What would make you try a product from a solo founder?

I've been thinking about this while getting closer to launching my own product.

There are so many new products launching every day that simply saying “I built this” doesn't really give someone a reason to try it.

So when you discover a product built by a solo founder or a very small team then what actually makes you stop scrolling and to look what they really built?

Is it the problem they're solving, demo, story behind the product, social proof, recommendations from others or something else?

And if you're building something yourself, what are you doing to earn that first bit of trust before launch?
