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](https://runacap.com/), recently shared a list of the [top trending OS startups](https://runacap.com/ross-index/q4-2023/) from Q4-2023. 👇

With this in mind, let's explore the 10 trending YC-backed open-source companies (and those you should consider contributing to). 🧑‍💻👇
