Is Attentive Poaching Klaviyo’s Top Enterprise Account Teams?

Something unusual is happening in the email and SMS martech corridor, and it’s making executives at both companies uncomfortable. According to multiple sources close to the matter, Attentive has allegedly been running a structured, recruiter-led campaign to pull senior enterprise account managers and customer success leads directly out of Klaviyo’s Boston headquarters — and the effort reportedly accelerated sharply after Klaviyo’s Q4 2025 earnings call, where the company disclosed slower-than-expected net revenue retention in its enterprise tier.

The alleged operation is not random. Sources say Attentive’s talent acquisition team has been specifically targeting Klaviyo account managers who oversee merchants doing over $10M in annual GMV — the exact customer segment Attentive CEO Brian Long publicly identified as a growth priority in a March 2026 LinkedIn post. Neither Attentive nor Klaviyo responded to requests for comment by publication time.

What Exactly Is Attentive Allegedly Doing Inside Klaviyo’s Enterprise Book?

The picture being drawn by insiders is pointed. Sources familiar with Klaviyo’s internal culture describe a wave of LinkedIn outreach beginning in late January 2026, with Attentive-linked recruiters reportedly offering total compensation packages 25–35% above Klaviyo’s current enterprise CS band. One person described as a former Klaviyo account director who allegedly took an Attentive offer in March told a mutual contact the jump was “straightforward math.”

“When a recruiter slides into your DMs with a base that’s $30K higher and an accelerator tied to net retention, you at least take the call. That’s not disloyalty, that’s a market signal,” the individual reportedly said, according to a source who relayed the exchange.

The strategic logic, if the reports are accurate, is not subtle. Enterprise customer success managers at Klaviyo carry deep relationship equity with top DTC and Shopify brands. If those managers move to Attentive, they bring institutional knowledge of customer pain points, contract renewal timelines, and the specific integration stacks merchants are running — information that would have obvious value to a direct competitor trying to displace Klaviyo’s email dominance in the $1M–$50M DTC brand tier.

How Is Klaviyo Reportedly Responding Internally?

Unconfirmed reports suggest Klaviyo’s VP of People Operations has convened at least two all-hands meetings in Q2 2026 focused on retention, including a reportedly revised equity refresh program for employees at the L5 and above band — which includes enterprise account management roles. Klaviyo went public on NYSE in September 2023, and its stock performance through early 2026 has been uneven, which sources say has reduced the retention pull of unvested RSUs for some mid-tenure employees.

“The RSU math just doesn’t hit the same when the stock is range-bound. Cash and accelerators are doing more heavy lifting in retention conversations than equity right now,” said one agency founder who works closely with both platforms and claims to have heard this directly from a Klaviyo employee.

Klaviyo’s Chief Revenue Officer Amanda Whalen has not made any public statements on the matter. Internally, sources allege that retention bonuses in the range of $15,000–$40,000 have been quietly extended to key enterprise account leads as a counter-measure, though this is unconfirmed and could not be independently verified by Ecommerce Times.

Which DTC Brands Are Allegedly Being Targeted in the Wake of These Moves?

The downstream concern — and the reason operators in the Shopify ecosystem are paying attention — is what happens to enterprise merchant accounts when their primary relationship contact walks out the door. Sources describe a pattern where departing Klaviyo account managers have allegedly been reaching out to former book-of-business contacts within 30–60 days of joining Attentive, pitching migration conversations framed around Attentive’s SMS-first capabilities and its newer AI send-time optimization features.

Brands allegedly approached in informal pitches reportedly include mid-market DTC players in the home goods, apparel, and wellness categories — all verticals where Klaviyo has historically dominated and where Attentive has been loudest in its 2026 product marketing. One agency operator running email programs for roughly 40 Shopify brands described the dynamic this way:

“We’ve had two clients reach out in the last six weeks saying their Klaviyo rep is gone and they got a migration deck from someone who was at Klaviyo three months ago. That’s not a coincidence — that’s a play.”

Specific brand names could not be confirmed, and it is worth noting that customer relationship outreach following an employment change can be legally complex depending on non-solicitation agreements — which Klaviyo is known to include in enterprise employee contracts.

Is This Actually Hurting Klaviyo’s Enterprise Metrics?

Hard numbers are difficult to pin down given that Klaviyo’s next earnings disclosure is not until August 2026. However, sources close to several Shopify Plus agency partners — including firms that monitor platform usage data across client stores — suggest anecdotal churn signals are ticking upward in the $10M–$30M GMV merchant tier specifically. That’s a significant cohort: Klaviyo has historically monetized this segment at blended ARR values of $24,000–$60,000 per merchant annually, according to publicly available pricing estimates and agency benchmarks.

The broader competitive context matters here. Attentive raised a reported $470 million in its 2021 Series E at a $10 billion valuation and has been navigating a more constrained capital environment since. A move upmarket into Klaviyo’s enterprise base — rather than competing purely on SMS in the SMB tier — would represent a meaningful strategic pivot, one that Brian Long has been telegraphing in various industry appearances throughout early 2026.

• Klaviyo’s enterprise NRR was reportedly cited internally as a watch metric after Q4 2025 results, per sources
• Attentive’s recruiter activity on LinkedIn targeting Klaviyo CS staff allegedly spiked between January and April 2026
• Agency partners report at least five separate migration conversation inquiries from brands with departing Klaviyo contacts in Q2 2026
• Klaviyo equity refresh and retention bonus activity reportedly accelerated in response, though amounts are unconfirmed
• Non-solicitation enforcement remains a potential legal lever Klaviyo has not yet visibly deployed, per sources

What Do Agency Leaders and Operators Think Is Actually Going On?

The prevailing read among agency operators and DTC founders who spoke with Ecommerce Times on background is that this is less a scandal and more a predictable consequence of two well-funded martech competitors playing for the same enterprise dollar at a moment when CAC for new merchant acquisition is rising across the board.

“Recruiting from competitors is standard. The difference here is alleged targeting precision — not just ‘hire from Klaviyo’ but ‘hire the people who own the relationships with the merchants we most want to close.’ That’s a different level of intention,” said one DTC growth consultant who has advised brands on platform stack decisions for six years.

Others are watching to see whether Klaviyo escalates legally. The company has previously enforced non-solicitation clauses in high-profile employee departures, though litigation of this nature often settles quietly and never surfaces publicly. The more immediate question for operators is practical: if your Klaviyo account team changes and a competing platform makes contact, what does your migration cost-benefit actually look like in 2026?

“Switching email platforms at $20M GMV is a six-figure decision when you account for migration labor, list re-warming, flow rebuilds, and the inevitable deliverability dip. Anyone pitching a switch needs to clear a very high bar — a new face with a deck is not that bar,” said one Shopify Plus agency owner who manages email programs across 60-plus brands.

What Should DTC Operators Do If They’re Caught in the Middle?

Practical guidance from agency leaders who have navigated platform transitions before:

• Document your current flow architecture before any platform conversations begin — having a platform-agnostic audit protects you regardless of which direction you move
• Request a formal account handoff meeting from Klaviyo if your primary contact has changed; you are entitled to continuity documentation under most enterprise contracts
• Run a parallel SMS audit before entertaining Attentive pitches — the real question is whether your SMS program is underperforming, not whether your email rep changed jobs
• Benchmark migration costs honestly: list migration, flow reconstruction, integration QA, and a 60-day deliverability stabilization period should all be line-itemed before any LOI is signed
• Consult your agency partner before responding to unsolicited platform migration decks, particularly if they arrive from someone you previously knew in a vendor capacity

For now, both Attentive and Klaviyo are maintaining public silence. But inside the DTC operator community, the chatter is loud enough that several Shopify Plus agency principals have reportedly begun proactively auditing which of their clients have experienced account team changes in the last 90 days. Whether the alleged recruiting campaign constitutes a coordinated competitive strategy or simply reflects normal talent movement in a hot martech sector may ultimately come down to what Klaviyo’s legal team finds when they look closely at non-solicitation terms — and whether they decide the matter is worth the noise of a public dispute.
