A single payment, no subscription and no card kept on file. You meet your named senior engineer and project lead, and before the week starts you agree one outcome: the work itself if you already know what you want built, or a scored shortlist of the AI opportunities in your business and a recommendation of what to build first if you do not. You finish the week with the completed work and a written recommendation of the next step, and both are yours whether or not you continue. - After payment, a booking calendar opens for scheduling the kickoff with the named senior engineer and project lead; the Loop team emails within one business day for anyone who does not book. The outcome for the week is agreed at that kickoff, before work starts. - Nothing is charged on day 8. If you continue, the subscription is started by a Stripe link and month one is the full 6,400 euros; the 500 euros is not credited against it. ## Plans - Start, 6,400 euros per month: one active project, named senior engineer and project lead, managed hosting, monthly operations report. - Embedded, 12,800 euros per month: two active projects in parallel, senior engineer and project lead, design and data expertise as needed, quarterly AI roadmap. - Team, from 25,600 euros per month: dedicated senior team across the client's AI roadmap, weekly working session, board-ready reporting. All plans: full code and IP ownership by the client, managed hosting, monthly reporting. Cloud infrastructure, model usage and third-party licences billed separately. ## Process 1. AI Readiness Audit, up to two weeks, run whenever the first priority is not yet clear: processes, data and integrations mapped; candidates scored on expected return on investment, technical feasibility and data readiness. Clients who already know what they want built skip straight to the build. 2. Build: first system typically live two to four weeks after kickoff. 3. Operate: hosting, monitoring and a monthly operations report. ## Contact - https://loop.twistag.com/#audit
