Don't forget that a pinned post on Instagram (or Facebook too) is a way to give yourself more of an introduction and tell your audience (or prospective audience members) what you're about. Thought leaders, influencers, speakers and similar can elaborate much more about who they are, what they're bringing to the table, give the why behind what they do or the core message they deliver, and provide more detail on how to do business. I've seen a few do a carousel-style post in which the first image is "Start Here!" making it obvious that new or potential followers should read that pinned post. You, your business, and your ideas are more than 4-6 lines in name/bio boxes, so make use of other elements that can remain close to the top and let people meet you.
