At which point do you know product market fit? How many users would you say? Is it all it takes us like 10 people, or is it 1,000? Is it 50,000? I don't think it is generally a question of absolute numbers. A lot of people think you just have to hit some mark,. But really, there's 7-ish billion people in the world. There are always more people out there to sign up. It's just a question of how you turn on the spigot.
