An offer letter is the written employment offer extended by a company to a candidate, documenting the terms of the employment relationship. The document covers role and title, base compensation, equity grant (typically subject to subsequent board approval and stock option agreement), variable compensation if applicable, benefits eligibility, start date, at-will employment status (in most US states), reporting structure, and any role-specific terms (relocation assistance, signing bonus, special vesting). It is the closing document of the hiring process that the candidate signs to accept the role, and establishes the contractual basis for the employment relationship going forward. It is the legal anchor of every new employment re...
Regulation CF (Regulation Crowdfunding) is the SEC framework that allows startups to raise up to $5 million annually from non-accredited investors via approved funding portals. Effective May 2016 under authority of the 2012 JOBS Act, it requires offerings to run through online platforms registered with the SEC and FINRA, with per-investor contribution limits, mandatory disclosure requirements, and platform-mediated investor flow. It is the regulatory mechanism behind US equity crowdfunding and the first time non-accredited individual investors could legally invest in private startups at small dollar amounts.
The key parameters:
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...
A hiring plan is a structured roadmap of roles to fill over a defined period (typically 12-18 months), with role-by-role timing, costs, and dependencies. For each role, the plan documents the expected start date, function/department, level (IC, manager, senior leader), total compensation (cash plus equity), and dependencies (e.g., "this role starts after we close Series A" or "this role depends on hitting $5M ARR"). The plan is used both for internal execution (recruiting team works against it) and external capital planning (the option pool refresh and financing-round size are calibrated against it). It is one of the most-used and least-formalized operational tools at startups, and the document that determines both who joins the...
Content marketing is the practice of creating and distributing valuable, relevant content to attract, engage, and retain a clearly defined audience. Formats include articles, videos, podcasts, guides, tools, templates, and newsletters, with the goal of driving profitable customer action. The term was popularized by Joe Pulizzi at the Content Marketing Institute in the late 2000s; the underlying practice (publishing useful media to earn trust before asking for a sale) has existed since John Deere launched The Furrow magazine in 1895.
Content marketing is the slowest-paying and longest-compounding channel after SEO, with which it overlaps heavily. The economics work because a strong piece of evergreen content keeps generatin...
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:
Regulation A is the SEC framework allowing companies to make public-like securities offerings up to $75 million annually with less burden than a full IPO. Often called Reg A+ following the 2015 expansion under the JOBS Act, it is structured in two tiers (Tier 1 up to $20M with state-level coordination, Tier 2 up to $75M with federal preemption of state law). It is sometimes called a "mini-IPO" because shares can be freely traded post-offering and the company can market the offering publicly. It is the regulatory layer between Reg CF crowdfunding (smaller, less complex) and full IPO (larger, much more complex), occupying a middle space that few companies actually use but that fits specific situations well.
The two tiers:
A one-pager is a single-page document summarizing a startup's business, market, traction, team, and capital ask for investors. It's used as a cold-outreach attachment when a full pitch deck would be too heavy, as a leave-behind after meetings to keep the conversation alive, or as an alternative artifact for some investor styles (especially angels or family offices) who prefer concise prose over slides. It is one of the most-undervalued fundraising artifacts because founders pour effort into the deck and treat the one-pager as an afterthought, missing that the one-pager is what actually gets forwarded inside investor firms.
The structure that consistently works: headline + tagline (one sentence describing what the company does, who...
Pitch practice is the systematic rehearsal of investor pitches with structured feedback to refine the pitch before real investor meetings. It builds founder confidence, surfaces questions and weaknesses, and iterates toward a sharp, tight pitch that lands well with target investors, with practice partners ranging from advisors and other founders (most valuable) to colleagues and even mirror practice for solo founders. It is the discipline that distinguishes founders who land funding from founders who pitch poorly.
The structure:
Solo practice:
Practice with advisors / other founders:
A business license is a government-issued permission to operate a specific type of business in a specific jurisdiction. Licenses are often required at multiple levels (federal, state, county, city) and vary widely by industry, ranging from broad general business licenses required by most cities to specialized professional licenses for regulated activities like healthcare, food service, transportation, and financial services. Penalties for operating without required licenses include fines, business closure, and personal liability. It is the area of startup compliance most consistently neglected by founders who assume "I formed an LLC, I'm good," and one of the most common surprises during fundraising or M&A diligence.
