How Recruiters Are Switching from Greenhouse to Atlas—Without Skipping a Beat

Greenhouse works well for many in-house recruitment teams, but for fast-paced UK agencies, it can become limiting. Manual admin starts to stack up, outreach becomes inefficient, and reporting often takes longer than expected. Despite these frustrations, many teams hesitate to make a change because they’re worried about disruption.

That hesitation is understandable. Moving to a new ATS sounds risky if it means downtime, data loss or having to retrain everyone.

But that doesn’t have to be the case.

In this article, we’ll explore how UK agency recruiters are switching from Greenhouse to Atlas while keeping their operations running smoothly. You’ll see how the right migration process, paired with tools designed for agencies, can simplify workflow and improve productivity without putting recruitment on hold.

Why UK agencies consider leaving Greenhouse

Greenhouse is a well-known platform for customers in the ATS space, but it was originally built with in-house tech and startup teams in mind. For UK-based agency recruiters, that foundation can create friction.

Agencies often find themselves working around the system rather than with it to match talent to their clients’ companies. Workflows that should be simple—like moving candidates through stages, client reports, or sending targeted, thoughtful outreach—end up taking more time than they should. Greenhouse offers powerful functionality to its users, but it’s not tailored to the pace and demands of agency environments.

Common reasons recruiters consider switching include:

• Too much manual admin. Everyday tasks like updating candidate statuses, scheduling interviews or managing pipelines often require repetitive clicks or external tools.
• Limited automation. Automating routine processes is difficult without third-party integrations, which adds cost and complexity.
• Lack of business development tools. Greenhouse isn’t built to support proactive outreach or personalised engagement at scale—key activities for agency growth.
• Inflexible reporting. Creating client-ready reports or internal performance snapshots typically involves workarounds or exporting data to spreadsheets.
• Poor UK-specific alignment. Agencies need tools that reflect local compliance standards, billing models, and team structures—areas where Greenhouse often falls short.

These gaps don’t always show up right away. Many teams only notice them as they grow, diversify their client base, or look for ways to improve efficiency. By that point, the platform feels less like a system of support and more like something holding them back.

What a smooth data migration actually looks like

For many agencies, the idea of switching ATS platforms triggers concerns about downtime, data loss, or a painful onboarding process. These are real risks if the migration isn’t handled well. But with the right approach, the transition can be fast, controlled, and disruption-free.

Atlas takes a structured, guided approach to migration that ensures recruiters can continue working without interruption. From the very first planning call to the final sign-off, the process is designed to minimise risk and remove the heavy lifting from your team.

Here’s what that looks like in practice:

• Live access throughout. You’ll continue using your current ATS until the new system is ready to go live. There’s no blackout period or forced switchover.
• Clear data mapping. All key data—candidates, clients, jobs, notes, communications and custom fields—is carefully mapped and migrated to maintain integrity and usability.
• Dedicated support. The Atlas migration team manages the entire project, including sandbox previews, feedback rounds, and post-migration checks.
• Tested, not rushed. You’ll review a sandbox version of your migrated data before anything is finalised, giving your team confidence before the switch.

This process has been developed specifically for recruitment agencies. It removes uncertainty and gives your team a clean, working system from day one—so there’s no need to pause hiring or change how you work during the transition.

What you gain by migrating to Atlas

Migrating to a new platform isn’t just about fixing what’s broken. It’s also an opportunity to raise the bar on how your team works every day. Atlas is designed specifically for agency recruiters, with built-in tools that remove admin, improve reporting, and give you more time to focus on placements and growth.

Here are four key features that make a real difference:

1. Recruiting process automations that eliminate admin

Atlas includes automation tools that reduce the need for repetitive actions, whether you’re a one-person army or an enterprise agency. From automatically updating candidate statuses to triggering reminders and follow-ups, you can streamline everyday workflows without relying on third-party tools.

Whether you’re chasing up interview feedback or updating a job pipeline, rest assured that Atlas handles it behind the scenes—so recruiters can spend more time on high-value work.

2. Executive search reports in a few clicks

Client reporting shouldn’t require a spreadsheet marathon. Atlas lets you generate polished, client-ready search reports in seconds, with insights into candidate pipelines, outreach activity, and project status.

Reports can be tailored to your agency’s or client organisation’s branding and formatted for easy sharing, making it simple to keep clients updated and engaged.

3. Built-in AI note taker

Capturing candidate insights during calls and interviews is vital—but manual note-taking slows everything down. Atlas solves this with an AI note taker that records and summarises your calls into clear, structured notes.

These summaries are saved directly in the candidate record, making them easy to reference later and helping teams share context without extra admin.

4. Personalised outreach at scale

Whether you’re nurturing passive candidates or building your BD pipeline, personalised outreach is essential. Atlas supports multi-channel outreach across email, calls, and to-dos, with smart templates and AI-powered suggestions to improve open and response rates.

Recruiters can run targeted campaigns that feel personal—without spending hours writing from scratch.

The Atlas migration process – What to expect

Atlas has developed a proven migration framework tailored specifically for agency recruiters. It’s structured, collaborative, and designed to keep your team working while the migration happens in the background.

Here’s how the process works:

1. Migration kickoff from your previous ATS

Everything starts with a planning call. You’ll meet the migration team to define your goals, outline what data you want to bring over, and align on timelines. Whether you’re moving from Greenhouse or a combination of tools, the focus is on making the transition clean and controlled.

2. Data mapping

Next, the Atlas team maps your Greenhouse data into the new system. This includes:

• Candidate records
• Job data
• Client/contact details
• Notes and communications
• Custom fields and relationships

If your current setup has workarounds or inconsistencies, Atlas helps clean and restructure your data to fit into a more usable, scalable format.

3. Sandbox import

Before anything goes live, you’ll receive access to a sandbox version of Atlas populated with your real data. This allows you to:

• Preview how records appear
• Test workflows
• Flag anything that needs adjusting

This step is key to avoiding surprises and gives your team confidence in the new setup.

4. Final migration and sign-off

Once you’re happy with the sandbox, Atlas completes the full import and activates your live system. Your team can begin using it immediately, with no need for downtime or dual systems.

5. Post-migration support and onboarding

After go-live, you’ll receive structured onboarding sessions, access to a knowledge base, and responsive support. Your team is guided through key features, workflows, and any custom elements specific to your agency.

Atlas doesn’t just move your data—it helps you move forward.
