Do you tell your customers you're a solo founder?

I've run my company in Japan for 22 years, mostly on my own. And in Japan, I sometimes deliberately didn't mention that.

My reasoning was:

・Customers there want to pay for a proper product

・Given the choice, I think many would pick something built by a team of 10, even at 20% more, over a product

from one person who sounds stretched thin

・So saying "it's just me" felt like it would cost trust

Now that I've started sharing my work in English, I've decided to do the opposite and say it openly. A few people here told me that people buy from people, and that stuck with me.

Do you tell your customers you're a solo founder? Has it ever helped you, or hurt you?
