It would actually be better if the community were able to compile a good list of specific people within each company for David to contact rather than just throwing out emails to companies from users here. I believe that companies would be more likely to respond if they heard directly from David or someone associated with Iota along with a solid introduction/pitch on Iota. Obviously we are early stage, but the Azure partnership is a great selling point, and I think it will lead to more corporate partnerships.
The IOTA contact person in the email letter is David. This is just an introductory letter. If the companies want to know more, based on the letter they are supposed to contact David. You point is good and I would like to participate if you can form a plan based on your idea. We need multiple channels to do the promotion and let IoT community know IOTA.
