to 10K users posts, fundraised $4.5M, posted investor reports, shared deeply dramatic insights, hit $1M ARR, and even posted the OpenAI legal letter suing us


I share because 𝘺𝘰𝘶 have shown me it's useful!
And am thankful for your time. 

.
.
.

P.S.
If you don't know me -> let's connect!
If you know me -> Thanks for being around, I'll continue sharing 🫡

This weekend I finally did it. 
I've been avoiding it for 2 years.
I'm planning for it to last 50+ years. 

It's my personal website, featuring:
- links to my work
- some of my favorite articles and posts
- mini projects (e.g. beautiful QR code generator)

I have a bunch of stuff I've been meaning to publish online but LinkedIn doesn't feel like the right place.

Първи ден на Джума и вече е в новините 😎 

Благодаря на Mary Ivanova и Капитал, че отново разказаха историята ни!

🤖 Преди година, малко след като #TeamGPT привлече 4.5 млн. долара финансиране в рекордна за млада компания на този етап сделка, в лондонския офис на дружеството пристига писмо, адресирано от OpenAI. "В него ни подтикваха да се откажем от търговската си марка в САЩ, Великобритания и ЕС, защото не можем да я притежаваме", обяснява Iliya Valchanov, CEO и съосновател на Team-GPT (българското дружество се казва "Тийм ГПТ").

📧 Екипът от петима бизнес партньори решава да игнорира писмото, защото компанията има запазени марки на трите пазара, одобрени от съответните контролни органи. Разбира обаче, че не можеш да игнорираш OpenAI така, "както можеш да не отговориш на съобщение на мъж след неуспешна среща", смее се Вълчанов...

🌍 Тази седмица стартъпът, който от две години обслужва вече над 75 хил. клиенти в САЩ, Канада и Европа, сменя своето име и търговска марка. Team-GPT вече се казва Juma. Какво се случи междувременно, какво правиш, когато технологичен гигант съобщи, че иска да те съди и какво казва законът? Четете в статията  на Mary Ivanova тук: https://lnkd.in/dJ-2qRqy

Yellow alert!

We are changing everything about us next week.

New name, new agents.

Stay tuned!

Getting from 0 to 10K users was wild.

Revenue: $80,000
Net revenue: $ 47,819.58
Time: 170 days
Users: 9597

Who remembers the first days of building Juma (ex Team-GPT) in public?

- Took us 6 months to make $80K in total revenue.
- Last month we added $80K recurring revenue. 

The scale has changed drastically. 
But we still have the same passion! 
And much better direction.

Here's how we got from 0 to 10K users:
👉 https://lnkd.in/gFXPFhga

Not all $$$ are made equal. 

Recurring revenue is way more valuable than one time. 

Service revenue is easier than product revenue. 

B2B revenue is easier than B2C. 

Enterprise revenue is hard to get, hard to lose.


The goal of each business?
It's not generating money but generating free cash flow.

So it's not about how much money you make. 
It's about how much money is left.

86% of marketers believe AI will benefit their work.
Only 26% can actually execute on it.

That's a 3x gap between confidence and capability.

Many teams are stuck:
- Not decisive enough to commit. 
- No internal drive to manage the adoption.
- Not technical enough to set AI up for success.


The Growth Syndicate made a report which covers 110 B2B marketing leaders and breaks down:

1. Where teams are actually using AI (91% for content, only 20% for sales enablement)

2. Why skills matter more than budget (60% cite training needs vs 25% budget constraints)

3. Much more


My contribution to the report:
"Don't be afraid to make changes to your strategy as you learn more. But with any marketing activity, if you give up after one post on LinkedIn, have you really tested the channel? 
Same with AI tools—commit long enough to learn, then course-correct."

Next week AIEF After Hours is in our office. So I couldn't miss it, even if I wanted to.
But I wouldn't miss it because Rangel Milushev (YC-founder, Harvard gradudate) will be talking about AI.

You should totally come: 
👉

Open article: AIE.F Europe After Hours #46 · Luma by luma.com

To make $1M per year,
you need:


1,000,000 customers paying you $1
100,000 customers paying you $10
10,000 customers paying you $100
1,000 customers paying you $1,000
100 customers paying you $10,000
10 customers paying you $100,000
1 customers paying you $1,000,000


Which one do you prefer?

San Francisco hits different when you're all-in building.

Sure, the investment money helps. 
But it's not about that.

It's about the energy. 
The ambition. 
The history.

The belief that you can actually change the world with a laptop and a vision.

You're the average of the 5 people closest to you. 
When that may be Elon Musk, Mark Zuckerberg, Sam Altman, Satya Nadela, and Jensen Huang you either become a supervillain or you get really ambitious. 

Hope it's the latter.

We're cooking up something that will change how people market stuff.

More soon!

I know these tease posts have been a bit too much...

But I literally have only 2-3 days left to do them.

Stay tuned- 
dropping our biggest update ever next week!

How do you know your outbound sucks?

It's outdated.

I still receive calls for 365 Data Science. 
I receive emails for 3veta.
LinkedIn messages for Team-GPT.

Idk where these people get their data but a message like this kills trust immediately. 

0% chance to work together.

'Dogfooding' means being our own customer.
All successful startups practice dogfooding.

I'm in top 1% of the users of Juma, using AI more than 99% of the people on the platform.

Juma (ex Team-GPT) has saved me ~2 months of work in 2025. 

My favorite capability? 
Projects!

I hate Black Friday.

After building multiple products and runnning many promotions-
Black Friday deals work only for ecommerce.  

- For software, it cheapens the product and the experience. 

- If you do this often, people get used to it and 'wait for the discount'. 

- Loyal existing users feel betrayed that you gave a deal to someone else, while that someone else only chose you cause you are cheap, not because of your value prop. 

+ the revenue is not that much anyways

There is a lot of hype in AI because there has been a big shift in what's possible. 

It's clear a lot of value is being unlocked. 

Truth is- we are all figuring it out. 

👉 We, the builders, are trying to build new age tools which create 10x or 100x more value than existing software for our users. While figuring it out, we are often creating more noise and not making it easier for users. 
(when you have more clarity a rebrand often comes, see us as an example haha)

👉 For AI adoption leaders it's absolutely clear they need to act. But what to do? The best results are seen when:

1) There is a clear owner who is responsible for making sure people in the org use AI. This person should be empowered to make decisions, rollout the way they see fit, and keep going with this decision for at least 3-6 months. 

2) Don't be afraid to make changes to your strategy as your learn more. But similar to (say) LinkedIn posting, if you give up after you post 3 posts on LinkedIn, have you really tried?
Same with the AI tools- 𝗰𝗼𝗿𝗿𝗲𝗰𝘁 𝗰𝗼𝘂𝗿𝘀𝗲 𝗯𝘂𝘁 𝗱𝗼 𝗰𝗼𝗺𝗺𝗶𝘁.

3) Do weekly check-ins with people using these tools. The fact that a tool has been purchased, doesn't mean it is being used. Be on top of it and measure. Make data-driven decisions. 


AI is not overhype.
NVIDIA, OpenAI, and similar are. 

But AI is creating a lot of value. 
But it needs to be harnessed.

When you build something from the ground up, you feel it deeply. 

𝗜𝘁’𝘀 𝗻𝗼𝘁 𝗷𝘂𝘀𝘁 𝗯𝘂𝘀𝗶𝗻𝗲𝘀𝘀. 𝗜𝘁’𝘀 𝗽𝗲𝗿𝘀𝗼𝗻𝗮𝗹.

The past two years I’ve seen every line of every contract, read every seed-round document, and known exactly where 𝗲𝘃𝗲𝗿𝘆 𝗰𝗲𝗻𝘁 went - every salary, every product decision, every single rebranding dollar.

This week, we’re stepping into our next chapter.

A new name that reflects how much we’ve grown and where we’re going.

Thank you, Team-GPT. It’s been more than a privilege - it’s been a journey that shaped who we are and what we stand for.
