Autonomous B2C CRM platform Klaviyo has reached a definitive agreement to acquire the team and technology of Agency, an AI-native customer success company led by serial entrepreneur Elias Torres. Following the transaction’s expected close in Q3 2026, Torres will join Klaviyo as Chief Product Officer (CPO). Reporting to co-CEO Andrew Bialecki, Torres will lead Klaviyo’s agent product line, including Composer (its autonomous marketing campaign agent) and Customer Agent
The transaction brings Agency’s proprietary artificial intelligence software, intellectual property, and engineering team directly into Klaviyo’s underlying B2C data infrastructure. By pairing Agency’s agentic systems with Klaviyo’s consumer dataset which stores more than nine billion consumer profiles and processes over 250 billion quarterly data points the acquisition accelerates the delivery of fully autonomous marketing and customer engagement capabilities for more than 205,000 paying business clients.
“Elias and I have always believed every customer should be treated like they’re the only one. Agents give us a powerful new way to deliver on that belief,” stated Andrew Bialecki, co-founder and co-CEO of Klaviyo. “At Klaviyo, we’ve spent years building the data and infrastructure needed to create deeply personalized customer experiences, and Composer and Customer Agent demonstrate what that foundation can enable.”
“By joining Klaviyo, I get the other half—an understanding of consumer behavior that nobody else has, and the ability to scale faster,” added Elias Torres. “Working with Andrew and the Klaviyo team, I get to push that further and change how millions of consumers experience the businesses they buy from.”

Unifying Marketing and Service Workflows
Traditional marketing automation systems relied on static rules, manual audience segmentation, and rigid email drip campaigns. When customer inquiries or unexpected behaviors occurred outside pre-programmed paths, systems struggled to adapt without human intervention.
Integrating Agency’s agentic framework with Klaviyo’s real-time data engine addresses these limitations across two coordinated agent workflows:
Growth and Campaign Orchestration (Composer): Functions as a proactive marketing agent that analyzes performance signals, identifies underperforming sequences, builds multi-channel campaigns, and optimizes messaging across channels in real time.
Real-Time Customer Engagement (Customer Agent): Operates as an always-on conversational interface capable of handling post-sale service inquiries, processing returns, and recommending products, while writing intent signals back to the central customer profile.
Shared Context Infrastructure: Both agents operate off the same real-time customer data graph, ensuring every service interaction enriches future marketing campaigns and vice versa.
Strategic Effect on the Marketing Sector.
Integrating customer support and execution marketing within one autonomous CRM creates a new operating playbook, radically changing the way a CMO or B2C brand executive manage the following3:
1. The Elimination of Disconnected Functional Silos
In the past, marketing and servicing happened in separate tools. A buyer who received an item in the mail 2 weeks late, or wanted to return it, could simultaneously receive a relevant promotional sales pitch and thereby alienate that customer.
Combining marketing agents and service agents together on the same platform ensures that promotional messaging and servicing can be synchronized in real time and not run afoul of each other, leading to more trust down the line.
2. Shift from Manual Campaign Construction to Strategic Direction
Now marketers devote valuable time to designing sophisticated logic trees, defining conditional A/B tests, and preparing all their contact lists for each step of the sales process. Agentic AI replaces the manual task-oriented role of the marketer with one of strategic direction and control.Rather than dragging and dropping each component, teams define their desired growth targets, with the AI agent designing, testing, and launching campaigns in response to real time data. Without the Brand Voice and Historical Customer Context, generic AI tools will simply generate generic uninspiring Content.
3. Hyper-Personalization Grounded in First-Party Data
Directly tying autonomous Agents to a deep, first-party data infrastructure allows for consumer brands to serve up 1-to-1 dynamic messaging at scale across millions of buyers without adding headcount or violating privacy standards.
Broader Effects on Businesses Operating in the MarTech Sector
The introduction of agentic AI into large-scale B2C platforms generates broad competitive shifts within the economic system:
Obsolescence of standalone point tools: Single-purpose email add-ons, static rule-based chatbots, and standalone ticketing systems will churn faster and faster as more merchants move to integrated platforms that merge marketing, service and deep customer data context.
Faster First-Party Data: Revenue for E-Commerce brands that have built large first-party datasets of users can begin monetizing those assets immediately through deploying AI Agents that can read buying intent and enact conversion models.
Higher Operating Margin : Automating routine marketing audits and service resolutions consumed away admin expenses through directly boosting the net operating margins and customer lifetime value (LTV) for digital retailers.
Conclusion
Klaviyo acquiring Agency is an inevitable step forward into a very high degree of autonomous customer relationships. Integrating data about people and automating outreach, through conversing AI agents, is the kind of seamless user-experience that is so crucial for mass adoption.Forthcoming AI execution will be judged in that domain on its ability to adapt dynamically and perpetually.
Those companies and brands that transition to an autonomous marketing engine will cluster to the upper-right of the adoption S-curve and will accrue long-term higher retention, campaign agility and revenue growth while brands that rely on the legacy market tools and patchwork of tactic-focused systems will gravitate toward the stagnant lower-left.
