Is Klaviyo Poaching Attentive’s Top Sales Team Amid SMS War?

The turf war between Klaviyo and Attentive has always been polite in public — competing roadmap announcements, carefully worded press releases, the occasional jab on LinkedIn. But behind the scenes in Q2 2026, something uglier is allegedly unfolding. Multiple sources close to the matter say Klaviyo has been running a sustained, coordinated effort to recruit senior account executives and customer success managers directly out of Attentive’s enterprise sales team — and that the effort is personal enough to have rattled Attentive’s internal culture.

“It’s not random LinkedIn outreach,” said one person with direct knowledge of the situation, who requested anonymity. “They’re targeting specific people who hold the largest book of business on the Attentive enterprise side. People managing $2M-plus in ARR accounts.” Klaviyo declined to comment on specific hiring activity. Attentive did not respond to requests for comment by press time.

How Deep Does the Recruiting Run?

According to two sources independently familiar with the matter, the alleged poaching campaign accelerated after Klaviyo’s Q1 2026 earnings call, where CEO Andrew Bialecki publicly flagged SMS as the company’s fastest-growing revenue segment — up reportedly 61% year-over-year. That signal, sources say, prompted Klaviyo’s people team to identify high-performing Attentive reps managing DTC accounts in the $10M-$100M GMV range, a segment both platforms consider their core growth battleground.

Unconfirmed reports circulating among agency leaders suggest at least six Attentive enterprise AEs have been approached with offers ranging from 20% to 35% above their current on-target earnings, plus accelerated equity vesting. At least two are reportedly in final-stage conversations as of mid-June 2026.

“When your competitor starts knowing the names of your top performers before your own VP of Sales does, that’s a signal. That’s not coincidence — that’s a program.” — Agency founder who works with both platforms, speaking anonymously

Is Attentive’s Enterprise Growth Actually Slowing?

The timing matters. Several agency sources tell Ecommerce Times that Attentive has quietly struggled to convert enterprise-tier trials in the first half of 2026, particularly among Shopify merchants who are already deep in the Klaviyo ecosystem. The pitch for a standalone SMS platform gets harder when Klaviyo’s unified email-SMS interface has closed much of the feature gap that defined Attentive’s differentiation two years ago.

Attentive’s reportedly strong play has been its AI-powered Concierge SMS product, which sources say showed strong early traction with beauty and apparel DTC brands in Q1. But the product requires a minimum 90-day onboarding ramp, and at least three agency operators told Ecommerce Times their clients paused or deferred adoption after Klaviyo demoed a comparable conversational SMS feature — reportedly codenamed “Signal” internally — at a private partner briefing in Austin in April 2026.

• Attentive’s Concierge SMS reportedly requires a minimum 3-month onboarding commitment before full AI personalization activates
• Klaviyo’s alleged “Signal” feature was demoed to select agency partners but has not been publicly announced as of June 23, 2026
• Both platforms are competing for the same DTC sweet spot: brands doing $15M-$80M in annual revenue with high repeat-purchase rates
• Agency margins on SMS platform implementations typically run 12-18% of first-year platform fees, giving agencies a financial stake in which platform wins

What Do Agency Partners Say About the Platform Drama?

Several agency leaders who manage SMS programs for DTC clients say the interpersonal friction is already showing up in sales cycles. One growth agency CEO — who manages SMS programs for 40-plus Shopify merchants — described receiving what she called “unusually aggressive” outreach from a Klaviyo sales rep who had apparently been briefed on specific Attentive clients her agency manages.

“They knew our client’s name, their approximate list size, and the fact that they were up for renewal in July. That level of detail doesn’t come from LinkedIn stalking. Someone talked.” — Growth agency CEO, identity withheld

Whether that intelligence came from a departing Attentive employee, a shared agency contact, or another source is unconfirmed. But the episode illustrates how competitive intelligence is flowing at the ground level of the SMS market — and how both companies are using partner networks as proxies in a war neither wants to fight openly.

On the Attentive side, sources say CEO Brian Long has been personally involved in retention conversations with at least two high-value sales leaders, and that the company has fast-tracked a compensation review for enterprise AEs that was reportedly not scheduled until Q4. Long has been publicly visible at industry events this spring — appearing at Shoptalk and a Klaviyo-adjacent agency dinner in New York where, sources say, his presence was interpreted as a deliberate show of stability.

Is There a Bigger Strategic Play Behind the Hiring Push?

Several observers believe the alleged recruiting campaign is less about filling headcount and more about intelligence gathering — specifically, gaining visibility into Attentive’s enterprise pipeline, pricing architecture, and renewal cadence before a potential consolidation event. Klaviyo’s stock has recovered meaningfully from its 2025 lows, and the company has publicly stated it is evaluating M&A opportunities in the “retention and lifecycle” category.

Acquiring Attentive outright has been speculated in startup circles since at least late 2024, when Attentive’s last reported valuation — $9.5 billion at its 2021 peak — became increasingly difficult to defend against a slower SMS adoption curve and tighter venture markets. Sources close to Attentive’s board say the company has rebuffed acquisition conversations more than once, but that internal pressure to find a liquidity path is real.

“If you’re thinking about buying a company, the fastest due diligence is hiring their best people and asking them what the pipeline actually looks like.” — Venture investor with stakes in ecommerce SaaS, speaking generally

Klaviyo has not commented on any acquisition interest in Attentive. Attentive did not respond to questions about its valuation or board-level strategic discussions.

What Does This Mean for DTC Merchants Caught in the Middle?

For operators actually running SMS programs, the instability — if real — carries practical consequences. Merchant sources who work directly with Attentive enterprise reps say account management continuity has become a genuine concern. Two Shopify merchants with lists above 500,000 subscribers told Ecommerce Times they’ve experienced account rep turnover twice in the past six months, creating friction in campaign execution and delayed onboarding of new automation features.

One DTC brand founder in the home goods category, who asked not to be identified, said she’s actively running a parallel evaluation of both platforms heading into Q3 — not because of performance issues, but because she wants optionality if the talent situation at her current vendor gets worse. “We’re not switching. But we’re definitely not signing a two-year renewal right now,” she said.

• Merchants on multi-year Attentive contracts should review rep assignment language and escalation clauses before renewals
• Agencies managing SMS retainers should document institutional knowledge independently of platform-assigned CSMs
• Brands with lists above 250K subscribers may have negotiating leverage given both platforms’ aggressive growth targets in H2 2026
• Klaviyo’s unified dashboard remains the path of least resistance for merchants already running email through the platform — consolidation pressure is real

Will Either Company Blink First?

Sources say both companies are aware that the public optics of an open talent war are damaging — particularly at a moment when enterprise buyers are scrutinizing vendor stability more carefully than at any point in the past three years. Klaviyo’s communications team has reportedly flagged the reputational risk of being seen as an aggressive poacher in a market where it’s already the dominant player.

On Attentive’s side, sources say the company’s people team is working on a retention package expected to roll out to enterprise-facing roles before the end of Q2. Whether it will be enough to stabilize the org is unclear. One former Attentive employee, who left earlier this year for an agency role, put it bluntly: “The product is still genuinely good. But when your competitor is offering a 30% bump and they know your name before they even call you, that’s a hard conversation to have with yourself.”

Neither Klaviyo’s Andrew Bialecki nor Attentive’s Brian Long has addressed the situation publicly. Ecommerce Times will continue to monitor developments as the H2 2026 renewal cycle heats up.
