Dr. Dulan Dias

I build AI products, and the companies around them.

I started a software company from a university boarding room, scaled it past 60 people, and exited it, while earning a PhD in AI at Queen’s University Belfast, building algorithms that help hospitals decide when a patient is ready to go home.

I still spend most of my week in production code: right now as co-founder and CTO of Tellme AI, where we are building Troopa, an AI teammate that takes part in your meetings as they happen. I am also the author of From Model to Product.

I never stopped being the engineer

Most founders stop writing code somewhere around the second hire. I did not, and it is the reason I can tell you why the battery drain on a five-year-old Android decided our inference architecture, or why a museum kiosk has to know its own opening hours.

Now · Tellme AI · 2025–

From a gallery floor to the meeting room

Tellme started as an AI guide for museums: point your phone at an object and ask it anything, with a self-service kiosk that sells access unattended. I designed the architecture and built much of it myself, from the mobile web app to the kiosks in the field.

Now we are taking what we learned into meetings. Troopa is an AI teammate that takes part in your calls instead of just taking notes: ask it something mid-meeting and the answer is on screen while you are still talking, it builds the board as people plan, and it writes the notes when you hang up. More gets done in the meeting, and less after it.

Role
Co-founder and Chief Technology Officer since June 2026; founding engineer, then CTO, before that
Building
Troopa, for Microsoft Teams, Zoom and Google Meet
Where it started
Thinktank Birmingham, National Museum Cardiff and the National Roman Legion Museum

A boarding room to an exit

Bootstrapped into Sri Lanka’s go-to insurtech provider, and stayed hands-on the whole way: InsurEL, PropEL, Legify.ai, and the digital platforms for LOLC and Janashakthi were systems I architected and built, not ones I signed off.

Algorithms for discharge decisions

My PhD in Artificial Intelligence and Data Science produced novel algorithms for AI-driven inpatient discharge decisions: when a patient is ready to go home, and how long a stay is likely to be. The work was published at HIMS’24 and FTC 2024, alongside a longer thread on Sinhala, a language most of the field skips.

The book · 2026

From Model to Product

Foundations for Practical AI Engineering

Most AI content stops at models. Real systems don’t. This book is about everything that comes after: architecture, pipelines, deployment, and making AI work in production for real users.
