Apollo.io Agency: 9 Best Apollo Experts Compared (2026)

An Apollo.io agency is a firm that sets up and runs Apollo.io for your outbound: ICP filters, enrichment, sequences, deliverability and the sync back to your CRM. Apollo gives a small team a contact database and a sequencer in one tool, so it is easy to start and easy to misuse. Most Apollo accounts that stop producing meetings fail on the same things: duplicate data, generic sequences and replies that never reach the CRM.

This guide compares 9 Apollo.io agencies and experts in 2026, built from Apollo's Certified Partners directory and each firm's own site, all checked on 2026-10-21. It covers what each firm actually does with Apollo, published prices, and a framework to choose.

Disclosure: AY Automate wrote this guide and ranks itself first. Our reason is scope: we use Apollo as one data source inside a larger outbound system (signals, Clay enrichment, Instantly and HeyReach, CRM logging), built and run by one team. AY Automate is not in Apollo's Certified Partners directory. If you want an Apollo-centric certified firm, a packaged HubSpot rollout or fully managed cold email, another agency below fits better, and we say which.

Best Apollo.io agencies: a brief overview

• AY Automate: Best overall Apollo.io agency for automation-first teams: Apollo plus Clay enrichment, buying signals and multichannel outbound in one system.
• GTM Works: Best for Apollo-centric stacks: a certified Apollo partner building AI-driven outbound on Apollo, with LinkedIn tools wired in.
• Orchestra: Best for GTM strategy: the firm behind the Unified GTM methodology Apollo adopted internally.
• SmartBug Media: Best for a packaged Apollo and HubSpot rollout, with published pricing from $4,000.
• Growth Operations Firm: Best for connecting Apollo and HubSpot cleanly.
• FullFunnel: Best for fixing an existing Apollo setup: dedupe, sequences and CRM writeback.
• Blue Frog: Best for HubSpot shops adding Apollo for outbound.
• Proven Concept: Best for fully managed cold email run on Apollo, Clay and Make.
• IGN1TE: Best for non-SaaS verticals like hospitality and retail.

Quick takeaways

• Apollo's Certified Partners directory listed 47 firms on 2026-10-21, with three marked Featured: GTM Works, Blue Frog and Growth Operations Firm. Apollo does not assign tiers.
• Orchestra has the most directory reviews (10) and says it authored the Unified GTM methodology Apollo adopted company-wide.
• Only two agencies here publish an Apollo-related price: SmartBug Media's accelerator from $4,000 and Proven Concept's managed cold email from £3,000 / $4,000 a month.

1. AY Automate, best overall Apollo.io agency for automation-first teams

AY Automate is an AI automation agency that builds outbound and GTM systems. We treat Apollo as one input, not the whole stack. Apollo is good at broad contact search and basic sequences; on its own it does not tell you who is in market this week, and its data still needs checking before it reaches a mailbox. Our Clay and Apollo enrichment agency service combines Apollo with Clay waterfalls, buying signals and verification, then sends through Instantly and HeyReach and logs every reply in your CRM.

The pattern we build most often is the signal-based outbound workflow: a buying signal triggers enrichment, the contact is verified, and the first line of the email references the signal. The broader stack (Apollo for search, signals, website visitor identification, LinkedIn and CRM) is laid out in our GTM automation workflow.

Key features

• Apollo search and export combined with Clay enrichment and email verification
• Signal triggers (job changes, hiring, site visits) that decide who gets contacted
• Sending through Instantly and HeyReach, with domains and mailboxes set up for deliverability
• Replies and meetings written back to HubSpot, Pipedrive or Attio
• n8n jobs that dedupe, route and report (custom n8n automation)
• Option to place an embedded GTM engineer through hire a GTM engineer

Best for

• B2B SaaS and service companies that want outbound tied to buying signals
• Teams already paying for Apollo who want better data and CRM writeback
• Founders who want one team to build and run the system

Pricing

• Custom quote after a discovery call
• Embedded GTM engineer placement from $60,000 a year, with a 90-day replacement guarantee

Pros

• One team for data, signals, sending and CRM logging
• We run Instantly, HeyReach, Unipile, Attio and n8n for our own outbound
• Not tied to Apollo: if another data source fits better, we use it

Cons

• Not an Apollo Certified Partner
• Not the cheapest route if you only need Apollo sequences switched on

How we ranked these Apollo.io agencies

We started from Apollo's Certified Partners directory and each firm's own website, checked on 2026-10-21. We kept only firms whose site explicitly mentions Apollo.io work, and dropped two listed firms whose homepages do not mention Apollo. We then compared scope (setup, managed campaigns or strategy), published pricing, directory and Clutch reviews where they exist, and the buyer each firm fits. AY Automate ranks first on scope, not on Apollo certification, which it does not have.

How to choose the best Apollo.io agency

1) Setup, repair or managed campaigns?

Agencies sell three different things under the same label. Decide which you are buying before the first call.

• New setup: SmartBug Media, Growth Operations Firm or AY Automate
• Repair an existing account: FullFunnel
• Campaigns run for you: Proven Concept or AY Automate

2) Is Apollo your only data source?

Apollo covers a lot of contacts, but match rates and accuracy vary by market. Teams with a narrow ICP usually add a second source and a verification step.

• Apollo only: GTM Works or IGN1TE
• Apollo plus Clay waterfalls and verification: AY Automate or Proven Concept (see our Clay agencies comparison)

3) Which CRM do replies go to?

An Apollo build that does not write back to the CRM leaves your reps working from two systems.

• HubSpot: SmartBug Media, Growth Operations Firm or Blue Frog
• HubSpot, Pipedrive, Attio or Salesforce with custom logic: AY Automate or FullFunnel

4) Do you need strategy first?

If sales and marketing disagree on who the target account is, more sequences will not help.

• Strategy and operating model: Orchestra
• A system built on a strategy you already have: AY Automate or GTM Works

If email is your main channel, our cold email agencies guide compares managed outbound firms, and the LinkedIn outreach agencies comparison covers the LinkedIn side. For the wider build, see the GTM engineering agencies roundup. When you want Apollo, Clay and your sending tools working as one system, talk to AY Automate about your outbound build.

FAQ

What is an Apollo.io agency?

An Apollo.io agency is a firm that sets up, fixes or runs Apollo.io for other companies: ICP filters, enrichment, sequences, deliverability and CRM sync. Some only configure the tool, while others run outbound campaigns on it for you. Ask which of those you are paying for.

What is an Apollo Certified Partner?

It is a firm listed in Apollo's Certified Partners directory at apollo.io/certified-partners. The directory had 47 listings on 2026-10-21. Apollo does not assign tiers, and the descriptions on each profile are written by the partners themselves.

How much does an Apollo.io agency cost?

Published prices on this list start at $4,000 for SmartBug Media's Apollo and HubSpot accelerator, while Proven Concept's managed cold email starts at £3,000 / $4,000 a month. Most other firms quote after a discovery call. Your own Apollo subscription and sending infrastructure are extra.

Should I hire an agency or set up Apollo myself?

You can set up Apollo yourself if you have a clear ICP, a few hundred target accounts and someone who will own deliverability. Hire an agency when replies are not reaching the CRM, bounce rates climb, or you want signals and enrichment beyond Apollo's own data.

Apollo.io or Clay: which should an agency use?

They do different jobs. Apollo is a contact database with a sequencer; Clay is an enrichment and workflow tool that pulls from many providers, Apollo included. Many outbound systems use both: Apollo to find contacts and Clay to enrich and verify them.

Does Apollo.io integrate with HubSpot and Salesforce?

Yes, Apollo has native integrations with both. The common problems are duplicate records and activity logging rules, which is why several agencies on this list specialise in the HubSpot connection.

Can an Apollo agency also run LinkedIn outreach?

Some can. GTM Works integrates Apollo with HeyReach, and AY Automate runs LinkedIn outreach on HeyReach and Unipile next to email. If LinkedIn is your main channel, an AI automation agency for RevOps or a dedicated LinkedIn firm is worth comparing.
