Our Philosophy

At Chicory, we know that we are strongest when every person is valued, respected and treated with dignity. We actively put aside assumptions and judgment and work to make space for all points of view. We do serious work but don’t take ourselves too seriously. We consider our playful spirit a competitive advantage to building better relationships and finding the smartest solutions. We produce the best results by hiring smart people and giving them the space, safety and the resources to do their work. We are building a company people love working with and working at.

Our Commitment Statement to Diversity, Equity, Inclusion, & Belonging

At Chicory, diversity, equity, inclusion, and belonging are key ingredients in our recipe for success. Our diverse experiences, backgrounds, identities, and ways of thinking elevate the level at which we operate; this allows us to innovate in old-school industries by looking not at how things have been done, but how they should be done. We are building a workplace built on merit and equity where every one of us has a voice at the table. 

Our Principles

• Be Good People: The success of our company is totally dependent on having good, smart people.
• Own It: We take pride in our work. When we see a problem, we step up. We hold ourselves, and each other, to the highest standard. We learn from mistakes, admit when we are wrong, and take full responsibility for delivering results, not just for our role, but for the mission.
• Separate Your Ego From Your Position: We speak up with conviction, but we stay open to being wrong. Leadership isn’t about winning arguments or defending turf; it’s about serving the mission. We challenge ideas without taking it personally, and we invite feedback without getting defensive. Our goal is the best outcome, not to “be right.”
• Find Reality: We pursue truth over comfort. We seek to understand before insisting on being understood. We dig beneath symptoms to uncover root causes, and we challenge assumptions, even our own. Clarity comes from curiosity, not certainty. We don’t settle for surface-level answers. We seek reality, even when it’s inconvenient.
• Have a Beginner’s Mind: Just because something has been done a certain way doesn’t mean it’s the best way. We stay curious, challenge assumptions, and question the status quo. We stay innovative by tackling problems from a fresh perspective.
• Bias for Action: Speed matters in business. We don’t wait for permission, perfect clarity, or endless alignment. We cut through noise, complexity, and politics to drive progress. When in doubt, we act, learn, and adapt because action beats indecision every time.
• Customer Obsessed: Our customers are our North Star. We listen closely, dig deep to understand their needs, and deliver 5-star service at every touchpoint. We build products that actually work: simple, intuitive, and designed to solve real problems.
• Above and Beyond: We don’t settle for “good enough,” we aim for exceptional. We go above and beyond what’s expected for our team, our customers, and ourselves. We stay curious and hungry. Every day is an opportunity to get better.
