What this toolkit is for, and who should use it

Building a venture-backed company is a sequence of legal decisions, made under time pressure, that are expensive to unwind later. The wrong entity, an unvested co-founder who walks with half the company, IP that lives in a founder's personal GitHub, or a "handshake" investment that quietly violated securities law—each is a landmine that can blow up a future financing or acquisition. This toolkit maps the whole path from formation through early fundraising so founders and their counsel can make those decisions deliberately and in the right order.

It is written for founders who want to understand why the standard playbook is standard, for early-stage operators papering their first deals, and for generalist lawyers who need a reliable route through corporate, securities, tax, and IP issues that intersect at every step. The guidance reflects mainstream U.S. venture practice; specific facts, states, and deals will vary, and securities and tax outcomes in particular should be confirmed with specialist counsel.

A theme runs through every stage: clean paper compounds. Diligence in a Series A or an acquisition reaches back to formation. The cheapest time to get the entity, equity, IP, and securities compliance right is at the beginning.

A second theme is sequence. The stages below are roughly chronological, and the order is not arbitrary—it tracks the order in which value and risk accrete. You cannot sensibly issue founder stock before you have an entity to issue it from; you should not take outside money before founder equity is vested and IP is assigned, or your first investor inherits an unstable foundation; and you cannot run a clean priced round on top of a cap table you never maintained. Founders who skip ahead—raising money on handshake terms before incorporating, for instance—create cleanup work that costs far more than doing the steps in order. Use this toolkit as a sequence as much as a menu.

Roadmap at a glance

  1. Entity choice and formation. Pick the right structure (usually a Delaware C-corporation for venture-track companies) and form it correctly.
  2. Founder agreements and equity. Allocate equity, impose vesting, and document the founder relationship.
  3. IP assignment. Move all relevant intellectual property into the company.
  4. SAFEs and convertible notes. Raise early money on convertible instruments.
  5. The priced seed round. Convert to a priced equity round with real investors.
  6. Cap table management. Keep ownership accurate and clean as it grows.
  7. Securities exemptions. Stay inside Regulation D and related exemptions on every raise.
  8. Later rounds. Bring on new investors and manage the evolving capital structure.

Stage 1 — Entity choice and formation

The first decision is structural: what kind of entity, in what state. Most companies pursuing venture capital and stock-option compensation form as Delaware C-corporations, because investors expect Delaware's developed corporate law and because the C-corp structure cleanly supports preferred stock, option pools, and the Section 1202 QSBS tax benefit (Stage 7). LLCs and S-corps suit many small businesses and bootstrappers but create friction for institutional equity financing. The choice is not purely legal—it has major tax consequences—so loop in a tax adviser before incorporating.

Forming correctly means more than filing a certificate of incorporation. You also adopt bylaws, appoint initial directors and officers, authorize and issue founder stock, set up the option pool, and hold organizational consents. Founders who incorporate themselves online frequently leave these steps half-done; the gaps surface in financing diligence.

Stage 2 — Founder agreements and equity

Once the entity exists, paper the relationship among the people who will own and run it. The central instruments are the founder stock purchase agreements (issuing shares, usually for nominal cash or assigned IP) and a founder/restricted-stock agreement that imposes vesting—typically a four-year schedule with a one-year cliff. Vesting protects the company and the remaining founders if someone leaves early, and investors will insist on it. Document roles, decision rights, and what happens on departure before there is a dispute, not after.

Two tax points are critical here and easy to miss. First, founders who receive restricted stock subject to vesting should usually file an IRC Section 83(b) election within 30 days of the stock grant, electing to be taxed on the (tiny) value at grant rather than on the (potentially large) value as it vests. Miss the 30-day window and there is no fix. Second, structure founder stock so it can qualify for Section 1202 QSBS treatment down the road (Stage 7).

Illustration. Two founders split equity 50/50 with no vesting. One leaves after three months to take a job. Without vesting, she keeps her full half of the company forever—and the remaining founder must build the entire business while she holds a passive 50%. Standard four-year vesting with a one-year cliff would have returned nearly all her shares to the company.

Stage 3 — IP assignment

A startup's value is usually its intellectual property, and that IP must live inside the company, not in a founder's or contractor's personal account. Every founder, employee, and independent contractor who touches the product should sign a Confidential Information and Invention Assignment Agreement (CIIAA) or equivalent, assigning to the company all inventions and work product and protecting confidential information. Founders should also assign any pre-existing, company-relevant IP they bring in. Missing assignments—especially from early contractors—are one of the most common and most damaging diligence findings.

Get the drafting right for enforceability: invention-assignment clauses interact with state statutes (for example, California Labor Code § 2870, which carves out certain inventions developed entirely on the employee's own time) and with the founders' prior employers' agreements. A clause that overreaches can be partly unenforceable.

Stage 4 — SAFEs and convertible notes

Early-stage companies usually raise their first outside money on convertible instruments rather than priced equity, because they defer the hard question of valuation and close quickly and cheaply. The two main instruments are the SAFE (Simple Agreement for Future Equity, originated by Y Combinator) and the convertible note. Both give the investor the right to convert into equity at a future priced round, typically with a discount and/or a valuation cap. The key difference: a SAFE is not debt—no interest, no maturity date—while a convertible note is a loan that accrues interest and matures, adding pressure if the next round is delayed.

Founders should model the dilution these instruments create. Multiple SAFEs with different caps stack up, and at conversion they can claim more of the company than founders expect—especially post-money SAFEs, which fix the investor's ownership percentage. Run the math before signing, and understand whether caps are pre-money or post-money.

Illustration. A founder sells $2M of post-money SAFEs at a $10M cap, assuming "20% dilution." But because post-money SAFEs are calculated after including all SAFE money, and because the option-pool increase and the priced round dilute the founders (not the SAFE holders), the founder's actual post-financing ownership can be meaningfully lower than the back-of-envelope guess. Modeling the cap table avoids the surprise.

Stage 5 — The priced seed round

At some point the company raises a priced round: investors buy newly issued preferred stock at a negotiated valuation, and the convertible instruments from Stage 4 convert into that round. A priced seed introduces the full set of venture documents—a stock purchase agreement, a certificate of incorporation creating the preferred class, an investor rights agreement, voting and co-sale agreements—and real governance terms: a board seat or observer, protective provisions, information rights, pro rata rights, and liquidation preferences. Many seed deals use standardized forms (such as the NVCA model documents or Series Seed templates) to reduce cost and friction.

Preparation matters as much as negotiation. Investors will run diligence on everything done in Stages 1–4, so a company with clean formation, vesting, IP assignments, and securities compliance closes faster and on better terms. This is the payoff for getting the earlier stages right.

Stage 6 — Cap table management

A capitalization table records who owns what—founders, option holders, SAFE/note holders, and preferred investors—on both an issued and a fully diluted basis. As instruments stack and rounds close, the cap table becomes the single source of truth for ownership, dilution, and control, and errors in it derail financings and acquisitions. Keep it current, reconcile it to the actual signed documents, and model how each new instrument and option grant affects everyone's percentage. Many companies move to cap-table software (Carta, Pulley, and similar) early to maintain accuracy.

The cap table also drives the option pool. Investors typically require a pool sized for the next 12–24 months of hiring, and whether that pool is created pre- or post-money materially affects founder dilution—negotiate it consciously.

Resources

Stage 7 — Securities exemptions

Every issuance of stock, SAFE, or note is a sale of securities and must either be registered with the SEC or fit a registration exemption. Startups raise privately, so they rely on exemptions—overwhelmingly Regulation D, Rule 506(b) (no general solicitation; unlimited accredited investors plus up to 35 sophisticated non-accredited investors) or Rule 506(c) (general solicitation permitted, but all investors must be verified accredited). After a Rule 506 sale, the company files a Form D notice with the SEC (electronically through EDGAR) within 15 days of the first sale, and makes any required state "blue sky" notice filings.

Getting this wrong is serious: an unregistered, unexempted sale can give investors rescission rights and expose the company and its principals to liability. Practical guardrails: confirm each investor's accredited status (and verify it under 506(c)), avoid general solicitation under 506(b), use proper subscription paperwork, and file Form D on time. Two tax benefits ride alongside: founders and early investors holding qualifying C-corp stock for more than five years may exclude gain under IRC § 1202 (QSBS), and the § 83(b) election from Stage 2 protects equity recipients—both reward getting the structure right early.

Stage 8 — Later rounds

As the company grows it raises additional priced rounds (Series A and beyond), each adding a new class of preferred stock, new investors, and re-negotiated terms—board composition, protective provisions, liquidation-preference stacks, anti-dilution adjustments, and pro rata participation by existing investors. Each round triggers the same securities-exemption discipline (Stage 7), updates the cap table (Stage 6), and reaches back into diligence on everything done before. Founders should understand how preferences stack and how new money can re-cut control and economics, and should plan financing as a multi-round arc rather than a series of disconnected events.
