founder-agreement-drafting-stephane-boghossian

A drafting-and-review copilot for a founders' / co-founders' agreement — the terms fixing equity, vesting, IP, roles, control, deadlock, and departure between cofounders. Jurisdiction-agnostic, anchored on the Delaware C-corp default. Two modes: DRAFT (intake → equity & vesting → clauses → blocker triage → pre-signature check) and REVIEW (audit an existing agreement against an 18-clause checklist and red-flag scan). It handles the highest-dispute terms first-class: the equity split as documented reasoning (not a fake calculator), reverse vesting and the 83(b) clock, present-tense IP assignment

What it does

A drafting-and-review copilot for a founders' / co-founders' agreement. It guides the user through identifying founders, selecting the appropriate instrument based on entity/jurisdiction, and building an equity and vesting architecture. It emphasizes drafting for the venture as a whole, not one founder, and provides a structured intake, mapping, and justification process. It supports two modes: DRAFT (intake → equity & vesting → clauses → blocker triage → pre-signature check) and REVIEW (audit an existing agreement against an 18-clause checklist and red-flag scan). It highlights handling high-dispute terms like equity split, reverse vesting, 83(b) clock, IP assignment, leaver provisions, and deadlock. It also references a broader methodology and references to local counsel for jurisdiction-specific terms.

How it works

  • Phase-based workflow: Phase 1 intake and founder mapping; Phase 2 equity & vesting architecture; Phase 4+ (implied in description) further drafting and triage. It produces artifacts such as a founder-and-role map, entity/jurisdiction determination, and a contribution inventory feeding Phase 2.
  • Step 1 establishes who is a founder and reconciles independent founder views.
  • Step 2 determines entity and jurisdiction to decide the instrument (Delaware C-corp defaults lead to RSPA + CIIA/PIIA + bylaws; alternatives for LLC, UK Ltd, MENA variants).
  • Step 3 builds a contribution inventory to inform the equity reasoning in Phase 2.
  • Step 4 reasons the split using Wasserman/NBER critique and YC guidance, yielding a defensible rationale behind the chosen split and vesting approach.
  • It forbids output of a false-precision percentage from a formula and requires written rationale behind splits.

When to use it

  • Use for starting a founders' agreement in a Delaware C-corp context or when mapping terms across instrument rails.
  • Use when you need to justify equity splits with a written rationale, not just numbers.
  • Use in either DRAFT — full walk-through or REVIEW — audit mode to identify gaps against a checklist.

What it can touch

  • Tools: Read, Write, Edit, WebFetch, WebSearch.
  • It references entities, instruments, and terms like RSPA (equity+vesting) and CIIA/PIIA (IP) and bylaws for governance, under a Delaware default.

Caveats

  • Jurisdiction-specific enforceability and tax implications are flagged to local counsel; the method does not certify enforceability.
  • It requires explicit independent counsel for founders; outputs are neutral scaffolds, not legal advice.
  • It emphasizes not outputting a precise numeric split without a written rationale and does not compute a precise percentage from a formula.

# /founder-agreement-drafting — Founders' Agreement Drafting & Review Method You are a **drafting-and-review copilot for a founders' agreement** — the set of terms that governs equity, vesting, IP, roles, control, and departure among the people starting a company. You work for **the venture as a whole**, the way company counsel does — not for any single founder against the others, and never as a substitute for the parties' own lawyers. A "founders' agreement" is a **category of terms, not one standard instrument**. US market practice often scatters those terms across a Restricted Stock Purchase Agreement (equity + vesting), a Confidential Information and Invention Assignment Agreement / CIIA (IP), and the bylaws (governance), with a standalone founders' agreement used mainly as the **pre-incorporation bridge** before those documents can exist. For an LLC the operating agreement *is* the founders' agreement; for a UK Ltd it is the Articles of Association plus a Shareholders' Agreement. Your job is to get the substantive terms right and draft them into **the instrument the entity type and stage actually call for** — not to insist on one magic document. (See [`REFERENCE.md`](./REFEREN

What's inside
Steps it walks through
  1. The Scope Gate (read at the start of every engagement, never skip)
  2. Operating principles (the spine that runs through every step)
  3. How to drive this skill
  4. Step 1 — Establish who is a "founder", and elicit each one
  5. Step 2 — Determine the entity and jurisdiction (this selects the instrument)
  6. Step 4 — Reason the split (and write down why)
  7. Step 5 — Set the vesting (this is the term that actually protects everyone)
  8. Step 7 — Set acceleration (default double-trigger)
  9. Step 8 — IP assignment (the non-negotiable one)
  10. Step 10 — Leaver provisions & buyback (draft the exit before the honeymoon ends)
  11. Step 12 — Wire in the supersession / termination clause
  12. Step 13 — The pre-signature checklist (the diligence dry-run)
  13. Step 14 — Close open blockers as conditions, and hand off
  14. The 18-clause presence check

How do I install it?

Run `npx skills add lawve-ai/awesome-legal-skills --skill founder-agreement-drafting-stephane-boghossian --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From lawve-ai/awesome-legal-skills, a repository with 618 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
