Show HN: I accidentally helped coaches increase their revenue by 40%

Hacker News - Wed, 04/09/2025 - 10:57am

Hello everyone, Madjid here.

Since I was a teenager, there have been two things I've loved most, engineering and playing the piano. Eventually, I became a software engineer. After graduating, I realized a 9-to-5 wasn’t for me. The only solution ? Building my own software. But I had no idea what to create or who to build it for.

After months of struggling ( because every good story needs some ), I saw a quote : “ If you want to build software that helps, start with a problem you’ve faced. ”

This reminded me of my university days teaching piano. Organizing lessons, scheduling, and balancing studies was a hassle, and I never found a tool to simplify it.

I researched and was surprised that even in 2025, coaches still relied on tools like Calendly and Linktree, which weren’t ideal. That’s when I decided to build a tool to help coaches save time, eliminating manual scheduling, endless messaging, and payment hassles.

I took it seriously because I knew it was a real problem. After three months of dedication, I finally launched it :

- A custom portfolio to showcase classes - Booking system for one-time & recurring classes - Accept payments from students at booking - Manage booking with user friendly interface - Overview of your key metrics - E-mail notifications for new bookings & cancellations

Now for the happy ending After launching the beta, we gained few satisfied users. Surprisingly, they all saw increased bookings, even though the tool was just a website builder and booking system.

What one of our beta users sent me : “ After setting up my website and sharing it on social media, I instantly started getting more bookings, as if people didn’t know I offered this coaching service before. ”

After researching, I realized coaches mainly shared their portfolios on social media. Many potential clients avoided booking simply because calling felt like a hassle. It sounds odd, but it's real.

Simply because it was easier to do online, they decided to book.
