Rational Partners is a technology leadership consultancy working with investors and the businesses they back across the UK and Europe. Our bench of more than 30 experienced CTOs and CPOs provides fractional leadership, technology due diligence, and AI transformation, delivered by people who have held the role, not career consultants. We help leadership teams work out where AI genuinely creates value and embed it across the business, from the boardroom to the engineering floor: this year alone we have trained over 2,000 developers in AI-assisted engineering. Our 5P due diligence framework has been refined across more than a hundred engagements from seed to exit, and every finding is framed in terms investors act on: risk, cost, and value creation. We sell no software, hold no equity, and have no vendor partnerships, so our advice serves one interest: yours
