Initial traction is about more than just a tidy number like $1M+ ARR. Your growth rate also needs to surpass a certain hurdle rate. At a minimum, this may be six percent a month (2x annual growth), but ideally it's more like ten to fifteen percent a month (3-5x annual growth). You also have to acquiring the majority of your customers through a zero-cost marketing channel or else it's too expensive to scale.
However, if you can get to $1M+ ARR fast enough and cheap enough, you probably have an interesting opportunity to scale.
