Klaviyo Buys AI Startup Agency, Names Its Founder CPO to Supercharge Autonomous Commerce Tools
Key takeaways
- Klaviyo acquired Agency, founded in 2023, which had raised $32 million from Sequoia, Menlo Ventures, and Felicis.
- Agency founder Elias Torres joins Klaviyo as chief product officer, bringing his 25-person team with him.
- The deal targets growth for Klaviyo's AI agents — Composer and Customer Agent — across its 200,000-plus merchant base.
Klaviyo, the publicly traded e-commerce marketing automation platform, has agreed to acquire Agency, a three-year-old AI startup focused on customer success automation. Financial terms were not disclosed, but Agency had raised $32 million from prominent venture firms including Sequoia, Menlo Ventures, and Felicis before the deal closed. The 25-person Agency team will move under Klaviyo's roof as part of the transaction.
Elias Torres, who founded Agency in 2023, will join Klaviyo as its new chief product officer. In that role, he will lead efforts to expand Klaviyo's existing AI agent lineup, which currently consists of two products: Composer, a tool that builds marketing campaigns, and Customer Agent, which handles post-sale interactions like returns and order tracking. Klaviyo CEO Andrew Bialecki described the goal plainly — combine Agency's technology with Klaviyo's agent products and bring the result to 200,000 businesses, with ambitions to scale into the millions over the coming years.
The acquisition carries a notable personal dimension. Torres and Bialecki have a professional history stretching back to 2010, when Torres hired Bialecki as one of Performable's first engineers. Bialecki had graduated from Harvard just two years earlier and later credited Torres as a formative mentor during his early startup years. When Bialecki co-founded and bootstrapped Klaviyo after leaving Performable, Torres eventually became one of his angel investors in Klaviyo's 2015 seed round.
Torres himself is no stranger to large exits. He co-founded Performable, which HubSpot acquired in 2011, and later served as CTO at Drift for eight years through its $1.2 billion sale to Vista Equity Partners in 2021. Agency represented his most recent venture before this acquisition brings him back into direct partnership with Bialecki at a company he helped fund nearly a decade ago.
Klaviyo completed a high-profile IPO in September 2023 at a $9.2 billion valuation, though its stock has since declined alongside broader pressure on SaaS valuations. Both Bialecki and Torres contend that Klaviyo's years of accumulated customer data give its AI agents a competitive edge over pure-play rivals such as Decagon and Sierra. Bialecki framed the convergence as a defining industry moment, drawing a parallel to the early days of the cloud computing wave.
The bigger picture
The Klaviyo-Agency deal is worth watching beyond the headline numbers, primarily because it illustrates how well-capitalized SaaS incumbents are responding to the threat — and the opportunity — posed by autonomous AI agents. Rather than building entirely from scratch, Klaviyo is effectively acqui-hiring a focused team and a validated product at a stage when the AI agent market is still forming. That's a deliberate strategic posture, and one that rivals like Salesforce, HubSpot, and Attentive will need to react to as they build out their own agent layers.
The competitive framing here is direct. Bialecki specifically called out Decagon and Sierra as competitors whose agent products lack the depth of historical commerce data that Klaviyo holds across its merchant base. That data moat argument is central to Klaviyo's AI pitch — and if it holds, it becomes a meaningful barrier that pure AI-native startups will struggle to replicate quickly. Investors backing those startups should pay close attention to whether customers prioritize sophistication of data context over the agility of a purpose-built agent platform.
Finally, the Torres-Bialecki reunion signals something broader about how second and third-time founders are recirculating through the startup ecosystem. Torres has now been on multiple sides of a deal — founder, mentor, angel, acquiree — and that kind of network density tends to move fast and quietly. Readers should watch whether Agency's acquisition accelerates Klaviyo's product release cadence over the next two quarters, as that will be the clearest indicator of whether the deal's strategic logic translates into shipped features.
We flagged this story because it sits at a genuinely interesting intersection: a mature public company making a targeted AI acquisition while also reuniting a mentor-protégé pair who go back fifteen years. That kind of human thread doesn't usually accompany SaaS M&A coverage, and we thought it deserved proper context rather than a quick transaction note. At LagPing, we track how AI agent tooling is reshaping the software landscape for businesses of all sizes — Klaviyo serves over 200,000 merchants, which means changes to its platform ripple well beyond Silicon Valley. The fact that Torres is stepping into the CPO seat, rather than a softer advisory role, suggests Klaviyo is treating this as a capability acquisition, not a talent grab. We'll be keeping an eye on Composer and Customer Agent's roadmap over the next several months to see whether this deal produces meaningful acceleration.
