Unity Pro or Unity Personal for add-on creation?

My startup is making over $100K of gross revenue. I am interested in building an asset/add-on for Unity. Can someone please confirm that I need to purchase the Unity Pro license if I make over $100K of gross revenue even if I am building an asset and not publishing a game? Thanks in advance.

It’s all right there. You will know the circumstances. Basically if this asset is for your company, then yes, you need the license.

If it’s you personally doing it, then it depends on how much you make from Unity related services and sales - if it’s more than 100K, then yes. Else no.
