Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.
Starting price
$2,500/mo
Customer intelligence that unifies community, product, CRM, and web signals. Essential is $2,500/mo billed annually.
Where Common Room fits
$99/mo Free tier 30 day free trial
Sumble shows the teams, tech, reporting lines and hiring activity inside a target account and alerts you when they change. It suits agency recruiters and business development reps who sell into specific teams, such as data or platform engineering, rather than whole companies. There is a free plan with 500 credits a month, Pro is $99 a month, and a work email unlocks 30 days of Pro free.

Common Room
Stands out: Person-level buyer intelligence across community plus product plus CRM (RoomieAI and MCP included on Essential), not a $49 visitor-ID pixel.
Watch out: $2,500/mo is 5 seats and 100k contacts on Essential. This is a GTM platform, not a recruiting pixel.
Not the right fit for
Sumble
Stands out: Most signal tools tell you a company uses a technology, while Sumble breaks that down by team and attaches the people and reporting line behind it. That makes it sharper than a company-level lookup in BuiltWith when you need to know which hiring manager to call about a new data team.
Watch out: The free plan only shows the first page of results and 8 signals a week, so real prospecting needs Pro. CRM and warehouse sync to Salesforce, Snowflake and Databricks sits on the quote-based Enterprise plan.
