Culture & Values

  • Customer first

    We always put our customers first. Klaviyos start with the customer and work backward. We create products that solve legitimate customer problems, always doing what's best for our customers and their customers. We work hard to earn and keep each customer's trust through products and experiences that improve their lives and speed up their paths to success.

  • Always learning

    We are always learning. “We surround ourselves with people that are intensely curious and energized by learning. I know many Klaviyos who have attended Udemy courses, coding academies, conferences, and university classes to better themselves and I know others that have independently launched internal trainings and mentoring programs to help teach others. It helps that we have a free book policy and generous learning stipend but what makes Klaviyo really special is the culture of putting this into action.” - Mike Parker, Sr. Director, Solution Architecture Klaviyos have a constant desire to learn and a powerful drive to “figure things out.” We’re high-slope and have a relentless curiosity that allows us to uncover and solve the world’s hardest problems. As individuals, we’re knowledgeable about many things, not just one. And when we don’t know something, we’re expected to learn and become an expert for others.

  • Equitable world

    We strive to make the world more equitable. “Klaviyos come from all over the world, and have all kinds of backgrounds. We have a number of employee-organized groups called KRGs that celebrate our different backgrounds, identities, and values. Because wherever you're from, you belong here.” - Hansen Liang, Senior Product Manager Klaviyos believe that everyone deserves a fair shot at success. We treat people both inside and outside of Klaviyo with equity, respect, honesty, and kindness. We strive to build a diverse company, and prioritize the inclusion of varied opinions and experiences throughout Klaviyo. We aren't afraid to speak out when we see injustice. We create products and programs that can provide everyone, everywhere with tools for ownership and success.

  • Collaborate radically

    We collaborate radically. Klaviyos are what we create together. We are humble, transparent, and on a lifelong journey to become better humans together. We express strong opinions with kindness and proactively seek feedback. We listen, share, encourage, and trust each other. We’re quick to admit when we’re wrong, and even quicker to help one another win. No task is below us—we’re as willing to ship packages as we are to set strategy. Our strict “no brilliant jerks” policy helps us recruit, hire, and retain exceptional collaborators.

  • Ambitious

    We are ambitious. “Klaviyos dream big and are passionate. We don't back down from challenging problems. We don't fear failing. We strive to succeed and build success for those around us. We don't limit our thinking to "what we've always done." We are builders and we create opportunities.” - Daniel Kezerashvili, Engineer Manager II Klaviyos don't limit themselves to the tools and solutions of today. We dream big and aim to solve the hardest of problems, problems that pull future technology into today. All of us are inventors and entrepreneurs, and together we create the best solutions for customers, even when that means tackling tough obstacles. Experimentation, failure, fast iteration, and big wins are all valued equally in our culture of problem-solving.

  • Remarkable

    We are remarkable. “I am always impressed by the unique skills and talents held by people at Klaviyo and the drive Klaviyos possess to go above and beyond. By bringing their best to work everyday in meaningful and noticeable ways, Klaviyos inspire others to do the same.” - Evan Eisert, Group Product Manager Klaviyos deliver work that is deemed “remarkable” by our peers, our customers, and the market. We start by focusing on quality of work, then learn how to do it faster, frugally, and more efficiently. We are meticulous in each action we take as individuals and as teams. We are rigorous, prepared, and high-performance. We know the “why” behind each problem and goal, and we stay close to the decisions we make to ensure the most remarkable outcome.
