business – Presenting yourself as “We” vs “I” as the only person in your startup

As a SaaS startup owner and only person in your business, when you interact with customers on your website/forums, is it advisable to refer to yourself as “We” instead of “I” despite being only one person? The reason I am thinking about this is, if I use “I” customers could lose trust in my abilities as a single person to care for their concerns. So I personally would like to use “We” in order to appear more competent and able, but obviously that could be regarded as dishonest/deceiving.
