About Diploria

Built for the biggest shift
in search since Google.

Two decades of digital agency experience told us something was changing. We built Diploria to prove it, and to help every agency keep their clients ahead of it.

Built by Reef Digital

A Sydney agency. A global problem.

Reef Digital is an award-winning digital agency based in Sydney, with clients across Australia, New Zealand, the UK and the US. For over a decade, we've built digital strategies for brands that want to be found: on Google, in social, and now in AI.

Diploria is our response to the biggest shift in search since Google launched. We initially built it for ourselves, and we're now sharing it with every agency and brand facing the same challenges we did.

From the founder

We have spent nearly 20 years in digital marketing, helping brands improve their visibility with SEO, and nothing in that time has moved the ground like AI. This is the biggest shift since Google, and it gives our whole industry a rare chance to rebuild itself around one of the most important innovations we will see in our lifetime. Staying on top of it is not optional, for us or for our clients, and the goal is not just to embrace AI but to learn how to master it.

That is why we built Diploria. It helps clients understand the new landscape: whether AI and search engines actually know them, how they are described and whether that sentiment is positive, how their competitors are showing up, and exactly what to change on their side to improve their visibility, mention rate and share of voice. We are just getting started, and excited to see what the future holds.

The meaning behind our name

Diploria is the scientific name for brain coral, one of the slowest-growing yet most enduring structures on the reef. What makes it remarkable isn't just its strength, but how that strength is built: a partnership of countless tiny organisms working in concert, each contributing something small that together becomes one of the largest living structures on Earth.

That idea sits at the heart of how we work. Real growth comes from collaboration, layer by layer, until your brand is simply part of the answer. The name is a nod to our roots at Reef, and to the belief that the strongest things are the ones we build in partnership, made to last.

What we believe

Principles we don't compromise on

Real data, always

We poll live AI APIs, never estimate or model. If we can't measure it accurately, we don't show it.

Agencies first

Diploria is designed around agency workflows. If it doesn't make agencies more efficient, it doesn't ship.

Radical transparency

We tell clients what they don't want to hear. AI visibility is complex; we make it clear, not comforting.

Move with the engines

AI search changes weekly. Our team monitors every engine update and adapts the platform accordingly.

Built to last

We're a bootstrapped agency product, not VC-funded growth-hacking. Sustainable, profitable, and here for the long term.

The founders

Meet the people behind Diploria AI

Diploria was built by the founders of Reef Digital Agency: two practitioners who spent two decades managing digital visibility for brands, and who decided to build the measurement tool they wished existed when their clients started asking about AI.

Hadrien Brassens

Co-founder & Director

Since 2012, Hadrien has been focused on growing Reef Digital into one of Australia's most respected independent digital agencies. With strong channel expertise, he has led digital strategies for brands across Australia, New Zealand, Singapore, the UK, and the US. When clients started asking whether they were showing up in ChatGPT and other LLMs, Hadrien saw a measurement gap that no existing tool could fill without breaking the bank, and started building Diploria as the perfect solution.

Chris Redshaw

Co-founder

Chris brings deep expertise in SEO, Content Marketing, Paid Media and Digital Analytics from more than a decade at Reef Digital. He has managed digital strategies for some of Australia's largest brands, always with a focus on what's actually measurable. Chris has focused on giving Reef's clients a clear, data-driven answer to the AI visibility question, supporting the development of Diploria AI to what it has become today.
