The story

The company was founded in 2013 by Andrew Bialecki and Ed Hallen. Both Bialecki and Hallen had previously worked at Applied Predictive Technologies.

In August 2022, e-commerce company Shopify announced it was making Klaviyo the recommended email solution partner for its Shopify Plus merchant platform, with a US$100,000,000 strategic investment into the company.

In November 2022, Klaviyo announced its first acquisition, code development firm Napkin.io.

In April 2023, Klaviyo filed for an initial public offering (IPO) for a listing at the New York Stock Exchange. In September, the company went public, raising $576 million in the IPO at a $9.2 billion valuation.

In June 2023, Klaviyo partnered with e-commerce platform Prestashop with the launch of Prestashop Automation with Klaviyo

In 2023, Klaviyo first introduced AI-powered features, which as of 2025 include Marketing Agent, which automates campaign planning and optimization, and Customer Agent, which provides 24/7 customer service automation. The launches reflected the company's expansion from a marketing automation platform toward an AI-powered B2C CRM platform integrating customer data, automation, and omnichannel engagement.

In 2024, the Klaviyo Marketing Platform was localised into six non-English languages, French, German, Spanish, Italian, Korean and Brazilian Portuguese. In 2025 the platform was further localised into Dutch, Polish, Mexican Spanish and Swedish.

In August 2025, Klaviyo announced it had acquired Gatsby, a customer engagement platform. The acquisition expands the Klaviyo platform's capabilities to include social media marketing.
