What Happened: Klaviyo Buys Agency
Klaviyo, the publicly traded e-commerce marketing automation company, has agreed to acquire Agency, a three-year-old startup built around AI-powered customer success tools. Agency was founded in 2023 by Elias Torres, a repeat founder well known in Boston and SaaS circles, and had raised $32 million from a strong roster of backers, including Sequoia, Menlo Ventures, and Felicis, before this acquisition. Financial terms of the transaction have not been made public.
Under the terms of the deal, Torres steps into the role of Chief Product Officer at Klaviyo. He’ll bring Agency’s 25-person team with him, and their mandate is clear: speed up development of Klaviyo’s growing suite of AI agents, specifically Composer, which builds marketing campaigns, and Customer Agent, which manages post-sale support tasks such as returns and order tracking.
This is being described inside the industry as an acqui-hire with strategic depth , not just a talent grab, but a combination of a working AI customer-success product with Klaviyo’s existing agent stack and its massive base of e-commerce customer data.
Why This Deal Matters for the AI Agent Race
The acquisition lands at a moment when nearly every major CRM, marketing, and customer service platform is racing to ship autonomous AI agents. Klaviyo has been especially aggressive on this front throughout 2026, rolling out and expanding two flagship agents:
- Composer , an AI marketing agent that turns a single prompt into a launch-ready campaign, including audience segmentation and cross-channel messaging.
- Customer Agent , an AI-powered service platform that resolves customer support interactions such as returns, exchanges, subscription changes, and order tracking, and can act autonomously (completing a return, not just explaining the policy).
Klaviyo introduced Composer as a new agentic experience in March 2026, then moved it into public beta at the end of June 2026 alongside major upgrades to Customer Agent. The company’s pitch to the market has centered on the idea that generic AI tools produce generic results because they lack a brand’s own voice, purchase history, and behavioral signals , while Klaviyo’s agents are trained on real-time customer data that both agents share across marketing and service functions. When Customer Agent resolves a support conversation, that interaction feeds back into the customer profile that Composer then uses to build sharper campaigns, and vice versa , a flywheel Klaviyo argues gets smarter with every interaction.
Bringing in Torres and Agency’s team accelerates that roadmap by adding a founder who has already built and shipped a dedicated AI customer-success product, plus 25 engineers and product people who understand the problem space deeply. For Klaviyo’s CEO Andrew Bialecki, the goal is scale: bringing the combined agent capabilities to roughly 200,000 businesses currently on Klaviyo’s platform, and eventually to millions more.

Who Is Elias Torres? A Founder Who Keeps Coming Back
Elias Torres is not a first-time founder testing the waters , he’s a serial entrepreneur with a long track record of building and selling companies, almost always in the sales, marketing, and customer engagement space.
Performable and the HubSpot Acquisition
Torres co-founded Performable, an early marketing analytics and automation company. Performable was acquired by HubSpot in 2011, an early proof point for Torres as a startup operator who could build something valuable enough for a much larger company to buy.
It was at Performable, back in 2010, that Torres hired a young engineer named Andrew Bialecki , a recent Harvard graduate , as one of the startup’s first hires. Torres mentored Bialecki during that period, teaching him how early-stage startups actually operate day to day. Torres has since said Bialecki absorbed those lessons quickly.
Drift: An Eight-Year Run to a $1.2 Billion Exit
After Performable, Torres co-founded Drift, the conversational marketing and sales platform, where he served as Chief Technology Officer for eight years. Drift became one of the more recognizable names in B2B SaaS during the 2010s, pioneering chat-based lead generation for websites. In 2021, Vista Equity Partners took a majority stake in Drift, a deal that valued the company at $1.2 billion and pushed it into unicorn status.
Agency: Betting on AI for Customer Success
In 2023, Torres launched Agency, aiming to bring AI automation to customer success management , essentially building an AI layer that could help customer success teams do more with less, at a moment when AI copilots and autonomous agents were becoming the dominant theme in enterprise software. The startup attracted top-tier venture backing, including from Sequoia, Menlo Ventures, and Felicis, and grew to a 25-person team before this acquisition.
Who Is Andrew Bialecki, and Why the “Full Circle” Framing?
Andrew Bialecki co-founded Klaviyo shortly after leaving Performable, initially bootstrapping the company rather than raising venture money right away. When Klaviyo did raise its first outside capital in 2015, Bialecki brought the relationship back around , inviting Torres, his former boss and mentor, to participate as an angel investor in that seed round.
Klaviyo went on to become one of the most closely watched e-commerce infrastructure companies of its generation, completing a high-profile initial public offering in September 2023 at a $9.2 billion valuation. Now, more than a decade after Torres first hired Bialecki as an engineer, and roughly a decade after Bialecki invited Torres to invest in Klaviyo’s earliest round, the two are working together directly again , this time with Torres reporting into the company Bialecki built, in a formal product leadership role.
Bialecki has publicly framed the reunion as picking up where the two left off at the start of the cloud software era, this time applied to what he sees as the next major shift in enterprise technology: autonomous AI agents.
Klaviyo’s Competitive Position in AI Customer Service
Klaviyo’s stock, like many SaaS companies, has faced pressure in the broader public market environment of 2026. But Bialecki and Torres are betting that Klaviyo’s structural advantage , years of accumulated, real-time customer data from its e-commerce customer base , gives its AI agents an edge that newer, data-light AI customer service startups can’t easily replicate.
That’s a direct reference to the competitive landscape Klaviyo is playing in, which includes well-funded AI customer service startups such as:
- Decagon , an AI customer service agent platform serving enterprise brands.
- Sierra , an AI agent platform co-founded by Bret Taylor, focused on building conversational AI agents for large consumer brands.
Both companies have raised significant venture funding and positioned themselves as go-to platforms for enterprises building AI-powered customer experiences. Klaviyo’s argument is that being embedded directly inside a CRM that already holds a brand’s marketing, purchase, and behavioral data gives its agents richer context than a bolt-on AI layer sitting outside that data pipeline.
The Bigger Trend: Acqui-Hires Are Reshaping the AI Agent Market
This deal is part of a broader pattern playing out across enterprise software in 2026: rather than building every AI capability from scratch, or purely competing for market share, larger platforms are acquiring smaller AI-native startups , often specifically to bring in founding teams with deep product expertise in a narrow but strategically important area.
Klaviyo’s move to absorb Agency mirrors a wave of similar consolidation happening across the industry, where platform companies see faster time-to-market in buying a working product and its team rather than building competing functionality organically. For founders like Torres, it also represents a well-worn path: build a focused product, prove it works, and let a larger platform with distribution acquire it rather than trying to out-scale much bigger incumbents independently.
For Klaviyo specifically, the acquisition also signals confidence that customer success and customer service are not separate problems from marketing , they’re two sides of the same customer relationship, and increasingly, both are being run by AI agents drawing from the same underlying data.
What This Means for Businesses Using Klaviyo
For the roughly 200,000 businesses currently on Klaviyo’s platform, this acquisition is likely to translate into faster development of AI agent capabilities across both marketing and customer service. Practically, that could mean:
- Faster feature velocity for Customer Agent , with an experienced AI customer-success team now embedded inside Klaviyo, expect quicker rollout of new automated service capabilities (returns, subscriptions, order tracking, and beyond).
- Tighter integration between marketing and service AI , Torres’ product leadership is explicitly tied to accelerating how Composer and Customer Agent share data and intelligence with each other.
- A stronger competitive pitch against dedicated AI customer service vendors , brands evaluating standalone tools like Decagon or Sierra now have a more compelling “all-in-one” argument from Klaviyo, especially if they’re already running marketing through the platform.
- Product leadership continuity risk to watch , as with any acqui-hire, the real test will be how well Agency’s technology and team integrate into Klaviyo’s existing roadmap and culture over the next 12–24 months.
