TL;DR
Co-founders and brothers Jack and Nick Sweeney scaled Coherence—a nervous system regulation and breathwork mobile app—to $85,000 in revenue in just eight months. By prioritizing content creation before writing a single line of code, they used X (Twitter) as an idea battleground to validate concepts, which were then reverse-engineered into high-converting TikToks, Instagram Reels, and ultimately the app’s core features.
The Founder’s Story
Jack Sweeney is a non-technical founder with a background in digital content and no-code web development (though his early projects flopped). His brother, Nick Sweeney, is a former Division 1 cross-country skier who suffered a severe injury. After doctors predicted Nick would never walk normally again, he turned to breathwork out of desperation. Within three months, he was walking, and in six months, he was training full-time.
Nick began coaching others to manage chronic pain using breathing techniques. Seeking to scale this “medicine of breath,” the brothers teamed up to build a digital platform.
The Building Process
Jack and Nick built Coherence using AI coding assistants without writing manual code. The application is a highly aesthetic, gamified breathwork tool that features:
- Inhale and exhale sound-guided timers
- Streak tracking and gamification mechanics
- Six primary breathing categories (e.g. Coherence Breathing, Vortex Energy, Focus, Stress Relief, Sleep)
They launched the MVP in February 2025.
The Launch & Marketing Strategy
The brothers succeeded because they executed a strict content-first validation playbook, completely avoiding premature software development:
- X (Twitter) as an Idea Battleground: Jack wrote text threads on esoteric, spiritual, and breathwork topics. They monitored which ideas went organic-viral.
- Upstream Content Multiplier: When a text post gained traction, they translated it into short-form scripts for Instagram Reels and TikTok. If the short-form video exploded, they produced a comprehensive YouTube video.
- Polarizing Hooks: Their biggest viral hit (8 million views) featured a polarizing hook: “Do you want to know something that they don’t want you to know?”, playing into health awareness.
- ManyChat DM Automation: They integrated ManyChat with Instagram. When a reel went viral, viewers commented, triggering an automated DM containing the direct App Store download link.
- The Content-First Scaling Loop:
- Step 1: Pick a painful niche (breathwork/nervous system regulation).
- Step 2: Batch content ideas weekly.
- Step 3: Film bulk footage (30-60 videos at once, saving 2 months of content).
- Step 4: Put paid ad budget (“spark money”) behind the proven organic viral winners.
- Step 5: Outmarket everyone by posting relentlessly.

Key Tactics & Insights
- Reverse-Engineer Content into Code: Do not guess app features. Create content about the underlying problems first, analyze what goes viral (like their “Vortex Breath” video), and build those specific features into the app.
- ManyChat DM Conversions: High-volume short-form reach is useless without a frictionless download funnel. Use comment-to-DM triggers (ManyChat) to instantly deliver download links.
- Polarizing Hooks Drive Virality: Ambiguous, polarizing hooks (“what they don’t want you to know”) create massive curiosity gaps, boosting watch time and algorithmic push.
- The Sibling Leverage: Sibling co-founders offer high trust and emotional backup. When one is injured, sick, or burnt out, the other keeps the business running.
- Bootstrapped Spark Spend: Avoid spending broad ad budgets on untested creatives. Only put paid ad spend behind organic videos that have already crossed the viral threshold.
- Subscription Model Pricing: Coherence utilizes a 3-day free trial on its yearly plan ($40/year) and a standard monthly plan ($10/month).
