I’m interested in starting an LLC as a sole proprietor/ sole partner. Is it possible to start a single LLC and use that business across industry lines or would it be easier / better to create subsidiaries under the original business for separate ventures? Ex: primary business is niche hospitality. Looking to add separately for a line of small batch wines and liquors, and possible bespoke personal goods (bags, totes, Fanny packs, etc). Can I potentially keep the one EIN / biz, but have it linked to multiple entities on the fictitious name registry?

Currently incorporated in Indiana, but located regionally in the Midwest. Thank you.
