Zero vs Attio

Zero vs Attio: which CRM fits a startup sales team?

Attio is a flexible, customizable CRM database that mid-market and RevOps-led teams build their own system on top of. Zero is an AI-native CRM for startups that comes with the selling work built in - sourcing, outreach, enrichment and record-keeping run by agents on one complete customer record. If you want a blank canvas and have someone to configure it, Attio is the stronger pick. If you want a five-person team to sell like fifty without hiring RevOps, Zero is built for that. The rest of this page is the detail, including where Attio wins.

How we wrote this

We build Zero, so read this as a competitor's comparison. To keep it useful we follow three rules on every page on /compare: we name where the other product is better, we re-verify prices monthly (Attio prices below checked Aug 21, 2026), and a real person signs it. If something here is out of date, email me and I'll fix it.

The short version

The feature lists look similar on the surface - both have contacts, companies, deals, email sync, enrichment, sequences and "AI." The difference is what each product is for.

Attio is a system of record: a well-designed database with objects, attributes, views and an API, and you (or your RevOps person) decide what it becomes. That flexibility is real and it's why larger teams like it.

Zero is a system of action: an opinionated product for people who sell. There's a full CRM underneath - complete customer record, contacts, emails, pipeline, a 20M+ company database - and that's exactly why the agents can do the work instead of just describing it. You don't design the CRM. You start selling, and the record keeps itself.

One more difference worth naming up front: Attio out-markets us. Bigger budget, louder brand, more of the internet talking about them. That's a real advantage and we won't pretend otherwise. We'd rather win the product comparison - which is what the rest of this page is about.

Background: two different starting points

Attio started life as Fundstack, a CRM for venture capital firms in 2017, before the founders rebuilt it as a horizontal CRM from late 2019 and launched publicly in 2023. It's a mature product with a large ecosystem and it now describes itself as AI-native.

Zero was started in 2024 by a team that had just left a Salesforce-run sales org and tried the new-generation CRMs first - including Attio. We liked its design, but didn't want to build another database. We wanted the CRM to do the admin and the outreach. That's the product decision everything below follows from: Zero was designed around agents from the first commit, so the agents have the full context and the permissions to act on it.

Neither starting point is a moral win. It just explains why Attio optimizes for configurability and Zero optimizes for work getting done.

Section by section

Data model and customization - Attio for bespoke databases, Zero for sales motions

Attio's object model is the best in this category. Custom objects, custom attributes, relationships between records, list-based workflows, a strong API. If your business has non-standard entities (portfolio companies, properties, cohorts, multi-entity deals) Attio models them cleanly. Objects are tiered though: the Free plan allows up to 3 custom objects and unlimited objects sit on Enterprise.

Zero ships with an opinionated core - contacts, companies, deals, activities - and extends it with custom objects: custom activities with their own schemas, plus custom properties and lists. Model QBRs, site visits, product events or whatever your motion produces, and report on them like anything native. What Zero doesn't try to be is a general-purpose relational database: Attio's object model is deeper if that's what you're building, with arbitrary object types and relationships between them.

Verdict: Attio if you're building a bespoke relational database. Zero for custom data that serves a sales motion, with no design phase.

Outreach and sourcing - Zero

This is the biggest practical gap. Attio has sequences and call intelligence on the Pro plan ($79-99 per seat), and the rest of the outbound motion - finding leads, enriching at volume, LinkedIn, a dialer - typically comes from tools around it (Apollo, Clay, a LinkedIn tool, Zapier glue).

Zero has sourcing, multi-channel sequences (email + LinkedIn in one workflow), a dialer, enrichment and intent signals built in, on the same record the pipeline lives on. Agents draft the follow-ups; you approve anything that reaches a customer (how that works: /blog/ai-agents-crm-guardrails).

Response replaced seven tools with Zero and cancelled $7K+/year of software.

Verdict: Zero. Attio plus a stack can match it, but that's the stack Zero exists to replace.

AI and agents - Zero, with a caveat

Both call themselves AI-native. Only one was built that way. Attio launched in 2023 as a customizable database and added AI onto it afterwards - the AI-native label came with the retrofit. AI added to a finished product inherits that product's shape: Attio's AI operates whatever you've configured in Attio, and anything living in Apollo, your inbox tool or a spreadsheet is out of view. Reviewers also note that the AI marketing runs ahead of the depth in day-to-day workflows.

An agent is only as good as the context it can see. Zero's agents run on the whole relationship - emails, meetings, enrichment, pipeline, product and billing signals - because all of it is in one record. That's why they can do record-keeping autonomously and draft outreach that reads like it knows the account.

Verdict: Zero for agents that do the work.

Pricing - depends on team size

Attio (checked Aug 21, 2026): Free up to 3 seats; Plus $35/seat/month annual ($44 monthly); Pro $79/seat/month annual ($99 monthly); Enterprise custom. Sequences and call intelligence start at Pro. On top of seats, usage runs on credits: Plus includes 500 seat credits and 1,500 workspace credits per month, Pro 1,000 and 10,000. Extra workspace credits are $70-85 for 5,000 up to $475-595 for 50,000 a month. Reviewers describe hitting the credit ceiling mid-month when lead volume spikes. If you run real outbound volume, budget for Pro plus credits plus the tools around it.

Zero's pricing is published on Sept 15, 2026 and we'll update this page the same day. The structure is flat per-seat with sourcing, enrichment, outreach and agents included - no separate credit line for the core workflow. Pantera reports Zero is 4x cheaper than the legacy CRM tiers they were on.

Verdict: Attio's free tier is hard to beat for a small team pre-pipeline. Once you're running outbound and inbound, compare Zero's all-in price to Attio Pro + credits + Apollo/Clay, not to Attio alone.

Setup speed - Zero

Attio's flexibility has a setup cost. You design objects, attributes, views and workflows, and most teams with a good Attio setup had a RevOps or GTM engineering person build it. Zero starts more opinionated: connect email and calendar, import or source your first leads, and the record fills itself. Pantera reached full team adoption in two weeks; Atlas in two days.

Verdict: Zero for speed to a working pipeline. Attio if you want to design the system and have someone to do it.

Reporting - Zero for revenue, Attio for custom objects

Attio's advanced reporting sits on Pro and above, and third-party reviews call it basic below Enterprise. Zero reports across the whole record: deals, companies, contacts, stage history, activities (emails, meetings, tasks, LinkedIn touches, custom events), plus connected product analytics, support issues and Stripe billing data. Metrics run from deal value and weighted pipeline to conversion rates, time in stage and MRR/ARR, broken down by time, stage, owner, region, industry, company size or any custom field, on KPI, bar, line and pie dashboards. The numbers also hold up, because agents keep the record current. Zero's custom activities and schemas are reportable like native objects; Attio's remaining edge is reporting across a bespoke relational model.

Verdict: Zero for pipeline-to-revenue reporting on one record, including product and billing data. Attio if your reporting follows a bespoke relational model.

Where Attio is the better choice

• You're building a bespoke relational database: arbitrary object types with relationships between them, beyond what a sales motion produces. Zero's custom objects cover the sales motion; Attio's model goes further.

• You already run a best-of-breed stack you're happy with and want a clean database in the middle of it.

• You want the larger ecosystem and the longer track record: more integrations, more third-party guides and talent who know the tool. Zero is younger on all of those.

• You want the better-known brand. Attio markets more and louder than we do, and name recognition has real value when you're selling a tool internally or hiring people who already know it.

• You want full auto-send. Zero's agents keep anything customer-facing behind approval, by design.

• Your motion is relationship-only with no outbound - you'd be paying Zero for sourcing and sequences you won't use.

• You need pricing you can read today. Zero's is published Sept 15, 2026; until then you're taking our word for the structure.

Where Zero is the better choice

• You want sourcing, enrichment and multi-channel outreach in the CRM, not synced into it from three other tools.

• You want the record to keep itself, with no logging in to do admin.

• You want agents with the whole relationship in view - emails, meetings, enrichment, product and billing signals - not just the objects you configured.

• You want a working pipeline in days, without hiring RevOps to design the system first.

• You report on revenue: weighted pipeline, conversion rates and MRR/ARR next to product and billing data.

Recap

FAQ

Is Zero cheaper than Attio?

For a 2-3 seat team with no outbound, Attio's free plan wins. For a team running outbound, compare Zero's all-in price (published Sept 15) to Attio Pro at $79-99 per seat plus credits plus the sourcing and outreach tools around it. That's where Zero usually comes out ahead.

Can Zero replace Attio + Apollo?

That's the typical switch. Zero includes a 20M+ company database, enrichment and multi-channel sequences on the same record as the pipeline, so the Apollo-to-CRM sync and the second schema go away. Response went from seven tools to one.

Does Zero have custom objects?

Yes. Custom activities with their own schemas, plus custom properties, on top of contacts, companies and deals - all of it reportable like native objects. That covers what a B2B sales motion produces. Attio's model goes further if you're building a bespoke relational database with arbitrary object types and relationships between them.

Is Zero a CRM?

Yes. Zero includes a full CRM underneath - contacts, emails, pipeline, and a 20M+ company database - and that complete record is why the agents actually work. Zero replaces your CRM and the point solutions around it: an AI-native CRM for startups with outreach, enrichment and agents built in.

Can I migrate from Attio to Zero?

Yes. Export from Attio or connect it directly, and Zero's agents map and dedupe the import.
