Hi rivet,
interesting point - I guess because some of us didn’t know these competitors? 
Another one is that imho with photoscan you get more for the buck, especially with the basic version, so it’s just more well known with enthusiasts and freelancers who don’t use it exclusively an therefore can’t afford the ones you mentioned.
Another one is that I think many people who got involved here are looking for alternative programmers or rather specialised software. I personally am not a fan of huge companies like Autodesk and Bentley (which excludes one of your examples for me) because there is almost nothing you can do as a small customer, whereas here you chat with the guys more or less directly.
Btw, the Israelian one you’re talking about is Datumate, right?
Wishgranter,
which one are you talking about? All of them? 
Speed is very important, but even more so is memory consumption in which your app excells over Photoscan, too, as far as I can tell. How would you judge the diference to the above mentioned competitors?
Their hardware specs seem rather modest.
Back to the topic:
What I find very nifty are some pricing options, namely the monthly one - have you guys considered that at all?
