- DPI
- Distributions to Paid-In capital — the ratio of cash actually returned to investors versus capital invested; the only 'real' VC performance metric because it measures actual cash, not paper gains.
- Top decile
- The top 10% of funds ranked by performance; a standard benchmark in venture capital used to distinguish elite funds from the broader market.
- Management fee
- An annual fee (typically 2% of fund size) charged by a VC fund manager regardless of performance; central to Maris's argument that large funds perversely incentivize GPs.
- GP
- General Partner — the fund manager at a VC firm who makes investment decisions and earns management fees and carried interest.
- LP
- Limited Partner — an outside investor (e.g. endowment, pension fund) who provides capital to a VC fund but has no role in managing it.
- RIA
- Registered Investment Adviser — a regulated firm that manages client assets; Maris used the term to distinguish asset-gathering at scale from hands-on venture investing.
- In silico
- Performed by computer simulation rather than in a lab; Maris used it to describe simulating a human cell computationally to accelerate drug discovery.
- TAM
- Total Addressable Market — the full revenue opportunity available if a product achieved 100% market share; Maris called human biology 'probably the largest TAM in the world.'
- H-1B
- A US visa category for skilled foreign workers in specialty occupations; Maris cited H-1B restrictions as a driver of scientific brain drain from the US.
- Physics engine
- Software that simulates physical laws (motion, collision, gravity) in digital environments; Maris used it as a metaphor for the infrastructure layer that will make sophisticated AI possible.
- Ambient computing
- A computing environment where technology is embedded invisibly into everyday surroundings rather than requiring explicit interaction; Maris cited it as AI's end state.
- Backtesting
- Testing an investment strategy against historical data to evaluate how it would have performed; Maris described running millions of backtests to design Google Ventures' portfolio.
- Zork
- A landmark 1977 text-adventure game requiring exact text commands; Maris used it to illustrate the brittleness of today's AI, which he likened to Zork's turn-response interaction model.
- Bimodal
- Having two distinct peaks in a distribution; used here to describe venture returns where a handful of funds generate enormous gains and the majority lose money.
- Super critical
- Borrowed from nuclear physics, describes a self-sustaining chain reaction; Maris used it to describe the runaway competitive pressure on OpenAI and Anthropic if Google slashes token prices.
- Discontinuous return compression
- A sharp, non-linear drop-off in returns that occurs above a specific fund-size threshold, rather than a gradual decline; Maris cited this occurring above $750M in fund size.
- Calico
- A longevity-focused biotech company co-founded by Bill Maris and incubated within Google; focused on understanding the biology of aging.
- Sand Hill Road
- The street in Menlo Park, California synonymous with Silicon Valley's venture capital industry, home to many of the world's most prominent VC firms.
