Bonjour, je comprends que What’If doit aider les agences à simuler l’impact financier réel de leurs décisions médias. Comme les décisions doivent être prises vite, le dashboard et les simulations doivent rester simples et instantanées. Je construirais d’abord le cœur What’If avec sliders, calculs KPI synchronisés et sauvegarde de scénarios par client. Ensuite, l’IA propose des scénarios conservateur, optimal et agressif, avec explications lisibles sans jargon marketing. J’ai déjà livré des SaaS analytics pour agences ads où la fiabilité des projections conditionnait l’adoption produit. Avec ce périmètre, un MVP testable pour une agence pilote est réaliste en semaines. Souhaitez-vous valider d’abord la logique de simulation avant d’automatiser les imports publicitaires ?

Hello, I understand you need a SaaS platform, “What’If?”, for marketing and growth agencies to simulate changes in campaigns in real-time and make smarter decisions. The MVP will focus on a clear dashboard where users can adjust campaign settings with interactive sliders, instantly see KPI updates, compare scenarios, receive simple AI explanations, export results, and get basic alerts—all in a mobile-friendly, easy-to-use interface. I have 6+ years of experience building SaaS tools with responsive dashboards, interactive analytics, AI-powered insights, and secure multi-user access. I’ve integrated Stripe for subscriptions, created intuitive flows for users, and ensured clean design that works across devices while keeping things simple for non-technical teams. For your project, I can deliver a fully functional MVP including the dashboard, scenario simulations, AI-generated explanations, Stripe payments, and export/alert features. The code will be documented, deployable, and easy for your team to manage. I also provide three months of post-delivery support to ensure everything runs smoothly and would be happy to share examples of similar SaaS projects in a private chat. Best regards, Prasham Jain
