Does O4 do anything more than rent out space?
Yes. Rental is only one part of our operations. O4 is also a producer and organiser of original business projects – such as conferences, development programmes, workshops, and networking initiatives. A prime example is LEADWELL – a conference created by O4 for team leaders across various industries.
Where do ideas for projects like LEADWELL come from?
Our projects stem from:
- Conversations with leaders and companies,
- Observations of real-world challenges (people management, wellbeing, AI, organisational culture),
- The needs of the O4 and Olivia Centre communities.
- Every project has a clearly defined business and development goal. It is a response to a specific problem – not just a format for the sake of it.
Where can I find information about projects like LEADWELL?
