Attio

StackScore Tools™
66/100

Attio is a modern, highly flexible CRM built for fast-moving startups and scale-ups that have outgrown spreadsheets but find legacy CRMs like Salesforce suffocating. Its Notion-style customization and AI-powered data enrichment are genuinely impressive, but thin native integrations and immature reporting hold it back from replacing enterprise-grade tools.

4-Layer StackIndex™ Breakdown

Strong core CRM utility and fast onboarding are well-documented across 284 G2 reviews, but recurring integration failures and email-only last-interaction tracking drag the score down from what could be an 80+ rating.

SOC 2 locked to Enterprise tier, ambiguous training data policy, and no visible status page or postmortem culture limit trust for compliance-sensitive buyers — the Capterra customer service score of 3.1 adds a further flag.

Steady G2 review growth with 284 reviews and a credible AI/MCP narrative earns Attio reasonable market presence, but the absence of disclosed funding data and limited enterprise customer logos constrains the ceiling.

Attio's REST API, webhooks, MCP support, TypeScript React App SDK, and active 2026 changelog represent genuinely modern developer infrastructure, though tight rate limits on lower tiers and some awkward write operations prevent a top-tier score.

Insta's take

Attio arrives with a simple, seductive pitch: a CRM that feels like software built in this decade. And for the first time in years, that claim mostly holds up — the Notion-style interface, sub-30-minute setup, and MCP integrations that let AI agents talk directly to your pipeline are genuinely impressive. The question isn't whether Attio is good. It's whether it's good enough for where your team is headed.
