How Writing Every Day Got Me Into 50+ Top-Tier Startups

The Three-Year Compounding Loop Between Media and Venture

Three years ago I started writing on Substack. Everything changed from there

I didn’t have a master plan, just a habit of putting my thinking on product, founders and venture into the open, one post at a time.

What began as a newsletter slowly compounded into an audience, the audience compounded into relationships and those relationships compounded into new opportunities.

Today the writing and the investing are inseparable. My channels are the value-add I bring to the companies I back and I wouldn’t have access to many of those companies without the channels. Later it became my thesis.

Venture capital is going through a structural shift. Capital has been commoditized and money on its own no longer wins the best deals. To get into a competitive round you have to bring something the founder genuinely needs and increasingly that something is distribution. Building a product has never been faster or cheaper, so the market is crowded and noisy and getting heard has become the hard part.

I built my model around exactly this. My large-scale, founder-centric media platforms are a proprietary distribution layer that I put to work for the companies I back. Over three years it turned into 50+ investments, most of them next to top tier funds.

1. Why the VC Market Is Structurally Broken

Over the past decade, venture returns have become increasingly concentrated. A small number of top-tier funds consistently capture a disproportionate share of the outcomes, while the majority of funds compete for a much smaller slice of the value, often fighting over lower-quality opportunities.

The dynamic is driven by a simple structural imbalance:

• Capital has become abundant.

• Truly exceptional founders and companies remain scarce

When the scarce resource is the founder and not the money, the power flips. The best founders are now in a position to choose their investors rather than the other way around, and in that world brand and distribution become the primary drivers of access.

Firms like a16z, Sequoia, Founders Fund, Accel and Index Ventures keep winning allocations not only because of the capital they provide, but because they offer a differentiated value proposition on top of it.

a16z made this explicit by building a media and distribution layer around its capital, positioning itself as a launch partner rather than simply a financial backer. They just published a wrap up of their first year into new media. Read it here!

That reframes the whole competitive landscape.

Venture is no longer only about deploying capital efficiently. It is increasingly about controlling access, attention and narrative and the firms that understand this are the ones quietly winning the rounds everyone else only reads about.

2. The Three Pillars of My Distribution Engine

If capital is commoditized, then access has to be earned through distribution.

So I focused on building large-scale, founder-centric media with global reach, designed to consistently attract high-quality founders, operators and investors. The distribution layer rests on three pillars:

1. Daily newsletters

2. A large social presence (Linkedin)

3. Recurring interview series with some of the most relevant operators and investors in tech

Newsletters, roughly 1M views per month combined:

• Product Market Fit: 77k+ readers, 350+ posts published

• AI Market Fit: 43k+ readers, 100+ posts published

Brands that have sponsored the newsletters include Attio, Framer, Deel, Polymarket, Evertrace, Nova and Granola.

Linkedin Profile: 250k+ followers, generating 2 to 4M impressions per week, a direct and recurring touchpoint with the ecosystem

Interview series, direct and on-the-record conversations with leading founders and investors, including:

• Staffan Helgesson, Co-founder, Creandum

• Chris Best, Co-founder and CEO, Substack

• Mark Cuban, Investor and Entrepreneur (Shark Tank)

• Spencer Skates, CEO and Co-founder, Amplitude

• John Santora, CEO, WeWork

• Robert Herjavec, Investor and Entrepreneur (Shark Tank)

• Anna Piñol, Partner, NFX

• Martin Mignot, Partner, Index Ventures

• Anish Acharya, Partner, Andreessen Horowitz (a16z)

• …

The strategy itself is simple to describe and hard to execute. Identify high-signal insights and resources, distribute them consistently and ahead of the curve and build long-term trust with a global audience of founders.

Do that for long enough and it compounds into a distribution advantage that becomes very difficult to replicate.

4. Backing Founders With Distribution

Capital is only part of what I bring. Over the past year I’ve worked with teams directly on distribution and growth, on product launches, visibility and early momentum, including with companies like Vanta, Synthesia, ElevenLabs and HappyRobot, where the channels amplified their reach and positioning at moments that mattered.

The outcomes are measurable. Millions of views generated across the channels, more inbound demand, stronger investor momentum, and in several cases faster revenue growth at an early stage.

That is the part most checks can’t replicate and it is exactly why distribution is becoming a core component of venture value creation rather than an optional layer sitting on top of it.

5. What Three Years Taught Me About the Real Moat

Three years in, the model works. Writing every day brought me closer to founders, and that proximity is what now gets me into rounds I’d otherwise never see.

The newsletters and the following aren’t marketing wrapped around a fund. They’re the reason founders pick up the phone.

The plan from here is simple: keep growing the audience, get to the best founders earlier and back more of them. Capital has become easy to find. The trust and attention behind these channels took three years to build, and that is the real moat.

If you’re a founder building something I should see, or an investor starting to treat distribution as your edge, this is the thesis I’m betting the next three years on.

Cheers,
Guillermo!
