Develop
Learn how to think, communicate, and lead at a higher level.
Zac & Jill Newell · One Development Group
We develop driven professionals into leaders, expand their income streams, and produce long-term optionality — alongside the careers they’ve already built.
You don’t need to start over to build something more.

Who we are
We’re partners in life and in business — focused on leadership, communication, and building things that last.
Our work lives at the intersection of personal growth and practical execution. Not theory. Not hype. Real people, doing real work, over time.

What we do
Through mentorship, skill development, and a performance-driven environment, we guide qualified people in building an additional platform for income, leadership, and long-term growth — alongside their existing career.

Over time, it becomes:
The type of person this works for
This tends to resonate with people who are already doing well…
But can’t ignore the feeling that there’s more.
More upside. More control. More freedom in how life actually plays out.
Not because something is broken — but because staying on one path no longer feels like enough.

Built over time
Mentoring hundreds of individuals across multiple markets. Building scalable organizations over time. Speaking to audiences around the world on leadership and growth.
What we’re built on
Ownership
We take responsibility for outcomes — good or bad.
Leverage
We build things that scale beyond our own effort.
Excellence
We don’t settle for average — especially from ourselves.
