Custom automation hub

Bullhorn logo

Keep a database this big Bullhorn alive

A custom automation hub that enriches your Bullhorn candidate records at scale from Coresignal and Apollo — current roles, verified contacts, and job-change alerts — so a high-volume agency desk stops working from stale data.

Implementation from €2,500 · Runs on your own keys · Your data stays in Bullhorn

The stack

Three systems, one daily loop

Your ATS stays the source of truth. Coresignal and Apollo keep it honest.

Bullhorn

Your agency system of record

The hub reads and writes back to Bullhorn through its API. The database your whole agency runs on stays the single source of truth — enrichment happens in place, at volume, with nothing exported.

Coresignal

Workforce & firmographic data

Coresignal refreshes current title, employer, tenure, and company headcount across thousands of records, so even the candidates you have not touched in a year reflect where they work today.

Apollo

Verified contact data

Apollo finds and verifies emails and direct dials at scale, so high-volume outreach reaches live contacts instead of burning a desk on bounced sends.

Capabilities

What the integration can do

Everything below runs on a schedule and writes straight back into Bullhorn.

  • Enrich Bullhorn candidate records in bulk from Coresignal and Apollo — no consultant manually working through the database.
  • Detect job changes across the whole database and deliver a ranked daily list of movers worth a redeploy call.
  • Verify and refresh emails and phone numbers at volume, retiring bounced contacts before they hurt deliverability.
  • Backfill missing fields — title, employer, location, LinkedIn, company size — across years of accumulated records.
  • Top up firmographics on company records so business development can target by headcount, industry, and growth.
  • Write every update back into Bullhorn with a source and timestamp per field, keeping a clean audit trail at scale.
  • Run on your own Coresignal and Apollo keys, so the data volume and the spend stay entirely yours.

The payoff

How much time it saves

Conservative estimates. The exact numbers depend on your database size and how stale it has become.

Manual record enrichment

A consultant spends 5–8 minutes per candidate cross-checking LinkedIn, sourcing a number, and updating Bullhorn.

~6 min saved per record — at 60 records a day that is roughly 6 hours back across the desk.

Finding redeploy opportunities

Contractors and placed candidates who become available are easy to miss in a database this size.

A daily ranked list of movers replaces hours of speculative database trawling.

Cleaning a list for a campaign

Scrubbing hundreds or thousands of contacts for valid details before a mailshot is a full day of work.

A pre-verified list ready immediately instead of a day lost to cleanup.

How it works

A hub your team actually uses

Automated where it should be, conversational where you need control.

01

Daily automation

Every morning the hub pulls a batch of Bullhorn candidate and contact records, enriches them through Coresignal and Apollo, and writes the results back — before your team logs in.

02

Automation hub overview

A single dashboard shows what ran, what changed, which records were enriched, and what needs a human eye — full provenance on every update, no black box.

03

A Claude project to engage

A dedicated Claude project sits on top of the enriched data so your team can ask questions, draft outreach to candidates, and trigger enrichment on demand in plain language.
