Referral mechanisms

Dropbox’s registration statement describes sharing and referrals as acquisition routes, and separately describes prompts, trials and lifecycle marketing for paid conversion. The actor’s choice creates a route from an existing participant to a recipient. That recipient may arrive to obtain a file, respond to a recommendation or seek a reward; those purposes can produce different later use. The operating decision is what useful action the referral enables and whether the recipient would have arrived anyway. An incentive can improve reach while attracting duplicate or short-lived accounts. Removing the incentive can reduce abuse while also weakening a useful invitation path. These are analytical alternatives, not an internal experiment reported in the filing. Registration stocks and active paid-license stocks have different units; the self-service share of revenue does not identify the share of referred signups. Trace a relevant exposure to the recipient’s useful task and retained use, then include incentive and service costs. The public disclosure establishes the route and its acquisition risk, not an incremental referral return.

Atlassian’s acquisition activity shows an online evaluation route under defined counting rules. It does not trace a recommendation to activation or purchase. A referral program would require that additional exposure and outcome evidence.
