Bullhorn Amplify vs. HeyMilo: AI Differences For High-Volume Hiring

Bullhorn entering the AI race with Bullhorn Amplify has brought more attention to how teams think about AI in staffing. More leaders are trying to understand where it fits in their recruitment lifecycle, how it compares to traditional Bullhorn ATS & CRM functionality, and whether Amplify changes how they should structure their tech stack moving forward.

This blog is a practical comparison between:

Bullhorn Amplify = AI built inside the Bullhorn ATS

HeyMilo = an external, end-to-end AI recruiting engine across the entire hiring workflow

Two different tools, with two different scopes. Let’s compare!

‍

What Bullhorn Amplify Actually Is

Bullhorn Amplify is Bullhorn’s own AI recruitment software, built natively in Bullhorn ATS & CRM and Bullhorn Recruitment Cloud. It was launched to help recruiters automate matching, screening, enrichment, and outreach.

If you’re asking “Is Bullhorn an ATS?” the answer is still yes, but Amplify turns it into an AI-powered operating system.

Amplify offers four core AI assistants:

1. Match: AI-driven relevancy scores

Amplify can be used to automatically surface top-fit candidates when a job hits the ATS.

It uses AI-powered skills extraction, predictive analytics, and matching signals to analyze the candidate record and job descriptions.

2. Screen: AI candidate screening questions + real-time conversation flow

Amplify Screening automates initial screenings with:

• structured interviews (chat-based, voice available)
• screener engagement steps
• recruiter-ready summaries
• screening dashboards
• screening score + status

Built to reduce manual effort during the initial qualification phase.

3. Enrich: Cleaner CRM data

Amplify can:

• enrich profiles using generative AI
• auto-fill contact details, addresses, and work history
• create structured summaries of candidate skills
• enhance public job descriptions and job posts

Over time, this helps reduce CRM decay.

4. Outreach: automated, personalized messages

Amplify assists with nurture campaigns, follow-ups, reminders, and candidate engagement workflows.

Who It’s Built For

Agencies who run entirely on Bullhorn ATS & CRM and want a basic AI layer without adding standalone systems.

Where Bullhorn Amplify Fits in the Recruitment Lifecycle

Amplify aims to strengthen four areas:

• candidate matching
• initial screenings
• candidate profiles + data enrichment
• automated outreach and recruiter workflows

The tools are especially useful for teams who rely heavily on Bullhorn automations or want Bullhorn Automation Amplify Edition to streamline day-to-day administrative tasks.

If your team is evaluating Bullhorn ATS pricing or comparing ATS tools, Amplify gives Bullhorn a more modern edge, especially compared to older, non-AI ATS systems.

‍

Where HeyMilo Fits and Why It’s Different

HeyMilo on the other hand, is not tied to a single ATS.

It’s meant to sit on top of major platforms like Bullhorn, JobDiva, Avionté, Greenhouse, Salesforce, Lever, Teamtailor, Ashby, Manatal and many more.

It’s in a completely different category:

HeyMilo = an end-to-end AI recruiter that automates sourcing → engagement → screening → evaluation

Where Amplify enhances Bullhorn workflows, HeyMilo automates the entire recruiting lifecycle across multiple systems, job boards, and communication channels.

HeyMilo handles:

• sourcing across internal & external databases
• personalized SMS, WhatsApp, email engagement automations
• contextual resume screening beyond keywords
• SMS screening
• form-based screening
• multilingual, two-way conversational voice-based interviews (video + phone available)
• live, in chat candidate and recruiter support
• cheat detection (facial behavior, phone detection, tab switching)
• autonomous agents that run 24/7 and work together
• comprehensive candidate insights + structured scorecards

For teams, HeyMilo acts less like a simple ATS add-on and more like an AI recruiter layer that sophistically automates and coordinates large portions of the sourcing to qualification process.

Bullhorn Amplify vs. HeyMilo: A Clear Comparison

‍

Why Staffing Firms Use Both

Amplify → cleans data, improves matching, strengthens Bullhorn ATS.

HeyMilo → handles the front half of hiring at scale: sourcing, engagement, screening, interviewing, while strengthening your ATS (not just Bullhorn).

Recruitment firms often combine them when they want:

• stronger top-of-funnel automation
• reduced job board dependence
• automated screening pipelines
• faster time-to-submit
• better submittal-to-hire ratio

Bullhorn ATS stays the system of record, and HeyMilo becomes the autonomous recruiter powering the workflow.

‍

Bullhorn ATS Pricing and Where Amplify Fits Financially

Recruiters search "Bullhorn ATS pricing" constantly because pricing varies by seat, modules, and automations. Amplify is typically an add-on to the Bullhorn Recruitment Cloud.

Teams evaluating price usually compare:

• cost of Amplify
• vs.
• cost of adding more sourcers or coordinators

Amplify offers helpful automation inside Bullhorn, but it isn’t designed for deep candidate-qualification workflows. HeyMilo’s agents are purpose-built for those tasks, which is why they can more deeply support a larger portion of the early funnel.

‍

So… Which Should You Use?

If your entire workflow lives inside Bullhorn ATS & CRM → Amplify is a natural, frictionless upgrade.

If your organization recruits across multiple databases, markets, communication channels, or ATS systems → HeyMilo covers the end-to-end hiring journey in a way Amplify isn’t designed to.

Most high-volume staffing firms will use both:

• Bullhorn ATS as the backbone
• HeyMilo as the AI recruiter powering sourcing, engagement, screening, and interviewing

‍

Final Takeaway

Bullhorn Amplify is a strong start to the evolution of Bullhorn ATS & CRM, an important step in the staffing industry’s shift toward recruitment AI and autonomous agents.

HeyMilo operates at a different scope:

It automates the entire recruitment lifecycle with a suite of smart agents across platforms, databases, and communication channels.

Both are powerful in the right context.

But they aren’t interchangeable, and understanding that is how staffing leaders choose the right AI strategy in 2026.
