The Homophily Trap: Why “Culture Fit” Keeps Capital in the Same Rooms

Change who’s in the room. Change who walks through the door.

There’s a specific sound an investor makes when they recognise themselves in a founder.

It’s not a word exactly. It’s a lean forward. A change in pace. The moment they stop taking notes and start asking follow-up questions. The energy in the room shifts, and everyone in it can feel it.

I’ve watched it happen. I’ve watched it not happen.

Same founder. Different rooms. Wildly different energy because of what the investors brought into the room before she opened her mouth. Their own references. Their own shortcuts. Their own mental image of what a fundable founder looks and sounds like.

That invisible image has a name.

It’s called homophily. And it is quietly compounding into one of the most expensive problems in venture capital.

What homophily actually is

Homophily is the tendency to trust, associate with, and ultimately back people who feel familiar. It’s one of the most well-documented patterns in human behaviour. In friendships, in hiring, and in capital allocation.

In venture capital, it looks like this: investors fund founders who remind them of themselves. Not because those founders are objectively better. Because familiarity registers as competence.

Calder-Wang and Gompers put it plainly: “Venture capitalists prefer to hire, invest in, or co-invest with those that are similar to themselves in characteristics such as gender and ethnicity.”

Not “might prefer.” Not “show some tendency toward.” Prefer.

Richard Kerby, a Partner at Equal Ventures, named the outcome with a word that has stayed with me:

“This industry feels less of a meritocracy and more of a mirrortocracy.”

A mirrortocracy. An ecosystem that funds the founders who mirror the people writing the cheques.

The Spotify problem

Think about your music algorithm.

When you first opened the app, it learned from what you played. Then it played you more of what it thought you liked. Then you played that. Then it confirmed its own assumptions. You ended up in a loop of what you already knew and the algorithm never had a reason to break you out of it.

That’s by design.

Now apply that logic to venture capital.

An investor makes their first ten investments. They look for founders who feel familiar. Who sound like the people they went to university with. Who pitch with the cadence and confidence of someone who grew up in rooms like theirs. Those investments either work or don’t. The pattern cements. That becomes the profile.

The algorithm isn’t malicious. It’s just math. But what it misses might be extraordinary.

---

The numbers don’t lie

Here’s what that algorithm produces at scale.

A paper published in the Cambridge Journal of Economics in March 2026, just weeks ago, analysed a decade of UK AI venture capital:

• 95.5% of VC decisions were made by majority-male teams

• All-female-founded AI startups raised just 0.8% of total capital invested

• In AI hardware specifically, not a single all-female-led startup received funding across the entire period

And yet the returns data tells a completely different story.

Female-founded companies generate 78 cents of return for every dollar invested, compared to 31 cents for male-founded teams (BCG and MassChallenge, 2018). First Round Capital’s own ten-year analysis found investments in startups with at least one female founder performed 63% better than all-male founding teams.

The market is systematically underinvesting in the better-performing asset class.

That is a returns problem.

And here’s what compounds it further: Harvard Kennedy School research found that homophilic syndication; VCs investing alongside others who are similar to them, is associated with a 20% or greater reduction in the probability of a successful exit. The bias is destroying value. Capital is being left on the table by a system built to protect itself.

The Australian numbers

Here in Australia, the headline tells one story and the data tells another.

Cut Through Ventures, State of Australian Startup Funding report, highlights that in 2025 the startup ecosystem raised $5.1 billion. The third-biggest funding year on record. Teams with at least one female founder captured 24% of that, the strongest result since 2019. On the surface, progress.

But deal participation for those same teams actually fell—from 28% to 24%. The capital was concentrated in the top five deals, which accounted for 79% of everything allocated to teams with at least one female founder.

The other 87 such companies split just $257 million between them.

One company, over two rounds, is actually doing most of the heavy lifting. Airwallex, founded in Melbourne and now headquartered in Singapore and San Francisco, raised a combined $730 million across a Series F and Series G in 2025. It is counted as Australian in this report.

It is co-founded by Lucy Liu, who at 25 wrote a $1 million personal cheque to back the company she’d go on to help build into a global fintech, became its President, and has since been named among Fortune’s Most Powerful Women in Asia. She is, by any measure, one of the most remarkable women in Australian tech.

Airwallex raised more capital in a single year than every other mixed-gender (at least one female founder) founding team in Australia combined. The headline moved because one deal moved. That is not the same thing as progress.

All-female founding teams, approximately 8% of deals, raised $102 million across the entire year. 2% of total capital. Down from 4% the year before.

Only 18% of female founders said they feel supported by their investors.

The headline improved. The structural problem did not.

The innovation gap nobody’s pricing in

We are in the middle of an AI boom. Venture capital is the engine powering it. And the people deciding which AI companies get funded are, by and large, the same people who have always decided.

A new Oxford paper frames this with a term I think should become part of our standard vocabulary: male-lens investing. Not just bias. A lens. A set of filters built into the structure of investment decisions, shaping not just who gets funded, but what gets built.

When the people funding AI are predominantly men from similar educational and social backgrounds, investing in founders who look like them, the result isn’t just an unfair funding gap. It’s AI built from a narrow slice of human experience and then deployed into the entire world.

We’ve seen this before. Medical devices calibrated for male physiology. Voice recognition that couldn’t understand women’s voices. Seatbelts designed for the male body. All built by teams who couldn’t see the gap because they weren’t in it.

The innovation gender gap isn’t just about who gets funded. It’s about what gets invented. And who gets left out of the future being built right now.

The flywheel that keeps it spinning

Homophily is persistent because it isn’t a one-time bias. It’s a flywheel.

Male investors fund male founders. Those founders exit, accumulate capital, and become the next generation of angels. Those angels fund the founders who look like them. The cycle continues. It does not naturally correct.

According to La Fosse, women make up just 13% of VC investment committee decision-makers — the people with actual authority over where capital goes. In 66% of investment teams, there are no women at that table at all.

I’m not planning to wait for that to change on its own.

The complication — and why it matters

I want to stop here. Because the research contains a finding that complicates the simple “add women to fix it” narrative. Pretending otherwise would be intellectually dishonest.

Snellman and Solal (2023) found that female founders who received funding from female VCs were twice as likely to struggle with follow-on financing than those funded by male VCs. The mechanism isn’t founder quality. It’s signal interpretation. The broader, predominantly male market reads a female-backed female-founder pairing as social endorsement rather than rigorous merit assessment. As the authors put it: “well-intentioned calls for women to invest in women not only place an undue burden on female investors, but may also undermine the long-term success of female entrepreneurs.”

That’s a confronting finding. But it carries a qualification that rarely makes it into the headline.

It is specific to institutional VC. The conformity pressures, fund mandates, and career incentives inside formal VC firms are what generate the paradox. An institutional investor risks reputational capital when they visibly champion female founders. An angel investor writes a personal cheque with their own money, under no mandate, accountable to no LP. The incentive architecture is fundamentally different.

In the angel context, the data tells a different story.

UK angel groups with more than 15% women investors allocated 21% of their capital to all-female founding teams—three times the rate of groups below that threshold. By 2024, 49% of female angel investment in the UK went to women-led businesses, compared to just 19% of male angel investment.

UNSW Business Think research found that 39.5% of female-led firms received early-stage funding, compared to 25.9% of male-led firms. The same researchers found that at Sydney Angels specifically, a structured group evaluation model—where every investment assessment must be explained and defended to the group—helped surface and interrupt implicit bias in real time. Design matters more than intention.

Women-led angel groups also attract more applications from women founders in the first place. Change who’s in the room, and you change who walks through the door.

The angel stage opens that door. Series A and beyond, which is still overwhelmingly male-dominated, is where the paradox re-emerges. That gap between first cheque and follow-on capital is the real structural problem. It requires two things to close: investment infrastructure operating by different rules, and enough scale within that infrastructure to carry companies further before they have to re-enter a system that wasn’t designed for them.

What actually breaks the pattern

You can’t fix homophily by trying harder. Willpower won’t move it, because it was never a conscious decision. What moves it is structure.

Standardise the process. If different types of founders receive fundamentally different questions, you’re scripting the outcome before the pitch begins. Measure it. Name it. Change it.

Diversify investment committees. Not tokens. Decision-makers with real authority, real carry, and the institutional power to challenge a deal that fails on merit rather than familiarity.

Track your own question patterns. If you’re not measuring it, you can’t see it. And if you can’t see it, you’ll call it instinct.

Proactively source outside your default network. Research shows 90% of VC deals come through existing networks. If the network is homogeneous, the deal flow will be too. This is not complicated. It just requires intent.

Build women-only investment structures. Deliberately. This is not separatism. It’s evidence-based design. Research by Cohen, Bellavitis and Wirtz (Journal of Corporate Finance, 2025) found that female angels invest with greater conviction, higher frequency, and more attention to female founders in women-only structures than in mixed settings. Harrison, Botelho and Mason (2020) documented the inverse: women in majority-male angel groups make fewer investments, contribute less, and engage less robustly in deliberation. The same woman. Completely different behaviour. Different room, different outcomes.

The conversation that stopped me

Last night I was at dinner with a VC team. Genuinely good people. Strong values. Excited about what I’m building — the idea of creating a channel that feeds educated, experienced female investors into the VC pipeline, directly addressing the homophily problem at the source.

Then one of them said something that took me aback.

“We’re still struggling to find great women founders.”

They weren’t making excuses. They were genuinely frustrated. Exasperated, even.

I sat with it for a moment. And then I said: I wonder if we’ve told the 2% story so loudly, and so well, that women founders have simply stopped knocking on VC’s doors.

Because here’s the thing. The data on where women are taking their capital when they do build is striking. Women are actively routing around VC. They’re outperforming men on crowdfunding platforms by 32%. Revenue-based financing providers report significantly higher approval rates for female founders. They’re bootstrapping, taking grants, seeking debt. It’s not because they lack ambition. It’s because the signal coming from the VC ecosystem has been, for years: this room wasn’t built for you.

Yale SOM research found that women are 18% less likely to seek VC for their next venture even after a successful exit. Not after failure. After winning. The room is so unwelcoming that succeeding inside it doesn’t make women want to go back.

So when a VC with good values and genuine intent tells me they can’t find great women founders — I believe them. And I think the system is, in part, experiencing the consequence of its own design. We’ve been telling a story of exclusion so effectively that it may have become self-fulfilling. The founders who might have knocked are building something different instead. Somewhere the maths looks better.

We cannot solve that by adding “apply here” buttons to pitch portals. We solve it by building investment infrastructure that doesn’t carry twenty years of you probably won’t make it in its walls.

That’s what Vested Angels is built to do. Not to patch the existing architecture. Instead, to build a different one, making sure the door is visible to the founders who stopped believing one even existed.

Change who’s in the room. Change who walks through the door.

Vested Angels is an angel syndicate for women ready to move from reading about the gap, to doing something about it. If that’s you, I’d love to hear from you.
