Blue John

Blue John makes reputation visible. Founded by a team with over 20 years in reputation management, due diligence and Open Banking, we are building trust infrastructure for enterprise.

The talent system is broken: AI-generated CVs are too perfect, the application tsunami has overwhelmed even the most sophisticated hiring teams, screening checks look backwards, assessments look inwards, and references are still inherently biased and performative. No one has been looking outward at the person. When 1 in 3 hires is a wrong hire and costs an estimated three times salary on average, the impact goes beyond financial cost and hits culture, momentum and reputation.

This is democratisation of talent for the 90% of people that have had no due diligence, but are the actual heart of every organisation.

Our platform, GREY, changes that. Combining applied neuroscience, reputation analysis and AI, GREY delivers People Risk Intelligence providing a structured view of who someone actually is, not just what they claim to be. We surface Grey Flags, Lightning Bolts and the Traitmarks® of a person, adding the layer of insight that interviews and CVs simply can't provide.

"We have been assessing people the same way for too long. It's time to look at who a person really is, not what they claim to be. GREY gives organisations the insight to see the person, not the CV, before a wrong hire becomes a cost that's financial and reputational. We don't provide judgement. We're here to protect your talent system, not replace it."
Lorna Cobbett, Founder and CEO of Blue John

The people risk intelligence GREY provides compounds over time. The same insight that informs a hiring decision shapes onboarding, talent management and leadership development. This isn't a sunk cost, it’s trust infrastructure that builds value with every use.

"We will do for talent data what Open Banking did for financial data. This is about creating opportunities for the many, not the few, while creating a level playing field for talent."
Lorna Cobbett, Founder and CEO of Blue John

By making due diligence accessible across the talent lifecycle, not just for the top 10%, GREY gives every person the chance to be seen for who they really are and every organisation the confidence to hire on insight, not gut.

If you could know, why leave it to chance?
