Mastermind19 is a private, invitation-only club for golfers who build businesses — and the app is where the membership lives.
GOLF TRIPS
Browse the season's curated trips to premier courses across the country. Book your spot in seconds, add a guest, choose your upgrades, and pay with your member wallet or card on file. Every detail — itinerary, hotel, courses, tee times — lives in your pocket.
THE M19 CUP
Every event counts. Follow the season-long M19 Cup standings, track your position in the Gross and Net divisions, browse past seasons, and count down to The Championship.
COMMUNITY
A network worth the trip. Share wins in the community feed, find members by market or industry on the member map, and join industry groups that match your world.
MESSAGES
Direct messages, group chats, and event chats that bring each trip's group together before you arrive — planning, travel coordination, and tee-time talk included.
MEMBER WALLET
Load credit, track every transaction, and book trips without pulling out a card. Your balance, your history, all transparent.
CLUB SHOP
Member merchandise, shipped to your door.
BRINGING A GUEST?
Guests invited on a trip get their own app access for the event — the group chat, the scorecards, the full experience.

Faster everywhere. We rebuilt how the app moves between pages — switching tabs, pulling to refresh, and browsing the map are all noticeably smoother.
Videos in messages. Send videos up to 5 minutes — they attach instantly, send reliably, and play for everyone, including members on desktop.
Notifications take you to the right place. Tapping a push about a trip now opens that exact trip, not just the trips page. Banners do the same.
Golf trips. The featured trip now sits at the top with a gold highlight, and trip pages open and close more smoothly.
Tagging cleaned up. Type @ to tag someone — tags are blue and tap through to their profile. Casually typing a name no longer pings anyone.
