Ask HN: Where to invest $5K?
Is it possible to start some startup with this money? If someone have some success stories to share with us it would be more than welcome.
I would recommend you keep your eyes open for a problem, then build a solution to address said issue. Focus your resources on growing your user base and then your revenue slowly. Look into the term "bootstrapping" for businesses funded this way.
Personally, I'd sit tight on it until you get around $15,000-$25,000.
When people say "ramen profitable" it generally means paying you enough to live on cheaply so you have all your time to work on the business.
