Cold Email Produces Better VC Returns Than Warm Intros. Here Is the Research.

The startup fundraising world runs on warm introductions. Founders spend weeks cultivating mutual connections. Accelerators sell access to their networks as much as their advice. The implicit message is clear: cold outreach doesn't work, and if you don't have connections, you should get some.

This conventional wisdom is wrong. And now there's data to prove it.

The Research

Anthony W. Richardson, founder of VentuRank, conducted a systematic study of cold deal flow versus warm deal flow in venture capital. His methodology: he cold-emailed 187 venture capital firms specifically to research their attitudes about warm introductions — and then analyzed their investment data.

The finding that upended the conventional wisdom:

Cold deal flow companies, when they do convert, produce higher returns than warm deal flow companies.

The cold deal flow group had more "noise" — more companies that reached out cold but didn't make it to the investment committee. But the ones that did convert outperformed the warm-intro cohort on returns.

Richardson's conclusion: venture capital firms should abandon warm introduction requirements — not just for diversity and inclusion reasons, but because it is financially irrational to filter out the cohort that produces better returns.

Why Cold Deal Flow Might Outperform

The research doesn't definitively prove causation, but there are plausible explanations:

Selection effect. A founder who cold emails 150 investors, gets ignored by 145 of them, and still closes a round is a founder who has already demonstrated resilience, resourcefulness, and the ability to sell against rejection. These are traits that correlate with company-building success.

Network independence. A company that raises without warm introductions is, by definition, not dependent on any particular network's approval. It may be reaching a market or solving a problem that the established network doesn't naturally surface.

Founder quality signal. Writing a cold email that converts requires the same skills as enterprise sales: research, personalization, concise value proposition, handling objections. Founders who can do this well in fundraising often do it well in sales.

Underpricing. Warm-intro deal flow is heavily competed. When every VC in a network hears about the same company at the same time, valuations get bid up. Cold deals, sourced independently, often close at more rational valuations.

The Warm Intro Premium Is Real — But Misdirected

None of this means warm introductions are useless. The conversion rate data is stark:

• Companies with no introduction have approximately a 1.2% chance of reaching an investment committee
• Warm-intro companies have significantly higher odds

Warm introductions work because they shortcut the trust-building process. They're a co-signer — someone the investor trusts is saying "this founder is worth your time."

But "worth your time" and "worth your money" are not the same thing.

The warm intro system optimizes for access to meetings. The Richardson data suggests it does not optimize for investment returns. VCs who rely exclusively on warm deal flow are selecting for companies that are well-networked, not necessarily companies that are best-positioned to succeed.

The Shifting Landscape

Multiple VCs and observers now state publicly that the requirement for a warm introduction is "slowly dying."

Jason Lemkin (SaaStr Fund) has funded Talkdesk, Salesloft, Pipedrive, Logikcull, Algolia, and Mangomint from cold emails. His portfolio's collective value runs into the tens of billions of dollars — all from inbound cold outreach.

OpenVC was founded specifically to create a public directory where founders can cold-email VCs directly without an introduction. Hundreds of VCs have opted in, explicitly signaling openness to cold outreach.

Several prominent VCs have published blog posts arguing that the warm intro requirement is bad for diversity (it privileges founders with pre-existing network access, which skews toward white men from elite universities) and bad for returns.

What This Means If You're a Founder Without a Network

The data gives you permission to act.

You are not at a structural disadvantage because you don't have warm intro access. You are at a conversion rate disadvantage — cold emails convert at lower rates than warm intros, so you need to send more of them. But the disadvantage is quantitative, not categorical.

Send more emails. Make each one better. Research the investor before you write. Lead with your strongest signal. Make the ask small. Follow up with new information.

The founders who raised from cold emails didn't have better networks. They had better emails — and they sent more of them.

The research says the ones that convert produce better returns. That's not a consolation prize. That's a structural advantage hiding in plain sight.
