TL;DR

  • Pick Attio if you're building a real sales motion, want AI features that act on your data, need a customizable data model, or expect to grow past 10 seats. Attio is the CRM you can scale a business on.
  • Pick Nimble if you're a solopreneur or small team doing relationship-led work (consulting, partnerships, business development) and you primarily need a smart contact database with social enrichment. Nimble is the CRM you can run a personal brand on.

Pricing

Nimble has one plan: $29.90/user/month (billed annually) for the Business tier. That's it — no free plan, no enterprise tier. Attio has a free tier for up to 3 seats with unlimited collaborators, Plus at $34/user/mo, Pro at $69, and Enterprise at $119. Attio's free tier is more generous than anything Nimble offers; at the $30–$35 price point, the two are close on cost.

Data model

Attio's flexible data model is the headline feature — every object is a configurable database (deals, accounts, partnerships, investments, anything). Nimble's data model is fixed around contacts and companies, with deal pipelines as a secondary view. For a contact-first relationship business, Nimble's structure is sufficient. For anything that needs custom objects, multi-pipeline complexity, or unusual data shapes (VC firm, real estate brokerage, creator partnerships), Attio is the only one that bends.

Social contact enrichment

Nimble's heritage is "social CRM" — its core differentiator since 2010 has been pulling rich profile data from LinkedIn, X, and the open web into contact records. Open an email in Outlook or Gmail and the Nimble sidebar shows the sender's job history, social handles, recent posts, and connection context. For relationship-led workflows where the value is knowing who you're talking to, Nimble's enrichment depth on individuals is hard to beat.

Attio's enrichment is newer and stronger on the company side — auto-enriched firmographic data, AI-generated summaries from public sources, and agentic actions that act on enriched data. For a sales team prospecting B2B accounts, Attio's enrichment is more useful; for a consultant managing 500 personal relationships, Nimble's is.

AI and automation

This is where the gap is largest. Attio in 2026 ships AI-generated fields, AI list-building, agentic CRM actions, and a deep automation engine — all on top of a modern API. Nimble has incremental AI features (AI-generated email and message templates, smart filters) but the platform isn't built around AI the way Attio is. If your interest is in AI-native CRM workflows, Attio is in a different generation.

Outlook and Gmail integration

Nimble's mailbox integrations are its second great strength. The Outlook sidebar and Gmail extension show enriched contact context inline, log emails automatically, and offer template messaging without leaving the inbox. Attio's Gmail and Outlook integrations are solid but more recent — they log emails and surface CRM context, but the inline enrichment experience isn't quite as polished as Nimble's after 12+ years of iteration.

Who should pick what

  • Solo consultant, advisor, or coach managing relationships → Nimble. The Outlook/Gmail sidebar plus enrichment is exactly the right shape.
  • Founder doing biz dev out of an inbox → Nimble for the first 1–2 years, Attio when you hire a salesperson.
  • Sales team of any size → Attio. Nimble's pipeline and reporting won't scale.
  • VC firm, partnership team, agency → Attio. The custom data model handles non-traditional workflows.
  • Microsoft 365 small business wanting a contact CRM → Nimble has the better Outlook story.
  • Anyone modernizing from a legacy CRM → Attio.

Bottom line

Nimble has carved out a durable niche as the "smart contact book with a great Outlook sidebar" — for one-person businesses and small relationship-led teams, it remains a sharp pick at $30/seat. Attio is a different category of product: a modern, AI-native CRM platform that bends to almost any data shape and scales with a growing team. The two rarely lose deals to each other because they solve different problems.

Frequently asked questions

Attio vs Nimble — which is better?
Different shapes. Attio is a full CRM with sales pipelines, automations, AI features, and a custom data model — built for teams. Nimble is a 'social CRM' for individuals — its core value is contact enrichment from social profiles and an Outlook/Gmail sidebar, not pipeline management. For 1-person businesses, Nimble can be enough; for sales teams, Attio is the right shape.
Is Nimble cheaper than Attio?
Nimble is $29.90/user/mo (Business plan) — the only paid tier. Attio is free for up to 3 seats, $34/user/mo (Plus), $69 (Pro), $119 (Enterprise). For small teams, Attio's free tier wins outright. At paid tiers Nimble is cheaper per seat than Attio Plus, but Attio's feature breadth is much wider at that price.
Which has better contact enrichment?
Nimble's contact enrichment from social profiles is a 15-year-old strength — it pulls bios, social handles, and recent activity. Attio's enrichment is newer but built on modern data providers and AI summarization. For pure social/web enrichment of individual contacts, Nimble's depth is real. For company-level enrichment and AI-driven data extraction, Attio is ahead.
Can Nimble handle a sales team?
Up to 5–10 people, yes. Beyond that, Nimble's pipeline tooling, reporting, and admin controls are too light for a real sales org. Most growing teams outgrow Nimble between 10 and 25 seats.
Which integrates better with Outlook?
Both have Outlook integrations. Nimble's Outlook sidebar is one of its core differentiators — it's been iterated on for over a decade and shows enriched profile data inline as you read emails. Attio's Outlook integration is competent but newer. For Outlook-centric workflows specifically, Nimble's sidebar is still the standout.
