Their strategy deviates significantly from traditional app building by prioritizing content validation through social media before developing the actual product, a method they attribute to their success, especially given Nick's background as a former D1 cross-country skier who recovered from a career-ending injury through breathwork. ## Detailed Analysis Jack and Nick Sweeney, co-founders of the Coherence app, detail how they achieved $85,000 in revenue and 15,000 downloads in just eight months by employing a 'content first' strategy rather than building the app before validating the idea. Nick Sweeney, who turned to breathwork after a debilitating injury ended his skiing career, started by creating content on spiritual and esoteric topics related to breathwork on platforms like X and TikTok. A key viral moment was a tweet explaining the 'Vortex Breath' cadence, which accumulated 535K views, proving market demand. They followed a five-step playbook: 1. Pick a painful niche, 2. Batch ideas weekly, 3. Film in bulk, 4. Amplify winners, and 5. Outmarket everyone. Crucially, neither brother wrote any code for the app, instead using AI coding agents like Claude and OpenAI Codex to build the functional app, which costs approximately $5,800 monthly to run (including costs for video editors, influencers, ghostwriters, and VAs). The app offers guided breathing techniques for relaxation, focus, energy, and sleep. ### Coherence Metrics & Background - Coherence achieved $85k revenue and 15k downloads in 8 months - Nick Sweeney, a former D1 skier, healed from an injury using breathwork, inspiring the app's creation - The app helps users regulate their nervous system through breathwork exercises. ### The Content-First Strategy - They started creating content about spiritual/esoteric breathwork topics on X and TikTok before building the app - A tweet about the 'Vortex Breath' went viral (535K views), validating the idea before any coding occurred. ### Building & Launching Playbook - The 5 steps are: 1. Pick a painful niche - 2. Batch ideas weekly - 3. Film in bulk - 4. Amplify your winners - 5. Outmarket everyone - They explicitly avoided writing code, using AI tools for development. ### Tech Stack & Costs - Stack includes Expo ($19/mo) for the framework, Supabase ($25/mo) for backend, Claude ($17/mo) and Codex (Free) for AI coding agents, Mixpanel (pay-as-you-go) for analytics, RevenueCat (pay-as-you-go) for payments, Vercel/Next.js (Free) for hosting, Figma (Free) for design, Rotato ($89/yr) for 3D design, and ManyChat ($15/mo) for DM automation - Total monthly operating costs are approximately $5,800, with revenue around $12,000 resulting in a 48% profit margin. ![Screenshot at 0:00: Jack and Nick Sweeney introduce themselves as the co-founders of Coherence, noting 15k downloads and $85k revenue.](https://ss.rapidrecap.app/screens/nsn94Ad47GY/00-00-00.png) ![Screenshot at 0:23: A slide displays Nick Sweeney's tweet stating, 'Content before product is the future,' outlining the core strategy.](https://ss.rapidrecap.app/screens/nsn94Ad47GY/00-00-23.png) ![Screenshot at 1:33: Nick Sweeney details Coherence's initial metrics: $11,000 MRR, $22,000 highest month, 2,000 users, and 15,000 downloads.](https://ss.rapidrecap.app/screens/nsn94Ad47GY/00-01-33.png) ![Screenshot at 10:30: A slide detailing the tech stack, listing Expo \($19/mo\) as the framework, Supabase \($25/mo\) for backend, and Claude/Codex for coding agents.](https://ss.rapidrecap.app/screens/nsn94Ad47GY/00-10-30.png) ![Screenshot at 11:03: A breakdown of monthly operating costs shows $2,500 for video editors, $1,000-$2,000 for influencers, and other expenses totaling approximately $5,800.](https://ss.rapidrecap.app/screens/nsn94Ad47GY/00-11-03.png)
