Why behavioural finance matters to a first-time founder
Behavioural finance applies insights from psychology and behavioural economics to financial decisions and markets. It examines how limited attention, emotion, social influence and mental shortcuts can affect investing, fundraising and budgeting. The point is not that people are simply irrational, but that judgement can shift in predictable contexts.
Examples of behavioural finance
After a Johannesburg start-up’s valuation rises from ZAR 20 million to ZAR 60 million, its founder treats that recent figure as the minimum acceptable value despite weaker sales. This anchoring, meaning relying too heavily on an initial reference point, delays a viable funding round and leaves the company with two months of cash.
Common misunderstanding
Behavioural finance is not a licence to dismiss every surprising market move as a bias. Prices can change because information, risk or liquidity changes. A bias is also not a diagnosis of a person’s character. Good analysis compares behavioural explanations with financial evidence and considers whether incentives or missing information better explain the decision.
When to use it
Use behavioural finance when reviewing investment choices, forecasts, fundraising expectations or reactions to gains and losses. Write decision criteria before seeing outcomes, invite independent challenge and compare scenarios. These safeguards reduce avoidable errors, but they do not remove uncertainty or replace financial, legal or investment advice.
US spelling: behavioral finance.
