What is a startup and how does it get funding?

A startup is an early-stage business developing an innovative, repeatable and scalable business model under conditions of uncertainty. Rather than simply opening a business in an established market, a startup aims to solve a problem in a new way and build a model that can grow significantly without costs increasing at the same rate.

Understanding what a startup is involves more than knowing how to launch a business. Founders must test customer demand, refine their products, manage cash flow and make strategic decisions before they have a proven route to profitability.

For professionals interested in developing these skills, the Master in Business Administration at Universidad Europea covers areas including finance, business strategy and product development, which are relevant to managing a growing organisation.

What are the main characteristics of a startup?

Startups share several characteristics that distinguish them from businesses operating with established models.

• Innovation means introducing a new solution or significantly improving an existing product, service or process.
• Scalability allows a business to increase its customer base and revenue without a proportional rise in operating costs.
• Uncertainty means founders test assumptions about customer needs, pricing and demand before they know whether the business model works.
• Agility enables small teams to change their product, target market or strategy in response to customer feedback.
• Growth orientation places emphasis on validating the business model and expanding its reach, often before achieving consistent profits.

A technology company developing a subscription platform for small businesses is one example. If the platform attracts customers across multiple markets without requiring a separate service team for every customer, it has the potential to scale.

However, not every new business is a startup. A new local café, for example, can be a successful business without pursuing an innovative, repeatable model designed for rapid expansion.

The main difference is that a startup searches for a business model that works, whereas an established business generally focuses on executing and improving a model that has already been validated.

These are general distinctions rather than fixed rules. A traditional business can innovate rapidly, while a startup can prioritise profitability over expansion.

The key difference is the management challenge. Startup founders must establish whether their assumptions are correct, while leaders of established businesses concentrate on improving performance, controlling costs and maintaining reliable operations.

What are the main stages of a startup?

Startups typically progress through five stages, from identifying a problem to expanding a validated business model. The process is not always linear, and businesses often revisit earlier stages when customer feedback challenges their assumptions.

Pre-seed stage

Founders identify a problem and investigate whether a viable market exists for a proposed solution. They research potential customers, competitors and pricing before committing substantial resources to product development.

A business model canvas helps organise assumptions about customer segments, value propositions, revenue streams, costs and distribution channels.

Seed stage

The team develops a minimum viable product (MVP), a basic version of the product that allows it to test its core value proposition with real users.

The priority is learning whether customers need the solution, use it and are willing to pay for it. Feedback informs product improvements and future investment decisions.

Early growth

Once the business demonstrates evidence of demand, the team works to acquire customers and improve retention. It tracks metrics such as customer acquisition cost, recurring revenue and churn, which measures the rate at which customers stop using a service.

At this stage, founders assess whether the business can grow without its costs increasing disproportionately.

Expansion

A startup with a validated model can enter new markets, develop additional products or increase its customer base. Hiring, operational processes and management structures become increasingly important as the team grows.

Maturity

The business develops more established processes and focuses on sustainable performance, profitability and long-term strategy. Its structure can begin to resemble that of a traditional company.

How do startups secure funding?

Startups use a combination of founder investment, external investors, lending and other funding routes, depending on their stage of development and financial needs.

The main options include the following.

• Bootstrapping involves funding the business through personal savings and revenue generated by its operations. It allows founders to retain greater ownership but limits the resources available for growth.
• Business angels are individuals who invest their own money in exchange for equity. They can also provide industry knowledge, mentoring and professional contacts.
• Venture capital involves investment funds providing capital to businesses with significant growth potential in exchange for an ownership stake.
• Incubators and accelerators offer structured support, mentoring and access to networks. Some programmes also provide funding in return for equity.
• Equity crowdfunding allows a business to raise capital from multiple investors through a platform in exchange for shares.
• Public funding includes grants, loans and other support schemes, subject to eligibility requirements.

Investment rounds are often described as seed, Series A, Series B and subsequent rounds. Each round typically reflects the company's development and capital requirements. Founders must consider equity dilution, which reduces their percentage ownership when new shares are issued.

External investment is not essential for every startup. The appropriate funding route depends on the business model, growth objectives, cash flow and willingness to share ownership.

What skills does a startup founder need?

Startup founders need a combination of commercial, financial and leadership skills to turn an idea into a sustainable business.

The most important skills include strategic thinking to define priorities, financial management to control spending and forecast cash flow, and market research to establish whether a product solves a genuine customer problem.

Founders also need to interpret performance metrics, negotiate with investors, recruit employees and communicate a clear business vision. As the company expands, delegation and team management become increasingly important.

These skills are relevant beyond entrepreneurship. Professionals leading innovation projects or managing established organisations also need to assess opportunities, allocate resources and make decisions under uncertainty.

Developing a structured understanding of business strategy, finance, marketing and people management helps professionals connect day-to-day decisions with longer-term commercial objectives.

Building a startup is ultimately a process of testing assumptions, learning from evidence and developing a business model that can sustain growth. Understanding its stages, funding options and management requirements provides a practical foundation for anyone considering entrepreneurship or a leadership role in a growing company.
