TL;DR Build Fast, Sell Faster
You've probably seen tons of stories online of successful devs who build a SaaS app and starting brining in the money.
Well, we've got another one for you.
And we're not sharing this story with you to make you feel bad, but rather to inspire you and tell you about the dev tools that made it all possible.
First of all, depending on who you are $20,000 may seem like a small amount of money, considering apps are often valued for millions of dollars in the tech world. But for others, $20k can be life changing.
, a tech lead by day, and a tinkerer and indiehacker by night who built and sold , Kaloyan was diving into the world of ", were very expensive.
Seeing how expensive these tools were, Kaloyan decided to take matters into his own hands, building his own tool in just a month.
Initially, his tool automatically created and uploaded shorts, but after some time, when his channel didn’t pick up, he stopped the project. Fast forward to a year later, and YouTube's algorithm brought similar content back into his feed, reigniting his drive.
This time, Kaloyan took it further by transforming his tool into a SaaS product:

All about NuloApp
NuloApp is an AI-assisted tool designed to make video content creation simpler by converting long-form videos into short clips that have the highest chance to capture audience’s attention.
It automatically resizes and captions content from horizontal (landscape) to vertical (portrait) for platforms like YouTube Shorts, Instagram Reels, and TikTok, helping creators push content faster.
Payment integration: Stripe
Other tools: OpenCV, FastAPI, Meta's llama, OpenAI's Whisper, LangChain
Database: PostgreSQL
Programatically Editing Videos
The real genius behind NuloApp is the way that Kaloyan combined a number of tools to programatically edit the longer form videos and podcasts, into short, engaging clips for social media.
First of all,
In order to programtically get the correct clips to be extracted, AI tools like Meta's were also used. Whisper allowed for fast speech-to-text transcription, which could then be passed on the llama in order to find the segments worth extracting.
Putting these tools together and accessible via a standalone API was the final step in this process. But this really clever combination of tools was just one part of puzzle. The next problem to solve was how to deliver it all as a SaaS app that users could pay for?
Why Wasp?
When Kaloyan decided to relaunch his tool as a SaaS product, he didn’t have time to spare. He needed a framework that would allow him to build and deploy quickly. That’s where , with well-structured documentation, alongside its responsive Discord support, made it the ideal choice.
The Impact of Wasp on Development
Kaloyan was particularly impressed with how Wasp simplified complex tasks that would normally take much longer to implement. From setting up Google logins and dark mode switches to creating hourly jobs, the development process was smoother than expected. “Everything from enabling Google logins to creating hourly jobs I badly needed was way too easy to set up”.
If you're considering Wasp, Kaloyan’s advice is clear: Wasp is easy to get started with and flexible enough to build what you need without adding unnecessary complexity. For Kaloyan, Wasp was ideal because it handled the boilerplate while still giving him the freedom to customize as required. "The documentation is also solid, which definitely helps when you're moving quickly.”
Auth and Stripe Integration Made Easy
One of Kaloyan’s least favorite tasks as a developer is building out authentication systems, and he found that even implementing third-party libraries could be frustrating. Fortunately, with the primary goal of gathering feedback from potential buyers about what features or metrics they value most in a SaaS product.
To his surprise, within the first day of listing, he received multiple offers. After a brief meeting with one interested buyer, they quickly agreed on a $20k deal, validating the product's value and market potential.

if you've got questions, are looking for inspiration, or want to share what you're building. Who knows, maybe you and your app will be featured in a future blog post just like this one?
Thanks, and see you next week.
