That is not true, at least not for all types of products.
I make an e-paper calendar. There is nothing like it on the market. Regularly, I have customers who say "wow, I have been looking for this for years!".
Some of these customers have googled for such a product before mine existed, and found that none exists.
Without marketing, how would these people learn that the product they've been looking for does now exist?
How do you expect to face competition from general-purpose, high-resolution E-Ink displays appearing on the market now? They are getting to the point where it would be within the ability of an average computer hobbyist to mount one on their wall along with one of the many 'HDMI stick' computers.
Your product looks very polished already, and is considerably cheaper than such general purpose displays right now. However, the E-Ink display market is (finally) becoming mainstream, which makes me wonder where you'll go from here.
No problem if your response would be too sensitive to share in public; good luck with your business in any case!
