We founded Klaviyo to give businesses the infrastructure to store everything they know about their customers and use that information to deliver stunning, individualized experiences at scale to each of their customers, as if each customer was their first and most important. Ed and I were entrepreneurs, we knew what personal touch meant and the power it has. Allowing businesses of all sizes to “be yourself at internet scale” was our pitch.
We’ve made tremendous progress against this goal. We now serve over 180,000 businesses around the world and just powered 22B+ messages personalized in real-time that led to $3.8B in attributed revenue. And, yet, we’ve scratched the surface of what we can do.
Today, I’m incredibly excited to share that Chano Fernández will be joining Klaviyo as my co-CEO. I met Chano two years ago when Klaviyo was half the size it is today. I was fascinated by his experiences scaling Workday and asked if he’d join our Board. Over lunches and dinners in Boston and London, he’s taught me about scaling a global business, I taught him our customers, products and business, and we developed a deep respect for each other’s intensity and intellect.
A year ago, I shared with Chano and our Board that LLMs and the current wave of AI were going to create a step change in how businesses defined customer experiences. Instead of our users needing to program and configure experiences on our data and messaging infrastructure themselves, increasingly algorithms and agents would be able to draft, execute and optimize those experiences for them. Any business could plug into Klaviyo, deliver better customer experiences and grow faster.
We’ve hit a critical stretch where an agentic layer that can drive our B2C CRM is no longer a research project, it’s production grade. We have the opportunity to make rapid progress, usher in this new era for the businesses we serve and lead it. I shared this with Chano a few months ago, asked his advice and we quickly got to discussing how we could join forces to give me more time to focus with our product, engineering and design teams.
Chano will lead our GTM, operations and G&A teams and drive execution across Klaviyo; I will lead our product and engineering teams and drive our long-term vision; and together we will foster a culture of intensity, excellence and humility that’s been at our core since we started 13 years ago. From the many meals and whiteboard sessions we’ve shared, I have deep respect and admiration for Chano. Our skills are highly complementary and our values and commitment to excellence are deeply shared. As someone who grew up in Boston, where the bar for
academics and sports is elite, I was reminded of this just last week when in the heat of a discussion he told me, “I just want to win – our customers to win and for us to win.” I couldn’t agree more.
Chano, welcome aboard! Our best products and years are ahead. I couldn’t be more excited for Klaviyo, our customers and our partners.
As a physics major, it’s hard not to feel like Voyager reaching one light-day. What we’ve achieved is incredible, and yet not at all close to our ultimate ambition.
