How I Started a Tool to
Transform Images and Screenshots

Hi! Who are you and what business did you start?

Hello! My name’s Viet-Hung Nguyen. I’m the creator of Limus – a tool to transform your images/screenshots. The word “Limus” in Latin roughly means “skew”…at least that’s what Google translate told me. The reason I chose that name is that, Limus is a tool that will give the image a skewed, 3D look and you can use the resulting image to showcase your app, products on websites, blogs etc.

What is your personal story and how did you come up with the idea?

I started launching apps back in 2018. I was just a Software Engineering student who had a lot of ideas and wanted to show the world what he had worked on. One day in 2019, I was working on the landing page for one of my next products. I discovered the landing page that used a 3D transform on their screenshots to showcase their product.

I really loved the professional look of the screenshot and therefore, I started to learn how to apply those transformations on the image using Photoshop. It works but the process of starting Photoshop and loading the image takes a lot of time, thus, I created Limus to help solve that problem.

“I learnt that not all great products have to be hard to create, just a simple tool that solves the right problem for the users is enough.”

What challenges did you face when creating your product/service?

One of the challenges that I faced was the lack of time to work on the service. As I have mentioned before, this app is a tool created to serve other products that I am working on. Thus, I find it hard to create time to work on this project.

I also faced a few problems on image quality of the output and UX design to help the users to understand how to use my app easier. But overall, the app is relatively not very technically demanding. After working on the app, I learnt that not all great products have to be hard to create, just a simple tool that solve the right problem for the users is enough.

Who is your target market?

My target market are graphic designers, marketers, and even solo creators like me who need to create a professional look for their screenshots/images to showcase their product better. Anyone who wants a professional look for their images can use this app. I can definitely see people using it for their website, design and even blog posts.

How do you market your business and which approaches have been the most successful?

I have tried to advertise the app on Product Hunt, Twitter and Hacker News but Product Hunt seems to be the most efficient way to attract new users. After that Limus has been featured on some foreign news website which created a spike in traffic that is almost as high as that on launch day.

” If your product can solve your problem, it can solve the same problem for other people too.”

Since you launched, what has worked in not only attracting but retaining customers?

I think the idea of the product is what keeps the customer coming back. At the moment, the majority of visitors are new visitors, only around 9.3% are returning visitors. I have been working on improving the app UX to help users create a resulting image faster and I believe time-saving is the major factor to retaining users.


What kind of culture exists in your company, and how did you establish it?

I’m a solo creator working on multiple products at the same time, therefore, I always try to keep the product running on its own as much as possible since I can’t make time to fix errors on all of the products that I launched, especially when I also have a day job too.

What software, services or tools do you use within your business?

I use Netlify to host the app and deploy the app from Github. Other than that, the app is just a static website developed with React.js.

What are the most important lessons have you learned on your business journey?

The most valuable lessons that I learnt are:

  • A great product does not have to be complicated.
  • Failure is part of the process
  • If your product can solve your problem, it can solve the same problem for other people too.

In the past, I have created many products but ended up not launching them just because I thought no one would be interested in it. However, after launching a few products, I realized how many people have the exact problem as me and my products are as valuable to them as they are to me.

Some of my products also failed after launching, but I learnt from failure more than from success. Thus, every time I fail, it’s an increase in success rate since I know what I have done wrong.

What is your favourite aspect of being an entrepreneur?

You can be your own boss, deciding how your product is going to look and what kind of direction the product should lean toward. While I do enjoy working as a software engineer for a company, having the kind of freedom in making decisions is what I really enjoy when I become an entrepreneur.


What is your LEAST favourite aspect of being an entrepreneur?

As a solo creator, it’s always hard to research everything from pricing your product, market research to technology stacks. But I think if you can find a person who shares the same interest and vision, the process of being a creator/entrepreneur will be much more enjoyable.

What books, podcasts or other resources have inspired and influenced your business journey?

Hacker News, Indie Hackers and Product Hunt are the resources that keep inspiring me and giving me new ideas to try out. Many tips that I learnt on launching products are from the Medium blog of Product Hunt and other creators who succeeded with their launch.

Where do you see your business 2-3 years from now?

In the future, I picture the product will not stop at just being a web app but going to integrate to other tools such as Figma. I’ll also try to create an income from the app by having some premium features.
