Activation is the funnel stage where a new user reaches first meaningful value from a product, the moment commonly called the aha moment. It is measured as the percentage of signups who complete a defined activation event within a specified time window (for example, "imported a first contact within 24 hours of signup," "sent a first message within 7 days," "invited a teammate within 14 days"). It is the stage in the AARRR funnel between acquisition and retention, and the single most-underinvested stage in most early-stage startups.
The classic framework for defining activation is the "aha moment formula" popularized at Facebook: identify the small set of in-product actions that, when completed early, predict long-term retention, ...
Vesting acceleration is the contractual mechanic that vests some or all of an equity holder's unvested shares upon defined trigger events. It applies to stock options, restricted stock, founders stock, and RSUs, with two primary structures: single-trigger (acceleration on a change of control alone) and double-trigger (acceleration only if the holder is also terminated without cause or resigns for good reason within a defined window). It is a critical equity-grant term that determines how much of an executive's or employee's equity actually pays out in an exit scenario.
The two main structural flavors:
An option pool refresh is the increase in shares available in the option pool, typically negotiated as part of a priced funding round. The critical structural question is whether the new pool shares are added pre-money (diluting existing stockholders, particularly founders) or post-money (diluting all stockholders proportionally including new investors). It is one of the most economically significant negotiation points in any priced round, and the founder dilution impact of pre-money pool refresh is often larger than the dilution from the investment itself.
The pre-money vs post-money option pool math:
A Marketing Qualified Lead (MQL) is a lead that has met defined marketing criteria indicating readiness for sales follow-up. Qualification typically combines demographic fit (job title, company size, industry matching ICP), behavioral signals (downloaded gated content, attended webinar, requested demo), and engagement scoring (lead score above threshold). The MQL designation triggers handoff from marketing to the sales team (typically the SDR or BDR team) for outreach and qualification. It's the bridge between marketing-generated awareness and sales-driven pipeline.
The MQL → SQL → Opportunity progression:
Cost per click (CPC) is the amount an advertiser pays each time a user clicks an ad, set in real time through an auction. The auction runs on the major ad platforms (Google Ads, Meta, Microsoft Ads, LinkedIn, TikTok, Amazon) and varies widely by industry, keyword, audience targeting, ad quality, and competitive intensity. It is the unit price of paid traffic and the most-watched number on a paid-acquisition team's daily dashboard. It is also one of the easiest metrics to over-optimize.
CPCs are set by auction, not by list price. On Google Ads, the auction takes the advertiser's max bid and multiplies it by Quality Score (a 1 to 10 measure based on expected click-through rate, ad relevance, and landing-page experience) to dete...
Treasury stock is shares the company has issued and subsequently repurchased that the company itself now holds in a corporate treasury account. The shares are neither outstanding (held by parties other than the company) nor canceled (retired from the issued count), carrying no voting rights, no dividend rights, and not included in EPS or per-share metric denominators, with the company able to either reissue or formally retire them by board action. It is the structural category for shares the company has bought back but not yet canceled or reissued.
The mechanic of treasury stock:
The product lifecycle is the four-stage model of commercial life through introduction, growth, maturity, and decline, used to inform investment, pricing, and sunset decisions. Introduction covers launch and early adoption; growth covers rapid adoption, scale, and competitive entry; maturity covers slowing growth and pricing pressure; decline covers replacement by alternatives and eventual sunset. The framework was popularized by Theodore Levitt in his 1965 Harvard Business Review article "Exploit the Product Life Cycle" and has been adapted from physical-product marketing into software product management.
The four classical stages with their typical characteristics: introduction (low sales volume, high per-unit cost, focus...
A fund of one is a venture fund structure with a single limited partner (LP). Sometimes called a "managed account" or "separately managed account/SMA," it is used by family offices, large institutional investors, sovereign wealth funds, or other large allocators who want dedicated capital deployment, customized investment terms (specific sector focus, geographic constraints, ESG requirements), and direct ownership economics without sharing fund returns with other LPs. The structure is distinct from traditional multi-LP funds and provides both more customization and more direct control to the single LP at the cost of the GP losing fundraising leverage and LP diversification. It's the fund structure for "one large LP wants their o...
A unicorn is a privately-held venture-backed company valued at $1 billion or more. The term was coined by venture capitalist Aileen Lee in a 2013 TechCrunch article describing the rarity of such outcomes at the time (only 39 unicorns existed globally then), and has since become an ordinary category as the venture industry has matured. CB Insights and Crunchbase track the global unicorn population at approximately 1,200+ companies as of 2026, making it a meaningful but no longer unusual milestone, the most-recognized valuation marker in the venture industry and a useful benchmark for understanding where a company sits relative to peer outcomes.
The history and current state of unicorns:
A venture capital fund is a limited partnership (occasionally an LLC) typically structured with a 10-year life that holds capital commitments from Limited Partners (LPs). It deploys investments into startups during its first 4-5 years (the "investment period"), manages and supports portfolio companies during the back half (the "harvest period"), and distributes proceeds to LPs as portfolio companies exit through acquisitions, IPOs, or secondary sales. It is the structural unit of the venture capital industry, and every VC firm's competitive dynamics, decision-making, and timing pressure flow from the constraints of the fund lifecycle.
The standard fund lifecycle:
