The short version

  • Only Trumpet has a free tier, so it costs nothing to try first.
  • Each has a real cost: Common Room the entry plan is 2,500 US dollars a month billed annually, a floor of 30,000 a year, which excludes exactly the early-stage community-led companies whose signal is strongest.; Trumpet e-signature, proposals and quotes are held back to the Scale tier at 100 US dollars per user per month, so a team on Pro still needs a separate signing tool and pays twice for one workflow.
  • They diverge on capability: Common Room covers Person360 identity resolution, Trumpet covers Pods.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Common Room

  • The entry plan is 2,500 US dollars a month billed annually, a floor of 30,000 a year, which excludes exactly the early-stage community-led companies whose signal is strongest.
  • RoomieAI and Prospector run on credit allocations rather than unlimited use, so heavy research months exhaust the budget and the workflow stops until the next cycle or an upgrade.
  • Contact ceilings of 100,000 on Essential are consumed quickly by any sizeable public community, and the overage conversation is an upgrade to a quoted tier rather than an incremental charge.
  • Identity resolution is probabilistic, so wrong merges happen, and a seller who contacts the wrong person with context from someone else does more damage than no alert at all.
  • Signal volume overwhelms teams without a defined qualification rule; most implementations that fail do so because everything became an alert and sellers stopped reading them within a month.

Trumpet

  • E-signature, proposals and quotes are held back to the Scale tier at 100 US dollars per user per month, so a team on Pro still needs a separate signing tool and pays twice for one workflow.
  • Single sign-on and SCIM only appear on Elite at 160 per user per month, which puts basic enterprise identity controls behind the most expensive tier rather than treating them as security baseline.
  • Pro is capped at five users, so a sixth hire forces a jump from 45 to 100 per user per month, more than doubling the per-seat cost for a headcount reason.
  • A digital sales room only works if buyers actually use the link, and in industries where procurement insists on email attachments and its own portals, the engagement analytics that justify the spend never materialise.
  • It competes against enablement platforms that bundle rooms into a wider content and coaching suite, so organisations already paying for one of those are buying an overlapping capability rather than a missing one.

Answered from the vendors’ own pages

Common Room: What does the entry plan actually cost?

2,500 US dollars per month billed annually, for 5 seats and 100,000 contacts. Higher tiers are quoted.

Trumpet: Is the free plan genuinely usable?

Yes. Ten pods per account with unlimited users, mutual action plans and integrations is enough to run real deals, not just a trial.

Common Room: Is this only for developer tools companies?

It is strongest where there is a public community to observe. Companies with no community signal get a narrower version of the product and should compare it against ordinary intent data vendors.

Trumpet: When do I need to pay?

At the eleventh pod, or when you need e-signature and proposals, which start at Scale on 100 US dollars per user per month.

Common Room: Does it replace ZoomInfo?

No. It is signal and identity resolution rather than a contact database, though Prospector covers some contact discovery within accounts.

Trumpet: Where is the company based?

London, United Kingdom, which matters for procurement teams that prefer a UK or EU contracting entity.

Common Room: How are AI features metered?

By credits per tier, from 5,000 RoomieAI credits on Essential up to 10,000 on Enterprise, with Prospector credits counted separately.

Trumpet: Does it replace PandaDoc or DocuSign?

From Scale upward it can, since signing happens inside the pod, though it also integrates with both if you want to keep them.
