The 5 Most Profitable Niches Nobody's Talking About

About this video

RJ Martinez, who says he has eight years in print-on-demand, presents five low-competition niches for Merch by Amazon, Etsy and other platforms, showing for each why he thinks it works and an Ideogram prompt to generate artwork quickly. The niches are: ’never underestimate an old man with a tennis racket’ (which he suggests varying by sport and by old man/old woman, with pickleball as another angle); ‘I can’t, I have plans with Bigfoot,’ which sellers are already adapting to Easter, Christmas, Thanksgiving and Valentine’s Day; simple text-based ’no golf today,’ which he suggests swapping to other sports; a school bus driver Valentine’s design with owls, where he advises asking what bus drivers like or asking ChatGPT; and a cute Valentine’s penguin with hearts, drawing on what people love about penguins such as how they walk and jump into water. Throughout he validates ideas by checking last-30-day BSR, reviews/ratings and search result counts, warns that AI output needs spelling checks and editing, and promotes his Top Research Design Vault, which he claims gives 20 niche ideas a week with prompts and keywords and access to over 1,600 ideas for $10 a month, plus a separate vault of ready-to-use designs.

Key takeaways

• Validate each niche with last-30-day BSR, ratings and search result counts before uploading, rather than guessing.
• Take a proven phrase such as ’never underestimate an old man’ or ’no golf today’ and swap in different sports to create new angles.
• Adapt a proven concept such as ‘I can’t, I have plans with Bigfoot’ to different holidays instead of copying a design directly.
• Use Ideogram or ChatGPT image prompts to spin up artwork fast, but check spelling and edit the output before listing.
• For occupation and animal niches, build designs around what that audience actually likes — e.g. what bus drivers like, or how penguins walk and jump into water.
