One of your problems: The first time I heard of your product was the shut down notice. Just had to ask "what is Touca?"
Having said that, our v2 launch last month was on the front page for about a day: https://news.ycombinator.com/item?id=34959276 ...but it was too little too late.
I wanted a name that is easy to type on the command-line (since that's the interface for many users), easy to pronounce, and somewhat meaningless in English. Touca was the best I could think of. :)
