Weekends are for side projects!

Share what you're going to be building or an idea you're kicking around.

I ve been building apps for 3 years little to no success. Recently, I launched my first successful startup Yadaphone. It lets people and teams make cheap international calls from the browser. In under 3 months, it reached 1500 users, 7 enterprise customers, and brought in $15,000 in revenue.

Before that, I thought I had a clear idea of how indie hacking works: you build something, launch it, get users, and continue doing the same stuff as at the start, but on a larger scale (and get $$$). That couldn t be further from the truth. Here are the top problems I wish someone had warned me about.

YC published a list of themes they want to invest in:

1. Full-stack AI Companies

2. More Design Founders

3. Voice AI

4. AI for Scientific Advancement

5. AI Personal Assistant

6. Healthcare AI

7. AI Personal Tutor for Everyone

8. Software Tools To Make Robots

9. The Future of Education

10. AI Residential Security

11. Internal Agent Builder

12. AI Research Labs

13. AI Voice Assistants for Email

14. AI for Personal Finance

Of course there are many projects and startups that launched on Product Hunt in each of these categories.
