Fitness is habitual — once someone starts using a tool, retention is incredibly high
Wearable data (Apple Watch, Oura, Whoop) creates opportunities for AI-powered insights
The creator fitness economy is booming — trainers need tools to monetize online audiences

Having an idea is step one. Validating it before investing time and money is what separates successful founders from the rest. Here's how Foundry helps:
Answer 5 quick questions about your interests and skills. Our AI analyzes the fitness market to find niches with high demand and low competition.
Two AI agents debate your idea: the Seeker finds opportunities, the Destroyer finds flaws. You get an honest, data-backed assessment that friends and family can't provide.
Once validated, Foundry generates a complete business plan with financial projections, plus your brand identity (name, colors, fonts, domain availability).
General fitness apps are crowded. But niche fitness (prenatal fitness, over-50 strength training, wheelchair fitness, sport-specific training) has massive gaps. Go narrow, go deep.
Subscription models ($10-30/mo for consumers, $50-200/mo for trainers). Other models include equipment sales, affiliate commissions on supplements, and B2B workplace wellness programs.
Not for the tech side. Partner with certified trainers for content. Focus on the platform, AI, or tools that make fitness professionals more effective.
