A lesson on structure and ownership before anyone drafts a document. It compares legal form categories by what they do, reviews research on solo versus team founding, equity splits and founder control, and explains vesting, IP assignment and early-employee equity as concepts.
Questions and answers
Questions a learner would ask about this lesson. Think through your own answer before you open each one.
- Why doesn't the course just name the best legal form?
Show answer
Every country names its legal forms differently, names can mislead across borders, and tax treatment depends on the country rather than the form category. The course teaches seven dimensions instead: liability, ownership and transfer, governance, profit treatment, capital and donations, mission lock, and administrative burden. Which form fits is a question for a local lawyer and accountant.
- Do solo founders do better than teams?
Show answer
The evidence is narrower than that. In Greenberg and Mollick's data on Kickstarter project creators from 2009 to 2015, solo creators were more likely to keep an ongoing for-profit venture going, but teams did better for nonprofits. It is an association in one population, and it cannot tell anyone whether they should found alone.
- Is an equal equity split a mistake?
Show answer
The research does not say so. Hellmann and Wasserman found that about one third of founding teams split equally, often quickly, and equal splits were associated with lower first-round valuations. The authors attribute this to hidden team differences, not the split itself. The lesson suggests a structured conversation on contributions, roles, future commitment and timing instead of a quick default.
- What is dead equity, and how do founders commonly address it?
Show answer
Dead equity is ownership held by someone who no longer contributes, often because they left early. Vesting, where a person earns full rights to their equity gradually over time or at milestones, plus cliffs and leaver terms, are the common concepts. Four-year vesting with a one-year cliff is a convention in some venture markets only; terms are negotiated.
- What should I understand about an offer of "some equity" as an early employee?
Show answer
The lesson treats it as a set of questions: shares now or a right to acquire later, how much out of how many in total, what vesting, cliff and leaver terms apply, and what happens when new investors join. Receiving shares and moving IP into a company can also have tax consequences, sometimes with short deadlines, so the referral trigger is to ask a local tax professional whether any deadline applies.
