GFTG Companion | Event platform for a 400-person conference

Go for the Greens is a business development conference that has been bringing women business owners together since 2007. The 2026 edition ran September 30 – October 3 at Disney's BoardWalk Inn in Orlando: about 400 attendees, four days of sessions, golf and networking.

GFTG Companion is the digital platform we built for it — three apps on one shared backend, live at event.goforthegreens.org. Attendees got the whole conference in their phone, organizers got one place to run it, and volunteers got a check-in scanner that works without the internet.

The organizers came with four goals. Put the program, the attendee directory and the badge in every attendee's phone. Help people meet the right people — and explain why they should. Let a small organizer team run the entire event from one place. And check people in at the door even when the venue Wi-Fi gives up.

And one rule above all: most attendees are women over 50, and many of them are wary of new apps. So no passwords, big buttons, plain words. If something needs explaining, it's designed wrong.

We designed and built three products that share one backend and one source of truth: a mobile web app for attendees, a desktop console for organizers and an offline check-in scanner for volunteers. Tickets flow in from Eventbrite automatically, every change an organizer makes shows up in the attendee app right away, and every scan at the door lands back in the console.

Signing in takes one tap on a personal link from a welcome email — nothing to remember, nothing to reset. Everything else follows the same idea: fewer steps, larger targets, words people actually use.

A passwordless mobile web app with the full four-day agenda — filters by day and track, search, a "happening now" view and add-to-calendar. A personal schedule warns about conflicts and can be subscribed to from any calendar app. A five-step profile captures industry, interests, goals and certifications. Plus the attendee directory, announcements, venue and hotel maps, and speakers.

The heart of the platform. It matches attendees by interests, industry, goals and certifications — and tells them why, in human words: "You share an interest in government contracting, you're both Women-owned certified, and you both came for mentorship."

Matching is fair by design: a round-robin that starts with the people who have the fewest matches, so nobody is left out. It never pairs colleagues from the same company. And nothing reaches attendees until the organizers have reviewed it.

One desktop window for the whole event. A dashboard with attendees, tickets, profile completion and open issues. Automatic import from Eventbrite. Attendee management with search, filters, manual add, duplicate merge and deactivation. Editing for the agenda, speakers, days and home-screen tiles. Emails and announcements with preview and test send. QR badge preparation with a print-ready PDF. Roles for admins, editors and volunteers — and an audit log of every change.

A volunteer scans the QR badge, the screen turns green with the attendee's name, and check-in takes a second. The scanner works offline: the guest list is stored on the device and syncs when the connection comes back. It handles re-entry, revoked badges, refunded and unnamed tickets, and counts one check-in per day. No emails, phone numbers or addresses are ever stored on the device.

Branded welcome emails with a personal sign-in link, sent in the background with live progress and never a duplicate. A reminder email with a welcome video and deep links straight into the app — to the video, the survey or the home screen. One-click unsubscribe that stops the emails but never takes away access to the app.

GFTG Companion ran live through the entire conference. For the first time, the organizers ran the whole event from one window. Attendees arrived already knowing whom to meet and why. Volunteers checked people in with a single scan.

The feedback from organizers, attendees and volunteers alike was the best part: for an audience that is usually wary of new apps, it was a genuine "wow".
