GDPR (General Data Protection Regulation) is the EU's comprehensive privacy regulation enacted in 2018. It establishes data protection rights for EU residents and applies to any company processing their personal data regardless of where the company is based. Non-compliance risks fines up to 4% of global annual revenue (or €20M, whichever is greater) and other regulatory enforcement. Compliance requires documented data practices, user consent mechanisms, data subject rights handling (access, deletion, portability), data breach notification procedures (72-hour to supervisory authority), and other operational requirements. It's the regulation that fundamentally changed how companies globally handle personal data.
The key requir...
Growth hacking is the experimental discipline of using non-obvious, leverage-driven tactics to drive rapid user or revenue growth, coined by Sean Ellis in 2010. It combines marketing, product, engineering, and data, often by exploiting existing platforms, distribution loops, or product mechanics rather than by spending on traditional advertising. It is the experimental, scrappy ancestor of modern growth marketing, and the term has been so over-claimed that the original meaning is nearly buried.
The canonical historical examples define what growth hacking actually was. Hotmail appended "PS: I love you. Get your free email at Hotmail" to every outgoing message in 1996 and went from zero to 12 million users in 18 months. Airbnb ...
Restrictive covenants is the umbrella term for the package of post-employment restrictions in employment agreements and PIIAs. The package typically includes non-compete (where enforceable), non-solicitation (customers and employees), confidentiality, IP assignment, return of company property, non-disparagement, and sometimes additional provisions. Used together to protect the company's interests beyond the duration of the employment relationship, the specific package and its enforceability vary by jurisdiction, role, and consideration provided. Restrictive covenants is shorthand for "all the post-employment restrictions" in employment law.
The standard package:
Non-compete: restricts working for competitors for define...
Option modification is a change to outstanding stock options after the original grant date. Modifications include repricing, exchange programs, extending the exercise term or post-termination exercise window, and accelerating vesting, with significant consequences including potential ISO disqualification (modifications can be treated as new grants under Section 422), 409A penalty exposure, and incremental accounting expense. It is one of the most-mishandled areas of equity-comp administration and a common source of tax and accounting problems at companies that don't get specialized advice.
The main types of option modifications:
Repricing: lowering the strike price of outstanding options to current FMV. Used when the com...
An employment agreement is a comprehensive contract governing an employment relationship between company and employee, used primarily for executives and international employees. It covers compensation, equity, severance, restrictive covenants, indemnification, and other material terms in greater detail than the simpler offer letter used for most US employees at-will. The document covers role and responsibilities, base salary and equity grants, term and termination triggers, severance entitlements, restrictive covenants (non-compete, non-solicit, confidentiality, IP assignment), indemnification, and dispute resolution. Offer letter and employment agreement serve similar purposes but at different complexity levels.

GPU cost is the underlying compute cost of training and running AI models, dominated by Nvidia's H100, H200, B200, and B300 chips at $25,000-$50,000 each. GPU availability and cost are the limiting factor for AI training because foundation model labs need thousands of GPUs running together in clusters. The GPU supply chain is the single largest infrastructure story of the 2020s tech boom. Behind every AI capability is a stack of expensive GPUs running hot.
The Nvidia GPU lineup (mid-2026):
| GPU | Launch | Approximate price | Use case |
|---|---|---|---|
| A100 | 2020 | $10K-$15K | Legacy AI workloads |
| H100 | 2022 | $25K-$40K | Mainstream LLM training/inference |
| H200 | 2024 | $30K-$50K | Improved memory for large models |
| B100/B200 | 2024-2025 | $40K-$60K | Next-gen Blackwell... |
Startup equity is ownership in a startup, expressed as shares of stock or rights to shares such as options, warrants, and SAFEs. It is divided across three main groups over the company's lifetime: the founders, the employees, and the outside investors. It is the currency of a venture-backed company, used to align everyone who builds the business with the financial outcome of the business.
A typical venture-backed cap table separates equity by class and by holder. Founders are issued founder common stock at incorporation, usually subject to a four-year vesting schedule with a one-year cliff. Employees receive stock options drawn from an option pool that typically represents 10 to 20 percent of fully diluted shares at the first...
A liquidation event is the trigger defined in preferred stock terms that activates the liquidation preferences and waterfall mechanics. Typical triggers include sale of the company (acquisition or merger where existing stockholders own less than majority of surviving entity), sale of substantially all assets, dissolution or winding up of the company, and sometimes other defined events like change of control transactions. The specific definition matters because what counts as a "liquidation event" determines when preferred stockholders get paid and common stockholders only get what remains. It is the mechanism that activates preferred preferences; understanding what triggers it is foundational.
The standard liquidation even...
Marketing automation is the use of software platforms to execute, schedule, and measure marketing tasks across email, SMS, web, push, and ad channels. Tasks are based on customer behavior, attributes, and lifecycle stage, with the goal of delivering the right message at the right time to the right person without requiring manual effort per send. It is the engine layer beneath drip campaigns, lifecycle marketing, lead scoring, and most modern email and CRM workflows.
The platform landscape in 2025 segments by company stage and use case. B2B-leaning platforms with built-in CRM: HubSpot (the most common SMB-to-mid-market default), Marketo / Adobe Marketo Engage (enterprise), Salesforce Marketing Cloud and Pardot/Account En...
A Non-Disclosure Agreement (NDA) is a legally binding contract between parties to keep specified information confidential and not use it outside the agreement's scope. Also called a confidentiality agreement or CDA, it is used to protect trade secrets, business plans, customer data, source code, pricing information, and other sensitive information during business discussions, employment relationships, contractor engagements, partnership negotiations, and M&A processes. It is one of the most-common business contracts and one founders consistently misuse, both by asking for NDAs in inappropriate contexts and by failing to use them in appropriate ones.
The two main NDA types: one-way (or unilateral) NDA binds only one party to confide...
