Idea type: Minimal Signal

There’s barely any market activity - either because the problem is very niche or not important enough. You’ll need to prove real demand exists before investing significant time.

Should You Build It?

Not yet, validate more.

Your are here

Your idea for a TypeScript training course that leverages free resources and focuses on exercise-based learning falls into a category with minimal market signal. The fact that only 2 similar products were found suggests that this is either a very niche problem, or one not considered important enough by many people. With only 2 similar products found, confidence in this assessment is low, and engagement is also low, with the similar products averaging only 2 comments each. This means you'll need to do some serious validation before sinking significant time and resources into building this. The good news is there is not much competition yet. Your approach of using free resources in a structured manner could be a differentiator, but you need to confirm demand.

Recommendations

  1. Given the minimal signal, your immediate focus should be on validating demand. Start by actively participating in online communities where TypeScript developers hang out (e.g., Stack Overflow, Reddit, Discord servers). Introduce your concept – a structured, exercise-based TypeScript course using free resources – and gauge their interest. Ask specific questions about their learning challenges and if they'd find such a resource helpful.
  2. Offer to manually curate a mini-version of your course for 2-3 potential customers. This could involve creating a personalized learning path with exercises and providing direct feedback. This will give you invaluable insights into the content and delivery methods that resonate best with your target audience, while also allowing you to collect testimonials.
  3. Create a short, compelling explainer video showcasing the unique value proposition of your course: structured learning, exercise-focused approach, and use of free resources. Highlight the pain points it solves and the benefits learners can expect. Monitor how many people watch the video fully, as this will be a direct indicator of interest.
  4. To further gauge commitment, consider creating a simple landing page with a compelling description of your course and ask for a small, non-refundable deposit to join a waiting list. This will help you separate genuinely interested individuals from those who are just curious.
  5. Based on the feedback from similar products, focus on clarity and practical application. Highlight how your course helps build real-world tools and solve concrete problems. Differentiate yourself from platforms like Codecademy by emphasizing the depth and structure of your curriculum.
  6. If you are unable to find at least 5 truly interested people in 3 weeks, you need to rethink your approach or potentially reconsider the idea. Don't become emotionally attached to your initial concept; be prepared to pivot based on market feedback.

Questions

  1. Given the availability of numerous free TypeScript resources, what specific pain points or learning gaps does your curated, exercise-based course address that existing solutions don't?
  2. How will you ensure that the exercises are not only practical and relevant but also effectively validate learning and progress, providing a tangible sense of accomplishment for users?
  3. Considering the low engagement observed in similar product launches, what innovative strategies will you employ to foster a strong community around your course and encourage active participation and knowledge sharing among learners?

  • Confidence: Low
    • Number of similar products: 2
  • Engagement: Low
    • Average number of comments: 2
  • Net use signal: 22.5%
    • Positive use signal: 22.5%
    • Negative use signal: 0.0%

    • Positive buy signal: 0.0%
    • Negative buy signal: 0.0%

This chart summarizes all the similar products we found for your idea in a single plot.

The x-axis represents the overall feedback each product received. This is calculated from the net use and buy signals that were expressed in the comments. The maximum is +1, which means all comments (across all similar products) were positive, expressed a willingness to use & buy said product. The minimum is -1 and it means the exact opposite.

The y-axis captures the strength of the signal, i.e. how many people commented and how does this rank against other products in this category. The maximum is +1, which means these products were the most liked, upvoted and talked about launches recently. The minimum is 0, meaning zero engagement or feedback was received.

The sizes of the product dots are determined by the relevance to your idea, where 10 is the maximum.

Your idea is the big blueish dot, which should lie somewhere in the polygon defined by these products. It can be off-center because we use custom weighting to summarize these metrics.
