Its refreshing to see a startup doing well and not feeling the need to force a subscription on people. I get that SaaS can be a good business model (great, even). On the other hand, I think subscription fatigue is real and you should think hard about your pricing. Dawson is making $15K/month on ONE TIME fees–and fees that are lower than a lot of monthly SaaS plans. I want to see more of this.
It's hard to see a subscription model for logo designs though. It's not like you need a new logo each month.

not exactly just logos but people seem to try and SaaSify everything.
