You Have the Idea — But You Lack the Technical Ability to Turn It Into a Product
You have the idea — but you lack the technical ability to turn it into a product. In this lecture delivered by Yoshiki Ando, remarkable examples are introduced: students with virtually zero programming experience built web applications in just a few weeks and carried out actual customer validation. By leveraging AI-driven development tools "V0" and "Cursor," the technical hurdle is dramatically lowered and the methods for rapidly turning business ideas into reality are explained concretely. Development that traditionally took months can now be deployed in just two clicks. What entrepreneurs need is not technical ability — it is the execution to listen to customers and continuously iterate improvements.

Achieving Ultra-Fast Deployment With V0
Today I will explain practical methods for AI-driven development and the flow from actual web application development through to deployment. I will cover the V0 and Cursor development methodology specifically, with actual steps woven in.
First, V0. V0 is genuinely simple — you can publish an application to the world in just two clicks. The actual steps are: once development is complete, press the Share button in the upper right and select "Deploy." That alone generates a URL and the application is published. Share it with someone and they can access it immediately. When you want to get a first impression from a customer, or check what kind of reaction you will get — V0's deployment feature is extremely convenient.
However, there is an important note: V0 has restrictions on external service integration. When building an application that integrates with external services, you cannot preview it, so you end up publishing without being able to verify whether it actually works. Therefore, V0 is good for testing the appearance only — it is not suitable for implementing complex features.
V0 also has the problem that when an issue occurs with the application, fixing it is difficult. Cursor allows detailed version management, but in V0 you can fix things by version, but fixing only specific parts is difficult. From a quality assurance perspective as well, using Cursor is recommended for serious development.
Serious Development and Deployment Using Cursor
Next, let me explain the flow from development in Cursor through to deployment. First, as an important preparatory step, there is the work of forking a GitHub repository to your own account.
The specific steps are: open the repository on GitHub and press the "Fork" button on the right. Your account name will appear — press "Create Fork." This copies the original code to your own repository.
Next, you need to change Cursor's connection destination. Open the Terminal and enter the git remote set-url origin command followed by the URL of the new repository. The URL can be copied from the green "Code" button on GitHub. Remember to include a half-width space after "origin." This ensures that what you develop is contained in your own account.
Deployment Uses Vercel
Deployment uses Vercel. Vercel is a hosting service by the company that created V0, and it can easily publish web applications in conjunction with GitHub. If you have a V0 account, a Vercel account has also been automatically created.
The Vercel deployment steps are: select "Project" from "Add New," choose the repository you want to import, and press the import button. After entering the project name, the critical step is setting environment variables. Select and copy all the information written in the .env file and paste it into the Environment Variables field. Pasting all at once automatically sets all environment variables.
Once environment variable setup is complete, just press the "Deploy" button. If there are no issues with the application, publication is complete. On success, a "Congratulations" message appears, and you can confirm the published URL from "Continue to Dashboard."
However, It Often Does Not Go Right on the First Try
However, it often does not go right on the first try. If an error appears, copy the error content, paste it into Cursor, and have the AI fix it. After fixing, do not forget to push to GitHub. Since GitHub and Vercel are linked, pushing changes to GitHub will automatically reflect them in Vercel.
Furthermore, in actual production environments, branch-based development becomes important. Place the code used as the product in the main branch, create new features in a development branch, and then merge into the production environment after verification is complete. This minimizes the risk of issues occurring in the environment customers are using.
On environment separation: the common flow is to develop in the local environment, verify in a test environment, and finally deploy to the production environment. These environments are switched via environment variables. For example, setting different values for each environment — my Neon and Clerk connection information versus someone else's — separates the test and production environments.
Finally, Many Wonderful Products Were Presented at Today's Showcase
Finally, many wonderful products were presented at today's showcase. What was particularly impressive was that people with almost no engineering experience were able to build actually functioning applications in this short period and even carry out customer validation. This demonstrates the power of AI-driven development. Further evolution — such as new versions of ChatGPT — is expected going forward. When 20,000,000 tokens of processing power becomes standard, development at previously unimaginable scales will become possible. The technical barrier is definitely falling. What matters is the execution to listen to customers and continuously iterate improvements. Please leverage what you learned in this lecture and connect it to actual business.
The most important point from this lecture is the fact that AI-driven development has dramatically lowered the barrier to entrepreneurship. The example of students with almost no programming experience developing functioning web applications in just three weeks and receiving POC (Proof of Concept) requests from multiple companies tells this story clearly.
Tools like V0 and Cursor compress development processes that traditionally took months into days — or in some cases hours. However, the purpose is not to learn how to use tools. What matters is how quickly you can listen to customer feedback and iterate improvements using these tools.
Do Not Be Constrained by Technical Limitations — First Turn the Idea Into Something Tangible
Do not be constrained by technical limitations — first turn the idea into something tangible. Then have actual users touch it and gather feedback. The ability to cycle through this loop at high speed has become the most important capability in modern entrepreneurship.
Going forward, AI evolution will accelerate further. In an era where 20,000,000 tokens of processing power is standard, what is required of entrepreneurs is not technical ability — but creativity and execution that deeply understands customer challenges and produces valuable solutions.
The methodology learned in this lecture is merely the starting line. What matters is to actually move your hands, not fear failure, and continue learning persistently. Now that the democratization of technology is advancing, this is the best possible chance to put your ideas to the world.
