๐ Need to turn an idea into a properly architected AI MVP without overbuilding? Iโm an AI MVP architect, 20+ year multi-time founder and AI full stack developer. I help founders take a clear idea and turn it into a real, usable MVP quickly, without months of planning or guesswork. I have had products feature on Dragons Den, Techstars, raise $5m+ in VC and scaled businesses to 8 figures. I bring all of that experience to all of my engagements and can essentially be your technical cofounder. Iโve built and launched enough products to know that most MVPs fail because the wrong things get built first. Too many features, too much complexity, or AI added without a clear purpose. My job is to help you decide what actually matters, design it properly, and then build it end to end. I typically work with early stage founders and small teams who want momentum but still care about doing things right. Once scope is clear, I can deliver a fixed scope full stack MVP in as little as seven days, including frontend, backend, AI logic, and deployment. I also regularly remain with my clients in a fractional CTO role - to help continue the product roadmap and momentum. Iโm a UK based founder and lifelong product builder. My startups and software have been featured on Dragonsโ Den, Techstars, and London Tech Week. I have been on both sides of the table, building, pitching, iterating, and killing ideas that did not deserve more time or money. If you already have the idea and want a senior builder who can think and execute, send a short message describing what you are building and where AI fits. I will tell you quickly if it is a good fit.
