Job Description


What does life mean to you? What motivates you? What makes you happy?

We wake up every day with one purpose; to make the most out of life by sharing it with those who make it special. Happiness is attained when one’s thoughts, words and actions are aligned. And we want to see that people is happy. Life is a gift that must be enjoyed every day.

What if you could meet all those people who share the same beliefs, interests and want to live the same experiences you do? People who’s down for trying the same things you want to try. At the end, life is about people right? If the people you surround yourself with don’t quite fulfill you, keep looking and don’t settle.

What is your dream? What do you want to achieve in your life? What would you like to do today? What are you thinking right now?

The ideal candidate would be someone who truly believes in and loves the product and shares our passion for how we are going to change the way people connects.

From this point on, we will continue to iterate the product as long as it is necessary, until we feel very comfortable with the end result (aka. users love it) and are ready to scale it.
