Klaviyo Expands K:Partners Program — Redefining How Tech Partners Build, Scale, and Grow in the AI Era

Klaviyo empowers creators to own their growth. We’re bringing that same commitment to technology partners. Today, we’re launching the K:Partners Technology Program, the most comprehensive expansion of our partner program. It builds on the availability of Klaviyo’s Model Context Protocol (MCP) Server, our recently launched App Marketplace, and expands our developer platform to give B2C brands a better way to discover, connect with, and grow through trusted integrations.

With the revamped K:Partners Technology Program, Klaviyo is meeting partners where they are: offering the tools, visibility, and support to launch integrations faster and deliver greater impact for shared customers. At its core, the K:Partners Technology Program reflects Klaviyo’s belief in an open platform that empowers developers to build integrations, agents and workflows directly connected to our intelligence layer.

Available now, this dedicated program gives exclusive access to Klaviyo resources and dedicated support for developers and product teams across apps, installs, and joint marketing campaigns for creating high-impact integrations.

  • A marketplace built for discovery. The redesigned App Marketplace helps the best integrations stand out. We’re connecting the right brands to the right apps—right when they need them. For partners, that means more visibility, higher install rates, and sustained growth. For customers, it means more powerful tools, easier access, and less time spent searching.
  • A true self-service partner portal. The Partner Portal is a command center for Klaviyo tech partners. It’s where partners can manage installs, track performance, access documentation, and engage directly with Klaviyo. As partners scale, they unlock even more benefits—from early API access to co-marketing opportunities and strategic collaboration with our teams. It’s not just a place to manage an integration—it’s a place to grow one.
  • A hub for going to market faster. The new Partner Demand Center gives partners everything they need to sell and deliver. From co-branded campaign templates to go-to-market toolkits and AI-powered enablement, the Demand Center helps partners amplify their reach and give value to customers from day one.

“Great customer experiences don’t happen in isolation, they’re built by ecosystems working together,” said Eddie O’Brien, SVP Global Partnerships & Alliances. “This program is about empowering our partners to deliver more value to the brands we both serve, faster and with greater impact. When our partners succeed in helping customers grow, everyone wins.”

“It’s not just about building an integration; it’s about building a partnership that scales. From the technical support to the visibility through the App Marketplace, every part of the program helped us move faster and deliver more value,” said Mike Rossi, CEO of Smile.io. “We saw real results – higher retention, more qualified leads, and stronger conversations with bigger brands. That kind of ecosystem support is rare, and it’s exciting to see Klaviyo formalizing it into a program that more partners can benefit from.”

The K:Partners Technology Program is now live. Partners can apply today to access exclusive tools, co-marketing support, and a marketplace reaching 183,000+ brands ready to grow. Visit https://www.klaviyo.com/partners/technology-partnerships to get started.
