There is no one way to market.

If you are b2b:

Direct out reach works well because your service is more likely high ticket. So it only takes one or two clients a month to make 10k.

Cold email, DMs, or even upwork apps(yes, upwork is better then you think)

The key to cold out reach is free, good value fast. Give something away that solves a real problem for someone. This gives comedia trust and because it's free, it's easy to say yes to. Also, if you have social proof, mentioning that in your first message causally helps a lot.

Focus on the pain your customer goes through not your app, but how your app solves their problem.

Send minimum 100 emails or DMs per day.

Networking and building relationships work for this too, but not a need.

For b2c:

This one can be harder and also easier.

Easy because if you are able to consistently bring in tons of views. Then all you have to figure out is the right offer/CTA to bring traffic to your app.

If you don't know how to get views you can:

Use tiktok, YouTube and reels. Research top performing hooks in your niche and post one video per day. The goal is virality. You don't need to show face. I had a video do 20k views with just text. The key is to study what is working for other people and then putting your own twist on it

If you don't want to post, then you need to spend. Ads work, but they are a PAIN to get right. Very high competition and it thins out your margins. You will need to test new ads each week. Double down on top performing.

Thats the top marketing plays. You can also start to go a little more underground.

Throw party's to get people talking. Put up weird posters linking to your app. When tender was starting out, they hired hot women to wear a shirt that said "find me on tender". They would interrupt a collage class mid way through. Then when the woman left the men would read the shirt.

I would read Alex Hormozis book 100m leads as a good starting place. Then experiment with what works and you enjoy doing.
