Vesting Acceleration (Single vs Double Trigger)
Quick definition
Provisions that accelerate unvested equity on change of control or termination.
SINGLE TRIGGER: unvested shares accelerate on ONE event (typically change of control / acquisition). Most founder-friendly but VC-disfavored. DOUBLE TRIGGER: requires TWO events: change of control + involuntary termination without cause. Standard in institutional rounds. Variants: 100% double trigger (full acceleration), 50%/100% (partial on CIC + full on termination), 12-month acceleration (fixed amount). 'Cause' and 'good reason' definitions are heavily negotiated; narrow 'cause' + broad 'good reason' favors founders.
