Launch websites with enterprise needs at startup speeds.

I’ve been following all the vibe-coding hype lately and realized something — building is faster than ever. But figuring out what’s actually worth building (not just another “cool project”) still takes forever. That’s why I created Zeros By Kai → https://www.zerosbykai.com/ It’s a free weekly email that surfaces 10 startup opportunities pulled from real conversations happening across the internet. Instead of trend-chasing or AI-generated fluff, it focuses on recurring frustrations and unmet needs people are actively talking about on platforms like Reddit and X. If you’re stuck in “what should I build next?” mode, this might help. If you end up building something from the list, Kai would like to know :P
