For my A3 venture pitch, I developed ManabuDen, a concept-stage Japanese-language learning platform designed to support both K–12 classrooms and independent learners.
The venture responds to a problem I see as a Japanese teacher learning about educational technology: interest in Japanese is high, but sustained progress can be difficult because of how challenging it is and how difficult it is to find quality content online. Teachers often rely on fragmented resources to build their lesson plans, while independent learners move between various apps, videos, grammar sites, and other materials without one coherent pathway. Japanese is a popular language, but I’ve noticed there’s also a lot of inaccurate generated content floating around as well—especially on social media. There’s a big need for accurate K-12 friendly content, and ManabuDen seeks to address that gap by providing a cohesive teacher validated pathway to learning Japanese—an idea I’m excited to share.
ManabuDen is designed around two connected experiences:
ManabuDen Classroom — a teacher-guided platform with lesson building, learning pathways, assignments, games, speaking practice, cultural learning, and progress tracking.
ManabuDen Learn — an independent learning environment built on the same Japanese-first content engine.
The venture begins with a school-first pilot strategy, using classroom implementation and educator feedback to validate the product before expanding to independent subscribers. For more information please take a look at the elevator pitch and venture pitch below.

Of course, ManabuDen is currently a concept-stage educational technology venture developed for this course (ETEC 522). Product features, financial projections, pricing, and pilot plans are all proposed here for academic purposes only.
I welcome feedback on the venture, particularly around the school-first business model, product differentiation, and potential for expansion from classroom use into the wider Japanese-learning market. If you’re a Japanese-learner, is ManabuDen something that you think you’d find useful?
Hi Kane, Great job on your VP and Elevator Pitch!
FEEDBACK:
I thought this was a really strong pitch because the problem, audience, and solution were all clearly connected. I especially liked the focus on providing a single, trustworthy learning pathway for Japanese learners instead of having students jump between multiple apps and websites. The classroom-first approach also felt realistic and gave me confidence that the venture is grounded in actual teaching practice.
I think where your pitch falls short is it is missing evidence of interest from teachers or schools, this would make it more clear as to how this educational technology product will be adopted . I also wondered whether the initial focus on Japanese language learning might limit growth although there is evidence to support the large scale of Japanese language learning. Would you expand the model into other languages or subject areas? Overall, I think this is a thoughtful idea with a clear niche and strong potential 🙂 Hope you bring it to life one day!
Overall, I thought this was a really well thought-out pitch. I liked that it focused specifically on Japanese rather than trying to compete as another general language-learning platform. The combination of a classroom version and an independent learner version also made sense to me, especially since they use the same core content. I also thought the product mock-ups were really helpful because I could actually picture how both a teacher and a student would use it. The pricing, revenue example, and 15-classroom pilot also made the business side feel quite realistic.
One thing I was still wondering about was how manageable it would be to create and maintain all of the Japanese-specific content. The pitch itself identifies the amount of content quality assurance needed as a weakness, and the platform includes quite a lot, including curriculum pathways, games, speaking, listening, cultural learning, and AI support. I think a little more detail about who would develop and review all of that content as the platform grows would have made the scalability side of the pitch even stronger.
REVIEW: Hi Kane, I really appreciated the strength of your competitive analysis and the school-first validation strategy, particularly the decision to establish ManabuDen classroom before expanding into the consumer market. From an EVA perspective, I’m curious about the long-term B2B/B2C strategy. Although Classroom and Learning share the same content engine, institutional sales and direct-to-consumer language learning involve very different acquisition, support, and retention models. How do you determine when ManabuDen has sufficient validation and capacity to expand into B2C without diluting its advantage in the K-12 Japanese-learning niche? I would also be interested to see the size of the addressable K-12 Japanese-language market influencing that decision.
REVIEW:
Hi Kane, this was a strong and impressively detailed pitch! What stood out most was your “missing middle” comparison. I have tried learning Japanese through several apps, so I could absolutely relate to your point that tools such as Duolingo and Quizlet lack Japanese-specific depth, while WaniKani, Bunpro, and Renshuu do not support classroom workflows. The Teacher Lesson Builder and shared content engine also make ManabuDen feel distinct and scalable. I appreciated the clear 15-classroom pilot and transparent breakdown of the $250,000 investment.
My main concern is whether developing teacher-reviewed lessons, games, speaking tools, and cultural content for both schools and independent learners may be too ambitious initially. Starting with the Grade 9–12 classroom product would allow you to test whether it reduces teacher planning time.
I would invest after the pilot demonstrates teacher adoption, sustained student engagement, and willingness to pay.
Thank you!
REVIEW
This is a really good pitch! The founder’s credibility stands out immediately; being a high school Japanese teacher and educational technologist gives real insight into the actual classroom pain points. I like the two product streams with Manabuden Classroom for schools and Manabuden Learn for independent learners. The funding ask of $250,000 for MVP development, 15 classroom pilots, and validation over 18 months feels appropriately scoped for a concept stage venture.
I might invest in this venture with some more information. I am curious about a few things. Japanese language learning is a relatively niche market compared to Spanish or Mandarin, so I wonder about the total addressable market and long-term scalability beyond Japan-focused learners. There are established competitors in this space like Duolingo, WaniKani, and textbook publishers with digital components, so I wonder what specific differentiation ManabuDen offers beyond the Japanese-first positioning.
REVIEW:
Hi Kane, I really appreciated your venture pitch on ManabuDen. You did a good job articulating the market gap and user pain points, and your experience as a high school Japanese teacher makes both the pitch and you as a founder especially credible.
As an EVA, I’d be inclined to invest, contingent on you addressing the following points:
First, I appreciated your thoughtful strategy around staging a classroom-first rollout, then later expansion into the consumer market. That said, I’d be curious to understand the data-driven threshold behind that expansion decision. What metrics would you track, and what threshold would trigger the move into the B2C segment to minimize execution risk? I’d also want to see a differentiated GTM strategy for these two segments (as others in the thread have noted), since institutional and consumer buyers behave very differently, including your freemium-to-paid conversion strategy, and what privacy controls would govern it if you plan on including digital ads given the user base includes K-12?
Second, I’d be curious to get more details about the pilot design itself. What’s the methodological approach for the 15 classrooms, and what specifically will you be measuring (i.e. teacher retention, learning outcomes, learner qualitative feedback, teacher workload reduction, as possible examples, or some combination)? And what’s your plan for securing these 15 pilot schools? Have you run any focus groups or outreach yet to gauge interest?
Lastly, I’d want to see bottom-up serviceable addressable and obtainable market data, including target geographies and associated expansion strategies, beyond the total addressable market figures shown, and would also need to understand the ownership percentage and financing structure that the $250K ask represents, along with your exit strategy, including relevant comparable transactions in the category to help model potential investor return.
All in all, great pitch!

Hi Kane,
As a former ESL teacher and Mandarin language learner, I enjoyed reading through your business venture idea. I can tell that your experience as a Japanese language teacher has given you a lot of insight into the gaps of available online lesson building tools. What stood out to me was how your platform is a one-stop shop for Japanese language teachers to build lessons and track their students’ progress. I like how your lesson builder included the option of choosing asynchronous and synchronous activities. The gamification elements are a nice touch, too. I would have liked to know more about the differentiated instruction part; is this built into the learning paths?
As you mentioned, it seems like a big project to juggle but you have come up with a really neat concept. I wonder if it could potentially grow over time to incorporate other languages. 🙂
Great work, Kane!

FEEDBACK
Hi Kane, love seeing your focus on Japanese learning again! Your elevator pitch was creative and engaging with its AI-likeness and Japanese-themed art, very stylistic. My only consideration from watching the elevator pitch is that it is very English. Maybe lean more into the Japanese language-learning aspect, since the platform demonstrations in the video only show what look like data graphs or analytics. I wonder if you could showcase other aspects of the platform learning, such as lessons, games, activities, or culture. The dashboard images included in the venture pitch would be a great addition to the elevator pitch videos.
With language learning as the focus of ManabuDen, would the learning focus more on speaking and listening, reading and writing, or all four? I think this would also show potential investors how ManabuDen differs from Duolingo or Quizlet, since ManabuDen is Japanese-focused and supports deeper, immersive learning, which is mentioned in your venture pitch, but could be a quick mention in the elevator pitch? Overall, there’s a lot of potential in this area!
REVIEW: ManabuDen is a highly practical idea for language teachers who spend hours piecing together fragmented Japanese resources. Your background as a Japanese and IT teacher gives this pitch a lot of credibility and a clear educational focus.
Looking at this through an EVA lens, the core concept makes a lot of sense. Bridging the gap between apps like Duolingo and deep study tools that ignore teacher workflows is a smart niche. That said, I feel that the marketability and venture plan might raise some red flags for me as it relates to a ROI. I wonder how big the K to 12 market for this would be compared to something like French or Spanish? I also wonder about the sheer amount of work required to build and maintain high quality games, speaking tools, and cultural content for both schools and consumers on a $250,000 budget. Competing with established giants in the consumer space might be difficult. There’s part of me that feels that one of the biggest risks here is that the scope might be too ambitious from the get-go.
Funding recommendation: Fund with qualifications. I would want to see a much narrower initial focus, perhaps just the high school classroom tool, along with pilot data showing it actually saves teachers planning time before expanding to independent learners or district wide.
FEEDBACK
Hi kanemerc,
Your pitch clearly identifies both sides of the problem. Learners need a trustworthy, structured pathway, while K-12 Japanese teachers need curriculum-aligned tools that reduce the time spent curating content.
My favourite part of the pitch is the “missing middle” position. ManabuDen is not trying to compete directly with broad consumer apps like Duolingo or highly specific tools like WaniKani or Bunpro. Instead, it targets the intersection of Japanese-specific depth, teacher workflows, and more. The product mockups were also strong and helped make the teacher lesson builder, student pathway, and independent learner dashboard feel concrete! Well done!
REVIEW
I was very impressed by the detail and specifications you provided about your product. I had never really thought about the lack of applicable applications for languages that have a much more complex system, at least apps that are effective. As an educator of that language, you have a vast toolbox of skills and experience to draw on to make this platform the best it can be.
From an EVA perspective, many above have already addressed these areas, but I digress. What would be the deciding factor for a single teacher vs. a district purchasing the offering for both models? Is the need for district licensure large enough? Will there be a proven profit from the use of free trials? We need to address these areas before considering investment. How can we see the pilot’s effectiveness? Is it effective for learning outcomes, and will it keep learners engaged in the app? The idea is cool, but before I fund it, it needs to show numbers, prove students actually learn better, and present a clear plan for how they’ll convince real schools to buy it.
FEEDBACK
Hi Kane,
Well-researched pitch. I liked the “missing middle” positioning against Duolingo, WaniKani, Bunpro, and Renshuu. It makes the gap in the market easy to understand, and the Japan Foundation and Duolingo data does a good job supporting the demand for Japanese learning. I’d be interested in hearing more about how the “teacher-reviewed AI support” feature would be managed, since content quality is already identified as a key risk.
I also liked the dual-engine model, with Classroom and Learn sharing the same content. It makes the later B2C expansion feel more practical since the same core content can support both sides without requiring the development work to be duplicated.
The elevator pitch was well done and you had my interest to move to the venture pitch.
I see potential as you clearly defined your niche, customers, and stakeholders. You also did a comparison to why others are different and where the gaps are. Your SWOT clarified additional areas.
I can see the value for the niche that you would create this for but do have to wonder if it may be vulnerable to existing players adopting your features and would need more clarity on how to prevent this. I am not a no but a need more information to say yes. I like the timeline. It seems realistic and well thought out. The budget seems low for one that includes a school rollout. The graphics and images are well chosen and visually appealing. One question…. I’m curious about the name and what it means.
