First ask whether you truly lack experience or only lack publishable material
Some teams are not short on experience at all. What they lack is material that can be shown publicly. The client name may be confidential, screenshots may be restricted, and commercial details may be sensitive. That still does not mean there is nothing useful to present.
Separate “we have not done this before” from “we have done it, but cannot disclose it directly.” The second situation can still support a strong page if you shift the structure away from logos and before-after claims toward problem types, delivery scope, constraints, and working approach.
Can you mention the client, industry, or timeline at all?
Can you describe the problem category and delivery scope?
Can you explain the method, decisions, or stage outputs without exposing private details?
