Klaviyo just made an acquisition that doubles as a reunion. The publicly traded e-commerce marketing platform has agreed to buy Agency, a three-year-old AI customer success startup founded by serial entrepreneur Elias Torres, according to TechCrunch AI. Terms weren’t disclosed, but the story behind the deal is what makes it worth your attention.
Agency launched in 2023 and raised $32 million from Sequoia, Menlo Ventures, and Felicis before the sale. As part of the deal, Torres joins Klaviyo as chief product officer and brings his 25-person team with him. Their job: speed up Klaviyo’s push into AI agents.
What Klaviyo is buying
Torres and his team will lead development on two AI agents Klaviyo already runs:
- Composer, which builds marketing campaigns.
- Customer Agent, which handles post-sale support like returns and order tracking.
CEO Andrew Bialecki told TechCrunch AI the plan is to fold Agency’s product into these agents and roll it out wide. “We’re going to take that and combine it with our agent products and try to bring that to 200,000 businesses, and hopefully to millions more over the next couple of years,” he said.
That’s the real prize here. Klaviyo isn’t buying a product so much as buying the team and the expertise to move faster on agents, the category everyone in SaaS is racing toward right now.
The full-circle part
Here’s what stands out. Torres knows exits. He co-founded Performable (bought by HubSpot in 2011) and later Drift, where he was CTO for eight years until Vista Equity bought it for $1.2 billion in 2021.
Back in 2010 at Performable, Torres hired a recent Harvard grad named Andrew Bialecki as one of his first engineers, and mentored him on how early-stage startups actually work. “He soaked it up in a short amount of time,” Torres recalled to TechCrunch AI.
Bialecki left, bootstrapped Klaviyo, and when he raised his first outside money in 2015, he invited Torres to back the seed round as an angel. Klaviyo went public in September 2023 at a $9.2 billion valuation. Now the mentor reports to the former mentee. That’s a rare arc in tech, and it’s the emotional core of why this deal happened.
Why it matters for the AI industry
This is a signal about where marketing software is heading. The bet isn’t on better email templates. It’s on autonomous agents that run campaigns and handle customer service with limited human input.
Klaviyo’s argument for why it can win comes down to data. Torres and Bialecki believe the platform’s years of customer data give its agents an edge over well-funded rivals like Decagon and Sierra. That’s a reasonable claim. Agents are only as good as the context they operate in, and Klaviyo sits on a deep pool of e-commerce behavior data that a standalone agent startup would struggle to match.
It also fits a broader pattern worth watching: incumbents with proprietary data buying AI-native teams instead of building agent expertise from scratch. Klaviyo’s stock has taken a hit alongside other SaaS names, and moves like this are how established players try to reframe the story from “legacy software” to “agent platform.”
What to expect next
For the roughly 200,000 businesses on Klaviyo, expect the agent features to get more capable over the coming quarters as the two products merge. For the rest of the industry, this is another data point that the consolidation phase of the agent race has started. Talent and specialized teams are getting absorbed by platforms that already own the customer relationship.
Bialecki summed up the mood plainly: “It’s the next Big Tech revolution: agents. Let’s get the band back together, and let’s go build.”
Whether Klaviyo’s data advantage holds up against Decagon, Sierra, and the next wave of agent startups is the open question. But the reunion angle aside, this deal tells you exactly where a public marketing platform thinks the growth is. You can find the full details at the original source.
