The credits behind the numbers are free on purpose, and the quarter that carries them shows the bill: softer gross margin, thinner cash, another buyback. TechSignal, a buyer-side publication for marketing-technology purchases, has made the competitive read no rival will enjoy: [Klaviyo](https://theinference.org/markets/companies/klaviyo) is the first marketing-software vendor to publish usage numbers for an AI agent that a buyer can check [1]. Composer, its marketing agent, passed 10,000 daily active accounts in the three weeks after its October release [2]. Weekly usage more than tripled, to 18 million credits [2]. From now on, every vendor in this category gets evaluated on adoption data rather than feature lists, because one of them can produce it [1]. ## Usage changes what buyers can demand, and what vendors can charge What changes is what a buyer can ask for. Once usage is measurable, procurement can demand the number, and pricing attaches to measured agent usage, so customers pay for what the agent does rather than for seats. [HubSpot](https://theinference.org/markets/companies/hubspot), the larger seat-priced rival whose [shares are down roughly half this year](https://theinference.org/article/hubspot-brings-back-co-founder-brian-halligan-as-ceo-with-the-stock-down-nearly-half-in-2026), has started charging by outcome: $0.50 for a customer conversation its agent resolves on its own [3]. It also lets buyers swap seats for AI credits mid-contract, after cutting about 660 roles [3]. Klaviyo's Customer Agent, its support-side product, already bills per conversation the agent resolves itself [8]. ## The credits are free on purpose The proof of adoption is real, and so is its price to customers: nothing. On [the earnings call](https://finance.yahoo.com/markets/stocks/articles/klaviyo-kvyo-q3-2026-earnings-193120079.html), co-founder and co-chief executive [Andrew Bialecki](https://theinference.org/markets/people/andrew-bialecki) said Klaviyo is "deliberately giving customers free credits," and that the usage statistics it quotes are "not direct monetization" [2]. The revenue link so far is indirect: accounts that use Composer convert to paid plans at about 1.5 times the rate of those that do not [2]. Chief financial officer Erica Smith says agent revenue will be consumption-based, and that she is watching those trends through the fourth quarter [2]. The usage is measured; the money from it has not arrived yet. ## The quarter shows what the position costs Revenue was $387.2 million in the third quarter, up 25 percent [4]. The fourth-quarter guide implies about 21 percent, a step down [4], and extends the demand shift we traced [when Shopify missed and Affirm raised](https://theinference.org/article/shopify-missed-for-the-first-time-in-four-years-affirm-s-34-growth-and-klaviyo-s-raise-say-demand-moved) on November 6. Gross margin has been slipping for two years as text messaging, which carries carrier fees, takes a bigger share of the business, and management told investors to expect another seasonal dip this quarter [2]. *Chart: **Growth has slid to 24.6%, and the fourth-quarter guide implies about 21%** Column chart of Klaviyo's year-over-year revenue growth by quarter, from 35 percent in Q2 2024 down to 24.6 percent in Q3 2026, with a final column showing about 21 percent implied by the fourth-quarter guide.* *Year-over-year revenue growth, percent, fiscal quarters ended June 2024 through September 2026.

They are [up 65 percent from $12.86 in June](https://www.investing.com/news/investment-ideas/klaviyo-stock-surges-65-after-investingpro-fair-value-spotted-opportunity-93CH-5020977) [7], and [Goldman](https://theinference.org/markets/companies/goldman-sachs), which [pulled its Buy](https://theinference.org/article/klaviyo-made-its-ai-agent-free-to-every-customer-ten-days-later-goldman-pulled-its-buy) after Klaviyo made the agent free to every customer, is raising targets again [7]. ## The next report is where free credits get measured Klaviyo has done the part no rival has done: put a number on agent usage and let buyers check it [1]. Every marketing vendor should now be asked for the same figure, and a vendor that cannot produce one is selling a roadmap. The re-rating question is narrower than the run suggests: credits given away have to become credits paid for while gross margin holds, and the next earnings report is where that gets measured. ## Takeaway Klaviyo is the first marketing vendor to put a checkable number on agent adoption, but the credits behind it are free and the quarter shows the bill: softer gross margin, cash down $360 million from its peak, and another buyback. ## Sources 1.
