hen people think about building a career in VC, they often focus on investing in successful companies or joining a top-tier firm. And it's true - deal flow and firm brand matter. But there's another critical component that can be often overlooked: in VC, your reputation travels fast.

Venture capital is a relatively small industry. By the end of 2024 the entire US ecosystem had about 3,417 firms* and about 6,175 open positions. Compared to the tech industry, VC is tiny. This means, the ecosystem is pretty intimate. Your partners, GPs and founders likely know each other, or know someone who knows them. 

This interconnectedness means everything you do becomes visible. How you source deals, work with founders, and add value - all of it becomes part of your career capital. A strong portfolio at one firm gets noticed at others. A pattern of supporting founders through tough times becomes recognized across the ecosystem. But this also means that  mistakes or difficult interactions can follow you too.

One way to illustrate this: imagine you've helped a founder through a difficult pivot, going beyond your role to make real connections that saved their company. That founder attributes part of their success to you in an interview. Their co-investors notice. Suddenly, you're getting intros to better deals because people know you actually add value, not just capital.

So what does this mean for building your career in VC?

The usual advice focuses on getting into a brand-name firm or backing potential unicorns. But given how small and interconnected this industry is, there's something at least as important: consistently showing up as someone founders want to work with and partners want to invest alongside.

Your reputation compounds. Every founder interaction, every interview, every way you handle a down round - it all adds up. In a small industry, your track record can be a valuable asset or big liability. 

Most venture capitalists struggle with volume and noise in their founder pipeline. Having a clear public voice filters in founders who match the investor’s perspective, and allows the investor and the founder to begin the conversation far further downfield. Founders attach to specific people, not institutions. This makes an investor’s public persona an asset or a liability to the firm’s top of funnel.

Public Persona as sourcing infrastructure

Success is not measured by ten thousand views. Success is measured by whether the one founder you wanted to reach actually saw the piece. When you present yourself online with specificity, rather than safe generalities, you may repel a lot of people, but you attract better fit people faster. Ambiguity feels safer, but slows matching. It is better to be unmistakable to the right few than acceptable to everyone. Founders discover and evaluate investors through online communities, operator networks, social platforms, podcasts, interviews, and circulating ideas. A consistent public voice builds familiarity and credibility.

Founders judge investors by their digital selves

With more AI native founders and an increasingly online-first founder ecosystem, your digital identity is treated as the real version of you. A founder may never meet you in person, but they develop a clear sense of your worldview, temperament, and values through your posts, interviews, essays, and public interactions. In the very early stages, founders want an investor they feel they know well, who stands by their convictions, and whose ideas speak to their lived experience, their market, and their ambition. The digital version of you becomes their first impression and a meaningful filter.

Publishing refines your judgment

Publishing forces clarity of thought. When you articulate an idea in public, you commit to it, refine it, and expose it to scrutiny. This creates a higher internal standard for your thinking. Instead of vague instincts or half formed theories, you are required to sharpen your logic, your frameworks, and your point of view. Good content becomes a form of disciplined journaling with consequences, which is why it consistently improves investor judgment and decision making. It is a reflective practice that makes you a clearer thinker, a sharper evaluator of teams, and a better partner to founders.

Sarah Guo (Conviction, formerly Greylock) and thinking in public

Sarah Guo used multiple public channels as a living notebook for her investment thinking over the last decade. Long before she started Conviction, and long before every VC was an AI futurist, she was publishing, speaking, moderating, and interviewing around her interest areas at high velocity. Her Greylock Perspectives posts tracked her enterprise and infra investments. She moderated discussions with Andrew Ng, Eric Yuan, Bret Taylor, and Aaron Levie. As early as 2015, she was publishing reflections on founder psychology on her Medium account, and later longer theses such as “The Conversational Economy, Voice and the New Era of Multi Modal Computing” (on how voice interfaces, ambient computing, and multimodal interactions would reshape distribution, workflows, and software architecture), and “Is There a Pony in There, Five Steps to Diligence Your B2B Startup Idea” (a detailed, structured game plan to validate enterprise ideas.)

She became a recurring voice in cybersecurity, future of work, and deep tech events. Her content circled consistent themes, including infrastructure, workflow complexity, security, developer experience, and software that learns from data. She was already publicly thinking about the domains ripest for AI long before she called herself an AI investor. She built a visible intellectual profile and became known as an enterprise native thinker with strong frameworks, predictions, and founder empathy.

When she left Greylock and launched Conviction in 2022, her earlier decade of content cohered into a clear AI thesis. Her launch narrative and her publicly shared LP letters focused on Software 3.0, meaning systems where intelligence is the primary engine, where products learn automatically, and where defensibility comes from data loops and infra advantage. The name Conviction signaled willingness to make concentrated early bets, often pre product but not pre insight.

Her podcast No Priors, co hosted with Elad Gil, acted as an accelerant. With more than one hundred episodes, it positioned her as both interviewer and interpreter of the AI frontier. Weekly conversations with researchers and founders created a high frequency distribution flywheel for her thinking. Combined with her decision to publish LP letters openly, each episode and memo became another building block in the intellectual architecture she started years earlier.

Her X and LinkedIn presence mirrors that tone. She posts crisp insights on model capabilities, agents, defensibility, founder taste, enterprise GTM, and infra economics. Her posts echo her early Medium voice, meaning direct, unambiguous, slightly contrarian, and grounded in technical reality. Fortune profiled her in 2025 as a leading AI investor. Her reputation was not a sudden creation. It was the result of a decade of consistent, high-specificity public thinking across essays, frameworks, interviews and open memos.

What to Watch Out For

Being opinionated does equate being brash or insensitive for the sake for virality or attention. Tone matters. Founders read values through language, not just content. In venture, there is no true “personal” social media account. A partner’s political, cultural, or value driven posts are interpreted as signals of the firm. These signals affect dealflow, founder trust, LP confidence, and internal culture.

Founders perform diligence on the values a firm and partner represent. Many quietly screen investors for alignment on ethics, worldview, and cultural compatibility. Misalignment can kill a deal before anyone reaches the first meeting. Institutional LPs also monitor partner behavior. A single partner’s online activity can become a fund level risk factor. Negative or inflammatory posts travel instantly through founder communities, usually through screenshots shared privately. Firms would benefit from internal alignment on online conduct – not to suppress individuality but to ensure communication is consistent with the firm’s identity and with founder expectations.
