Talks

Tynan Byrne - Stop Guessing: How to Actually Know Your AI Feature Isn't Useless

You tweaked your AI prompt. Your teammate suggested adding markdown. Your manager wants to try Claude instead of GPT-4. Is it better now? Worse? Nobody actually knows. In this talk, I'll show you how to use an eval loop to iterate on AI features with confidence. We'll take a simple AI tool and improve it live - changing prompts, running tests, and watching scores update in real-time. You'll see which changes actually help and which just look different. Then, I'll show you how we do this at scale at Omnea: hundreds of test cases, continuous experimentation, big AI features used by the likes of Monzo and Spotify. You'll leave knowing how to judge your AI features with data, not just vibes.

Software Engineer at Omnea

N. Nain - Introducing TypeScript into a codebase owned by hardcore C++ / Rust engineers (and the politics involved)

When I joined an indie gaming studio as Lead Engineer to build a new Web Engineering team, I assumed my biggest challenges would be technical - porting and integrating with an existing Rust and C++ codebase. I was only half right - as it turned out the real challenge wasn't the code, but the developers behind it! Tonight, I'm not just gonna talk about the two languages I personally love, but the people - and the artificial tribes that formed around them. The technical challenges and misconceptions. The arguments. The (occasional) shouting. And the stranger-than-fiction lengths people went to, just to prove a point. Funny, tragic, and over the top - but everything works out in the end? Welcome to modern software development at work.

Sponsor: Omnea:

Omnea is a London-based AI-native procurement technology company that builds a platform to streamline how organisations buy goods and services, manage suppliers, and control spend through automated workflows and embedded governance. Founded in 2022 by Ben Freeman and Ben Allen, Omnea replaces slow, manual procurement processes with an intelligent system that lets employees make requests conversationally while routing approvals across finance, legal, IT, and security teams. Since its launch, Omnea has experienced rapid growth, driven by strong enterprise demand for AI-powered procurement solutions. Over the past year the company has grown revenue 5× and more than tripled its headcount, adding high-profile customers across North America and Europe, including Spotify, Albertsons, Wise, Adecco, and MongoDB. Omnea's growth has been supported by significant venture funding, including a $20 million Series A round led by Accel in 2024 and a $50 million Series B round in September 2025 co-led by Insight Partners and Khosla Ventures, with participation from Accel, Point Nine, First Round Capital and Prosus —bringing total funding to over $75 million to accelerate its vision for AI-powered Supplier Relationship Management (AI-SRM) and expand hiring across the US and UK. Backed by world-class investors and trusted by leaders across tech and enterprise, Omnea is positioned as a fast-growing innovator in the procurement and supplier management space, transforming an often-fragmented business function into a strategic advantage.
