Common Room reads outward-facing signal: social activity, community membership, product usage, job changes, website behaviour. Its raw material is other people's public behaviour toward you.
Relationship intelligence reads your own team's history: who they worked with, who they email, who they meet. Its raw material is your company's private interaction record and public employment history.
So a person has to have done something near your brand to appear in Common Room. They do not have to have done anything at all to appear in a relationship graph - they only have to be known by someone on your team.
| Situation | Common Room | Relationship intelligence |
|---|---|---|
| Someone engaged with our content | Yes | No |
| A champion changed jobs | Yes | Yes |
| We need into an account that has never heard of us | No | Yes |
| Who at our company can introduce me | No | Yes |
| Developer community or PLG motion | Strong | Weak |
| Named enterprise account list | Weak | Strong |
The honest split: if you have a community or a product-led motion generating signal, Common Room is reading something real that nothing else sees. If you are working a named list of enterprise accounts cold, it has very little to tell you, because those accounts are not in your community.
Job changes. Both categories track when a known contact moves, and it is the highest-intent signal in B2B either way. UserGems does only this, if that is all you want.
The difference is what happens next. Common Room tells you the person moved. Relationship intelligence tells you the person moved and who else at your company already knows people at the new employer - which turns one warm contact into a mapped account.
They stack cleanly because they do not compete for the same job:
Quicklizard wanted a prospecting channel built on warm relationships that would not drain SDR time; mapping career overlaps across their extended network produced a continuous stream of warm paths into retail and e-commerce targets. No community signal would have found those accounts, because the buyers had never interacted with them.
