5 days ago, got a refund request due to slow loading issues.
Instead of just processing it, I replied: "Before the refund, can we chat? I want to understand what's wrong. Might even find a quick fix for you."
We talked. Understood the problem. Fixed it.
Customer stayed. 💪

30 days ago, vexly.app got its first paying user.
Today we're at 10.
It's not about the size of the number, it's about the validation. People are paying for what we built.
Now back to making it even better.

Day 2 of building an app to track my subscriptions.
I'm currently working on the landing page. I think it is the most important because it determines whether the customer will buy your product.

Day 1 of building an app to track my subscriptions. I have a lot of subscriptions that I need to manage, and I sometimes just forget that they exist. Hopefully, this can solve my problem.

My SaaS reached 20 paid users after 1 month! 🎉
What I learned
1/ Marketing is crucial. Spent 1-2h daily on social media:
• Daily TikTok posts (memes + product videos)
• Reddit: Focus on value, not promotion
Average: 200-300 views/post

I think sharing the experiences you gained while building a product is also a great marketing strategy. See how much traffic I got today after sharing how I got my beta users on Reddit.

Getting testimonials for your SaaS matters. They show that your product works and that real people use it.
I spent a lot of time sending DMs and emails, asking users for feedback.
It took effort, but it was worth it.
