Summary

Pauline built AI Korea, an AI-powered home renovation SaaS generating $8,000/month MRR while working full-time at IBM. The episode explores her framework for finding validated ideas, building MVPs quickly, finding customers where they congregate online, and reducing churn through pricing strategy and product improvements.

Insights
  • Successful indie hackers validate ideas by getting them in front of real customers quickly rather than perfecting products in isolation before launch
  • Marketing channel effectiveness depends on where target customers naturally congregate (LinkedIn for B2B professionals, Twitter for developers, Facebook for real estate agents)
  • Offering both subscription and one-time payment options builds customer trust and reduces perceived lock-in, directly impacting retention
  • Adding yearly subscription plans significantly reduces churn by increasing customer commitment and engagement with the product
  • Solopreneurs can build six-figure revenue businesses while maintaining full-time employment by working nights and weekends, then transitioning to full-time once validated

How did this girl build a $100,000 per year AI app while working a full-time job? Well, it's because of how she's growing it. To find customers online, you have to think about where your clients are. Pauline spent her first few years as a part-time indie hacker, building side projects but not seeing much success. Then, after several failures, she found a winning idea in one of the hottest yet most saturated industries right now, AI apps. But it turns out there's still plenty more opportunity than you might think. I think the biggest opportunity might be to... I spent over an hour talking to Pauline about her AI business and what I really tried to figure out was how she was able to succeed in such a crowded market. Good news is she shares everything. How to find good ideas, her framework for marketing and AI tool, and some unique ways to reduce churn for your users. Alright, let's get into it. I'm Pat Walls and this is Starter Story. Welcome Pauline. Thank you for coming on. It's great to have you. Tell me about who you are and the business you built. Hi, I'm Pauline and I built AI Korea. It's a service to renovate home in seconds thanks to AI. You just upload a picture to the service, you select a style, and a few seconds later, you see your kitchen in a very modern or Scandinavian way. AI Korea has more than 8,000 users right now. It makes around 8,000 euros every month. On the business model, when someone sign up to the SaaS, they have three trials and then they are required to pay to continue to use the service. Pricing models is a one-time payment with a certain number of photos and you also have a monthly payment with some extra features. So you built this $100,000 per year app while you had a full-time job. Tell me more about that. I learned to call in engineering school after college. I joined IBM and after this, I kind of switched and I said, okay, that essence is not what I want to do all my life. What I want to do all my life is entrepreneurship. But I wasn't ready to make a big jump of becoming a ninja hacker because I needed money as well. When I worked at IBM, I had only the night and weekends. I stopped IBM in June, two months ago. Having is really different when you are working on a day job or you are in the hacking full-time. Wow, that's amazing. So your side project allowed you to quit your nine to five and now you're a full-time founder. What I want to know is how do you come up with ideas? I think I usually find ideas when I encounter some problems, either me or friends. When it's friends, like for a career, I ask a lot of questions. Really, you have this problem, but when, how frequently you have this problem, I really think, am I able to do better? Am I able to build something around it? Am I able to monetize it and to find clients? That's really important creation. If the answer is yes to everything, I start on working on it. Okay, cool. So we talked about ideas, we talked about problems. My question is, once you find that idea, how do you validate that it's an idea worth building and that it can make money? I start some marketing or I start to communicate on my product. If I have some client kind of quickly, then I say, okay, maybe there is something that I could do around it. I start AI-craw, I build an MVP and then I show it to a few real estate agents that I found online or in personal network. For people that say, that's awesome, I want to buy it now. And they actually paid for this. So that was the validation. Okay, so get your MVP out there, see if people are interested. That is the way to build. But can you tell me a little bit more about what it looks like to actually create that MVP? In my opinion, the sooner you ship the better, because sometimes you imagine your client wants this, but what they actually want is this. So it's really hard to imagine what your clients want if you don't have clients. When you start, don't expect everything to be perfect. AI-craya, for instance, MVP was a simple feature, bad quality. It was done maybe in a month, but then it's a year of work to improve it. Pauline is the perfect example of how one person can turn a simple idea into thousands of dollars even while working a full-time job. And her blueprint was simple. She found an idea, she built a really simple MVP, and then she validated that it could actually make money by getting it in front of her actual customers. That final step is where almost everyone goes wrong. And this is why we built the Starter Story Academy. It's a five-week program where you'll come up with an idea, you'll build something simple, and then you'll spend all your time focused on validation and if this thing can actually make money. Inside the Academy is a clear and actionable track you can follow with milestones, deadlines, and it's all gamified to get you to take action and work on the things that matter. This is not just another course. This is the turning point in your journey. Imagine what you could accomplish in five weeks if you simply worked on the right things. What's even cooler is that you'll do it inside our community of thousands of successful founders working on similar problems and building online businesses that will change their lives. So if you're serious about actually doing this thing and you're ready to take action, I'm going to leave a link in the description where you can learn more. Okay, so we build the MVP. How do we go and actually find customers? To find customers online, you have to think about where your clients are. You have many social media like for instance Facebook or LinkedIn are ready to go through them and just type in the search bar like you are looking for real estate agent, type it in LinkedIn. Let's see if you can find some communities on it. For instance, AICREA, my best marketing channel is probably Facebook and physical event. Maybe because real estate agent, it's really an activity of human. But for next GS directory, my main marketing channel is Twitter because I have big audience there and my audience is mainly developers or people who want to do handy hacking. So this product really is a fit with them. Okay, so the best places to market our products are where our customers hang out, right? But what if we want to accelerate that growth at the very beginning? What are specifically some good places to launch apps as a solopreneur? Now I prefer to launch on productant in order to get a backlink for SEO because it's a very good backlink. But visibility is less good than it used to be. So I'm launching on productant and also on Twitter because I have a big audience there. Actually I will use my newsletter as well. I didn't launch next GS directory on Facebook, but I launched a Crayon Facebook. All right, so now you got people interested in the product. The next thing I go to is how to monetize it. How do you determine plans and overall pricing strategy for an app like yours? If you sell for low price, you have an image of being a low cost. You don't have the same client by selling low cost to high cost and also by selling higher price, you might have less clients, but it's less support as well. So you have to also think about how do you want to be perceived and how much support are you able to deliver as well? Okay, let's talk about business models. Do you prefer a recurring subscription or one time payment? I'd love to hear your thoughts on this. I like to offer both subscription and one time payment because some people really don't like subscription. I had a few subscriptions in many services and it was a nightmare to cancel. I don't like this kind of retention. My button is very clear. When you subscribe, you have it canceled and it's really easy. I think it's really important to earn trust from your customer as well. All right, I love it. Besides building trust with customers, are there any other hacks to reduce churn or just increase revenue in general? Last year I had a high churn and I really reduced it drastically by adding yearly plan. It sounds stupid, but now they are engaged for a year, so they will use the service better. The second one is I did a free trial. So now people can try before subscribing. They are able to see if the service fits their needs. And the third point is I really improve the service. Like the quality, it's much better than last year. It feels really like a photo. Okay, and what's the tech stack you use? How do you stay up to date with AI and run your business profitably? I use a Discord every day to talk with my co-founder and people working with us. I use Crisp for the support clients that you can chat with us through the chat window. I use Twitter a lot to share my journey, to share what's new on AI Korea, LinkedIn as well. I'm going to use it. I use also Buffer to schedule my tweets, VHIVE to send my newsletters, but I'm still on the free trial for this one. Breville for the marketing automation of emails. The database authentication is super base, but this is more like a technical tool, I guess. I mainly use NECJS as a language, but for AI models I use Python. I think my business costs around 3,000 or 4,000 euros to run each month, but it includes the servers. It includes some marketing, like we run ads sometimes. Also it could be the cost of freelancer and going to personal events. I could cut some costs, but for the moment I'm not trying to save the most money I'm trying to invest in order to grow the business. Okay. Tell me about the biggest opportunities in the AI space right now. I think the biggest opportunities might be to insert AI in an existing product. You receive email every day. What if you have an AI that can help you to answer to your email? This is a service plugged in another one, and that's something that could do, because biggest opportunities I think is service. Got it. Okay. Since the space is heavily dominated by dudes, how does it feel for you to be a successful girl indie hacker? Yeah, I don't know why, but girls are not visible. They are not doing much indie hacking. So please don't retain yourself if you are a girl to think, oh, but there is only men. It's not for me. No, it's for you as well. If you enjoy coding, if you enjoy SAS, please do it. I think it's really important also if you are a girl to be visible, because you will inspire others to do the same. Don't hide yourself or return yourself from building if it's something that you want to try. All right. Last question that we always ask all founders when we interview them. If you could stand on a younger Pauline's shoulder and give her some advice, maybe when you were just starting out, what would you tell her? Okay. If you want to start in the hacking, please don't wait for the perfect product to launch. Just start to do something because it's highly likely that your first product will fail. I don't know any entrepreneur who achieved success at the first time. So you will learn a lot during the journey. So please chip very fast when you have an MVP and ask for a lot of feedbacks and be consistent. And also, I think make connection with people who are doing NDRK. We exchange best practices, we exchange tips, we exchange some things that didn't work in order to improve us. And my biggest lesson was, I think it was to invest in yourself. You are the common point of every project that you build. And think about how you can reach your customers. And think like, okay, you could do some Reddit message or Discord message or DM people. I mean, think about really how you could build genuine connection to your customers. Thank you for coming on the Starter Story channel, sharing everything you know and inspiring millions of people to start their own business. See ya. Yo, guys, I really hope you enjoyed the video and got some good nuggets with Pauline. I think the business that she built is really impressive. And I really like the way that she went about building it, talking to customers, and actually building something that people needed. But I want to say something real quick. At the end of the day, the purpose of this video is to show you that regular people like Pauline change their lives by building a business. But watching this video is not going to magically give you a business that changes your life. You need to go find an idea, you need to take action, and you need to work relentlessly to validate it and see if it's something that can actually work. While learning is important, action is the thing that's actually going to get you your dream outcome. So, if you feel like you're still struggling on this, maybe some analysis paralysis, not exactly sure what to work on, then I highly recommend checking out the Starter Story Academy. Again, it's not for everyone. It's only if you're really serious about actually doing this thing, actually building a business while you have a full-time job that could change your life. Inside the Academy, you'll get an actionable blueprint to follow every day. It will give you the right habits, but most importantly, it will put you on the path on how to find an idea, how to validate it's an idea that can actually make money, and how to actually build that idea and bring it to life. Just head to the first link in the description if you want to learn more. Much love, and I'll see you guys in the next one. Peace.
