What is Sumble? Data, plans, API and cost per call
Sumble is an account intelligence tool for sales teams. It shows which teams inside a company use which technologies, who leads them, what they are hiring for and which projects are active. Free includes 500 credits a month, Pro costs $99 per user a month with 9,900 credits, and Enterprise is custom. The API and MCP server work on every plan. Agents can also call Sumble per request through Locus Pro, with no seat. Prices checked November 10, 2026.
What does Sumble do?
Sumble builds a structured view of each target account: teams, reporting lines, technologies, hiring activity and buying signals. Sales reps use it to decide who to contact, why now and what to say.
Sumble’s own example shows the difference. A technographics tool might say a bank uses Grafana. Sumble names the team that uses it, how many people that team has, who leads it, and when it last posted a job that mentions Grafana.
It is built for teams that sell into technical or complex accounts. Sumble says it covers millions of companies.
What data does the Sumble API return?
Each core endpoint works the same way. You send a list to resolve or a filter to search, then pick the fields you want back. You pay only for what you pick. Credit costs below are Sumble’s, from its API docs on November 10, 2026.
| Endpoint | What it returns | Sumble credits |
|---|---|---|
| Organizations | Companies by name, domain or filter, with firmographics and per-technology metrics | 1 per company, plus 1 per paid field and any metrics. Unmatched inputs are free. |
| People | People by LinkedIn profile, work email or company, with managers and reports | 1 per person, plus paid fields. Email reveal 10, phone reveal 80. |
| Job posts | Descriptions, technologies, teams and hiring managers | 1 per job, plus paid fields and related people |
| Teams | Teams with ICP fit score, members and job posts | 1 per team, plus fields, people and job posts |
| Signals | Recent account events such as hiring and migrations | 1 per signal returned |
| Intelligence briefs | An AI-written account brief | 50 per completed brief |
| Lookups | Canonical IDs for technologies, projects and job titles | 1 per 100 matches, or 1 if found |

What does a typical Sumble job cost?
Say you enrich 1,000 companies and ask for 3 paid fields each. That is 1,000 base credits plus 3,000 field credits, 4,000 in total. It fits in one month of Pro, and at the Pro rate it is worth about $40.
Contact reveals cost more. Revealing 100 work emails uses 1,000 credits, and 100 phone numbers use 8,000. Ten intelligence briefs use 500.
The API allows 10 requests a second per user. A request that runs past 55 seconds stops and is not charged.
Can an agent call Sumble without a seat?
Yes. Locus Pro offers Sumble’s data lookups and searches, billed per call to one prepaid credit balance with no Sumble seat. Each call is priced at call time from the rows and fields you request. Send max_credits on large requests to cap the charge. Catalog checked November 10, 2026.
Locus does not offer Sumble’s organization tech stack, signals or saved lists endpoints.
The same balance pays for Apollo, Hunter and other providers. A monthly limit stops new calls when you reach it. Platforms can also bill their own customers for the lookups their agents run.
| Locus endpoint | What it returns |
|---|---|
| sumble/organizations | Companies with firmographics and technology metrics |
| sumble/people | People with their managers and reports |
| sumble/jobs | Job posts with technologies and hiring managers |
| sumble/teams | Teams with their members and job posts |
| sumble/intelligence-brief | An AI-written brief on one account |
| sumble/technology-find | Technologies that match a name |
| sumble/technology-lookup and other lookups | Canonical IDs for technologies, projects and job titles |
Which way of buying Sumble fits?
Choose by who uses the data and how often.
- A rep who researches accounts in Sumble every day: Pro, for the app, Ask Sumble, Slack signals and 9,900 credits a month.
- A RevOps team that wants Sumble data in its CRM or warehouse: Enterprise.
- An agent that needs team and technology data now and then, next to Apollo or Hunter lookups: Locus Pro, billed per call with no seat.
- Website technology detection only: BuiltWith may be enough. Compare it first.
