Kaizan raises £2.5M seed led by Pembroke VCT to scale AI platform for client-service teams
May 11, 2026
Kaizan, the London-based AI platform for enterprise client-service teams, has raised up to £2.5M in a seed round led by Pembroke VCT, with Velocity Capital and industry angels also participating.
Client relationships generate the bulk of recurring revenue for service-led businesses, yet the signals that show whether those relationships are healthy — sentiment shifts in emails, gaps between meetings, escalations buried in chat threads — sit scattered across systems that account managers rarely have time to read in full. The signal is there; the surfacing isn't.
Kaizan ingests communications and account data and produces a unified view of client health. AI agents built on the platform flag dissatisfaction, recommend next actions and identify upsell opportunities. Published case studies cite time savings of more than five hours per account manager per week and a lift of over 20% in average revenue per client. The product handles communications in more than 30 languages and is deployed across the UK, US, Europe, the Middle East and Asia-Pacific. Named customers include Gravity Global, Tradedoubler and The Gap Partnership.
The company was founded in 2021 by Glen Calvert (CEO) and Pravin Paratey (CTO), who previously worked together on ad-tech startup Affectv. Calvert's earlier ventures include Struq; Paratey was an engineering manager at Facebook on its advertising products and led engineering at UK energy company OVO. Kaizan now employs around 20 people and has raised more than £3M in total, with earlier backers including Founders Factory, Charlotte Street Capital, Love Ventures and Repeat Ventures.
Pembroke VCT, a c.£255M fund managed by Pembroke Investment Managers, contributed the bulk of the round at £1.5M. The new capital will fund US expansion and further development of the platform's AI capabilities, with Pembroke positioning the investment as backing for Kaizan's push beyond the UK and into a global CRM market projected to reach $163B by 2030.
