A sounding board for the decisions that shape your business. Get clear on who you serve, why they should care and where to focus your time and resources.
Turn an opportunity into a product people have a reason to buy. Challenge assumptions, define the first useful version and decide what to build next—and what can wait.
Experienced leadership for a defined priority, without a full-time appointment. I work alongside you and your team to connect the commercial ambition with the day-to-day work.
I’m Dorian, an entrepreneur and the CEO of Colateral. My experience spans technology, retail media and broadcasting: shaping products, developing commercial opportunities and bringing people together to make things happen.
I bring a commercially minded founder’s perspective, with a practical understanding of what customers will actually buy, built through developing and launching products myself. I help early-stage teams connect that understanding with clear product direction and commercial priorities.
“Would someone buy this?”
A simple question. A useful place to start.
Products and businesses I’ve helped bring to market across broadcasting, local media and retail technology.
I launched a control layer for audience interaction across multiple platforms in live broadcasts. The product was used by the BBC, ITV, Channel 4 and MBC in the Middle East, among others.
Over £6m in product sales after launch.
A practical example of connecting a product proposition with the needs of major broadcasters.
I launched a local internet television business in the UK, then acquired a small publishing business to create a content proposition spanning online video and print.
The aim was to bring complementary channels together around a local audience, extending what the business could offer readers, viewers and advertisers.
As founder and CEO of Colateral, I’ve built a retail technology business connecting store-level information with campaign delivery and retail media.
The acquisition of Turbyne brought complementary retail media planning, selling and execution capabilities into the business, expanding the product proposition.
