Is social media necessary to start a coaching business?

Hi all!

I'm wondering whether you think social media is necessary to start up a coaching business, namely, for finding clients. What are your thoughts? I ask because I'd love to find clients in-person or through word of mouth, rather than start a social account and have to create & post content. I am no longer an IG user & never had tiktok & I feel so much better without it in my life. I'm a bit resistant to the idea, if I'm honest :), however, I'm also keenly aware that social is where a lot of people find services and so I wonder if an alternative method(s) is possible.

I'd love to hear your thoughts!
