A performance review is a periodic structured assessment of an employee's performance against expectations, conducted by their manager. Also called performance evaluation, performance appraisal, or annual review. Some companies add input from peers and direct reports via 360-degree review. Used for compensation decisions (raises, bonuses, equity refresh), promotion discussions (level changes, expanded scope), and developmental feedback. Most performance reviews are too infrequent (annual cycles miss most of the year's performance) and too vague (ratings like "meets expectations" don't drive behavior change) to actually accomplish their stated purpose. It is one of the most-implemented and least-effective HR disciplines at...
A foundation model is a large-scale AI model trained on broad, diverse data and designed to be adapted to many downstream tasks. Adaptation happens via fine-tuning, prompting, or API access. The term was coined by Stanford's Center for Research on Foundation Models in 2021 and now describes GPT-4, Claude, Gemini, Llama, Mistral, and similar models that form the base layer of the modern AI stack. The foundation model is to AI applications what AWS is to web applications: shared infrastructure that powers everything built on top.
What distinguishes foundation models:
Scale: hundreds of billions to trillions of parameters. Trained on hundreds of billions to trillions of tokens of data.
General-purpose training: trained on broa...
Round size is the total capital raised in a financing, determined by balancing runway, milestones, dilution, and capital efficiency. Key factors include runway needs (typically 18-24 months of operating cash), capital required to hit milestones for the next round, dilution tolerance (more capital means more dilution at given valuation), valuation impact (very large rounds at high valuations create future pressure), and capital efficiency (raising more than needed creates "fat" operations). Right-sizing is one of the most-important fundraising decisions and one founders frequently get wrong by raising too much (excess dilution, future pressure) or too little (insufficient runway, premature next-round fundraise). It's the dial that...
The traction slide is the pitch-deck slide showing real numbers that prove the business is working, scrutinized hardest after the team slide. The numbers include revenue, revenue growth rate, customer count, customer growth rate, retention, key milestones hit, and notable customer logos if applicable, typically delivered immediately after the solution slide and designed to demonstrate that the founders' thesis isn't just plausible but is starting to play out in measurable customer behavior. It is the artifact through which underlying [Traction] gets presented, and the slide where the gap between "looks good in a chart" and "actually means something" gets the most scrutiny.
The metrics that matter, by stage and business model:...
A bootstrap startup is a company built without outside equity investment, funded by founder savings, early revenue, and reinvested profit. Also called a bootstrapped startup, the term comes from the phrase "pull yourself up by your bootstraps" and refers to the financial self-reliance of the model, which allows the founders to retain full ownership and control of the business.
Bootstrapped companies trade slower growth for full ownership and decision authority, and the path often leads to a [Lifestyle Business] rather than a venture-scale exit. The founders own 100 percent of the equity (no dilution from investors), set their own pace, and pick their own customers and timelines, but they also fund every dollar of growth fr...
A traction startup is one that has produced measurable, quantitative evidence that its product is being adopted, used, and valued by customers. The evidence shows up in metrics like revenue growth, paying users, retention, engagement, or specific conversion behaviors that prove the market wants what the company is offering. Traction is the precursor to product-market fit (PMF): the early signal, where PMF is the durable state when that signal becomes sustainable, accelerating demand.
Real traction is distinguished from vanity metrics by one test: does the number get bigger as the company stops pushing on it, or only when the company pushes? In a pitch deck, the underlying traction shows up as the [Traction Slide]. Press mentions, a...
Contribution margin is revenue minus all variable costs (COGS plus variable sales and marketing plus variable customer-success), expressed as a percentage of revenue. It provides a view of unit profitability that accounts for the full cost of serving each customer rather than just delivery costs (gross margin). The metric is particularly useful at marketplace and consumer companies where variable costs go well beyond COGS, and less commonly used at SaaS companies where most non-COGS costs are fixed at scale. Contribution margin is the deeper unit-economics view that gross margin alone can miss.
The calculation:
Basic formula:
Affiliate marketing is the pay-for-performance acquisition channel where third parties earn commission for driving qualifying actions, typically sales or signups. Affiliates promote the product through their channels (websites, content, social media, email lists) and receive a percentage of revenue or fixed fee per conversion generated, tracked through unique referral links or codes. It's the original performance-based marketing channel, predating digital advertising, and remains a significant acquisition source for many B2C and some B2B businesses.
How affiliate marketing works:
Network effects exist when a product becomes more valuable to each user as more users join, creating a self-reinforcing dynamic where leaving becomes increasingly costly. They are the strongest category of moat available to a startup because they compound rather than depreciate. They explain why a handful of platforms (Facebook, Uber, eBay, LinkedIn, Visa, Microsoft Excel) dominate their categories despite having no patent or proprietary technology that competitors could not replicate.
The major types: direct network effects (one-sided, also called same-side) where each user benefits directly from more users of the same kind, as in phones, fax machines, WhatsApp, or Zoom; two-sided or multi-sided network effects where multip...
A story arc is the narrative structure underneath a winning pitch, used to make a pitch emotionally resonant and memorable rather than just informational. It typically follows a hero's-journey-style progression (the current state of the world, the inciting problem that disrupts it, the insight or capability that becomes available, the solution that emerges, the early evidence it's working, and the bigger world this leads to), and is dramatically more effective than a feature-list walkthrough would be. It is the deeper layer of pitching that distinguishes founders who can fundraise from founders who can't, and the layer most under-taught in standard pitch-deck advice.
The classical narrative template applied to pitching: stasis ("h...
