External capital can fund expansion, strengthen the balance sheet, open new markets or let a business seize opportunities that would otherwise take years to reach.
But equity is not a loan. An investor doesn’t just provide money. They acquire an economic interest in the business and often a voice in important decisions.
So the first question isn’t how much you can raise. It’s what problem external capital will solve that the business cannot solve efficiently on its own.
Capital should ideally accelerate a business that has something worth accelerating. If the answer is a clear growth opportunity, you are raising from a position of strength. If the business simply needs money to survive, terms, valuation and negotiating leverage all tend to move against you.
Why founders bring in capital
Founders commonly raise capital for three reasons:
- Growth: funding capacity, technology, market access or expansion
- Strategic: gaining relationships, expertise, distribution or networks
- Liquidity: realising part of the value built in the business, usually through a secondary sale of existing shares rather than new money entering the company. This serves the founder’s position rather than the business’s needs.
Not all investors are the same. A financial investor typically brings capital and governance discipline. A strategic investor brings capital too, along with distribution, technology, customers or market access.
Consider the alternatives first
Equity is only one way to fund a business. Before raising it, ask whether the need could be met by retained earnings, bank debt, asset finance, supplier or customer terms, or grants.
Each option has limits. Debt requires dependable cash flow to service it, and some opportunities are too risky or too large for lenders. But equity is a permanent claim on the future value of the business, so it is often the most expensive capital if the business succeeds. It should be chosen deliberately, not by default.
What you give up
Founders often focus on the cheque and underestimate the terms. Three things deserve attention:
- Ownership and valuation: the valuation sets how much of the business you give up for each unit of capital. A lower valuation means more dilution for the same money, and the effect compounds with every later round.
- Decision rights: investors commonly seek board seats and approval rights over matters such as budgets, new debt, senior hires, new share issues or a sale of the business.
- Information and exit expectations: expect regular reporting, and expect investors to want a route to a return, whether a sale, a buyback or a later transaction. That can shape your timeline.
When raising capital may be premature
A growing business isn’t automatically ready to raise capital. Investors will want to understand the business model, financial performance, governance, ownership, management, risks and future opportunity. If these are unclear internally, raising capital can create pressure before it creates value.
Common warning signs include:
- Operations, relationships or key decisions that depend entirely on the founder
- Financial information that is late, unreliable or hard to reconcile
- An unclear ownership structure or informal shareholder arrangements
- No board, advisers or defined governance
- Needing money to cover ongoing losses or ordinary operating expenses rather than to fund a specific opportunity
That last point matters most. Giving away significant ownership merely to keep the business running can limit your options later.

Consider, as a hypothetical, a founder who sells 30% of the company to cover a working-capital squeeze. Two years later, a genuine expansion opportunity appears, but the founder now has less equity to offer, a new shareholder to consult, and less flexibility to move quickly. A cheaper bridge, or fixing the cash cycle first, might have preserved the choice.
What you give up
Before approaching investors, look at the business from their perspective:
- The investment proposition: exactly what the capital will enable and how it will create more value than it costs
- The economics: revenue, margins, cash flow and what drives profitability
- The ownership structure: who owns what, and what happens when new equity is issued
- The governance structure: how major decisions are made
- The management structure: whether the business depends entirely on the founder
Know what you want before you negotiate
Different goals lead to different transactions. Do you want to retain control, or bring in a minority partner? Is the purpose to fund a major expansion, create liquidity, or prepare for a larger transaction later? Do you want a board, or a strategic partner?
Clarity about the outcome should come before the negotiation.
So, when is the time?
There is no universal date, but there is a useful test. The time is right when you can say in one sentence what the money will do and why it will return more than it costs, when alternatives have been considered, and when the business could withstand an investor’s scrutiny without surprises.
Thinking about bringing in an investor?
External capital can accelerate growth, but the right transaction begins with a clear view of your business, ownership, governance, and long-term objectives.
