GTM ClubProduct-led works when someone can get value alone in a session, and when that value spreads inside a company by itself. It produces a lot of users and a little revenue per user, so the sales work moves to spotting the accounts where usage is turning into a real deployment.
That is where outbound comes back: product usage is the richest buying signal there is, and "product-led sales" is just signal-based prospecting on your own data.
