The companies that win spread the posting. Most are capped at one person.

The single clearest signal of whether a company is capturing the multiplier is how spread out its reach is. If many people post, the reach comes from many networks.

If it all comes from one person, the company is capped at that one person's audience, no matter how big the headcount behind them. So for a set of well-known companies we measured the share of all employee-advocacy reach produced by the single biggest poster.

The split is stark. At most companies, one person accounts for 75% to 95% of everything, Oracle, SAP, IBM, Capgemini, L'Oréal, and even fast-growing GTM names like lemlist and ColdIQ lean heavily on a single founder.

Twenty people at IBM clear our activity bar; nineteen of them together are a footnote next to one. Those companies are not capturing the multiplier; they have a prolific executive, which is a different and far more fragile thing. The day that person slows down, the reach goes with them.

The companies that break the pattern are the ones to study. At Salesforce the top poster accounts for just 29% of reach, at HubSpot 32%, meaning two-thirds of their reach comes from a genuinely broad cast, sellers, marketers, engineers, not one star.

For full disclosure, our own company sits in that healthy band too (41% across ten advocates), and we include ourselves precisely because the only program worth writing about is one you can measure on yourself.

The same goes for your own team. Before you decide your advocacy is working, look at the analytics that show where your reach actually comes from.

The gap between a Salesforce and an Oracle is not talent or headcount. It is how many people actually post. And that gap is exactly the reach most companies are leaving on the table.
