Apollo.io vs Attio
A plain-English comparison to help you choose between them.
Run sales from the data platform or from the system of record: Apollo bundles a vast contact database, enrichment and outreach sequences into one affordable motion, Attio is an agent-first CRM whose records keep themselves current. Pick Apollo when finding and contacting prospects is the bottleneck, list to sequence in under an hour, with a free tier and per-seat pricing that scales with headcount. Pick Attio when the CRM itself is the bottleneck, auto-logged email and calendar activity, native enrichment, a data model that flexes to how you actually sell, and research agents working pipeline inside the record. Plenty of teams end up running both, one to source the pipeline and one to keep it true.
Side by side
- Summary
Apollo is all-in-one sales intelligence: a large contact and company database, enrichment, and outreach sequences in one platform at a price small teams can actually run.
- Best for
- Prospecting from a large built-in contact database
- Enrichment and outreach sequences in one platform
- Small teams running the whole motion affordably
- Cost
- Freemium (Free tier + paid plans)
- Ease
- Openness
- Hosted service
- Data
- Prospect and engagement data live in Apollo's platform; contact data accuracy varies by segment, so verify before high-volume sends.
- Summary
Attio is an AI CRM built around agents working the system of record; its own framing is the CRM for agentic revenue.
- Best for
- A system of record with research agents working it
- Native enrichment and auto-logged email and calendar activity
- A flexible data model shaped to how the company sells
- Cost
- Freemium (Free tier + paid plans)
- Ease
- Openness
- Hosted service
- Data
- Attio's convenience features are data-ingestion features. Automatic enrichment fills records from external sources, and the context layer logs emails, calls, calendar and integration data onto records without anyone deciding case by case, which is personal data processing at scale. For EU-serving teams the GDPR lawful-basis judgement sits with the customer as controller, not with the vendor, so decide the basis for enrichment and auto-logging before switching them on and scope which mailboxes and calendars connect. It is a closed, hosted platform, so records live on the vendor's infrastructure; the API, webhooks and developer surface provide export and integration routes, and current data-processing terms deserve a read rather than an assumption.
By area
Where each one pulls ahead, area by area.
| Area | Pick Apollo.io when | Pick Attio when |
|---|---|---|
| Founders & entrepreneurs | a startup needs the leads database, engagement and CRM-lite in one subscription | Attio starts at the system of record and adds agents to work it |
| Sales | finding contacts is the bottleneck and a leads database with engagement sequencing covers more of the gap | Attio is the system of record with agents working it |
Common questions
Where does each one's data come from?
Apollo owns a large single-source database, good enough for volume prospecting but behind the multi-provider waterfalls where precision decides, so samples deserve checking before big sends. Attio does not sell you a database; it enriches the records your motion creates and logs the activity around them, so its data quality tracks your pipeline rather than a vendor's coverage.
What do the free tiers really demonstrate?
Different things, usefully. Apollo's free tier runs the actual motion in miniature, list-building and sequencing included, so a founder can test the workflow before paying. Attio's free plan carries up to three seats with syncing and enrichment, a genuine zero-cost system of record, but the agents that define the pitch sit on Pro tier and above, so the free plan demonstrates the data model more than the agentic product.
What compliance homework do they share?
Personal data at scale, on both sides. Attio's enrichment and auto-logging ingest prospect and customer data wholesale, and for EU-serving teams the GDPR lawful-basis responsibility sits with the customer, not the vendor. Apollo's sequences add deliverability duties the platform cannot carry for you. Rollout on either is a data-protection decision as much as a tooling one.
