He adds: “When Workday came to market 20 years ago, one of the big differentiations was our UI UX. People came to Workday because they were tired of the antiquated UI UX experiences on prior HCM financial platforms.

Over the last few years, our UI UX and the innovation around it have moderated, so we see this as an opportunity to completely revamp the user interface for Workday.”Over the last few years, our UI UX and the innovation around it have moderated, so we see this as an opportunity to completely revamp the user interface for Workday.”

Speaking exclusively to UNLEASH, Workleap’s CEO and Co-Founder Simon De Baene says: “For our customers, this unlocks the power of performance data to drive smarter, more consistent compensation decisions.

Torch CEO Heather Conklin also told UNLEASH that when coaching is done right, it “isn’t a perk", but rather a “strategic lever."

She adds: “This acquisition represents our belief that the next frontier isn’t choosing between human connection and AI capability. It’s about creating something even greater by bringing the best of both worlds together.”

Speaking exclusively to UNLEASH, Atlassian Head of Product, Sanchan Saxena, says: “Work has changed. Many of the apps that knowledge workers use have moved to SaaS.

SAP acquires SmartRecruiters

SAP first announced its intention to acquire SmartRecruiters in August 2025, confirming the completion of the deal in October.

SmartRecruiters CEO Rebecca Carr describes this as a way in which the businesses are “not just responding to the future of work”, but “building it.”

Since the acquisition, SmartRecruiters has still retained much of its independence by continuing to work with companies using non-SAP third party technology.

Additionally, Carr, who describes herself as a “people-centric leader” insisted that the deal could only take place if the entire SmartRecruiters was coming, too.

She told UNLEASH, SAP “did not want to let go of one person in our company – no-one has been and will be eliminated”.

BrightHire bought by Zoom

Over the past few years, Zoom has acquired a number of companies, including Bonsai and Workvivo, and in 2025, the business added BrightHire to its portfolio.

BrightHire Co-Founder & CEO Benjamin Sesser wrote in a blog that Zoom and BrightHire are “combining the best in hiring, communication, and workplace AI to transform how the world hires."

He added that this marks an “exciting new chapter” for the business – one that accelerates the business’s “mission to give everyone the hiring experience they deserve, backed by Zoom’s scale, resources, and world-class technology."

UKG buys Mo

Last month, London-based technology innovator Mo was acquired by technology giant UKG in a bid to bring the "power of recognition to more organizations and people than ever before."

As part of the UKG Beacon solution, Mo is now integrated with UKG Ready's comprehensive workforce data to deliver intelligent, data-driven employee engagement for small and mid-sized organizations.

“More broadly, this acquisition reflects what employers want from HR technology platforms,” Russell Howe, Group Vice President, EMEA at UKG told UNLEASH.

Businesses are looking for fewer, powerful tools that use AI to deliver more connected employee experiences.”Businesses are looking for fewer, powerful tools that use AI to deliver more connected employee experiences.”

Findem's acquisition of Getro

Before 2025 draws to a close, Findem - an AI talent acquisition and management specialist - was able to announce its acquisition of Getro - a job network used by more than 800 venture capital, private equity, economic development, chamber of commerce and professional networks globally.

Through the deal, the company will launch its Intelligent Job Posts – turning passive job listings into autonomous AI agents that aim to deliver hiring-ready candidates to organizations.

What's more, Hari Kolam, Findem CEO and Co-Founder, told UNLEASH that Getro was “the missing piece” that will allow the organization to “bring trusted networks and agentic AI together.”

“They’ve built one of the strongest relationship-driven talent networks in the market, and we’ve built the intelligence that understands who will truly thrive in a role, not just who checks the boxes,” he concludes.
