Welcome back to Startup Sphere - the startup ideas newsletter for builders, entrepreneurs, and operators.

Over the past weeks, I’ve been working on the new Startup Sphere Insights product. The goal is to build a tool that will give users the confidence to build out their idea, instead of chasing after the wrong ones.

I recently shipped a trends report, which shows trends and search volume for keywords related to an idea. This is another step forward in helping you build with confidence.

If you’re still looking for the right idea to build, sign up for Startup Sphere Insights and let me know how you like it!

Now on to this week’s big idea.

TODAY'S BIG IDEA

🛑 The Problem: Performance-focused athletes and biohackers spend hours piecing together supplement advice from Reddit threads, podcasts, and influencer content, then end up buying from a handful of different vendors with no consistency in quality and no real guidance suited to them.

💡 The Idea: Build a direct-to-consumer supplement brand that bundles curated recovery and biohacking formulas with protocol recommendations tailored to the athlete's sport, training intensity, and goals. It would sell through both subscriptions and one-time purchases, pitching its formulations as essential gear for serious athletes rather than just another vitamin.

⚙️ How it Works: Customers fill out a short questionnaire covering their sport, training frequency, recovery bottlenecks, and budget, then get a customized supplement stack recommendation. Email and SMS can handle the education on protocol timing and stacking, which brings customers back and pushes up average order value through upsells.

📖 The Playbook: Find 5 active fitness and biohacking communities on Reddit (r/fitness, r/Nootropics, r/AdvancedFitness, r/Supplements, r/Biohacking) and spend 2 weeks there giving real protocol advice and answering supplement questions without mentioning your brand.

The full playbook strategy is available on Startup Sphere Insights.

💵 The Numbers: TTM Revenue: $2.6M | TTM Profit: $343k | Asking Price: $749k

📈 The Trend: nootropics supplements (22200/mo, rising, +107%)

The search for nootropic supplements is on the rise, making this a perfect opportunity to build a personalized product line for athletes.
