Steve Arntz

Founder, Advisor

As a Founder Advisor at Sandbox, I work with undergraduate founders as they build and scale early-stage companies. My role focuses on helping founders develop the leadership skills required to build strong teams, navigate conflict, communicate clearly, and make thoughtful decisions under pressure. I teach and facilitate sessions on leadership, team dynamics, and hard conversations, supporting founders as they move from individual contributors to leaders responsible for others. The work closely mirrors the challenges managers and leaders face in growing organizations: setting expectations, giving feedback, building trust, and creating healthy team cultures. This role reinforces my belief that leadership development must start early, be grounded in real work, and focus on the moments that matter most. It strengthens the same leadership muscles I build through Campfire, applied in an environment where learning, experimentation, and growth happen fast.

Co-Founder, CEO

Campfire helps growing, distributed organizations build confident, capable leaders at scale. We partner with lean People and Talent teams to run leadership and manager development that works in the real world. Our approach goes beyond one-off workshops and does not rely on heavy customization or additional headcount. Our work is grounded in a simple belief: managers are the primary lever for performance, culture, and change. Campfire supports managers in the moments that matter most, including effective 1-on-1s, delivering challenging feedback, navigating change, setting expectations, and supporting well-being. We make development practical, repeatable, and easy to integrate into the conversations and work that are already happening. As CEO and Co-Founder, my role is to shape Campfire’s vision, build systems that scale, and partner closely with customers to ensure our programs drive real outcomes. I spend my time working with HR and Talent leaders to design development that fits their reality, supporting our team to do the best work of their lives, and helping organizations turn leadership development into an operating system—not a one-time event.

Director, Digital Product Strategy

At Instructure, I worked at the intersection of product strategy, leadership development, and organizational effectiveness during a period of rapid growth. My role focused on designing and scaling people-centered systems that helped leaders and teams perform, align, and grow in a complex, fast-moving organization. Alongside product strategy work, I partnered closely with leaders and executives on talent development, performance management, and culture as the business scaled from $0M to $27M in revenue and supported customers including Tesla, Disney, Lululemon, and Slack. This included supporting manager capability, contributing to engagement and culture initiatives, and helping align talent strategy with business priorities. I also spent significant time writing, speaking, researching, and facilitating conversations focused on leadership, growth, and how people do their best work. This experience shaped my belief that leadership development must be practical, embedded in real work, and designed to scale. It laid the foundation for the work I do today building systems that help managers and leaders show up better in the moments that matter most.
