Yes, it is a milestone for me :)
It's been a hell of a journey. I am super happy to say that there are over 50 organizations using Spike. Some stats -
I am still happy with the progress so far. My goal was to really get only 1 or 2 happy customers with whom I can engage in a constant feedback loop.
I have a list of 20 features to be built but users asked for something completely different so I am building that now.
Key is to not be deterrent and going on.
