Phenom Acquires Plum to Verify What AI Can’t Fake: Human Behavior at Work

PHILADELPHIA, April 28, 2026 — As AI-generated resumes, deepfake interview responses, and fabricated work histories create a new candidate verification crisis for enterprise hiring, Phenom today announced the acquisition of Plum, a pioneer in psychometric-based talent assessments that validate the durable skills AI cannot manufacture and resumes cannot verify. This follows the acquisition of Be Applied, completing a full-spectrum assessment stack that validates cognitive, behavioral, and situational capabilities across every candidate and role at enterprise scale. Phenom's AI agents will turn what used to take weeks into hours, scaling validated behavioral assessments across every open role and cutting the risk of bad hires.

Plum’s proprietary Role Model™ technology maps behavioral blueprints against more than 40,000 real-world jobs, delivering scientifically validated predictions of how candidates will perform in a given role with accuracy proven four times greater than resume screening alone. Combined with Phenom’s agentic delivery and Hypercell context, enterprises can now measure the durable human skills that determine on-the-job success (e.g., empathy, judgment, adaptability, resilience) for any role, in any market, without the manual burden that has historically kept behavioral science out of hiring at scale.

“AI is making general intelligence a commodity, and human skills have never mattered more; yet hiring still relies on gut feelings to assess them,” said Mahe Bayireddi, CEO and co-founder of Phenom. “By bringing Plum’s psychometric science and models together with our skills ontologies and agentic workflows, we’re enabling every enterprise to scale behavioral assessments that predict employee performance for every role, in every market.”

A Verification Layer for AI-Era Hiring

The acquisition comes as enterprise hiring faces pressure on two fronts: the collapse of resumes as a reliable signal for candidate potential, and the inability of legacy assessment tools to scale behavioral insight consistently across roles, markets, and hiring volumes. By 2028, one in four job candidate profiles worldwide will be fake according to Gartner. At the same time, the cost of a single bad hire averages at least 30% of the employee’s first-year salary, before accounting for lost productivity, manager time, and team impact.

The combination of Plum’s science with Phenom’s Hypercell framework and automation capabilities will give enterprises the ability to address the issues of synthetic talent by empowering them to rapidly scale comprehensive skills validation to emerging and transforming roles. Taking into account the full context of each role based on industry, function, and geography, AI and automation will be carefully applied to both assessment creation and delivery. By automating conversations with managers and interactions with employees, AI agents generate behavioral blueprints in hours instead of weeks and make assessments immediately available for automated delivery. Every assessment is independently audited using large-scale candidate data to detect adverse impact across demographic groups, and designed to meet global data privacy and regulatory standards.  

How It Works in Practice

Organizations can define what success looks like for any role and automatically deploy the right assessments to measure candidate fit, calibrated to the specific demands of their industry, function and market.

A healthcare system hiring patient-facing staff can assess empathy and composure under pressure alongside clinical skills, delivered via Phenom’s Voice Assessment Agent so nurses can engage on their own schedule. A financial services firm recruiting relationship managers can evaluate social intelligence and sound judgment alongside technical qualifications, with the Sourcing Agent surfacing the strongest internal and external candidates before the AI Interviewer conducts a dynamic, behavioral-fit conversation. A hospitality company recruiting guest experience managers can assess emotional intelligence, like the ability to read people, while the Simulation Agent tests how candidates handle difficult customers or unexpected situations, augmented by Plum's psychometric science to evaluate behavioral traits across a broader range of interactions.

In every case, the behavioral data does not stop at the offer to help organizations make more precise workforce decisions. Organizations can apply the same intelligence to onboarding, career pathing, and manager coaching, turning the traits that predicted success in a role into the foundation for what each employee grows into next.

“Resume-based screening and basic assessments reveal what candidates have done, but aren’t well-suited for identifying leadership potential, adaptability, and learning agility, especially in an era of poor skill signal quality, rapid technological change, and shortening skills shelf-life,” said Abhinav Shrivastava, Research Manager, Talent Acquisition and Strategy at IDC. “Integrating skills-based assessment with psychometric science delivers a more robust and reliable skill signal. Phenom's acquisition of Plum, in addition to Be Applied, brings comprehensive assessment capabilities to the market, enabling organizations to surface both existing skills and potential, improving hiring accuracy and decision-making.”

Completing the Assessment Stack

Plum joins Be Applied (acquired February 2026) as the anchors of Phenom's strategy to unify candidate assessment and employee development on a single agentic platform, so the behavioral intelligence captured at hire continues to inform growth, mobility, and succession planning across the talent lifecycle. Be Applied provided cognitive and situational judgment assessments, while Plum provides psychometric and behavioral validation. The result: the only end-to-end system for validating candidates on both what they can do and how they’ll do it, driven by Phenom’s Hypercell precision, governed by Phenom WorkOps and delivered through AI agents that operate alongside recruiters and hiring managers.

“Plum was built on the belief that every person has untapped potential, and organizations deserve the science to find it,” Caitlin MacGregor, CEO and co-founder of Plum. “Joining Phenom brings that science to every hiring team, every career decision, and every industry around the world. Performance depends on fit, not pedigree. Together, we’re giving organizations the ability to hire with precision, surface overlooked talent and build teams based on how people actually think and perform.”
