Hey friends 👋

In today's article, we will dive into the open-source startups YC has invested in 2024.

If you have never heard of YC (though I'm sure you have 😉), here is some background context. 👇

---

Launched in March 2005, Y Combinator (YC) is arguably the most successful pre-seed fund in the world. In its 19 year run, it has backed legendary companies such as _Gitlab, Airbnb, Stripe, Reddit, Twitch, Instacart and more_.

Since its inception, **the accelerator program has backed over 4,000 companies!**

With over 150+ investments in open-source startups, **Y Combinator has always been a big proponent of the open-source space**. You can find all the repositories of OS startups they have ever invested in [here](https://www.ycombinator.com/companies/industry/open-source).

More recently, YC released their _2024 Requests for Startups_ , a post describing the various industries/ideas YC is interested in backing. 

In their post, they invite founders to consider building commercial open-source companies as "_it is a great way for startups to become mature and sell to enterprises a lot sooner."_ 🧑‍💻


This article will thus reveal the open-source start-ups YC invested in the Winter-2024 batch (_aka Jan-2024 till now_). 

✍️ **Note**: Where applicable, we have added a _Contributor's Corner._ This section contains some useful stats for readers who may be interested in contributing to these repos. :slightly_smiling_face:
