Nimble is a social-relationship CRM aimed at solopreneurs, small teams, and SMBs that live inside Microsoft 365 (Outlook) or Google Workspace (Gmail).
Vertical: horizontal CRM / social-relationship management for SMBs. Sub-vertical: Microsoft 365- and Google Workspace-centric small businesses. Sales reps and small-business owners install the Nimble Prospector extension in Chrome/Edge and the Outlook or Gmail add-in, then use Nimble as the system of record for every prospect and customer relationship.
Nimble is a recognized SMB CRM brand with 4.5/5 across ~1,100 G2 reviews, 4.4/5 across ~1,900 Capterra reviews, and Forbes' '2025 Best CRM for Solopreneurs and Small Teams' designation, but its absolute install base is materially smaller than HubSpot (~289k paying customers), Pipedrive, Zoho, or Salesforce.
Yes, for tens of thousands of small businesses, Nimble is the system of record for the customer-relationship dataset: the master contact and company database with social-enriched profiles and custom fields, the deal pipeline and sales forecast, every logged email/call/meeting/message with timestamps, email-marketing campaign and sequence history with opens/clicks, web-form and live-chat lead capture, tasks and reminders, segments and tags, and the OAuth/email-sync configuration that ties Nimble to the user's Outlook or Gmail mailbox.
Founded 2009 in Santa Monica, CA by Jon Ferrara, the co-founder of Goldmine Software (one of the original PC-era contact managers acquired by FrontRange in 1999).
No documented native outbound webhooks, integrations must poll contacts/deals/teams endpoints or rely on Zapier / Make triggers for change detection. Per-account rate limits are enforced but undocumented; HTTP 429 is returned without published request-per-minute/day ceilings, forcing trial-and-error backoff. Full sourced list under Sources below.
Common alternatives include HubSpot CRM, Salesforce Sales Cloud (Essentials/Starter), Zoho CRM, Pipedrive, Freshsales (Freshworks), Microsoft Dynamics 365 Sales. Graded alternatives appear under "More from the report card" below.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Not that we could find. As of August 2026 there is no official Nimble MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. Nimble doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
