A seed round is a startup's first substantial round of outside investment. It is raised to turn a working product into early traction and to reach signs of product-market fit, typically following pre-seed capital and preceding a Series A. It's the round where the company transitions from "we're building something" to "we're building something people want," and where the bar for the next round (Series A) gets established.
The 2025 benchmarks (Carta and PitchBook):
| Metric | 2025 typical range | Notes |
|---|---|---|
| Round size | $2.5M-$5M | Hot AI/deep-tech can be $6M-$10M |
| Post-money valuation | $20M-$30M (median ~$24M) | All-time high in 2025; up from ~$18M in 2024 |
| Pre-money valuation | $18M-$25M | Subject to pool refresh placement |

A Large Language Model (LLM) is an AI system trained on massive amounts of text to predict the next token in a sequence. The prediction capability scales into broader abilities (reasoning, code generation, analysis, conversation, translation, summarization) as models grow in size and training data. Modern frontier LLMs range from 70 billion to 1+ trillion parameters and are the technology underlying ChatGPT, Claude, Gemini, Llama, and other generative AI products that have transformed software since 2022. It's the specific type of foundation model that handles text.
What LLMs actually do (the mechanics):
Tokens, not words: LLMs break text into tokens (sub-word units). "Tokenization" of a sentence might produce 10-...
A quarterly business review (QBR) is the recurring strategic review at quarter-end covering OKR achievement, strategic initiative progress, trends, lessons learned, and next-quarter planning. Typically a full-day or multi-day session, it's the strategic equivalent of monthly business reviews (tactical financial) and weekly business reviews (tactical execution), and is distinct from "customer QBRs" (customer success meetings with key accounts) despite the shared acronym. It is the leadership rhythm that closes each quarter and opens the next.
The standard internal QBR structure (1-2 days):
Quarter review (half-day):
Sales-Led Growth (SLG) is the go-to-market motion in which a dedicated sales team drives customer acquisition through outbound prospecting, demos, consultative selling, and contract negotiation. Marketing supports the motion by generating awareness and pipeline rather than directly converting leads. It's the traditional B2B SaaS motion, dominant for higher-ACV products and complex sales cycles, and the counterpart to [Product-Led Growth] (where the product drives acquisition without sales intervention).
When SLG is the right motion:
Higher ACV ($30K+): the deal size justifies the cost of sales reps.
Complex products: requiring consultative selling, demos, technical evaluation, and customization.
Multi-stakeholder buyi...
User experience (UX) is the total quality of a user's interaction with a product across usability, accessibility, performance, content, design, and emotional response. It treats the product as the experience the user actually has rather than just the interface they see, covering information architecture, visual design, and microinteractions. The term was coined by Don Norman at Apple in 1993 to capture everything that shapes how a person perceives and interacts with a system, beyond just visual design.
The components of modern UX work cluster into roughly six areas: usability (can the user accomplish what they're trying to do, with what speed and what error rate), information architecture (how content and functionality are o...
An exit multiple is the valuation multiple at which a company is acquired or goes public, most commonly revenue, EBITDA, or ARR multiples. Common variants include revenue multiple, EBITDA multiple, ARR multiple for SaaS, or user-count multiple for consumer products. It is used to compare exits across deals, inform founder valuation expectations, and serve as a primary lens through which strategic acquirers and PE firms evaluate targets. It is the shortcut metric most M&A conversations actually run on, despite the existence of more sophisticated valuation methodologies.
The major multiples by business model: SaaS / subscription: typically valued on ARR multiple (annual recurring revenue), with public-market multiples ranging fr...
An initial public offering (IPO) is the process of selling shares of a private company to the public for the first time. Listed on NYSE, Nasdaq, or international equivalents, an IPO is traditionally the marquee exit path for venture-backed companies, with investment-bank underwriters pricing the offering, allocating shares to institutional buyers, and the company raising primary capital in the process. It is also one of the rarest exit outcomes statistically, despite getting the bulk of the press coverage.
The standard process runs roughly: file a confidential S-1 with the SEC, respond to SEC comments through 2 to 4 rounds, conduct a [Roadshow] where executives pitch institutional investors over 1 to 2 weeks, price the offering the nigh...
QSBS (Qualified Small Business Stock) is an IRS provision under Section 1202 that excludes up to $10M-$15M (or 10x basis) in capital gains from federal tax. The One Big Beautiful Bill Act (signed July 4, 2025) created a two-regime structure: stock issued on or before July 4, 2025 follows the pre-OBBBA rules ($10M or 10x cost basis cap, $50M gross-assets ceiling, 5-year hold for the full exclusion); stock issued after July 4, 2025 follows the OBBBA rules ($15M cap inflation-adjusted after 2026, $75M gross-assets ceiling, tiered holding with 50% exclusion at 3 years, 75% at 4 years, 100% at 5 years, maximum exclusion up to $750 million). The exclusion is available to founders, early employees, and early investors. It is one of the most v...
The people side of building a company. This cluster covers founder roles and dynamics, the executive lineup, the hiring sequence, sales and customer success roles, compensation and equity, performance management, layoffs and severance, and the culture and operations that determine whether the team holds together. 63 entries.
If your business succeeds or fails on hiring (most do), this is the cluster you live in.
Everything about raising capital, from the first SAFE to the IPO. This cluster covers every named stage (pre-seed through Series E+), the investor types (VC, CVC, angels, family offices, crossover funds, strategic vs financial), the fund mechanics that drive investor behavior (LPs, GPs, fund life, carried interest), the crowdfunding regulations and platforms, the round structures (up, down, flat, bridge, extension), and the closing mechanics that make deals real. 97 entries.
This is the most thoroughly covered cluster in the lexicon because fundraising decisions compound for years.
