Elias Torres Reunites with Klaviyo Founder in Agency Acquisition, Closing a 16-Year Mentorship Loop

Klaviyo, a publicly listed marketing automation vendor for online retailers, has acquired Agency, a three-year-old startup specializing in AI-powered customer support. According to TechCrunch, Agency’s founder—Elias Torres, an entrepreneur who has exited two previous ventures—will assume the role of chief product officer, overseeing the company’s 25-person cohort. Deal valuation was not made public.

Torres’s Second Encounter with Bialecki

The acquisition marks an unlikely reunion. In 2010, at the early-stage commerce startup Performable, Torres brought on Andrew Bialecki, then fresh from Harvard, as one of his first engineering hires. Torres mentored the younger entrepreneur on scaling and navigating startup challenges. Bialecki later departed and went on to establish Klaviyo, which he initially self-funded. When Klaviyo sought outside capital in 2015, Bialecki turned to Torres, who backed the seed round as an early investor. Klaviyo subsequently completed its initial public offering in September 2023 at a $9.2 billion post-money valuation.

Torres brings a track record of high-exit outcomes. Performable was acquired by HubSpot in 2011. He later co-founded Drift, a conversational sales platform where he served as chief technology officer for eight years until its 2021 acquisition by Vista Equity Partners at a reported $1.2 billion valuation.

Scaling Agent Infrastructure Across Commerce

Agency secured $32 million in prior funding from Sequoia, Menlo Ventures, and Felicis. The startup has built tools that automate customer interactions—specifically fulfillment assistance like return processing and shipment status. Klaviyo intends to consolidate Agency’s technical capabilities with its existing agent suite: Composer, an agent that generates marketing campaigns autonomously, and Customer Agent, which handles post-purchase support workflows.

According to TechCrunch, Bialecki told the publication the combined platform aims to serve 200,000 businesses initially, with expansion to millions over the next two years. Both founders view agent-based tooling as the next major shift in enterprise software, positioning Klaviyo against competitors like Sierra and Decagon in the emerging AI-agent-for-commerce segment.

Why This Matters

This deal signals two trends: first, that venture-backed AI agents for specific domains (here, e-commerce customer success) remain acquisition targets for larger platforms seeking distribution and technical depth. Second, it underscores how founder-investor relationships forged in one era—cloud infrastructure, 2010—are recycling into the next—agentic AI, 2026. For Klaviyo investors, the bet is that combining a large, established customer base with newly acquired agent-building talent can accelerate time-to-market against specialized competitors. For Torres, it represents a return to an ecosystem and partnership that seeded his prior exits, now at stakes orders of magnitude larger.
