It is a fair question.
If you are trusting someone with an important presentation, you want to know they have done this kind of work before. But I do not share client decks, before-and-after examples or project files. Not because there is nothing to show. Because the work is not mine to show.
Most of the presentations I support sit behind sensitive context, unfinished thinking, internal decisions, client conversations, investment cases or commercial priorities. At this level, discretion is not a nice extra. It is part of the work.
What I can share is the kind of organisations I have supported, the kinds of situations I am trusted with, and how the work usually happens: strategy updates, investment cases, client presentations, leadership meetings, board papers, market-entry stories and decks that have grown too large to be useful.
If you need public proof in the form of client decks, I probably won't be the right fit.
If you value discretion because you would expect the same for your own work, we are aligned.
