What Is WARP, the Young Technical Entrepreneur Development Program?

WARP is a three-month program run by TIMEWELL that develops technical entrepreneurs — people who can build applications using AI, even with no prior development experience. TIMEWELL brings more than eight years of experience in new business incubation and startup support, and the program leverages the knowledge and networks of that team to the fullest extent to support each participant's growth.

Specifically, the program offers specialist tracks across three domains: business development, app development, and regional implementation. Business development covers the full arc from conceiving a business idea through business planning to prototype development — learned through hands-on practice. App development equips participants with practical skills using Cursor, building the ability to bring their own ideas to life. For regional implementation, TIMEWELL works with partner municipalities to give participants the opportunity to conduct proof-of-concept trials with actual deployed applications.

In recent years, the emergence of Cursor — a development tool powered by generative AI — has made it possible to build applications using natural language, and development speed has reached up to 50 times faster than conventional approaches. That said, appropriate development methodology — covering security and scalability — remains essential. Being able to use the tools is not enough on its own. WARP provides systematic instruction across all of these areas, delivering thorough support for building each participant's application development capabilities.

The four participants who presented at this session demonstrated exactly the skills developed through WARP, building impressive applications in just one week. The four applications introduced below are clear evidence of what WARP makes possible, offering a glimpse of the kind of innovation that generative AI enables.

"RESCAPE" — Science-Backed Healing Travel Experiences (Mana Wada)

What I built is "RESCAPE" — a service designed to deliver science-backed healing travel experiences that make you look forward to tomorrow. With a background in psychology, I had long noticed a problem: people dealing with mild depressive symptoms or mental fatigue — especially introverted people — tend not to make the most of their time off.

The solution I conceived was a system that assesses users' personality traits based on psychological frameworks like the Big Five and stress-coping theory, then recommends the optimal healing experience for them. The key feature is a three-minute assessment that generates a personalized experience plan.

For development time: the frontend took roughly two days, the login and authentication function took one day, and the assessment feature took about four days of error-fixing and iteration.

I put the most effort into the assessment feature. Everything — from designing the prompts sent to generative AI, to the database structure, to crafting the assessment questions — was determined using the AI capabilities inside Cursor. This produced a solid foundation capable of deeply understanding users' personality traits and proposing experiences tailored to them. I also worked to integrate APIs, making it possible to connect with existing psychological assessment tools.

Currently, the system implements the full flow from assessment to suggesting a healing experience. Going forward, I'd like to add an actual purchase function to develop it into a more complete, practical service.

"UPLOGUE" — AI-Powered Travel Diary and Guidebook App (Yu Takano)

What I built is "UPLOGUE" — an application that auto-generates travel records using AI and serves as a guidebook. In my day job working on new business development, I kept running into two problems: many people find keeping travel records tedious, and there's a real shortage of information about niche travel destinations.

The goal I set was a service where travelers upload just a few photos and a travel record is generated automatically. The system infers the travel itinerary from location data and timestamps embedded in photos, then weaves in information about places visited to produce a narrative record. This lets users preserve their travel memories effortlessly, without any manual effort.

Additionally, the records users post serve as a useful guidebook for other travelers — records are displayed on a map organized by destination, making real-world information accessible. I'm also exploring the idea of offering token rewards for records about lesser-known regions, with the hope of accumulating more diverse geographic coverage.

Using the skills I developed through WARP, I went on to build not only this application, but three others as well — an app that proposes solutions to organizational challenges, and an app that suggests regional migration destinations — four applications in total, built in a short time. Putting tools like Cursor to work has convinced me that an era has arrived where anyone with an idea can build an app.

This experience of building apps deepened my own sense of generative AI's potential. Cursor's natural language processing and database integration capabilities are particularly powerful — they dramatically reduce development effort. At the same time, I realized that being able to articulate what you want clearly, in language that works effectively in dialogue with AI, is a critical skill. The mentors in WARP were also invaluable — having someone available to work through problems with made development go much more smoothly.

A Booking Management System for Esthetic Salons (Yuna Takahashi)

What I built is a booking management system for esthetic salons. I've been helping out at a small, locally focused salon where I'm working toward an esthetic qualification, and I've seen firsthand how the salon struggles with expensive digital systems being out of reach — leaving them to manage bookings manually with a limited staff.

My goal was to build a booking management system with a low implementation cost, designed so salon staff could focus on conversations with clients and on treatments. I kept the scope focused on user registration and the booking function, prioritizing simplicity of operation. I implemented authentication and database integration using Supabase, which I learned through the program.

The biggest challenge in development was getting the hang of Cursor. It was my first time using it, and I couldn't quite get the hang of certain features — I ran into frequent errors around authentication in particular. At one point I considered scrapping the entire project and starting over, but I built out a thorough requirements specification document and managed to rebuild the system from scratch in just two days. That experience taught me that the key to using AI tools like Cursor is being able to clearly articulate what you're trying to do in words, and then getting more specific through dialogue with the AI.

The core booking management features are now fully implemented. Going forward, I'd like to have actual salon staff use the system and use their feedback to expand its functionality. Longer term, I'm thinking about adding customer management features and treatment record management, building it out into a comprehensive system that supports running a salon.

"Hatsutabe" — A Personalized Baby Food Guide (Shunzo Okada)

What I built is "Hatsutabe" — a personalized guide system for introducing solid foods to infants. As a parent going through this experience myself, I was overwhelmed by the sheer volume of information about baby food and couldn't find a clear path. That experience led me to recognize the need for a system that provides information personalized to a child's age and developmental stage.

The system asks users to input information at registration: the child's birthday, sex, when solid foods were started, allergies, and so on. Based on that information, it recommends recipes and an approach to introducing solid foods that's optimal for that child. I'm aiming to build a mechanism that accumulates users' parenting records and provides increasingly personalized suggestions as the child grows.

For someone like me with no programming experience, app development was completely uncharted territory — but by using Supabase, which I learned through WARP, I was able to implement core features including login functionality and personalized content display based on the child's profile. Supabase's database features were particularly intuitive, and I was able to get data management and retrieval working within a short timeframe.

Looking ahead, I want to use the large volume of baby food data accumulated from users to build a service that transforms how solid food introduction is approached — including things like predicting food allergy risk. I'd like to connect with medical institutions and research organizations and give data-driven insights back to society.

Summary

Each of the four participants at today's session used the AI-powered development skills they developed in WARP to build impressive applications in a short time.

Taking a problem they'd identified from their own experience, engaging seriously with it through the power of AI, and turning a solution into reality — through that process, I believe they each deepened their understanding of what matters in development: the importance of requirements definition, how to use Cursor effectively, and more. The experience of building these apps also likely renewed their sense of what generative AI makes possible — and of how critical the ability to articulate your intentions clearly is to using it well.

These results suggest that an era has arrived where people who aren't engineers — if they have an idea and the drive — can build applications themselves using AI. Generative AI is, of course, only a tool, and making the most of it still requires human creativity and problem-solving ability. But the arrival of tools like these has broadened the pool of people who can be drivers of innovation.

WARP is precisely the kind of course for non-engineers that stands at the leading edge of this shift — a program that supports business development, app development, and regional implementation as a total package, with a mission of producing people who can drive innovation. For participants, the goal isn't only technical skills — it's also the ability to identify and frame problems, solve them, and collaborate effectively with AI.

Today's presentations were the showcase for WARP's first cohort. Applications for the second cohort have already opened (as of February 2026). Whether or not you have programming experience, if you have the drive to take on social challenges, we warmly welcome your participation.

The future belongs to those who take the skills they develop in WARP and use them to create new forms of innovation in their areas of interest. We're excited to see more and more challengers shaping that future. The day when new services and solutions powered by generative AI appear across every sector of society may not be far off. WARP is committed to riding that wave of change alongside all of you — and we're here to support everyone who takes on the challenge, every step of the way.
