With limited launch resources and to increase speed to market, which pillar is the least impactful?

I really don't know. I've been struggling with this for the past couple of days as I've been building amihot. The designs in Figma are immaculate, but I'm just not a developer, so the UI/UX suffers when I go to execute. And I sure as heck haven't been doing enough marketing for it. But I'd probably say that dev and design are actually inseparable.
