RE:STACK!, one of the fastest-growing Bullhorn consultancies in the market, and Exenai, the automation and candidate-experience specialist built exclusively for Bullhorn, today announced a strategic partnership to help agencies go further with the native Bullhorn stack—while unlocking the integrations, apps, and intelligent automations needed to modernise operations end-to-end.

RE:STACK! brings deep Bullhorn optimisation, RecOps transformation, and high-impact enablement and training. Exenai adds a fully managed “Automation as a Service” operating layer—combining API integrations, Digital Workers (RPA), embedded apps, and AI-powered data transformation—to extend Bullhorn where point-to-point integrations stop. Together, clients get faster time-to-value, cleaner data, and measurable ROI across the entire recruitment lifecycle.

“Both teams chose to be Bullhorn-only for a reason,” said Richard Harrison, CEO & Co-founder, Exenai. “This partnership gives customers a single, high-calibre path: optimise Bullhorn to its best with RE:STACK!, then extend it with Exenai’s intelligent automation layer to connect systems, remove admin, and scale with confidence.”

“Our clients want outcomes, not more tools,” said Holly Langley, Founder & CEO, RE:STACK!. “We specialise in making Bullhorn pay for itself through smarter processes, adoption, and automation. Pairing that with Exenai’s managed automation and apps means we can deliver bigger wins, faster - without adding complexity.”

“This is about an intelligent, connected operating layer for recruiters,” added Alex Lea, Co-founder & CTO, Exenai. “Bullhorn remains the core system of record; we orchestrate everything around it - securely enriching data in-flight and delivering embedded experiences that feel native.”

Why this partnership matters

Bullhorn-first, by design. Both firms operate exclusively in the Bullhorn ecosystem—maximising what’s native, then extending it thoughtfully where needed.
From enablement to execution. RE:STACK!’s audits, roadmaps, and training align teams and processes; Exenai implements and runs the automation layer as a managed service.
Measurable ROI. Clients benefit from streamlined workflows, reduced manual work, cleaner data, and faster decisions—driving placements and profit. (Examples and results available on request.)
Proven Bullhorn leadership. Exenai’s founders previously built Invenias (acquired by Bullhorn) and led Bullhorn product/engineering; RE:STACK! is led by a seasoned RecOps operator focused on Bullhorn value realisation.

What clients can expect

Bullhorn optimisation & RecOps transformation (RE:STACK!): full audits, adoption programmes, and hands-on coaching that make Bullhorn the high-performing centre of your stack.
Automation as a Service (Exenai): API integrations, RPA/Digital Workers, embedded apps, and AI-powered data mapping that securely transform and enrich data between Bullhorn and adjacent systems.
Candidate Experience Platform (Exenai): branded, consumer-grade experiences that capture candidate-validated profiles and reduce admin—fully aligned to Bullhorn schema.
