You definitely shouldn't worry about your supplier(s) taking your ideas or designs! Pietra works very hard to vet and train our partnered suppliers to ensure the highest level of professionalism.
That being said, if you would like any added layer of protection, you are more than welcome to submit NDAs to any supplier(s) that you work with. All of our suppliers are open to working with you to make sure you feel that all precautions are being addressed and handled with care.
For any legal advice, we recommend seeking counsel outside of Pietra.
