The Market Stopped Paying for Growth
Two of the platforms your customers run reported earnings this month. Both beat. Both got sold off. The repricing is the story, and it is coming for the budgets underneath you.
Last month the majors all bought the same thing: the governed data layer underneath the stack. This month the market told them what it now expects in return.
Zeta and Klaviyo both reported strong quarters. Both beat revenue. Both raised guidance. Both stocks fell anyway. Growth alone stopped clearing the bar. The market has started pricing whether the growth is efficient and durable, not just fast. That is the same question every CFO is about to put to every marketing budget, and one of these two companies handed everyone the answer key in its own numbers.
The Market Repriced Growth in One Week
August 4 · Q2 earnings
Zeta beat, raised, and slipped anyway
Revenue of $443M, up 44%, beating consensus and marking the 20th straight beat-and-raise quarter. Adjusted EBITDA up 56% to $92M. GAAP net income turned positive. Free cash flow up 73%. Guidance raised again. And the stock still fell. The reasons matter: the size of the beat has narrowed from 7% to under 3% over recent quarters, organic growth stripped of acquisitions runs 22 to 23% against the 44% headline, and heavy stock comp keeps GAAP margins thin. A genuinely good quarter was not good enough.
August 5 · Q2 earnings
Klaviyo did the same thing and fell harder
Revenue of $370.6M, up 26%, a beat, with full-year guidance raised to roughly $1.53B. Free cash flow margin above 22%. Shares dropped more than 11% after hours. The cause was on the margin line, not the top line: gross margin compressed to 73.4% under SMS carrier fees, and Klaviyo cut its full-year operating-income outlook to fund the Agency acquisition and more product build. Same pattern as Zeta. A revenue beat, sold off on profitability.
The Proof Was in the Adoption Data
Inside the Zeta print
The customers who actually adopted are carrying the business
Zeta broke its base out by depth of AI adoption, and the split is the most useful number in the month. The customers who fully adopted Athena are 20% of the base and drive roughly 70 to 75% of revenue. They grew four times faster than everyone else. They retain 400 basis points better than the company average. Same platform. Same features available to all. The entire gap is who activated and who just bought. Voice tells the same story: 83% of Athena interactions are now spoken, and those users engage at five times the rate of non-adopters.
The backdrop
The measurement drumbeat kept going
A MarTech piece late last month put it plainly: AI is speeding up production, and most teams are still measuring clicks instead of business outcomes. It lands next to the Comviva finding that 90% of companies raised AI marketing spend and 12% can prove it worked. The public market spent this month pricing that exact gap into two vendors at once. The survey version and the stock-market version are now the same story.
“Marketing is the first application, not the limit.”
— David Steinberg, CEO, Zeta Global · Q2 2026 earnings call
What This Means for Your Installed Base
The public market just did to Zeta and Klaviyo what your customers’ finance teams are about to do to their marketing budgets. It stopped paying for activity and started asking what the spend returned.
Zeta handed you the mechanism in its own deck. The customers who adopted deeply retain 400 basis points better and drive most of the revenue. The ones who bought and stalled do not. The difference is not the platform. It is activation. Every base has this same split running through it right now.
So look at your own book the way the market just looked at theirs. The accounts most at risk are not the loud, unhappy ones. They are the quiet ones who signed, never activated, and have no evidence the spend ever worked. When their CFO asks what marketing returned this year, “we shipped more campaigns” is the answer that loses the renewal.
The month proved the point at the ticker level: growth without proof of efficiency gets repriced. It is true for a public company and it is true for a line item inside one of your accounts.
The renewal is not won on a roadmap deck. It is won on proof the spend already worked. Independent, measured, on the stack they already own.
