Season One · 2026
Are you up for the challenge?
7 months. 10 chapters. 10 chances to make the deepest connections with founders who decide to suffer through something together and come out the other side. Not networking. Not a retreat. A season of challenges that leaves you with a stronger version of yourself and the people who saw you get there.

Hard Hikein Yosemite.
YOSEMITE NATIONAL PARK, CA
Twenty miles, six thousand feet, one day. There's a stretch in the middle where you'll wonder why you came — and then the person next to you keeps walking, so you do too. We start in the dark and finish a little changed.

Dirt Biking Training Dayin South Bay.
SOUTH BAY, CA
None of us could ride when we started either. You spend the day with patient, genuinely good instructors, drop the bike a couple times, and by evening you can ride. The easiest way in - and how you get ready for Tahoe.

Fly Fishingin Sierra Nevada.
SIERRA NEVADA, CA
Quieter, colder, harder than it looks. You wade in, you learn a skill that humbles everyone equally, and you stand in moving water until something clicks. Guides and gear provided. Patience is on you.

Dirt Biking Adventurein Tahoe.
LAKE TAHOE, CA
High-altitude trails and hills that many people don't think they can climb. Then someone goes first, and you find out you can too. Adventure riding, views you have to earn, and a group that's as excited as you are.

Raftingin Wine County.
AMADOR COUNTY, CA
A raft doesn't move unless everyone pulls - that's the whole point. You'll get cold, soaked, and loud, and by dinner that night you'll know these people better than you planned to.

Hawaiiin Pacific.
HAWAIIAN ISLANDS
The one we save for the end of the season: a week with the people you spent the year getting to know. You've probably been to Hawaii. You haven't been like this. Members only.
