Choose Klovis if you want multi-channel outreach across LinkedIn, email, WhatsApp, Instagram DM and Telegram with a unified inbox and pipeline attribution, and choose Attio if you want a flexible, highly customizable CRM platform to model your own data and processes.

Klovis vs Attio compares a multi-channel outreach CRM with a flexible CRM platform. Attio is a modern, highly customizable, data-driven CRM you can shape to almost any object model, with powerful reporting and automation building blocks. Klovis is an outreach CRM that messages prospects across LinkedIn, email, WhatsApp, Instagram DM and Telegram, then unifies every reply and turns it into pipeline.
Attio is the place to model and report on your data with precision. Klovis is the engine that actually runs the outreach across channels and traces each reply back to the campaign that produced it.
| Capability | Klovis | Attio |
|---|---|---|
| Channels | LinkedIn, email (Gmail / Outlook / IMAP), WhatsApp, Instagram DM, Telegram | Email and calendar sync; outreach via integrations |
| Unified inbox | Every reply from all five channels in one attributed inbox | Email and activity captured against flexible records |
| Built-in CRM | Self-updating people, companies and deals tied to campaign replies | Highly customizable CRM with custom objects, views and reporting |
| Automation | Event-driven workflows that send outreach and book meetings | Powerful automation builder across objects, plus integrations |
| Attribution | Replies attributed to contact and campaign, surviving pause and resume | Flexible pipelines and reporting you configure to your process |
| Pricing model | Per-seat plans for multi-channel outreach and CRM | Per-user plans tiered by features and data volume |
Klovis sends natively on five channels, with the channel chosen per step inside a campaign: LinkedIn connection requests and messages, email through Gmail, Outlook or IMAP, and direct messages on WhatsApp, Instagram DM and Telegram.
Attio is a CRM platform rather than an outreach tool. It syncs and tracks email and calendar activity and connects to outreach tools through integrations, but it does not natively run sequenced LinkedIn, WhatsApp, Instagram or Telegram campaigns.
If you want to model data and bolt outreach on through integrations, Attio is flexible; if you want sequenced sending across LinkedIn and chat apps out of the box, pick a native outreach engine.
Klovis routes every reply from all five channels into one inbox, each conversation attributed to the prospect and the campaign that produced it, so LinkedIn, email, WhatsApp, Instagram and Telegram threads sit together.
Attio captures email and activity against richly modeled records and offers a strong communications view tied to your data, but it is not designed as a live, multi-channel social-messaging triage queue the way Klovis is.
Decide whether you need email and activity attached to flexible records, or a live inbox spanning every outreach channel your prospects reply on.
Klovis includes a CRM of people and companies that updates itself as outreach and replies happen, and replies convert into deals that move through pipeline without a separate sync step.
Attio is the more powerful, configurable CRM platform: custom objects, attributes, views and reporting you can tailor deeply. The difference is focus: Attio leads with data modeling, while Klovis ties records directly to multi-channel outreach activity.
Pick Attio when deep custom data modeling and reporting are the priority, and Klovis when you want a CRM that fills itself from native multi-channel outreach.
Attio offers a strong automation builder with triggers and actions across your objects, plus integrations to push data and trigger outreach in other tools. Klovis adds event-driven workflows that fire on triggers like a record being created or updated, a tag added, a field change, a reply, or a no-response, and crucially those workflows send the outreach themselves across channels and move a prospect toward a booked meeting.
Say a prospect accepts a LinkedIn connection and replies.
Attio gives you flexible pipelines and reporting you can model precisely, with deal stages tailored to your process. Klovis turns a reply into a deal in the same workspace, attributed to the contact and the campaign that produced it, and that reply history is tracked per campaign and survives pause and resume, so attribution from outreach to revenue is built in rather than configured.
In Attio, a rep books the meeting from the record and your configured process, with the activity tracked against the deal. In Klovis, meeting-booking lives in the automation layer, so a workflow can move a prospect toward a booked meeting automatically, all attributed to the same contact and deal.
Klovis is built for teams whose priority is running multi-channel outreach: founders selling across LinkedIn and chat apps, SDR teams coordinating replies, and revenue teams that want deals to update themselves from native messaging.
Attio is built for teams that want to design their own CRM: operators, RevOps and data-driven teams who value custom objects, flexible reporting and a modern, configurable platform.
If you have modeled your data beautifully in a flexible CRM but still rely on separate tools to actually message prospects across LinkedIn, WhatsApp and Telegram, and reply attribution lives in yet another place, that gap is the signal you need a native multi-channel outreach engine.
Attio imports and models contacts, companies and custom objects with a great deal of flexibility, and syncs email and calendar. Klovis keeps records in one place too, because the CRM is part of the product, so migration means bringing your lists into the Klovis CRM and rebuilding your motion as multi-channel campaigns sent from your connected accounts.
