Our values
Lean into moonshots
We don’t settle for incremental change. We have the bravery to take risks and shoot for the impact we want to have.
Opportunity is at the intersection
We lean into combining disciplines, expertise, and perspectives not normally adjacent. We design our organization to facilitate cross-pollination and cross-collaboration. We reject silos.
Expertise without ego
Titles do not determine who has a voice. We work on hard, technical problems and have a ton of fun while at it.
Learn by doing
Our path is novel and many things we’re doing have never been done before. We lean into MVPs and are open to unexpected outcomes.
Lead with context
We equip people with the context and background necessary to make their own decisions and act in the best interest of Loyal. Empower team to succeed.
Empathy and respect for all life
Our patients are not just numbers. Our work is intentional, thoughtful, and guided by respect for life. We take our responsibility to pets and pet parents seriously.
