I am not active on social media, but I know that I have to be active because of my job as a startup founder. Where and how should I get started?
Start by posting on your Facebook profile, create FB page, LinkedIn account, Instagram and Twitter accounts. Start posting about you and your startup. It will take some time, but slowly and gradually you will build up following. If you can do videos, start YouTube channel too. If you are busy in your startup day to day activities, hire someone to take care of postings on your behalf.
