Complete co-founder playbook for technical founders — finding co-founders, equity splits (dynamic and static), co-founder agreements, vesting schedules, working relationships, conflict resolution, co-founder breakups, and the "dating before marrying" framework. Use when looking for a co-founder, structuring a founding team, negotiating equity, or navigating co-founder relationship challenges. Covers YC advice, First Round, and a16z resources.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Co-Founder Dynamics

## Overview

The co-founder relationship is the #1 predictor of startup success or failure —
ahead of product, market, or funding. YC data shows that co-founder conflict
is the leading cause of early-stage startup death. The mistake: choosing a
co-founder based on friendship or availability instead of complementary skills,
aligned values, and tested working relationships. This skill covers finding
co-founders, structuring equity, drafting agreements, building trust, and
navigating the hard conversations before they become fatal.

## When to Use

Trigger phrases: "find a co-founder", "co-founder equity split", "co-founder
agreement", "technical co-founder", "business co-founder", "co-founder
dynamics", "should I have a co-founder", "solo vs co-founder", "co-founder
breakup", "vesting schedule for founders", "founder prenup"

## Authoritative Foundations

market issues. The "Rich vs. King" dilemma: every founder must choose

How to install

The exact contents, by fingerprint
mdr add leadmagic/gtm-skills/co-founder-dynamics@sha256:ebd189487a02213a

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
