How to create a start-up: the key steps to launch your project

Creating a start-up is an exciting and challenging journey for entrepreneurs. It’s an opportunity to turn an innovative idea into reality, take on new challenges and sometimes even revolutionize an entire industry. However, the process of creating a start-up can seem daunting and complex for those embarking on this adventure for the first time. From the first idea to implementation, what are the key steps to take to turn your project into reality ?

What is a startup?

A start-up is often associated with a young technology company. However, not every new business is a start-up, and not every start-up necessarily develops an app or a digital innovation. Start-ups are generally defined by their ambition to develop an innovative business model with the potential to grow rapidly.

But there is a catch: start-ups often operate in highly uncertain environments. They need to test their idea, find their market, win their first customers and sometimes raise funds to accelerate their development. Their goal is to gradually turn an innovation, or a new way of meeting a need, into a viable and repeatable business model. And that always involves an element of risk.

Start-up vs traditional company

A traditional business is generally built around an already proven business model. A restaurant, consulting firm or local retailer knows how it will deliver its products or services, find customers and generate revenue. Growth is often gradual and requires additional resources, such as new employees, larger premises or additional equipment.

A start-up ventures further into the unknown. It often seeks to solve a problem in a new way and still needs to prove that its model can work at scale. It therefore develops step by step: creating a prototype, testing it with users, refining the offer and, once the model has been validated, accelerating growth.

What makes a project innovative and scalable

Innovation is one of the defining characteristics of a start-up. It may be technological, but it does not have to be. A company can also innovate through its service, distribution model, customer experience or business model.

Another essential concept is scalability. A scalable business model can significantly increase revenue without its costs rising at the same rate. A digital platform, for example, may be able to serve thousands of additional users without having to increase its workforce proportionally.

Innovation and scalability largely explain both the potential and the risks associated with start-ups. Before trying to grow quickly, founders first need to make sure that a genuine market exists. A good idea only becomes truly interesting when it finds customers who are ready to embrace it… and pay for it.

The key steps to create your startup

Creating a start-up does not begin with designing a logo or registering a company. Before launching a business, founders need to make sure their idea is relevant, build a viable business model and bring together the right skills.

Find and validate your idea (market research)

A good start-up idea generally begins with a real problem for which there is genuine demand. The first step is therefore to identify your potential customers, understand their needs and analyse the solutions already offered by competitors.

Market research helps turn intuition into evidence. Interviews with potential customers, surveys, competitor analysis or testing an initial prototype can all help assess whether people are genuinely interested in the project. The objective is simple: make sure there is a market before investing heavily in the solution.

Build your business model canvas and business plan

Once the idea has been validated, the Business Model Canvas can be used to structure the business model: value proposition, customers, distribution channels, revenue streams, costs, resources and partners. It provides a concise overview of how the future company will operate and makes it easier to test different assumptions.

The business plan goes further by detailing the strategy, market, objectives and financial forecasts. It helps assess the viability of the project and becomes particularly important when seeking to convince a bank, business angels or other investors to finance its development.

Choose a legal structure and register the company

The choice of legal structure depends on several factors, including the number of founders, the desired governance model, financing requirements and plans for future growth. In France, start-ups incorporated as companies frequently choose the SAS (société par actions simplifiée) or SASU (société par actions simplifiée unipersonnelle), particularly because of their flexibility. However, the most appropriate structure will depend on the specific characteristics of each project.

The next step is to officially set up the company. This involves drafting the articles of association, establishing the share capital, publishing a notice of incorporation when required and submitting the registration application through France's one-stop shop for business formalities. Other issues, such as intellectual property and the allocation of equity between founders, should also be considered from the outset.

Build your founding team

It is possible to create a start-up alone, but surrounding yourself with co-founders who have complementary skills can be a real advantage. Someone with a strong sales background, for example, might partner with a technical or financial expert to cover several essential aspects of the project.

But complementary skills alone are not enough. Ideally, co-founders should share a compatible vision, level of ambition and commitment to the project. It is also advisable to define everyone's roles and responsibilities clearly from the very beginning.

How to fund your start-up

Turning an idea into a viable business requires more than time and energy: it also requires money. Product development, recruitment, marketing and customer acquisition can all represent significant costs. Fortunately, start-up founders have several funding options, from using their own resources to bringing external investors into the company.

Bootstrapping, Love Money and Personal Equity

Many entrepreneurs start by investing their own money in the business. This personal equity can cover initial expenses such as market research, developing a prototype or launching a website. Founders may also turn to friends and family for financial support, a practice commonly known as love money. These early contributions can help get the project off the ground before professional investors become involved.

Another approach is bootstrapping, which means building the company with little or no external funding. Instead, founders keep costs under control and reinvest the revenue generated by the business to finance its growth. The main advantage is independence: entrepreneurs retain greater control over their company and avoid diluting their ownership. However, growth may be slower, particularly when the business requires significant upfront investment.

Business Angels, Venture Capital and Fundraising

When a start-up needs more capital to accelerate its development, it can turn to business angels. These private investors typically invest their own money in promising young companies in exchange for equity. Beyond funding, they can also provide valuable experience, industry knowledge and professional networks.

At a later stage, start-ups with strong growth potential may seek funding from venture capital (VC) firms. A fundraising round can provide the resources needed to recruit, develop new products, acquire customers or expand internationally. In return, investors receive a stake in the company and may also obtain certain governance rights.

Raising external capital can significantly accelerate growth, but it also means sharing ownership and, to some extent, decision-making power. Founders therefore need to think carefully about how much money they really need, how much equity they are prepared to give up and, just as importantly, who they want around the table as their company grows.

Test, launch and grow your project

Once the project has been defined and the initial funding secured, it is time to put it to the test in the real world. For a start-up, the goal is not to build everything immediately, but to test the offer quickly, learn from early users and improve it before accelerating growth.

MVP, lean start-up method and product-market fit

An MVP (Minimum Viable Product) is a simplified first version of a product or service that includes only its essential features. It allows founders to quickly gather feedback from users without investing too much time and money in a solution that may ultimately fail to meet their expectations.

This approach is part of the Lean Startup methodology, which is based on a continuous cycle of building, measuring, learning and adjusting. The aim is to gradually achieve product-market fit, the point at which the offer meets a genuine customer need well enough to generate strong and sustainable demand. Once this has been validated, the start-up can generally consider accelerating its growth.

Acquisition strategy and first customers

Finding the first customers is a decisive step. Depending on its target audience, a start-up can combine several acquisition channels: direct sales, social media, organic or paid search, partnerships, events, PR or referrals. Rather than trying to be everywhere at once, it should identify the channels that allow it to reach its first users most effectively.

These early customers are particularly valuable: they generate revenue, but they also provide concrete feedback on the offer. Understanding why they buy, what they appreciate and what may be holding them back helps refine both the product and the sales strategy. The next challenge is to turn these initial sales into a repeatable and profitable customer acquisition process, an essential step in moving from an early-stage start-up to a growing business.

Common mistakes to avoid when creating a startup

Creating a start-up inevitably involves a degree of uncertainty. Some mistakes are simply part of the learning process, but others can be anticipated. The first is falling so much in love with your idea that you forget about the customer. A concept may look brilliant on paper without addressing a need that is important enough for users to be willing to pay for it. So keep a cool head, even when you think you have come up with the idea of the century!

Another common mistake is trying to move too fast. Developing too many features, hiring prematurely or spending heavily on marketing before validating the business model can quickly drain the company's cash reserves. On the other hand, spending months trying to achieve perfection before launching the product may give competitors plenty of time to get ahead.

Disagreements between co-founders also need to be anticipated. Responsibilities, compensation, strategy, equity distribution and personal ambitions should all be discussed from the outset. A shareholders' agreement can help anticipate certain situations and establish clear rules between the founders.

Finally, a start-up should not confuse growth with success. Rapidly increasing the number of users or generating more revenue is encouraging, but the business model must also become economically viable. Customer acquisition costs, margins, cash flow, retention and profitability are all key indicators that need to be closely monitored.

Which training to create and grow your startup?

Creating a start-up requires a good idea, but also skills in strategy, finance, marketing, innovation and management. Entrepreneurship training provides these essential foundations while giving students the opportunity to put their projects to the test in real-world situations. EDC Paris Business School offers several programmes designed to help turn an idea into a viable business.

MSc Innovation & Entrepreneurship and the EDCube Incubator

The MSc Innovation & Entrepreneurship is designed for students who want to create their own company, develop an innovative project or become intrapreneurs within an existing organisation. The programme focuses on action, experimentation and market testing. Students learn how to identify opportunities, analyse markets, build robust business models and turn ideas into viable projects.

The curriculum directly reflects the different stages involved in creating a start-up, with courses covering Venture Design & Business Models, Growth Marketing & Digital Strategy, Fundraising & Entrepreneurial Finance, and Innovation Management & Intrapreneurship. The programme is available on a work-study basis, allowing students to apply what they learn to real business challenges.

Project founders can also benefit from the EDCube incubator. It supports students in validating their ideas, structuring their business models, finding funding and preparing for launch. Mentoring, workshops, pitch sessions and meetings with members of the entrepreneurial ecosystem help them develop their projects throughout the different stages of their journey.

The Grande École Programme (Master in Management)

The Grande École Program, a five-year course leading to a Master's degree, provides a broader approach to management. Students progressively develop skills in strategy, finance, marketing, operations and technology, while strengthening their ability to work in teams and manage projects. Entrepreneurship is introduced from the very first year, with a course dedicated to Entrepreneurship and Business Models.

The entrepreneurial dimension becomes increasingly important as students progress, with courses focusing on areas such as innovation and Design Thinking. At Master's level, students can choose an Entrepreneurship & Innovationspecialisation designed to teach them how to identify opportunities, design and test business models and manage projects in uncertain environments. Lean Startup, prototyping, pitching, business planning and fundraising are among the skills developed.

This approach enables students to master the fundamentals of management before developing more advanced entrepreneurial expertise. It is particularly suitable for those who want to create their own start-up, join a fast-growing young company or lead innovative projects within an organisation.

Creating a start-up takes method, perseverance and a strong ability to adapt. From the initial idea to the first customers, every step is an opportunity to test the project, learn and sometimes challenge your own assumptions. After all, entrepreneurship is not about having all the answers from day one: it is about knowing how to keep moving forward despite the questions. And if you truly believe in your idea, don't wait forever for the perfect moment to get started!
