What's the story behind your product?

Cosmos Video's answer

Cosmos was founded in 2020 by Karan Baweja and Rahul Goyal to solve the fundamental problems of remote work: isolation, meeting fatigue, and lost team culture. They saw colleagues struggling with "working remotely on your own is lonely and isolating" and recognised that "inviting people to meetings for quick collaboration is painful."

Instead of another video conferencing tool, create a virtual office that feels alive โ€“ where you can see colleagues at their desks, walk over for quick chats, and maintain the spontaneous interactions that spark creativity and build culture. Today, Cosmos serves thousands of users across creative studios, agencies, and educational institutions.

Another resource that is good is http://csbin.io/ which is a codesmith platform.

  • What do you think about interactive courses like Scrimba? Are there any that you like or would recommend?
    Hi everyone! I'm in the very early stages of creating an interactive course and I would like to hear your thoughts on them. So far I've come across Scrimba and Jad Joubran's learn X series of sites (learnjavascript.online, learnhtmlcss.online, etc...). Has anyone completed any of them? Any there any others that you really like or would recommend? Source: about 3 years ago
  • No prior coding experience, what should I be doing and what to look for in a bootcamp?
    Learnprogramming.online and learnjavascript.online (I haven't really looked at these too deeply yet, but someone just shared them with me and they look really cool!). Source: about 3 years ago
  • What is something you learned while learning javascript that you wish you had known from the start?
    I am learning to code in Javascript using https://learnjavascript.online/ but am finding it a lonely experience. Hoping to jump in and learn with others as I go. Hope this question may help get things going. Source: about 3 years ago
