Klaviyo x Vibe.co: Turning customer data into measurable TV. Klaviyo and Vibe now connect directly, so B2C brands can push their Klaviyo audiences into Vibe, run acquisition and suppression on premium CTV, and measure the result in the same tools they already trust. It's the missing link between the data that powers every other channel and the one screen it never reached. Boston Proper put it to work first and drove 3.25x ROAS on 8M+ impressions. Why this integration matters. Performance marketers hold every channel to the same standard: built on real customer data, judged on measured outcomes. CTV has been the exception - not for any lack of reach or impact, but because the customer data that powers precise campaigns everywhere else rarely reached the TV screen, and the results rarely made it back into the tools marketers use to judge spend. Klaviyo sits on exactly that data. Klaviyo's autonomous B2C CRM captures what customers do online and offline so brands can personalize how they reach them. The Vibe integration takes that intelligence and puts it to work on CTV, then closes the loop on measurement. How it works. Brands connect Klaviyo to Vibe and use their CRM audiences to: * Acquire. Reach net-new prospects by layering Klaviyo audience data over Vibe's premium inventory. * Suppress. Apply suppression lists to keep existing customers out of acquisition spend, so budget goes to incremental reach. * Measure. Tie CTV exposure back to attributable outcomes through Vibe's native measurement integrations, including Northbeam. Because Vibe is self-serve, brands set this up themselves. No managed-service middle layer, no new reporting infrastructure, no waiting on an insertion order. Boston Proper: the proof. Boston Proper, a women's fashion brand with a loyal base and an aggressive net-new acquisition goal, runs Klaviyo for CRM and email, and Northbeam for attribution. Both had to integrate cleanly with any CTV partner, and Vibe connected to both without friction. The team built separate acquisition and retention programs, layered Klaviyo's CRM data onto Vibe's premium inventory to find the right new customers, and used suppression lists to protect their existing base. The result: 3.25x ROAS measured by Northbeam's deterministic view-through attribution, 8M+ impressions, and a year-over-year lift in new prospect audiences. Part of a measurable-by-default stack. Klaviyo joins Northbeam, Triple Whale, and Prescient in a growing set of data and measurement integrations that make CTV on Vibe accountable to revenue, not impressions. Bring the audiences you already own and the measurement you already trust; Vibe puts them on the big screen and reads the results back. Already run Klaviyo? Connect it to Vibe and turn your CRM audiences into measurable TV. Jul 29, 2026 Last updated: Aug 03, 2026

How Vibe's growth team launched 250 personalized campaigns in less than 15 minutes. First in the Vibe for Vibe series, tied to the Vibe AI product suite. Every growth team runs into the same tradeoff. Personalize a campaign for each account, and setup time multiplies with every account you add. Automate to save time, and the personalization disappears. Vibe's team had faced this challenge, until Vibe, Inc. launched the full suite of Vibe Public APIs. Vibe's VP of Growth & Marketing, Romain Marsal, leveraged the API to launch 250 personalized ABM campaigns - one per target account, in a matter of minutes. What 250 personalized campaigns entailed before. Romain leads growth marketing at Vibe. The team works across every platform a performance marketer touches. Before AI entered the workflow, that meant one specialist mastering the configuration quirks of each one: launch a campaign, check performance, tweak the audience, iterate on creative, then do it again for the next platform. That became a real bottleneck when Romain's team set out to run true account-based marketing: a dedicated CTV campaign for each of 250 target accounts, each with its own matched audience and matched creative. Configured manually, a campaign like this takes roughly 10 to 30 minutes: targeting, audience, creative assignment, review. Multiply that across 250 accounts and you get 40-125 hours of manual setup before a single impression airs. Per Demand Gen Report's 2026 ABM Benchmark Survey, marketers now rank personalization at scale as AI's single biggest impact on ABM, ahead of targeting or content creation. Romain's team ran into that exact wall. How the Vibe API turned 125 hours into 15 minutes. The old way of working meant a campaign this personalized either wasn't possible, or it was too costly to justify. Romain tested a different approach. He opened Claude, dropped in his list of 250 target accounts from Clay, and manually briefed the LLM on one of the campaigns. Once he saw Claude got it right, he let the Vibe API take it from there. How did he do it? * He started with a list of 250 target accounts and used Clay to enrich account data per company. * That data fed into the API, which built a dedicated campaign per account: one audience, one budget, one set of targeting parameters, all matched to the specific business. * Vibe's agency had delivered the 250 creatives in a spreadsheet, one per account. * The API read the spreadsheet and matched each creative to its campaign automatically, with a 98% match rate on the first pass. The campaign builder was never opened. No one manually uploaded or matched anything. The entire workflow ran out of a single chat interface. What this means for you (if you're not running Vibe's growth team). Romain's team didn't need to hire more people to pull off their dream ABM scenario. They used capabilities that are available to any advertiser on the platform today. * Full API and MCP coverage: everything available in the Vibe UI is also available to automate. You don't have to click through campaign setup, targeting, or creative assignment one screen at a time. * Vibe fits inside the tools you already use: the API and MCP plug into whatever your team already runs on, spreadsheets, CRMs, enrichment tools, so campaigns get built from data you already have, not a new system you have to learn. * No engineering team required: MCP wraps that same API power as a chat interface. If your team isn't writing code, you get the same speed and scale without a developer handoff. If you're running one campaign at a time today, this is how you get to ten, or two hundred fifty, without hiring to match. Why this matters. The heaviest lifting, enriching and fetching data on hundreds of employees, ran unattended in the background for about 8 hours while Romain and his team worked on something else entirely. Romain explains, "It took time, but it wasn't my time. I could work on other things while it ran in the background." And running hands-off didn't cost accuracy: the campaigns still matched creative to account at a 98% rate. That time went to the agency brief: sharpening the creative, deciding how each account should be positioned, thinking through strategy instead of mechanics. That's the shift. Not less work, different work. The team's time moved from clicking through configuration screens to the creative and strategy that actually moved performance. Marketers get to focus on marketing.

Walmart buys Vibe, an adtech launched by two Frenchmen. This acquisition is a lever for Walmart to accelerate its development in retail media. It is also a great deal for the French founders and investors like Elaia and Singular. Prestigious exit for Vibe. The company, behind a video streaming advertising platform, is about to be acquired by Walmart, the American retail giant. The terms of the operation have not been disclosed, but it should be finalized by the end of fiscal year 2027. Once the transaction is concluded, Arthur Querou, co-founder and CEO of Vibe, and Franck Tetzlaff, co-founder and CTO, as well as the entire Vibe team, will join Walmart Connect, the retail media division of the American group. For Walmart, this acquisition represents a lever to accelerate its development in retail media. The American giant sees it as an opportunity to boost its commercial audiences in the TV advertising market. "Vibe has created a platform specially designed to simplify streaming TV advertising. Together, we will be able to help more businesses connect with their customers in streaming environments while measuring the impact of these campaigns thanks to Walmart's commercial capabilities," says Ryan Mayward, general manager and senior vice president of Walmart Connect in the United States. If Walmart is so interested in this market, it's because of its thriving potential. And for good reason, streaming now accounts for 45% of TV audience in the US, surpassing the combined share of cable and traditional television. In this context, digital video advertising spending, including connected TV, is growing nearly three times faster than the overall advertising market. "This next-generation TV advertising market should surpass that of social media by 2035, thanks to the massive arrival of direct-to-consumer brands and Instagram advertisers," Arthur Querou had even predicted last year. An acquisition 6 months after the Series B. Last October, Vibe closed a $50 million Series B led by the discreet British fund Hedosophia (Spotify, Uber, Airbnb, Qonto...). Also present were Elaia and Singular, which are achieving a nice exit with the acquisition of the company by Walmart. It took five years for Franck Tetzlaff, one of the founders of Doctolib and former CTO of Frichti, and Arthur Querou, founder of Appinest and MotionLead before becoming Chief Mobile Officer of the French adtech Adikteev, to achieve this deal. Another exit for the two entrepreneurs, who had already sold an adtech (KMTX, semantic targeting specialist) to Seedtag in 2022. Vibe's acquisition by Walmart comes as the adtech records $227 million in annual recurring revenue (ARR), compared to $100 million last year and $46 million in 2024. A few months ago, the company hoped to cross the $1 billion revenue mark by 2028. An ambition that is likely to accelerate considerably now that the company is about to join the fold of the world's largest retail group, which generates more than $700 billion in revenue.
