Kommo vs Attio: Next-Generation CRM Comparison for B2B Teams

Attio is a next-generation CRM: a flexible data model without a rigid schema, API-first architecture, built-in analytics, Gmail/Google Calendar integration out of the box. Positioned as “the CRM you build yourself” — shaped to your data model, not the other way around. Kommo is a CRM focused on pipeline and messengers: WhatsApp, Instagram, Telegram in a unified inbox. Choosing between them is a choice between data model flexibility (Attio) and omnichannel communications (Kommo).

The Fundamental Difference: Data Model

Attio builds a CRM as a database with custom objects. A standard CRM has “Deals,” “Contacts,” “Companies” — and you adapt your processes to fit those objects. In Attio you create any objects: “Investors,” “Partners,” “Candidates,” “Products” — with their own fields and relationships. Flexibility on the level of Notion or Airtable, but with CRM logic on top.

Kommo uses a standard CRM schema: Leads -> Deals -> Contacts -> Companies. Custom fields are available, but objects are fixed. In return, messengers are a native part of the platform.

Comparison by Key Parameters

When to Choose Attio

Non-standard data model. If your processes do not fit into “Leads-Deals-Contacts” — Attio lets you create a “Pilot Program” object with its own stages and relationships. VC funds, HR firms, investment teams — this is why they use Attio.

API-first operations. Attio’s API is one of the best in the CRM category: predictable endpoints, filtering support for any field, webhooks on any object change. For teams that automate through code — Attio is significantly more convenient than most traditional CRMs.

Gmail as the primary channel. Attio syncs Gmail bidirectionally: all emails with a contact automatically appear in their profile, sending from Attio goes through Gmail. For teams where email is the primary sales channel.

Small and technical ICP. Seed-stage startups, VC funds, boutique consulting firms where 2–10 people work with 50–200 key relationships — Attio is ideal. Not overloaded with features, flexible, cheaper than Salesforce.

When to Choose Kommo

Messengers as the primary channel. If clients write via WhatsApp, Instagram, Telegram, Facebook Messenger — Kommo is the only CRM with a native unified inbox for all these channels. Attio has no messenger integrations.

High volume of leads from multiple channels. 50+ leads per month from different sources (form, social media, ads, WhatsApp) — Kommo handles this through a unified inbox. Attio is not designed for high volumes of inbound leads.

Digital Pipeline automation. Kommo Digital Pipeline is a visual automation builder: when a deal moves to a stage -> send a WhatsApp template message. Attio Sequences are more limited, without native messengers.

International market, EU clients. Kommo has EU hosting and works well for B2B with EU clients. Documentation is available in multiple languages.

Migration Between Systems

If you are on Kommo and considering Attio — the main challenge is migrating custom fields and activity history. The Attio API allows importing data, but object mapping is non-trivial. If you are on Attio with a non-standard data model and want to move to Kommo — you will lose schema flexibility but gain messenger capabilities.

A full data transfer from one CRM without losses is a separate project, similar to migrating from Kommo to HubSpot.

Real-World Case: VC Fund on Attio, Agency on Kommo

VC fund (10 people, Attio): needs “Startup,” “Founder,” “Deal (investment)” objects with custom relationships. The CRM logic is non-standard — rounds, co-investors, portfolio. Attio allows building this without customization.

Digital agency (15 people, Kommo): primary channel is Instagram and WhatsApp. 80% of new leads come through direct messages. Kommo unified inbox + automatic response via template on the first incoming message — critical.

Who Should Choose What

Kommo — sales teams with messengers, high inbound volume, EU/international market, standard CRM pipeline.

Attio — tech teams with a non-standard data model, Gmail as the primary email channel, VC/PE/HR companies, API-first approach to automation.

Frequently Asked Questions

Does Attio support a mobile app?

Yes, Attio has iOS and Android apps. But there are no messenger integrations (WhatsApp, Telegram) — only via email and calls. The Kommo mobile app includes a full inbox with messengers.

Attio API vs Kommo API — which is better for custom integrations?

Both have REST APIs with webhooks. Attio API is more flexible for custom objects and filtering. Kommo API is better documented in English and has a larger community. Custom integrations for Kommo are standard practice for agencies.

Does Attio have an equivalent to Digital Pipeline?

Attio Sequences — automation based on object state: “if status changed -> send email via Gmail.” Less visual, no messenger triggers. For complex email automation, Attio integrates with Zapier or n8n.

Can Kommo and Attio be used simultaneously?

Technically yes — via a bidirectional API. Kommo for inbound via messengers, Attio for strategic partnerships with a non-standard data model. A rare scenario, but encountered with teams that have two distinct sales processes.

Summary

• Kommo wins on messengers (WhatsApp, IG, Telegram), Digital Pipeline automation, high lead volume
• Attio wins on data model flexibility, Gmail integration, API-first architecture for non-standard use cases
• The key question: is your primary channel messengers or email? The answer determines the choice
• Transitioning between systems requires data mapping and is not trivial
