Meaning
Calculations that reduce an individual’s percentage of ownership relative to the specific portion of their time or capital committed to a project define the cost of divided loyalty. Application of fractional dilution occurs when a founder transitions from a full-time role to a part-time or advisory position. The mechanism adjusts the vesting schedule or the final equity grant to match the actual contribution delivered over the life of the firm.
It applies only to the unvested portion of the equity and does not affect shares already earned through past service.
Ownership Calculus
Adjusting the equity stake based on time commitment requires a clear definition of what constitutes a full-time effort. This standard is often measured in hours per week or the completion of specific milestones tied to a project plan. When the person falls below the threshold, the math of the dilution starts to reduce the future ownership grant automatically.
Equity Compression
Accepting a reduced stake in exchange for more freedom costs the person long-term influence over the direction of the company. This trade-off is often the only way to balance multiple professional interests without violating other legal agreements. The load is the loss of potential wealth and the reduction in voting power during critical board decisions.
Participation Floor
Minimum levels of engagement are required to keep any equity stake at all in many high-growth environments. If the participation drops below this floor, the person may lose their board seat and all remaining unvested shares. This boundary ensures that the core team remains focused on the survival and success of the venture.
