Startup cost: $500 - $3k

Setup costs range from $500 to $3,000 depending on the approach taken. At the minimum end, you would need to budget for essential tools like a computer, internet connection, and perhaps some basic software subscriptions for data analysis. On the higher end, investing in specialized software for AI development, marketing tools for outreach, and potentially some hardware for testing wearable integrations could increase the costs. Recurring fees may include software subscriptions and possibly advertising costs if you choose to run campaigns. While some may initially think this side hustle is low-cost, expenses can grow as you commit to more advanced tools and services. For someone looking to take this seriously, I would recommend budgeting around $1,500 to $2,000 to cover initial setup and running costs for at least the first few months.
