Sluice vs Common Room
Common Room is a signal platform for go-to-market teams: it pulls intent, job changes, community and social engagement, website visits and custom signals into one account view, from $2,500 a month billed annually. Sluice covers a narrower set of public signals for small teams from $9 a month, scores each person, and drafts the first message.
What Common Room is good at
Common Room joins more kinds of signal than any small tool can: Bombora intent, job changes, social and community engagement, website de-anonymisation and custom signals you define, all resolved to people and accounts in one view. For a company with an active community (a Slack or Discord, a GitHub project, a forum) it shows which members work at target accounts and what they have been doing. It sends alerts and briefs to the people who should act, and connects to CRMs, sales engagement tools, Slack, webhooks and MCP, so it can sit at the centre of a larger go-to-market stack instead of beside it.
Use Common Room if: Pick Common Room if you have a sales or GTM team of five or more, an existing community or product-led motion producing signals, a CRM and sequencer already in place, and the budget for an annual platform that joins all of it into one account view.

Both read signals, at very different scales
Common Room and Sluice share an idea: the best time to contact someone is when they have just shown a sign of needing what you sell. They apply it to different companies.
Common Room is built to be the signal layer for a go-to-market team. It takes in intent data, job changes, social and community activity, website visits and custom signals, resolves them to people and accounts, and routes alerts to whoever owns each account. It assumes you have a CRM, a sequencer and several people to act on what it finds.
Sluice is built for the team that does not have those things yet. It reads a defined set of public sources (post engagers on eight platforms, competitors' reviewers, Google advertisers, companies hiring, local listings, your own site's visitors), scores each person against a customer profile, and drafts a first message from what they actually said. Sending happens only through accounts you connect, only for messages you approve.
A devtools startup's first quarter
Say you are a four-person startup selling an API monitoring tool. You have an open-source repository with some stars, a small Discord, and no sales hire. You want 50 good conversations this quarter.
On Common Room. Essential is $2,500 a month billed annually, so $30,000 for the year (as of October 2026). You get five seats, 100,000 contacts and 2,500 Prospector credits. It would tie your Discord and GitHub activity to companies, flag members at target accounts, add Bombora intent and website visits, and push alerts into Slack. That is a strong picture of who is warming up. You would still need somewhere to write and send messages.
On Sluice. Working is $39 a month, $117 for the quarter, with 5,000 credits in the first month. You set up signals such as "API latency alerts noisy" and "uptime monitoring alternative", which search Reddit, X, LinkedIn and YouTube for people discussing the problem. You paste a competitor's G2 page so its unhappy reviewers become leads. You add a directory search for platform engineering leads at companies hiring SREs. Each person is scored; those at 70 or more are worth contacting, and drafts are written from their own words. What Sluice cannot see is your Discord, your GitHub stars or third-party intent.
At this stage, the gap between $117 and $7,500 for a quarter is the deciding factor for most teams. The question to revisit later is whether your community has grown enough that its signals are worth a platform of their own.
How the signals differ
| Signal | Common Room | Sluice |
|---|---|---|
| Third-party research intent | Yes (Bombora) | No |
| Community activity (your Slack, Discord, forums) | Yes | No |
| Job changes | Yes | Yes, monthly re-read of people who scored well |
| Public social engagement | Yes | Yes, eight platforms, plus phrase searches |
| Website visitors | Yes | Companies that own their network only |
| Competitor reviews | Not a focus | G2, Capterra, Trustpilot, App Store, Google Play |
| Local businesses | Not a focus | By trade and town |
Sluice's visitor identification is deliberately limited: it works from who owns an IP range, so visitors on home broadband or mobile are not identified and not guessed. Most small companies on shared ISPs are invisible. If website visitors are your main signal, Common Room or a dedicated visitor tool will see more.
