Startup founders, how are you marketing your product today?

Hi all! We launched a product last month and are launching more this year and were wondering what the best way to market products today is and what you all were doing to drive more sales. Do you try to increase your social presence and the build products? Or do you rely on other influencers to help you out? Also, if you do affiliate marketing for your startup, do you see great rewards? Thanks in advance!
