We are actively thinking through this at Loom and it's not easy! It;s is about creating channels/spaces for the different audiences and making it easy for each audience to read what is relevant to them. So, for example, you could have different sections on your website for SMBs and Enterprise buyers - focusing on the different problems they have, or things they care about. You should try to have these audiences segmented in your database for email marketing.
As far as your homepage goes, going with the most universal language up top, and then perhaps having a section below the fold that links to a more specific Enterprise page, where you can focus on messages that these buyers care about like security or admin features.
