An A-thon style fundraiser is a type of event where participants engage in an activity for an extended period or aim to complete a specific challenge, often measured by time, distance, or quantity, while raising money for a cause. The name comes from events that typically end with "-thon" (e.g., marathon, walkathon, read-a-thon).

In these fundraisers, participants ask for pledges from friends, family, or sponsors who pledge a certain amount of money per unit of activity (e.g., per mile walked, per book read, or per hour danced). The more the participants achieve, the more money they raise for the cause.

BetterWorld's A-thon tool simplifies the fundraising process by allowing donors to easily pledge per activity, such as per mile walked or per book read. At the end of the event, the tool automatically calculates the total and charges donors, streamlining the payment process for organizations. This makes it hassle-free for both participants and donors to support a cause.

These fundraisers are popular because they encourage community involvement, can be adapted for many causes, and motivate participants through physical or mental challenges.
