Marketing strategy for early-stage startup

Hi!

I'm a first-time founder and now we with my co-founder are working on launching our solution. We are working on a b2c service that visualizes what people feel based on their notes. Our potential users are women 18-29 who are interested in feeling better.

I'm non-technical so marketing is in my responsibilities. Now I am trying to create something like a marketing strategy for this early-stage launch, and I would like to know your opinions about it, maybe I missed something that could work for us.

In my plan, we start by announcing in personal social networks, like LI, Ig and meeting new people on offline events.

We also would try to have some paid or unpaid announcements in groups on Fb about health, well-being, new apps, AI (we use AI in our service), women entrepreneurs supportive communities.

We were thinking about Tinder Ads, but I didn't have any reviews of it.

We also plan to work with influencers on Ig and YT, maybe TikTok.

And also would like to try Google Ads, IG ads, YT ads.

​

Have you tried something of it? How it was? Maybe I missed something that worked for you in similar cases?
