Wanted to say a big thank you for chairing such an excellent panel at our Sustainability Delivery Summit London 2026. We have had some very positive feedback so far - your panel was cited as a highlight by attendees.
Oliver Cronk, who led the work, has provided outcome-focused practical advice and constructive challenge which has earned the trust of our technology leadership and the architecture team.
He has an extreme growth mindset combined with an encyclopaedic technical knowledge base. He is a true asset to any organisation looking to both innovate and also execute!
He has a unique combination of highly technical knowledge and skills, and strong business acumen, which makes him a rare breed in the products and innovation space (and highly desired).
Oliver is an innovative and pragmatic architect, expertly balancing the divide between technically possible and realistically achievable.
He has excellent communication skills, and is able to change his language appropriately for the audience involved, ensuring that all parties feel involved and comfortable with the decisions that have been made.

The assessment of our AI orchestration platform was especially valuable. He gave us an independent view of the security risks, controls and governance questions involved in agentic AI, written for both technical and business readers, so we understood the trade-offs before going further.
