You do not need a large investment or outside investors to start building a business. Many founders begin with savings, side income, preorders, or their first customer payments. This is bootstrapping: using the resources you have to turn an idea into a viable company.
It can give you greater control, protect your ownership, and help you grow on your own terms. But it also comes with real financial risks, and for some founders, it is not a choice at all.
This guide explains how bootstrapping works, when it makes sense, and how to use it without putting your finances or well-being under unnecessary pressure.
What Is Bootstrapping in Business?
Bootstrapping means starting and growing a business primarily with the resources available to you. Instead of selling part of the company to outside investors, founders often rely on personal savings, income from another job, preorders, early sales, and profits reinvested in the business.
For example, a founder might keep freelancing while developing a product, use customer deposits to pay for production, or reinvest the first profits into marketing and new inventory. In many cases, bootstrapping combines several of these funding sources.
However, bootstrapping does not mean building a business without spending money or refusing every form of debt. Some bootstrapped founders use credit cards, small business loans, or financial support from family. The main distinction is that they retain ownership rather than exchanging equity for investment.
Here is how the most common funding approaches compare:
| Funding method | Where the money comes from | What the founder gives up or risks |
| Bootstrapping Savings | Savings, side income, preorders, sales revenue and reinvested profits | Personal capital, financial security and potentially slower growth |
| Personal capital | A bank or another lender | Interest costs and responsibility for repayment |
| Business loan | An individual investor using their own money | A share of ownership and potentially some control |
| Venture capital | A professional investment fund | Equity, influence over decisions and pressure to grow quickly |
No option is automatically better than another. The right choice depends on how much money the business needs, how soon it can generate revenue, how quickly it must grow, and how much financial risk the founder can realistically carry.
Where Does the Money Come From?
Most bootstrapped businesses do not rely on a single source of money. Founders often combine:
- Personal savings
- Income from a job or freelance work
- Early sales and customer deposits
- Preorders
- Support or loans from family
- Small amounts of credit
- Profits reinvested in the business
The aim is usually to start with the smallest workable budget, test whether customers are interested, and use incoming revenue to fund the next stage. Some founders also launch a service first, then use the income to develop a product.
This creates a simple cycle: start small, sell, learn, and reinvest. The following businesses show what that approach can look like in practice.
Only Curls: Starting With One Product and £500
Lizzie Carter launched Only Curls in 2016 after struggling to find suitable products for her naturally curly hair. Rather than developing an extensive and expensive product line, she started with one item: a microfiber hair towel.
Carter and her co-founder invested £500 and reinvested the profits as the business grew. Only Curls later expanded into a complete haircare range without relying on external investment or borrowing. Her experience shows how a focused first product can help a founder test demand before committing more money. The Successful Founder, The Times
Starting small does not mean thinking small. It means allowing real customers to shape what comes next.
BANG! Curry: Turning Skills Into Startup Capital
Dr. Shelly Nuruzzaman reportedly started BANG! Curry with £650 while her family was adjusting to living on one income. With no large pot of money available, she used her existing cooking knowledge and scientific approach to begin testing the idea from home.
Nuruzzaman ran paid cooking classes to conduct market research and raise additional funds. She then sold her curry kits at local markets and reinvested the revenue in the business. This gradual approach eventually helped BANG! Curry secure larger opportunities, including partnerships with HelloFresh and Waitrose.
Both stories demonstrate an important principle of bootstrapping: your first source of capital may not be an investor. It may be one product, one skill, or the first customer willing to pay.

Why Do Founders Choose to Bootstrap?
For many founders, the greatest appeal of bootstrapping is control. Without outside investors, they can make decisions based on their customers, values, and long-term goals rather than pressure to deliver rapid returns.
Bootstrapping can also help founders:
- Retain a larger share of the company
- Choose how quickly the business grows
- Test an idea before making a major investment
- Focus on paying customers from the beginning
- Change direction without seeking investor approval
- Develop careful spending habits
These benefits do not make bootstrapping easy. Limited capital can slow growth and force difficult choices. However, for a business that can generate revenue early, it may provide valuable time to build a strong foundation.
Spanx: Retaining Ownership While Reinvesting Profits
Sara Blakely started Spanx in 2000 with $5,000 from her personal savings. The company was profitable from the beginning, and she reinvested its earnings rather than accepting outside investment.
This allowed Blakely to retain full ownership for more than two decades. In 2021, she chose to sell a majority stake to Blackstone in a deal that valued Spanx at $1.2 billion, while keeping a significant stake herself. Stanford Graduate School of Business, Blackstone
Spanx is an exceptional success story, not a typical result of bootstrapping. Still, it illustrates the value of ownership: when founders build equity gradually, they have more control over whether, when, and under what conditions they bring in an investor.
When Bootstrapping Is Not Really a Choice
Some founders bootstrap because they want to retain control. Others do it because external funding is difficult to access.
Limited collateral, a short credit history, few investor connections, or a business model that does not promise rapid growth can make loans and investment harder to secure. Women entrepreneurs also tend to raise less external capital and rely more heavily on personal savings and other personal resources.
This is why bootstrapping should not always be presented as an inspiring lifestyle choice. Resourcefulness deserves recognition, but celebrating every self-funded business as a triumph can hide unequal access to finance and the additional risk some founders are forced to carry.
Advantages and Disadvantages of Bootstrapping
Bootstrapping can offer valuable freedom, but it also places more risk on the founder.
Advantages:
- You retain ownership and control.
- You can grow at your own pace.
- You focus on customers and revenue early.
- You can make decisions without investor approval.
Disadvantages:
- Your personal savings may be at risk.
- Limited funds can slow growth and hiring.
- You may miss time-sensitive opportunities.
- Managing too much alone can lead to burnout.
The goal is not to bootstrap at any cost. It is to choose a funding approach that supports both your business and your well-being.
Bootstrapping can help you test an idea, retain ownership, and build a business on your own terms. But it is a funding strategy, not a measure of how committed or capable you are.
Start with what you have, protect your personal finances, and reinvest where it can make the greatest difference. If the business eventually needs a loan or an investor to move forward, seeking outside funding is not a failure. The right approach is the one that supports sustainable growth without asking you to carry every risk alone.
