Pain Point #1: "Is stripe still the go-to for people running these kinds of platforms?"

Opportunity: Develop a payment processing solution tailored specifically for niche online marketplaces that prioritizes minimizing transaction fees without sacrificing service quality. This could involve innovative fee structures or leveraging blockchain technology.

Justification:
- Demand: Users express concerns over high transaction fees eating into their profits, particularly when combined with marketplace fees.
- ROI: By reducing transaction fees, sellers can retain more of each sale, potentially increasing revenue by 3-5% or more on average sales.
- Scalable: With the proliferation of niche online marketplaces, the need for such payment solutions is widespread, and a tech-driven solution could be easily replicated and adapted to different niches.
- Purple Cow/Controversial: Using blockchain or innovative financial technology to undercut traditional payment platforms while maintaining security could be disruptive and attract attention.

Pain Point #2: "I have this constant fear of “missing out” on great insights, so I reflexively save articles, tweets, videos… and now I’m overwhelmed."

Opportunity: Create an AI-driven platform that automatically organizes, prioritizes, and schedules content consumption tailored to users' interests and available time, minimizing digital overload.

Justification:
- Demand: Many users struggle with digital information overload and seek effective ways to manage saved content without feeling overwhelmed.
- ROI: Users save countless hours by having a system that highlights key pieces of content and schedules consumption, optimizing learning and productivity.
- Scalable: The tool can be scaled globally across multiple languages and integrated with popular content platforms like Twitter, YouTube, and news blogs.
- Purple Cow/Controversial: The concept of an AI personal assistant that curates content based on personal impact scores and learning schedules is futuristic and might surprise users with its accuracy and personalization.

Pain Point #3: "We’ve learned our device fits far beyond vending: It could sit at a school entrance and block unauthorized entry."

Opportunity: Expand the use of age verification technology into broader security solutions, such as school access control, which could use advanced facial recognition for personalized access and monitoring.

Justification:
- Demand: With growing concerns over school safety and security, there is a substantial market need for efficient and effective entry systems.
- ROI: Institutions could see a reduction in unauthorized access incidents, leading to increased safety and reduced liability, thereby justifying the cost in saved potential risks.
- Scalable: This solution can be implemented in various institutions beyond schools, such as government buildings, private offices, and residential complexes, indicating a large potential market.
- Purple Cow/Controversial: The dual use of age verification and security in a unified system leverages the strengths of identity tech in a novel security application, likely sparking attention for its ingenuity and practicality in modern safety solutions.
