TikTok - you don't need followers to get views. It's not easy, especially if you've never used the platform before. But for B2C it's one of the best platforms.
Do founder stories ("I built this") or demos ("here's this SaaS you'll like"). They get less views than memes or tangential videos. But conversion is much higher and you'll get replies from people who liked it or tried it out. So you can send them a message to ask for feedback.
I liked X for a similar reason; when I ran ads, customers would comment and you could directly hear what they thought about the product or even just the ad. The big issue however was I usually couldn't DM them due to changes in how X DM's work
