Hi Marco,
Looking good so far, but you guys can do better very easily.
First, improve your image. When I first stumbled upon Kraftwurx I did a search to find out how legitimate Kraftwurx might be. What I saw didn't impress me at all and I was reluctant to order cuz of this. But when I saw that Kraftwurx was in the stages of beta development, I then decided to take a chance. How to fix this. Upload some good videos of your facility and add some professionalism in this way. I now know that not all processes are done in house, so this needs to be made clear so that when someone sees the list of materials they don't think that all of those processes are done on site. When I first saw this list of materials being offered, along with the videos and images I found online of your facilities, I thought that perhaps this was just wishful thinking on the part of Kraftwurx and so that didn't make you look good.
Also, some of the processes that are being offered are not currently competitive with other 3D printing services. I'm sure you guys are aware of this, but you should tell people why this is for each material. Sterling silver for example, you guys are the only ones offering 0.1 mm resolution whereas everyone else is offering 0.3 mm resolution. Ergo, that's I payed nearly twice the price as what everyone else is offering. And along this line too, the description for each material needs to be improved.
You need to provide more communication as to what's happening with an order. If you look in my account inbox you can see an issue about this being discussed, which I'm sure will be resolved by this upcoming Monday. One of your competitors is very good at this and you guys should look into how they are doing it, they even provide an RSS feed to customers with real time updates about orders. PM me, if you're not sure what competitor I'm referring to.
What's good about Kraftwurx? The business model is BRILLIANT! You will definitely make a fortune with this!
The uploading, setting up an account, setting up a store and the general operation of the site is working and looking very good in my opinion.
Keep up the great work!
