North Star Framework vs North Star Metric: the framework is the full operating system, the NSM plus input metrics, business outcomes, team rituals, and decision rules. The [North Star Metric] is just the single number at the center of it. If you're picking the metric, read NSM; if you're installing the operating system around it, you're in the right place.
The North Star Framework is the strategic alignment system developed by Amplitude that connects a North Star Metric to input metrics and business outcomes. The North Star Metric is the one metric most-correlated with long-term business success and customer value; input metrics are levers teams can move to improve it; business outcomes are the financial results the N...
A weekly business review (WBR) is the recurring leadership-team meeting that reviews execution metrics, surfaces issues, makes tactical decisions, and aligns leadership. Typically 60-90 minutes, it's one of the operational rhythms that distinguishes well-run companies and the meeting where most weekly tactical decisions happen. It is the leadership team's primary operational rhythm.
The standard WBR structure (60-90 minute meeting):
Metrics review (20-30 minutes):
Issue surfacing (15-20 minutes):
Defensibility is the ability of a business to sustain competitive advantage over time. It encompasses moat categories (network effects, scale, brand, switching costs, regulatory, IP) plus operational excellence, execution velocity that compounds small advantages faster than they can be copied, and continued investment in the mechanisms that produce defensibility. The discipline is more dynamic than "moats" suggests because most advantages erode over time without continued effort. It is the operational sister of moats: moats are the structures; defensibility is the practice of maintaining and strengthening them.
The defensibility framework:
Structural defensibility (moats):
An executive summary is a 1 to 3 page prose document summarizing a startup's business, market, financials, team, and capital ask for investors. It covers business model, traction, market opportunity, and the capital ask, more substantive than a one-pager and more concise than a full business plan. It's used as a companion artifact to a pitch deck for investors who prefer prose, as a leave-behind that captures more nuance than slides allow, and as a primary artifact in some institutional-investor processes (especially family offices, growth-equity firms, and corporate-venture groups). It is the format that bridges the visual-heavy pitch deck and the written depth of a business plan.
The structure of a typical investor execu...
Accessibility (a11y) is the practice of designing products usable by people with disabilities, governed by WCAG 2.x and legally required under the ADA and EAA. The 11 in a11y stands for the 11 letters between the "a" and the "y". The disability scope spans visual impairments (low vision, blindness, color blindness), auditory impairments (deaf, hard of hearing), motor impairments (limited mobility, tremors), and cognitive impairments (dyslexia, ADHD, autism). The European Accessibility Act became enforceable June 2025. It is one of the most-under-invested-in product disciplines despite affecting a meaningful share of every product's user base.
The WCAG 2.x standard (current version 2.2, published October 2023) organizes accessi...
The foundational vocabulary every founder needs before everything else. This cluster covers what a startup actually is, the categories that distinguish them (bootstrap vs venture-backed, lifestyle vs scale-up), the support ecosystem (accelerators, incubators, agencies), the early credits and grants founders chase, and the structural concepts (founder-market fit, why startups fail) that shape every decision that follows. 21 entries.
If you're new to startup vocabulary, start here. If you're a few years in, this cluster is the conceptual baseline against which everything else is read.
Product differentiation is the set of attributes that make a product meaningfully distinct from competitors, allowing the company to compete on something other than price. It is one of the foundational concepts of competitive strategy, formalized in Michael Porter's 1980 book "Competitive Strategy," which named differentiation as one of three generic competitive strategies (alongside cost leadership and focus).
Differentiation typically falls into three categories. Vertical differentiation is objective quality: most customers would agree this product is better on a measurable dimension (faster, more reliable, more accurate). Horizontal differentiation is preference: customers reasonably disagree about which is better...
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...
An equity grant policy is the documented framework for granting equity to employees. It covers grant size by role and level, refresh grants, acceleration provisions, vesting schedule, and consistent application across hires, providing both fairness (similar roles get similar grants) and predictability (managers know what to offer) that case-by-case grant decisions lack. It is the operational discipline that distinguishes companies that grant equity systematically from companies that negotiate every grant individually.
The components:
Grant size by role and level:
Agile is an iterative software development philosophy formalized in the 2001 Agile Manifesto, emphasizing working software, customer collaboration, and responsiveness to change. It rejects rigid up-front planning, contract negotiation, and process compliance, implemented through frameworks like Scrum, Kanban, Extreme Programming (XP), and at large-organization scale, SAFe and LeSS. It is the dominant operating philosophy of modern software product teams and the most-misunderstood word in the discipline.
The Agile Manifesto, written in February 2001 by 17 software practitioners at a ski lodge in Snowbird, Utah, states four values: individuals and interactions over processes and tools; working software over comprehensive documentation; ...
