What's the deal? Forget 48-hour hackathons. We're packing a punchy, after-work hackathon into 2.5 hours of pure flow. No preset theme, no slides, no presentations – just Cursor and whatever you can ship before the playlist ends. How it works: Grab a slice, snag a seat, fire up Cursor.Design Engineering NightsWednesday, 10 September @ 6:00 pm • Register to See Address, Central London We (Sam & Tikhon) spent time looking for people like us - people who fell in love at the intersection of two disciplines, design and engineering. We searched for meetups, events, Twitter but couldn't find anything for design engineers. So we are bringing the finest design engineering minds in Europe together. Design Engineering Nights are a home to: 1. Share your own journeys (we know there's no straight path to be a design engineer) 2. Shine the spotlight on what the best design engineers do 3. Get the lowdown on how to get the best out of your tools, workflows, etc.FuckUp Nights London #1 - September 2025Wednesday, 10 September @ 6:30 pm • Register to See Address, Central London FuckUp Nights London is finally back... And we're relaunching with a bang! and a few brilliant failures. Join us for a night of raw stories, questionable decisions, and glorious lessons learned the hard way. What to expect? Absolutely nothing. That way, we can actually surprise you. Hosted by Saul Truman, a third time founder who lost $2m in under a year building the next Reddit.Life of a Founder // Stephen Whitworth (CEO of incident.io 🔥)Wednesday, 10 September @ 6:30 pm • Register to See Address, Central London Hosted by HYPE: An interview series with London's most visionary founders and CEOs. Life of a Founder is a candid, behind-the-scenes interview series with the most influential founders and CEOs shaping tech in London. We plan to have max 50 attendees with a focus on a classroom like open Q&A format. Stephen Whitworth is the co-founder and CEO of incident.io, the modern incident management platform transforming how engineering teams respond to failure. Inclusion as a Product Strategy: Using Your Influence for Meaningful ImpactThursday, 11 September @ 6:00 pm • 120 Aldersgate St, Barbican Great product leaders don't just ship features. They change lives. They think about who is being left out, so they can serve them more fully and fairly. Inclusion isn't a nice-to-have. It's a competitive advantage and a product strategy that drives better outcomes for users, teams, and businesses alike. Join us to discover how to turn your product influence into a catalyst for inclusive innovation, and why this matters now more than ever. This isn't a sit-back-and-zone-out session. Expect an energising, interactive experience designed to sharpen your thinking and expand your impact as a product leader.Beyond Context Limits: Building Enterprise-Grade AISunday, 14 September @ 11:00 am • Register to See Address, Central London Cohere, Expedite, Oxbridge AI X and Earlybird are excited to bring together builders for a hackathon focused on building with Cohere's leading retrieval models. Recent research has shown that even though context windows are getting larger, performance degrades meaningfully as you scale context utilisation. The long-running debate between RAG vs growing context windows isn't going away, but this recent data suggests RAG is here to stay, especially in the enterprise. We'll be giving participants access to Cohere's Embed and Rerank models to build RAG applications.That's it for this week's Raise Your Profyle!
