About us
How Definia dares to be different
Definia is the consulting arm of The IN Group, a collective of six award-winning brands. While our sister companies, such as Investigo, connect organisations with exceptional talent, we bring the capability to deliver transformation, not just hire for it.
We partner with clients who need structured change support — whether that’s digital delivery, operating model redesign or large-scale programme leadership. As part of The IN Group, we have the unique ability to build the right team around your transformation, drawing on specialist recruitment expertise when needed, whilst remaining focused on delivery.
It’s a powerful combination: consulting expertise that helps you achieve lasting change, with the backing to access the talent that makes it happen.
“Why reinvent the wheel when your existing resources can be enabled to succeed at an elite level? At Definia, we measure change against outcomes – so you only get what you need, when and how you need it.” – Rachael Hays, Director at Definia
Our methodology
Our expert teams bring transformations to life, via our core specialist service areas: Capability-as-Service (Caas), CaaS+, program delivery and advisory services.
Whether it’s maximising investment in the right digital technology, creating dynamic operating models or adopting new ways of working, we keep organisations relevant, resilient and ready for tomorrow.
How do we do this?
Definia works on each project in four simple steps, keeping our clients at the heart of what we do.
- Define the challenge to gain clarity on your maturity and opportunities
- Design the best strategies and solutions for your unique business, creating a practical roadmap to reach your future state
- Deliver sustainable change with confidence, controlling risk and delivering outcomes
- Drive real success beyond go-live, sustaining value in the long term
Following this methodology, we create targeted strategies designed specifically to find advantage and elevate overall business performance.
What sets us apart?
We believe transformation should be a journey walked side by side. Our vision is to help organisations reimagine and realise technology-enabled change, working collaboratively to unlock real outcomes, not just PowerPoint promises.
By combining clarity of purpose with a commitment to delivery, we ensure that transformation is not only bold and ambitious, but also practical, achievable and uncompromised.
Our purpose is to deliver transformation outcomes that succeed sustainably and empower clients long after we leave. With Definia by your side, tomorrow is an exciting space to explore, adapt and succeed.
