A buyer persona is a research-based, semi-fictional profile of an individual decision-maker inside the target customer. It captures role, goals, pain points, success criteria, information sources, objections, and typical buying behavior, used to shape messaging, content, sales scripts, and product decisions around how that specific role actually buys. It differs from ICP in scope: ICP describes the account or household; the persona describes the human inside it.
A useful persona is built from real customer research, typically a combination of 10 to 20 structured interviews with closed-won customers (the actual buyers), churned customers (the buyers whose problem you didn't solve), and lost prospects (the buyers who chose a com...
Fund life is the total contractual duration of a VC fund, typically structured as 10 years with two 1-year extension options. The "10+2" structure is divided into an investment period (typically first 5 years when new investments are made) and a harvest/exit period (years 5-10 when portfolio matures and exits). Fund life is a critical structural constraint that affects everything from when GPs can make new investments to when LPs expect distributions to how aggressively portfolio companies must pursue exits. It shapes the temporal dimension of how funds operate.
The standard structure:
Years 1-5: Investment period:
Training data is the corpus of examples (text, images, code, audio, video) used to train AI models. The quality and scale of training data are two of the three key inputs (alongside model size and compute) that determine final model capability per the empirical scaling laws. High-quality training data is increasingly the constrained resource in AI development as compute scales faster than data quality. It's the input that becomes the output: what the model can do is bounded by what it learned from.
The components of modern AI training data:
Pre-training data (foundation model training):
Quick pointer: this entry focuses on the tax-advantaged characteristics of founder-issued common stock (QSBS, 83(b), capital-gains holding-period math). For the structural setup at formation (RSPA, vesting, repurchase rights, the share split), see [Founders Stock].
Founder shares are the formation-stage common stock whose tax-advantaged characteristics convert a tiny dollar investment into a potentially massive tax-advantaged outcome. Those characteristics are Qualified Small Business Stock (QSBS) eligibility under §1202 (up to $10M-$15M or 10x basis excluded from federal capital gains per founder, with post-OBBBA stock issued after July 4, 2025 getting the $15M cap, a $75M gross-assets ceiling, and tiered holding periods),...
A stock option is the contract granting the right to purchase common stock at a fixed strike price for a defined period. It is used as the primary equity-compensation mechanic at venture-backed startups, vesting over time (typically 4 years with a 1-year cliff) before becoming exercisable. It is the standard structure for employee equity in C-corp startups, distinct from outright stock grants because the employee must pay to convert the option into actual shares.

IP assignment is the contractual transfer of intellectual property ownership from individuals (founders, employees, contractors) to the company. It is typically executed through Proprietary Information and Inventions Agreements (PIIAs) signed by employees and Confidential Information and Invention Assignment Agreements (CIIAAs) signed by contractors, ensuring that all IP created during employment or in connection with services belongs to the company rather than the individual creator. IP assignment is foundational for company ownership of its product, technology, and competitive advantages, and missing IP assignments are one of the most-common cap-table cleanup issues discovered during diligence. It is one of the most-importan...
Pitch iteration is the systematic refinement of the pitch deck and narrative based on investor feedback patterns collected across meetings. It's used to sharpen the pitch toward what consistently resonates while addressing recurring concerns, with the discipline being to iterate based on patterns (3+ investors raising the same concern) rather than individual feedback, to avoid creating Frankenstein decks that try to address every investor's specific objections while losing coherence. It is the discipline that transforms okay pitches into great ones through structured refinement.
The iteration process:
Capture investor feedback systematically:
Venture debt is a type of loan extended to venture-backed startups by specialized lenders. Lenders are banks and non-bank lenders focused on the venture market, with loans typically structured as 24-48 month term loans with monthly principal and interest payments and warrants attached giving the lender a small equity upside (typically 0.5-2% of the loan amount as warrant coverage). It is used as runway extension between equity rounds or as supplemental capital to a recent equity raise without the dilution of additional equity financing. It is the most-misunderstood form of startup capital, with founders consistently underestimating both its utility (when it works) and its risks (when it doesn't).
The structural mechanics: typic...
A tender offer is a structured offer to buy shares from a defined group of shareholders at a specified price within a defined window. It is used in two distinct contexts: acquiring control of a public company (the acquirer offers to buy shares directly from public shareholders, friendly or hostile), and providing secondary liquidity to employees and early investors in a private company (the company organizes a one-time or recurring purchase of shares from a defined group, typically alongside or between primary financings). The two use cases are structurally distinct but share the basic mechanic of a defined offer to a defined group at a defined price.
The public-company tender offer: an acquirer (often a strategic buyer or acti...
Early exercise is the action of exercising stock options before they have vested. The holder pays the strike price on unvested options and receives restricted stock subject to the company's right to repurchase the unvested shares at strike if the holder departs. It is a tax-planning move that starts the long-term capital-gains and QSBS holding clocks earlier, paired with an 83(b) election filed within 30 days of exercise. It is a powerful structural move when used correctly and a cash-binding mistake when used without understanding the implications.
