Vesting is a reasonable approach, but it comes with its own baggage. One year cliffs are somewhat arbitrary -- afterall, why does a gregorian calendar dictate when ownership is divided? There's room for more granularity than that. What do you do with someone who needs to take a sabbatical for health or family even though they were outstanding contributors early on? What about someone who comes in several months after the original founders, but has great performance? You don't necessarily deserve more just because you were there on day 1. Dynamic splits account for all these scenarios plus more without overcomplicating the initial paperwork.

I believe "hours clocked" was only one of the contributions included in the model.

From the article:

> "Basically, Moyer’s idea assigns monetary value to every tangible and intangible contribution individuals make to a startup, from intellectual property and relationships to time and cash."

Depends. If you invest a ton of time developing something but you pivot, whoever invested the most time on that gets fucked hard. If they contributed a lot to the pre-pivot effort, that should be accounted for somewhere for something.
