With $1.9B AUM across three funds, 200+ direct investments, 54 exits, and 15 unicorns seeded or backed at Series A, M13 has built a reputation for pairing venture math with hands-on execution.
Portfolio investments include companies like Lyft, Pinterest, Ring, Bonobos, Matterport, Shake Shack, Solana, and emerging leaders like Rho, Prepared, OpenFX, Arena Club & Niural AI. The firm is ranked Top 20 globally in the HEC-Dow Jones Venture Capital Performance Ranking and was named one of TIME’s Top 100 US VCs for 2025.
M13 targets 30–35 core investments per fund, aims for ~20% ownership, & structures its portfolio around power-law outcomes, not incremental 3x bets. Over the last three years, companies behind M13-led rounds have raised ~$800M in follow-on capital, reached Series B ~30% faster, and at ~25% higher valuations than the median.

M13: Power Laws & Portfolio Geometry
Carter characterizes the current VC market as divided into “two sports”
Large multi-stage funds deploying vast pools of capital into a small number of potential generational winners
Early-stage firms seeking alpha through concentrated ownership & asymmetry
M13 typically writes 30 to 35 core checks per fund. Its ownership target has evolved from approximately 10% in earlier funds to roughly 20% today, reflecting a deliberate shift toward higher conviction positions.
The economics are calibrated accordingly.
At M13’s fund size, the firm does not require outlier trillion-dollar outcomes to generate fund-level returns. As Carter explains:
“When someone says to me, this could be a $20 billion company, I say statistically speaking, it’s very unlikely. It could be, but there is math to it. There is pattern recognition.”
“If you have a 10% chance at 100x, you gotta take that shot on goal.”
The implication is that venture capital remains governed by power-law distributions. Incremental outcomes are structurally insufficient.
Courtney reinforces the asymmetry:
“You can’t aim for 3x if you want a 3x portfolio. You’ll end up under that.”
In other words, targeting moderate outcomes in a high-variance asset class often produces suboptimal aggregate performance.
Operational Leverage and Measured Outcomes
Unlike many traditional venture firms, M13’s team composition is heavily operator-weighted. Of approximately 40 professionals, only one previously worked at a venture capital firm. The remainder come from operating backgrounds across brand, growth, data, and product.
This structure underpins the firm’s Propulsion model — an operating platform designed to work directly with portfolio companies on specific performance drivers.
The firm tracks burn multiple, compounding growth rates, and business-specific indicators. In applied AI companies, for example, daily query growth may serve as a core metric.
An internal review cited by Carter offers measurable outcomes:
“We are doing an internal review the other day, and our portfolio companies have raised about $800 million behind rounds we’ve led the last three years. They’re raising those Series Bs about 30% faster at about 25% higher valuations than the median Series B. That means our hands-on approach is working.”
Whether this outperformance persists across cycles remains to be seen. But the data suggest a measurable relationship between operational engagement and follow-on financing velocity.
The competitive landscape, however, is increasingly dense.
“There are five or 10 companies going after every idea right now. They’re all well pedigreed, they’re all well funded. We wake up every day and say, look, we just gotta out execute everyone.”
He frames incremental improvement as compounding leverage:
“If we can get 1% better every day, we can be 37 times better by the end of the year.”
AI: Competing with Incumbents vs. Investing in Ripples
M13 views artificial intelligence as a horizontal layer reshaping multiple sectors. Yet they express caution toward foundation-model investing at peak valuations.
Carter describes the competitive reality bluntly:
“Innovators are competing with innovators who are competing with the best companies on the planet.”
The presence of hyperscalers with deep pockets of capital, data, and distribution, severely challenge any potential for return distributions for early-stage entrants at the base model layer.
Instead, M13 emphasizes second- & third-order effects.
Carter draws a historical analogy to the 1920s automobile industry: while car manufacturers represented the core technological breakthrough, significant wealth accrued to infrastructure and adjacent sectors enabled by the car.
“The job of a venture capitalist is to understand the latest technological innovation & then have a prepared mind to find where the best opportunities are.”
In practice, this translates to investment in applied AI businesses, infrastructure layers, and blockchain-adjacent use cases such as stablecoins. The thesis is less about headline breakthroughs and more about derivative value layers.
Los Angeles Value Creation
Los Angeles has historically been viewed as secondary to Silicon Valley in technology density. Yet over the past cycle, LA-based companies have generated hundreds of billions of dollars in enterprise value.
The potential SpaceX IPO at over $1T illustrates the catalytic effect of large liquidity events.. and Carter was clear to make sure we don’t undervalue it.
“We’re early investors, so we hope $1.5T — come on, Molly. Don’t jinx us.” lol.
“Anytime you have a big IPO like that, it puts a lot of wealth in people’s pockets. It allows people to go figure out what they want to do next. And so I think it will be fantastic for the ecosystem.”
Historically, large public offerings recycle both capital and talent. Early employees become founders. Founders become investors. Wealth compounds locally.
M13 does not typically invest directly in capital-intensive aerospace sectors, but Carter notes:
“We tend to invest in the software layers of some of these industries, but no doubt about it, it will be a big event & I think we’ll have very positive ripples.”
If AI’s first wave clusters in San Francisco, LA’s intersection of aerospace, media, creators, and consumer platforms may position it uniquely for second-order value creation.
Disciplined Approach
Across themes from portfolio construction, AI strategy, culture, & geography, M13’s framing returns to one central principle: disciplined probability management in a high-variance system.
“A data point is just a data point until they coalesce” Then, that’s the signal.
In venture capital, where outcomes are lumpy and narratives are abundant, the differentiator may not be pure-optimism, but calibration.
“I think we're probably the rare VC that doesn't think — although we have 15 unicorns under our belt — that we just have some special superpowers and we invest in special people and then special things happen.”
Whether M13’s model continues to perform will depend on execution across cycles. But its thesis with concentrated ownership, asymmetry, operational engagement, and second-order AI exposure, reflects a deliberate response to an increasingly capital-saturated environment.
