That's awesome! Very inspiring Out of curiosity, I see that the $16 pack gets you your own logo and branding. Is that kind of vanity something people actually ask for? Always sound weird to me :)
Regarding adding a custom logo, that's mostly a need of professionals in larger businesses (think project managers at Fortune 500 companies), so having that on the top paid plan encourages those type of users to upgrade to that plan vs the cheaper one.
