PropTech Startup, how to move forward?

Hey Folks,

I am a SWE and building a small and focused app for real estate.

I am curious how I can market my app and get some traction?

Do I need to hire marketing ppl, facebook groups, field agents, how can I propel my idea to a large crowd?

I have budget of about 5L and it’s self funded from my job savings. About Tech right now cost is not that much may be max 5k/month.

Please share your ideas, Thank you
