A lockup period is the 90 to 180 day window after an IPO during which insiders are contractually barred from selling or transferring their shares. Also called an IPO lockup, the restriction binds founders, employees, pre-IPO investors, and certain other affiliated parties, including from hedging their shares. It is designed to prevent a post-IPO supply shock that would tank the newly-public stock and to give the market time to absorb the float available from the offering itself. It is one of the most important structural features of a traditional IPO and one of the things direct listings deliberately abandon.
The standard structure: the underwriters require all insiders to sign lockup agreements as a condition of the IPO, with...
Addressable market is the portion of a total market a company can realistically serve given product capabilities, geographic reach, target segments, channels, and regulatory constraints. Often synonymous with SAM (Serviceable Addressable Market) in the TAM/SAM/SOM framework, it's typically much smaller than total market (TAM) but more strategically meaningful because it represents customers the company can actually pursue today. It is the market-sizing concept that most directly informs go-to-market strategy and resource allocation, more useful than total TAM for actual operating decisions.
What constraints define addressable market:
Product constraints:
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.
Competitive analysis is the systematic study of competitors' positioning, products, pricing, customers, go-to-market motion, financials, and strategic moves. It covers direct competitors, indirect competitors, potential entrants, and substitutes, and is used to identify differentiation opportunities, anticipate competitive moves, inform pricing and positioning, and develop sales battlecards that help reps win competitive deals. The discipline is focusing on actionable insights rather than producing exhaustive documents nobody reads. It is one of the most-conducted strategic exercises and one of the most-often wasted.
The dimensions to analyze:
Positioning and messaging:
Generative AI is the category of AI systems that create new content (text, images, code, audio, video, 3D) rather than classifying or analyzing existing data. The November 2022 release of ChatGPT marked the cultural and commercial inflection point that transformed generative AI from research curiosity to mainstream technology used by hundreds of millions of people within months. It's the category of AI that produces output rather than just labels or predictions.
The pre-ChatGPT history (compressed):
2014: Generative Adversarial Networks (GANs) introduced. First major generative image breakthrough.
2017: Google's "Attention is All You Need" paper introduces the Transformer architecture (the foundation for modern LLMs).
2018: Op...
An AI moat is the defensible advantage an AI startup builds to prevent commoditization by competitors. Five real moats exist in the AI era: data flywheel, workflow integration, distribution, brand and trust, and network effects. Raw access to foundation models is NOT a moat because everyone has the same APIs, making moat-building one of the most strategically important questions for any AI founder. It's the answer to "why can't anyone else build this?"
The five real AI moats:
1. Data flywheel ([Data Flywheel]):
An AI startup is a company whose product depends on artificial intelligence or machine learning as a core differentiator. The category breaks into three distinct archetypes: foundation model labs (OpenAI, Anthropic, Google DeepMind, Meta AI training the largest models), AI infrastructure (Hugging Face, LangChain, Pinecone, Weights & Biases providing tooling), and AI application companies (Cursor, Perplexity, Harvey, Glean building products on top of foundation models). Each archetype has fundamentally different economics, capital requirements, and defensibility characteristics. Understanding which category your AI startup falls into is the first step in evaluating its moat.
The three categories:
Foundation model labs:
A business plan is the written document describing a company's business model, target market, competitive position, operating strategy, team, and financial projections. It's used to align stakeholders and guide execution. Modern startup business plans rarely take the form of the traditional 30 to 40 page document; they more often appear as a pitch deck, a one-page Lean Canvas, or a short narrative memo.
The traditional business plan, with its executive summary, market analysis, organizational structure, marketing plan, operations plan, and 3 to 5 year financial projections, originated in mid-twentieth-century corporate planning and remains the format banks and SBA loan officers expect. For startups, the format has shifted. Mos...
