Hey friends, 👋
In this week's article, we're excited to unveil 10 trending YC companies to look out for (and ones you should consider contributing to)!
Launched in March 2005, Y Combinator (YC) is inarguably the most successful pre-seed fund in the world.
In its nearly 20-year run, it has backed legendary companies such as Gitlab, Airbnb, Stripe, Reddit, Twitch, and more. 🚀
With open-source continuing to be a desirable investment sector, Runa Capital, recently shared a list of the top trending OS startups from Q4-2023. 👇
Interestingly, and perhaps unsurprisingly, a non-trivial amount of those were YC-backed startups.
With this in mind, let's explore the 10 trending YC-backed open-source companies (and those you should consider contributing to). 🧑💻👇

This is a really nice list. Some of them might be hiring. Keep checking the Hacker News for who is hiring post.
Nice work @fernandezbaptiste
I appreciate the comment, Saurabh - and yes, good stuff on the hiring point! 🙏
Thanks for the mention! Appreciate all the cool projects mentioned here :)
Wow, I didn't know Zagreb was such a tech hub 😄
This comment is spot on! 👏
It seems like this is still a relatively unknown fact, but the trend will soon catch on. Maybe what is missing is that Zagreb's native startups (including, hopefully, the ones above) need to reach their next growth stage. Once achieved, the wider public will recognise Zagreb as a real tech epicentre.
Great list!
Thanks a lot Uli!
