Say goodbye to event chaos

Our fundraising event software helps you eliminate disconnected tools, manual spreadsheets, and event-day confusion so you can execute flawlessly when it matters most.

Simplify ticketing, registration, and check-out

When your auction is a high-visibility moment with no do-overs, the last thing you need is a patchwork of tools that creates long lines, confused guests, and last-minute fire drills for your team and volunteers. Guests move seamlessly from arrival to giving without friction, and your team closes out events faster with in-product reconciliation.

Track participation, revenue, and donor activity as it happens. Real-time dashboards give you visibility into performance so you can adjust appeals, monitor progress toward goals, and confidently report results to leadership.

Create more engaging, accessible events

Enable supporters to bid, donate, and participate from their own devices without downloading an app. Mobile-first experiences keep guests engaged and giving, whether they’re in the room or joining remotely.

Surpass your fundraising goals

Drive higher revenue with sponsorship management, paddle raises, fixed-price items, raffles, and Event Ambassador Fundraising tools that extend giving beyond the event itself. Built-in analytics and AI recommendations help you prepare smarter and raise more over time.
