Are there any prominent examples of side-projects that were quickly sold due to high growth in the first few months after launch?
Either to a VC, competitor, entrepreneur etc.
Kind of like a 'ready-made' startup for someone to build on.
I'm not sure if this counts, but Indie Hackers itself was founded in 2016 and acquired by Stripe in 2017 (I think it was less than a year later, but not sure). https://www.indiehackers.com/blog/acquired-by-stripe
