Dilution is the reduction in ownership percentage that existing shareholders experience when a startup issues new shares. Learn how dilution works mathematically, typical dilution per round, and why it isn't always bad.

AI and machine learning are related but distinct concepts. AI is the broad field of creating intelligent systems, while ML is a specific subset focused on learning from data. Understand the key differences and how they shape AI investing.

Generative AI refers to artificial intelligence systems that can create new content — including text, images, video, code, and audio. Learn about foundation models, key companies, and how generative AI is transforming industries.

SaaS metrics like ARR, churn, NRR, and LTV are critical for AI startups to track and understand. Learn the key metrics that investors evaluate and how AI companies benchmark against them.

ARR (Annual Recurring Revenue) is the annualized value of a company's recurring subscription revenue. Learn how to calculate ARR, how it differs from MRR and total revenue, and what ARR multiples mean for AI company valuations.

AI startup valuations can seem mysterious, but they follow identifiable patterns. Learn the key valuation methods used by venture capitalists — revenue multiples, comparable analysis, stage-based heuristics, and why AI companies trade at 50-100x ARR.

A cap table (capitalization table) tracks who owns what in a startup — including shares, options, warrants, and SAFEs. Learn how cap tables work, how they change with each funding round, and why managing yours correctly is essential.

Venture debt and equity are two distinct ways to fund a startup, each with different costs, structures, and trade-offs. Learn when to use debt vs equity, how venture debt works, and what warrants and covenants mean for AI founders.

An AI startup is a company that builds artificial intelligence technology as a core part of its product or service. Learn the difference between AI-native and AI-enabled companies, the main categories of AI startups, and what investors look for in the space.

Due diligence is the comprehensive investigation investors conduct before making a funding decision. Learn how VCs evaluate AI startups with real examples.

SAFE (Simple Agreement for Future Equity) notes are the most common instrument for early-stage AI startup funding. Learn how they work.

Convertible notes are short-term debt that converts to equity during a future funding round. Compare with SAFE notes for AI startup fundraising.

Startup runway is how long a company can operate before running out of cash. Critical for AI startups with high compute costs.

Burn rate measures how fast a startup spends cash each month. AI companies have uniquely high burn rates due to GPU costs and talent competition.

A decacorn is a startup valued at $10 billion or more. OpenAI, Anthropic, and Databricks are leading AI decacorns reshaping the industry.

Angel investors are high-net-worth individuals who fund startups at the earliest stages, often before venture capital firms get involved.

Product-market fit means a startup has found strong demand for its product. It's the most critical milestone for AI startups seeking Series A funding.

A down round occurs when a startup raises funding at a lower valuation than its previous round. Learn the causes, consequences, and real examples.

Venture debt is non-dilutive financing for startups that supplements equity funding. AI companies use it to fund GPU clusters without giving up ownership.

An exit strategy is how founders and investors realize returns — through IPO, acquisition, or secondary sales. Learn the most common AI startup exits.

A pivot is a fundamental shift in a startup's business model, product, or target market. Many successful AI companies pivoted before finding success.

An IPO (Initial Public Offering) is when a private company first sells shares to the public on a stock exchange. Learn how AI companies like Palantir went public.
