Alex Emerman, partner at Andreessen Horowitz's growth fund, manages a portfolio of breakthrough companies including Waymo, Kalshi, Robinhood, Stripe, Revolut, and 11 Labs. His team focuses on backing market leaders with exceptional growth rates, typically requiring several hundred percent growth for early-stage investments.

The conversation explores the massive disconnect between public and private market growth rates, with fewer than five public companies growing above 30% while A16Z's portfolio averages over 100% growth. Emerman discusses how AI companies are reshaping traditional metrics like gross margins, and why engagement has become the critical leading indicator for retention in fast-growing AI businesses.

Key portfolio developments include Waymo's $16 billion Series D at $126 billion valuation, 11 Labs' $500 million round, and Kalshi's emergence as the leading regulated prediction market. The discussion covers A16Z's investment philosophy, drawn from insights in The Hard Thing About Hard Things and their own Executive Hiring Guide, emphasizing the importance of backing market leaders who can achieve the new $10 billion top 1% outcome threshold.

The Great Divide: Private vs Public Market Growth Rates

"There are fewer than five companies growing north of 30% this year" in public markets, while A16Z's growth portfolio averages over 100% growth, creating a massive disconnect between public and private market performance.

"OpenAI and Anthropic alone added as much revenue last year as half of the public cloud universe excluding the Mag 7," demonstrating how AI companies are concentrating growth in private markets.

The most common question now is "do gross margins matter?" as AI companies show 0-50% margins versus traditional software's 70% margins, but margins still matter if there's a believable path to improvement.

Engagement has become the critical metric as a leading indicator of retention, especially important since many AI companies have annual contracts and their revenue base hasn't come up for renewal yet.

Waymo's Autonomous Vehicle Dominance Strategy

Waymo raised $16 billion at $126 billion valuation in their Series D, with A16Z participating in all four external rounds since the Series A.

"In San Francisco, it got to 25% market share really quickly with very few cars, surpassing Lyft" without full Bay Area coverage, highway access, or airports until recently.

Growth is constrained by car deployment rather than demand - "if they put more cars on the road in San Francisco that market share would be much closer to Uber."

The ride-hailing market represents less than 1% of vehicle miles in the US, suggesting massive expansion potential as autonomous vehicles enable new use cases and lower prices.

Waymo's lidar-based approach provides more data and better performance in adverse weather compared to Tesla's camera-only FSD system, with "significantly ahead" safety metrics in Austin comparisons.

11 Labs: The Rare Consumer-Enterprise AI Success

11 Labs raised $500 million with enterprise customers including Meta, Salesforce, Deutsche Telecom, and Revolut building agents on their platform.

"It's very rare to have like a great consumer business and a great enterprise business" - 11 Labs maintains both a thriving organic consumer base and growing enterprise revenue.

CEO Mati Staniszewski is "an exceptionally fast executor" who has shipped more models across breadth while building defensibility beyond just having the leading voice model.

Use cases span sales, customer support, interviewing, healthcare, consumer applications, and financial services, demonstrating audio as a platform rather than just a feature.

Kalshi's Regulatory-First Prediction Market Victory

Kalshi became "number one across users, revenue, volume, any metric that anyone would care about" after being number two when A16Z invested.

Founders Tarek and Luana "were getting punched in the face for four years and told no" while pursuing CFTC regulatory approval, taking the more responsible path.

The regulatory-first approach enabled partnerships with Robinhood, Coinbase, CNN, and CNBC - "real mature organizations that are entrusting Kalshi."

Unlike sportsbooks that profit when users lose, "Kalshi matches you with other market participants and they have a take whether you win or you lose," avoiding traditional gambling misalignment.

Fintech Convergence and Differentiation Strategies

Robinhood has "11 lines of business that are doing 100 million or more in revenue," demonstrating incredible diversification beyond core investing.

Revolut operates as "the true fintech super app" where "you can save, send, spend, borrow, invest" with 10 different revenue streams, none exceeding 20% of total revenue.

Revolut's transactional focus versus lending-heavy neobanks results in "40% ROEs which are higher than a neobank" with enterprise-like retention over 100%.

Brian Armstrong of Coinbase "should get more credit for reminding the world that companies should be mission focused," particularly during his bold September 2020 stance on company culture.

A16Z's Market Leadership Philosophy and Scale

A16Z raised "18% of all US venture dollars last year" reflecting their belief that top 1% outcomes have grown from under $1.5 billion to $10 billion, doubling every five years.

"We are snobs around growth" - requiring several hundred percent growth for early-stage companies and maintaining portfolio average over 100% growth rates.

The firm's philosophy draws from The Hard Thing About Hard Things, which remains "the most common that our founders refer to" for entrepreneurial challenges and leadership guidance.

Their Executive Hiring Guide provides tactical processes for specific roles, with founders referencing it "whenever they have a search" for executive positions.

"First place gets a Cadillac, second place gets steak knives, third place you're fired" - emphasizing the critical importance of backing market leaders who accumulate most market cap.
