Advise to Grow a SaaS Product (no marketing knowledge)

So, I've been developing this SaaS application for a while now. It's a social media automation tool to schedule posts, generate content with AI & manage ig, twitter, fb like platforms. anyways I'm just curious how would you guys grow this type of product literally from scratch. Just the product is almost ready. I'm not into marketing, Im too invested into coding/building type stuffs. If any of you guys could give me some advice please. I'm trying to figure out a way whether it's paid ads, hire some influencer or idk i'm confused.
