The Big idea: Angel investing is not an individual sport, even when decisions are made independently.

Why it matters: The quality of your circle shapes not only your judgment, but your access to opportunities, your calibration of risk, and the quality of decisions you make.

Angel investing often appears solitary: one investor, one decision, one cheque. That impression is misleading. The most effective angels rarely operate in isolation. They compound advantage through proximity to other investors who think differently, challenge assumptions, surface blind spots, and share pattern recognition early.

The highest-quality diligence I’ve been part of came from mixed investor backgrounds from completely different walks of life and experiences. What one person misses, another reliably catches.

Early-stage investing is defined by incomplete information. No individual, regardless of experience, has full visibility. The investors who perform best acknowledge this constraint and design around it. They do not attempt to see everything themselves; they build networks where insight, deal flow, and risk assessment are distributed and continuously refined.

One of the strongest due diligence processes I’ve seen took place during a live case study on one of our courses — on a healthtech company, where a politician, a TikTok entrepreneur, a doctor, a McKinsey consultant, and an entrepreneur evaluated the business together. The breadth of perspective transformed the depth and quality of the analysis in a way no individual investor would have been able to.

Every investor has blind spots. Some are technical; others are behavioural. Left unexamined, they become costly.

Strong investing circles surface blind spots before capital is committed. Someone challenges an assumption you did not realise you were making. Someone recognises a pattern you have not yet seen. Someone brings context you lack.

A single perspective narrows decision quality.

Multiple perspectives reduce error.

High-quality investor circles do not exist to validate thinking; they exist to stress-test it.

They require you to articulate why a deal works, not merely why it sounds compelling. They apply pressure before conviction hardens into bias. This debate and diversity of thought are productive; they sharpen reasoning and expose weak assumptions while they are still inexpensive to correct.

If your thinking is never challenged, it is not being refined.

High-quality deal flow is not random; it moves through trust.

Founders share opportunities with investors who ask rigorous questions and behave predictably. Angels share deals with peers whose judgment they respect. Over time, access concentrates around those who are prepared, thoughtful, and consistent.

Deal flow is not luck.
It is reputation, accumulated over time.

Some of my best deal flow as an angel investor has come from founders I’ve already backed, who recommend me to other founders as the kind of angel they should want on their cap table. 

Angel investing has a steep learning curve. Exposure shortens it.

Observing how others evaluate founders, assess risk, and make trade-offs accelerates judgment formation. Patterns are internalised without each lesson being learned in isolation, resulting in a more reliable internal compass over time.

Confidence built in isolation is fragile.
Confidence built through exposure endures.

Belonging does not remove responsibility; it reinforces it.

You gather perspective. You weigh arguments. You decide. The objective is not consensus, but higher-quality information before commitment. Strong investors remain accountable for their decisions while benefiting from shared insight.

Independent thinking does not require isolation.
It requires discipline.

Angel investing rewards those who design for uncertainty. The strongest investors do not attempt to out-think the market alone; they build environments that challenge assumptions, surface risk, and improve signal quality.

No one wins alone in this asset class.
Those who recognise that tend to stay in the game longer.
