Three months that nearly broke him. As Irzan Raditya sat across from 90 employees—people he considered family—he had to deliver the devastating news: they were being let go.
This wasn't just another startup pivot story. This was the moment the CEO of Kata.ai had to choose between his company's survival and keeping his team intact. The transition from Yes Boss, a human-powered virtual assistant service, to Kata.ai, an AI-driven conversational platform, would either make or break everything they'd built.
Today, that painful decision has paid off in ways Raditya never imagined. Kata.ai now serves over 200 enterprise customers across Indonesia, processing more than 2 billion conversations to date. In this candid interview, he reveals the brutal realities of pivoting a business, the counterintuitive advice that saved his company, and why local AI startups have a unique advantage that even OpenAI can't replicate.

Key Highlights:
"An entrepreneur shouldn't be falling in love with the technology or the solution. You should fall in love with the problem. Focus on your customers, their pain points and problems and build your solution around it. So it's not technology first, but your customers first."
"I think the opportunity for local AI companies is to solve hyperlocal problems. So if these entrepreneurs could leverage AI to solve local problems with hyperlocal data, that's a winning game."
"It was the toughest three months of my life because I was never being an entrepreneur that running a business full-time and then I was very upset that I had to let go 90% of my staff back then because maybe like they're part of a family."
From Childhood Hustler to Tech Entrepreneur
Tell us about your entrepreneurial journey and how you got started with Kata.ai.
Irzan: Hi, my name is Irzan. I'm the co-founder and CEO of Kata.AI. What we do here, Kata.AI is the pioneer of conversational artificial intelligence platform. We help businesses to improve their customer engagement through the likes of messaging apps such as WhatsApp, Instagram, Telegram, Line, and many more. We provide a platform where businesses and developers could build their own AI powered chatbots through our natural language processing algorithm, especially to understand Indonesian language.
The first pronoun in English, be it informal or casual, it's only 'I', right? But in Indonesian texting language, you can find 13 types of ways people are expressing the first person pronoun. All the abbreviations, the slangs, and it's just crazy. We collect 3 million messages as an initial training model for our AI to understand the language here.
We do annual subscription in which the customer has to pay some license based on their traffic size, based on the conversations number they are serving every year. Our key focus industries ranging from telecommunication providers, and then we also support customers in financial services. So we have helped over 200 enterprise customers in Indonesia and processed over 2 billion conversations to date.

What sparked your entrepreneurial spirit from such an early age?
Irzan: When I was 8 years old, in elementary school, I was selling caricatures of pictures of my friends, and they could pay me like 500 rupiah and I could use the money as pocket money. And during my middle school years to high school years, I was being drawn to an online game called Ragnarok Online. But I was not only using the game and the internet access I had, but I was thinking how I could make money out of it.
So, those who are playing the games, I built a bot since I was in elementary school. I built a bot for them in which their characters could run and hunt like monsters and then they pay me in exchange for that service. Not only that, there was like this pirated music download services, right? Back then, the original CDs for some bands, music were very expensive. A lot of my friends were asking, 'Hey, Irzan, could you please help me burn the CD? I want to give it to my girlfriend.' So I did that and it became like pocket money when I was in middle to high school, and I was always very happy with it.
At the same time, I have two hobbies which are not really quite normal for kids who are into IT like computers and I'm also into music. So I played bass guitar in a band. I used the money that I made from this side job, so to speak, side hustles to purchase some gears and equipment for my music.
The German Years: Music, Code, and Lessons in Leadership
How did your experience in Germany shape your entrepreneurial mindset?
Irzan: So when I moved to Germany for my bachelor's degree, I got my computer science there, so aside from focusing on my study, I was a professional musician. I was in a band, I was the only Indonesian or Asian kid in a band, the rest were Germans. We toured around Europe, went to Indonesia and I learned a lot being in a band because I learned about digital marketing because I designed the band's MySpace back then, the website. So that's why I did some coding on the HTML and JavaScript design.
And not only that, I talked to a lot of sponsors for our touring. That exactly helped me to shift to where I am today, because when I talk to sponsors, I have to give propositions, it's just the same when you're an entrepreneur, you have to pitch to investors.
I think my first foray into my entrepreneurial journey was building a website called Amply Tweet. So back then, I think it was 2011, and Twitter was very huge at the time. I think they were the largest social media after Facebook. So I found a problem with my band and my other fellow musicians and artists friends that they were struggling to get new followers on Twitter, to build fan base, so to speak.
By building this tool, I made it possible that their fans, when they download their music, their single, their album, they have to tweet and follow the artists and bands. I think I managed to sign up 8 musicians and even 1 from a major label, but I learned a lot because when I was in Germany it was a side hustle. I didn't have enough dedicated time to do that and I was alone, so yeah, I think the lesson learned is, well, you can start as Superman, but if you want to build a business, you've got to be the Justice League.

What drove you to keep pursuing entrepreneurship despite the challenges?
Irzan: I look back to when I was a kid that I loved to make a living from my creation, and I love to make an impact, because my parents always tell me that the best human being and mankind are the ones who can make positive impact to our lives. It resonates in my brain every time, every day, so I took multiple chances to become an entrepreneur. I failed many times, but this time, yeah, I started with Yes Boss in 2015, before it became Kata.AI as it is today.
The Birth and Death of Yes Boss
Tell us about Yes Boss and how it evolved into Kata.ai.
Irzan: Before I started Kata.AI it was called Yes Boss. It's the same company, by the way, but we changed the business, we pivoted from B2C to B2B. When we started Yes Boss, it was a virtual assistant company in which we believe that people in Indonesia, they love to get served, they love services. So through Yes Boss, a customer could chat to an assistant, which is not AI actually. They could ask anything. 'Hey, I want to book a movie for Star Wars for two people in X Cinema for tomorrow,' for example, and our assistant, they use other services to book the tickets and then customers made the payment and they provide the information and the digital tickets.
And then it can do anything, but all in all, we had 50 customer service agents that we employed internally. But from day one, we understood that this wouldn't be scalable and it required AI technology. We did that, but it was not easy because we had to collect the data, clean the data, build the model, test this and that, and then after 1.5 years, we came to a point that, yes, the AI model is there and I think we are at a point that we're very proud of, but at the same time, as a startup, we are constrained with resources, with cash for example, and then with time, with energy, so we had to pick a battle because it was a transition from B2C to B2B, from Yes Boss to Kata.

What was it like to let go of 90% of your staff during the pivot?
Irzan: It was the toughest three months of my life because I was never being an entrepreneur running a business full-time and then I was very upset that I had to let go 90% of my staff back then because maybe they're part of a family. They have to make a living for their family, for their spouse, for their kids, right, for their parents, so I was also in their shoes, right?
We tried our best in order to help them. We helped them to find jobs, we helped them to create a LinkedIn profile, to write a CV for example. So we had to explain why the changes and the business has to survive and we see also AI is the future. So, it's not easy definitely for me and for everyone who was involved there, but we are thankful that we could survive and not only that, we managed to thrive. We grew 2 times from the previous year and I think this requires tight collaboration between all team members and culture is key that glues everything.
Building the Right Team and Culture
What are the key traits you look for when building your team?
Irzan: To have a strong team, there are 3 traits that an entrepreneur should look for. Having the same mission and why. The why has to be clear. You're an organization as a startup and you find people who believe in your idea, your vision. And once the people buy into your why, the rest is limitless.
And then the second one is having this growth mindset, the willingness to learn. As long as the people have this growth mindset, they are willing to learn and they could learn fast.
And the third one is having humility and coachability because we will fail. I made a lot of mistakes and my team will also make mistakes. Having humility is helping us to be coachable, how we can learn from ourselves, from others, and from our superiors and others.
Customer-First Philosophy and Market Opportunity
What's your philosophy on building technology solutions?
Irzan: An entrepreneur shouldn't be falling in love with the technology or the solution, you should fall in love with the problem. Focus on your customers, their pain points and problems, and build your solution around it. So it's not technology first, but your customers first.
When it comes to the problem, it's a market of billions of dollars. Imagine, as your business grows as a consumer business, and you have to add more headcounts. Let's say there were some problems with service or product, it has to be handled by a human. And those people who work in the call centers and customer service contact centers, they are serving a stressful job, because 80% of the questions which are coming to them are the same, within one industry, that's one thing.
The second, the turnover rate is very, very high, that 3 out of 10 people, every year resign from a contact center agency because of the stressfulness in doing the job. And the third one, the cost per call by using human agent and the tools around it, it will cost like $3 US dollars per call.
The Breakthrough Moment
How did you land your first major B2B client?
Irzan: At the time when we started Yes Boss, we always envisioned that AI is the future. So that's what we conveyed to the media, to our investors, and thankfully our investors, they all agreed and they supported our vision.
There's one guy who used our Yes Boss service. He loved the service and at the same time, there's an opportunity coming from the largest consumer goods brand in Indonesia. They wanted to build the first virtual female best friend in partnership with the messaging application Line in Indonesia. So they brought the idea from other markets, from other countries, and were looking for a partner in Indonesia to do that.
I think we were lucky and we met this guy. He was the managing director of Line back then. And we discussed, I want to see our technology and then we ran the POC that we did with our early NLP technology and I think unanimously, the customers and the partner were impressed, and that became our first foray into B2B, building AI powered chatbots, and the result was amazing.
Within a year, our chatbots managed to talk with 2 million users, and not only that, for the business itself, they were happy because out of these 2 million users, 40% of them, or 800,000, they can converse with the chatbot and provide their information so they could re-target for re-marketing, so to speak.

How did that first success lead to more clients?
Irzan: We saw a turning point and it became a snowball effect because it was one of the prominent consumer goods brands and everybody in the B2B scene saw that opportunity. 'Oh, I also wanted that. I also wanted that kind of chatbots.' And yeah, we talked to multiple companies and I think when it comes to B2B, having the social proof and credentials, being trusted by major brands is very important for you to acquire more customers building what we call a brand moat.
Solving the AI Challenge
How do you handle the common problem of chatbots not understanding users?
Irzan: I think I wouldn't deny that there were some challenges, especially with chatbots and it answers, 'Sorry, I don't understand what you're trying to say,' right? What we believe in, yes, the AI algorithm, the NLP has to be strong. You have to understand the colloquial language, the slang languages, and various inquiries, especially the ones that matter to the business. That's one thing.
Second, give a way out for the end users or the consumers, in which we believe there should be human in the loop. So that's why every chatbot we deploy for our customers, they should work hand in hand with an agent in the back office. So if the chatbot for any reason, couldn't be able to serve the customers, it will pass over to the human agent.
So I think that's our idea and from the human agents, we see what are the inquiries that the agents were taking and use that knowledge to train back the chatbot. So, next time there were similar inquiries coming to the chatbot, it already understood without passing over to the human agent.

Scaling Through Partnerships
How did you evolve from custom solutions to a scalable platform?
Irzan: When I found the first customers, it's just like a software house. We had to customize everything. And then we came to the second point that we got this opportunity to work with, I think a major technology consulting firm to serve this telecommunication provider client. At that point, we had to think twice, how we can support the software engineers of this technology consulting company so they can use our product and technology.
We had to build a platform, a developer tool that can be utilized by their software engineers to build an AI powered chatbots using our NLP technology. Kudos to my co-founder, CTO back then, who put a lot of efforts there along with his team back then.
Now, we don't have to customize everything on our own. We can replicate the model and build relationship and partnership with other consulting firms, with other software houses, and that became our go to market model. Working together with these software houses, IT technology consulting firms where they can use and leverage our technology to build AI powered chatbots for their customers.
Because we believe when it comes to B2B, it's not always about the technology, but the relationship matters a lot, and a lot of this relationship has been established for many, many years or even decades, and it's something that you cannot just disrupt as a new player in the town.
What's your approach to customer acquisition in the B2B space?
Irzan: When you try to bring a fresh new technology and innovation to the space, there's a cycle of customer adoption, what you have to find is the innovators or early adopters. Typically they are the first mover, typically they are the market leader, and they always want to stay ahead and have an edge against their competitors.
I believe relationships will go hand in hand with results, because relationship is something that you build socially, that you can nurture it, but results, when you deliver your solution, you have to deliver the promise. Whatever the technology that you're delivering, in my opinion, the best result has the best return on investment. It has to be quantified, especially when you serve B2B customers. How does it impact their bottom line? Whether you managed to save costs, or even you are able to drive new avenue of growth through sales, revenue and transactions.
The Local AI Advantage
What opportunities do you see for local AI companies in the age of global AI giants?
Irzan: I think the opportunity for local AI companies, like in Indonesia, in Southeast Asia as a whole, is to solve hyperlocal problems. So now the algorithm is out there everywhere and it's becoming more accessible, and that's great, right? But the algorithm, it only works when you have hyperlocal data. Data that are not easily accessible by the public on the internet. Data that is not being owned by OpenAI for example, and that's your edge.
It could be in various areas. It could be in agriculture, for example, it could be in supply chain, in healthcare, in financial service. So if these entrepreneurs could leverage AI to solve local problems with hyperlocal data, that's a winning game.
The Future of Conversational Commerce
What's your vision for the future of Kata.ai and conversational AI?
Irzan: We are glad that Kata.ai has been trusted by a lot of corporations in empowering their customer service operations to be more powerful and robust and becoming more productive, so to speak. And the future that we're looking with the rise of generative AI with ChatGPT and others, I believe the future of conversational commerce.
So how we can enable human-like conversations on messaging apps to help consumers to interact with businesses, to pay for services, to transact, to buy the products, to purchase, and make it easy and seamless. So, I think that's the future and the focus that we'll be heading this year and moving forward.
Well, I think my dream is that I want Kata.AI to create a long-lasting impact. Even I'm not part of a company anymore, maybe I'm not here anymore, but I wish the impact will still last on how we can deliver impact with AI to people and improving their happiness, their productivity and create the best customer experience.
