Information Density: Andreessen Horowitz – Signal Evidence & AI Readability

Information Density — The Lens

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Info Density Power-words vs. Substance ratio.

Information density is exceptionally high due to the Portfolio page, which lists specific, verifiable entities such as Airbnb (ABNB), Lyft (LYFT), and Coinbase (COIN). Headings like ‘Investing in Exa’ and ‘Need Series C? Call a16z’ provide direct, actionable nouns and stages rather than generic power words. The body substance ratio is bolstered by technical descriptors of their ‘two-team’ model (builders vs. operators) on the Team page. Minimal fluff is found, primarily restricted to high-level thematic H1s like ‘The Power of Our Network’.

Information Density is read straight from the body copy: how much of the text carries grounded, checkable substance versus hollow filler. Below is the clean text the engine analyzed, then the industry’s known generic-claim patterns to weigh it against.

[H1] The Power of Our Network

In 2009, Marc and Ben saw what other VCs didn’t: that the venture firms could give founders much more than cash and advice. We built our firm differently, with two teams working for you: First, investors who’ve built before: ex-founders and engineers, organized by vertical, who’ve already solved the problems you’re about to face. Second, operators who clear the path: marketing, policy, talent, and finance experts dedicated to solving the specific challenges of every stage. a16z pioneered this model, and we’re still the only firm with the scale to deliver on it.

Proof Expectations: FCA registration number with link to register, specific qualifications (DipPFS, ACII, CFA, CFP), published fee schedule or charging structure, named team with verifiable regulatory record, FSCS protection status and limitations, complaints data and FOS referral information…
