Attio vs Nutshell (2026)

TL;DR

• Pick Attio if you want a modern, AI-native CRM that bends to your data model, integrates with the modern stack (Slack, Linear, Notion, Stripe), and gives you room to scale into 50–200 seats. The free tier for 3 seats is real.
• Pick Nutshell if you're a 5–25 person SMB sales team in services, manufacturing, distribution, or insurance, you want a simple opinionated CRM, and bundled email marketing is genuinely valuable rather than something you'd replace with a dedicated tool.

Pricing

Nutshell has the widest plan ladder in the SMB CRM segment. Foundation at $13/user/mo gives basic CRM. Growth at $25 adds sales automation. Pro at $42 adds email marketing. Business at $59 adds more advanced reporting and integrations. Enterprise at $79 covers SSO, custom reports, and white-glove onboarding. Attio's tiers are flatter — free, $34, $69, $119 — with most features unlocked at Pro ($69). For a 10-seat team mostly on entry tiers, Nutshell saves $120–$200/month. At the Pro tier the cost difference is negligible.

Data model and customization

Attio's flexible data model is its single biggest differentiator. Every object is a configurable database — you can model deals, accounts, partnerships, candidates, investments, properties, anything. Nutshell's data model is fixed around contacts, companies, and leads, with limited custom field flexibility. For traditional B2B sales (manufacturer → distributor → end customer), Nutshell's defaults are fine. For anything unusual, only Attio bends.

Email marketing

Nutshell Marketing is a genuinely useful inclusion. Most CRMs at the SMB price point require a separate email tool (Mailchimp, ActiveCampaign, Constant Contact) — Nutshell built one in. It's not the equal of dedicated tools, but for an SMB sending 2–10k marketing emails a month it's enough and removes a stack item. Attio doesn't have anything equivalent — you'd pay $50–$200/month elsewhere for that capability.

AI

This is the largest gap. Attio in 2026 ships AI-generated fields, AI list-building, agentic CRM actions, and a deep automation platform — the product is built on the assumption that AI is a primary surface. Nutshell has incremental AI features (AI-suggested next steps, AI-drafted emails) but the platform's bones are pre-AI. If your interest is in AI-native CRM workflows, Attio is in a different category.

Pipeline and sales workflow

Nutshell's strength is its opinionated, pre-built sales process — kanban pipelines, automated stage transitions, follow-up reminders, lead routing — all out of the box, configured fast. Attio gives you the primitives to build the same workflow but expects you to configure it. For a team that just wants a working pipeline tomorrow, Nutshell is faster to set up. For a team with a non-standard sales process, Attio is more durable.

Who should pick what

• Modern SaaS company, 5–50 seats → Attio. Better fit for the stack, AI features, and growth path.
• SMB services business (consulting, agency, professional services) under 25 seats → Nutshell. The bundled email marketing and opinionated workflow fit the motion.
• Manufacturer, distributor, or wholesaler with a traditional sales process → Nutshell. Out-of-the-box pipelines fit traditional B2B sales.
• VC firm, partnership team, real estate brokerage → Attio. The custom data model handles non-CRM-shaped workflows.
• Sales team that needs email marketing in the CRM → Nutshell saves a stack item.
• Series A/B startup → Attio. Better scaling story, better integrations with the modern stack.

Bottom line

Nutshell has earned a loyal base of SMB sales teams who don't want a CRM admin headache — it's opinionated, bundled, and competent. Attio is the right answer for teams that want a CRM that bends to their workflow and is built for the AI era. The decision usually comes down to whether you're optimizing for "simple and good enough" (Nutshell) or "flexible and modern" (Attio).
