Should you bootstrap or raise investment?

It depends far less on ambition than people assume and far more on whether the business has a structural reason to need capital before revenue — and on what you actually want the business to be.

What raising investment is genuinely for:

Buying time before revenue, where the product takes years to build or requires regulatory approval.

Winning a market where being first at scale matters — network effects, winner-takes-most dynamics.

Funding losses deliberately to capture share.

Capital-intensive requirements — manufacturing, hardware, infrastructure.

What it costs, beyond dilution:

A commitment to a growth trajectory. Equity investors need a large exit, so a business that could be a comfortable, profitable £2m operation becomes unacceptable once it has taken money that requires a hundredfold return. This is the least understood consequence — you have not just sold shares, you have committed to a particular ending.

Governance, including board seats, consent rights and reporting.

Time. Fundraising consumes months of founder attention, repeatedly.

Terms that bite later, particularly liquidation preferences, which determine who gets what in a modest exit — and modest exits are the common case.

What bootstrapping gives you: control, freedom to choose the pace, the ability to sell whenever you like at whatever price suits you, and a discipline that shows up in the numbers because customers fund you rather than investors.

What it costs: slower growth, personal financial risk, the opportunity cost of a market moving without you, and the hard limit that some businesses simply cannot be built this way.

The middle paths, which are underused:

Revenue-based finance, repaid as a share of revenue.

Debt and asset finance, where there is security and predictable cash flow.

Grants, which are non-dilutive.

Customer-funded development, where a client pays for what you were going to build.

Raising later and smaller, at a higher valuation with more leverage.

The honest question: what do you want in ten years — a large exit, or an asset that pays you?
