Fullstack Product Engineer at IconicShift, London, £Contract Rate
Contract Spy London, UK
About IconicShift IconicShift AI is building a platform that turns founder intent into usable strategic outputs — clear strategies, investor-grade pitches, and practical roadmaps. It is based on the experience of Mike Harris, founding CEO of First Direct (the world’s first telephone bank), founding CEO of Egg (the world’s first internet bank), and CEO of Mercury Communications (that created some of the UK’s first mobile and cable networks). Most founders don’t fail because they lack ideas or options. They fail because their thinking drifts and they can’t afford the experienced support they need. Their story changes, priorities multiply, and the business loses its single direction. Most AI approaches just help them fail faster by accelerating rushed decisions. IconicShift works by creating a single source of strategic truth, where every decision is tracked and held to account. It refuses to move forward without explicit acceptance of core strategic bets, ensuring...
