A vibrant, connected and right-sized enterprise formed by specialist delivery professionals, offering full-stack strategic planning, analytics and optimisation for large organisations.

Our story

Where we came from

TwentyThreeHundred was originally formed to provide specialist products and services in support of major HM Government transformation programmes. Created by like-minded specialist delivery professionals from the world of P3M, we have grown into a vibrant, connected and right-sized enterprise.

Since 2018, we have helped our customers deliver major IT change initiatives; formed the specialist core of PMO, CoE and Product Operations functions; helped PPM organisations move towards becoming successful Product Organisations; and planned organisation-wide migration to Cloud Services.

Our team comprises delivery-oriented professionals with experience of management, delivery, change and consultancy, across P3M, product and operational contexts. Led by senior consultants, our multidisciplinary team brings together extensive knowledge from various sectors.

We develop specialised solutions that incorporate best practices and the latest technologies, tailored to address local contexts and delivery challenges.

We develop specialised solutions that incorporate best practices and the latest technologies, tailored to address local contexts and delivery challenges.

Deep domain knowledge

Our senior consultants bring 10 to 25 years of industry expertise across P3M, product and operational contexts, with genuine experience at the heart of HM Government delivery.
