We have been using it for several months and it helped shaping our remote culture, by enabling a more open and less formal way of communication. We absolutely loved it, which is also (for full disclosure) why I have invested in the company, even if a small amount :)
We have been using noknok for a few months now. a team of 15 working from home, and from the office (but sometimes different floors). this product is very intuitive and easy to use, and allows fast seamless ongoing interactions between team members. its just much better than combining Zoom + whatsapp/sms + emails + phone calls
