Rethinking how cognitive change is understood
VBuddies is a Cambridge-based health technology company developing a new approach to personalised cognitive assessment. Our ambition is to move cognitive assessment beyond isolated snapshots towards a more longitudinal understanding of how an individual's cognition changes over time.
From cognitive snapshots to individual trajectories
Cognitive change happens over months and years, yet assessment is often concentrated around individual points in time. Our mission is to enable a more continuous and personalised understanding of cognitive change — helping create the longitudinal intelligence needed for the next generation of cognitive health and care.
We believe understanding the trajectory can be as important as understanding the moment.
Cognitive care needs a longitudinal layer
Existing cognitive assessments provide important information at specific points in time. VBuddies is developing technology designed for repeated, personalised cognitive assessment — creating a longitudinal picture that can complement existing approaches and help health and care organisations better understand individual trajectories.
Conversation can change how we assess cognition
VBuddies is developing a conversational approach to cognitive assessment designed to make repeated participation more natural, personal and scalable. Our proprietary AI technology transforms repeated interactions into personalised cognitive intelligence, building a richer understanding of change over time.
Building the longitudinal intelligence layer for cognitive health
Our long-term vision extends beyond a single assessment. We believe longitudinal cognitive intelligence can help health and care move towards a more personalised understanding of cognitive ageing and individual trajectories — supporting better-informed assessment, monitoring, care and, ultimately, access to emerging interventions. VBuddies is building the technology and evidence base to help make that possible.
