What you'll find on GradeBuilder

Practical mini-courses and articles that help launch startups in different countries of the world

We don’t waste time on abstract theory. Each course is short, practical, and focused on action: how to validate your startup idea, how to find your first customers, how to register a company, and where to look for startup funding. You’ll learn step by step how to launch an MVP, build traction, and prepare your business for investors or accelerators.

Can I start a startup while working full-time?

Yes. Many founders start their projects part-time while keeping a job to cover expenses. The important thing is to use your limited time efficiently: focus on customer discovery, build the smallest possible version of your product, and test the market. We share frameworks that help you balance work and startup life, and move toward full-time entrepreneurship when you’re ready.

What can I learn here if I want to start my own startup?

We focus only on what really helps founders launch. All courses are short, practical, and action-oriented: how to validate your startup idea, how to do customer discovery, how to build an MVP, how to register a company, and how to raise seed funding. You’ll learn startup basics like unit economics, business models, and pitch decks, plus advanced topics such as scaling to international markets, preparing for accelerators, and building a cap table. Our programs are built for first-time founders who are searching for answers to common questions like how do I test if my idea will work, where can I find my first customers, how can I get investment, and how do I launch a startup with little money.

How much money do I need to launch my startup?

You don’t need millions to begin. Many startups start with little or no funding by using free tools, low-code/no-code platforms, and customer interviews instead of expensive research. The key is to test your assumptions early, validate your market, and then decide if outside investment is needed. Our programs explain how to build a startup with minimum budget and prepare for fundraising when the time is right.

I only have an idea — is this for me?

Yes. Even if you’re just at the idea stage, our startup courses will help you test your assumptions, validate your market, and find your first customers. You’ll learn step by step how to turn an idea into a simple MVP and start collecting feedback before spending money on full development.

Do I need a team to start a startup?

Not always. Many successful founders begin solo, test their startup idea, and only later bring on co-founders or first employees. At the beginning, what matters is validating your idea, building a simple MVP, and finding your first customers. Our courses show you step by step how to start a startup, even if you don’t yet have a team or investors.

How do I know if my startup idea is good?

A good idea is not about how “brilliant” it sounds, but about whether people actually need it. The fastest way to know is by validating your startup idea: talking to potential customers, testing simple prototypes, and measuring real interest. Our lessons show you practical tools to check if your idea has potential before investing time and money.
