For growing startup founders – How did you acquire your first 100 users? (coherence.finance)

Hey guys. I'm a young first-time startup founder who is working on attempting to get some early usage for my newly launched app. I was wondering what kind of advice founders running successful companies have for getting your first 100 users, your first 1000, and your first 100,000. Would love to hear about strategies for growth, what you did, what technologies and softwares you used, etc. If anyone would be willing to hop on calls and give advice syncronously I would absolutely love to discuss. Just looking to learn. Thanks!
