Absolute Web grows retainers 30% YoY by expanding beyond development with K:Partners

---

Absolute Web is a digital agency built for ecommerce. With deep expertise in custom development, they help brands launch fast and scale smarter. From fast-growing DTC brands like Summer Fridays to enterprise merchants like Swanson Vitamins, clients rely on Absolute Web to turn strategy into standout digital experiences.

Based in Miami, the team brings deep technical skills and a no-fluff approach to every build. As client needs shifted, they expanded into marketing and growth strategy, using Klaviyo’s partner program to support their evolving services.

Challenge

Absolute Web built its reputation on sharp development and fast execution. With deep platform expertise, the agency handled complex migrations, custom builds, and conversion-led design at speed.

But as the business scaled, so did client expectations. Brands wanted more than beautiful storefronts—they needed measurable results, personalized experiences, and integrated tech stacks that could drive long-term growth.

“Expanding into marketing and growth strategy services was a strategic evolution,” says Sergiu Tabaran, COO at Absolute Web. “Clients were looking for a comprehensive digital partner, one that could support not only web development but also lifecycle marketing, retention, and customer acquisition.”

Recognizing the opportunity to deliver greater value through a fully integrated approach, we brought in experienced specialists, pursued key certifications, and ensured our marketing solutions were seamlessly aligned with our development capabilities.

The shift in demand prompted a shift in strategy. Absolute Web began hiring experienced specialists, pursuing key certifications, and building out a fully integrated offering that aligned marketing and development from day one.

“This expansion has also allowed us to diversify our client portfolio,” Tabaran explains, “particularly among DTC brands seeking long-term optimization beyond the initial launch phase.”

Still, the bar for execution remained high. With clients launching nonstop and leaning on the agency’s ecommerce strategy and technical expertise, Absolute Web couldn’t afford to slow down. They needed a partner who could move with urgency, insight, and precision—and help them deliver on both sides of the funnel.

Solution

Joining K:Partners, Klaviyo’s partner program, marked a turning point for Absolute Web. What started as a development shop evolved into a full service ecommerce agency. “Klaviyo has played a pivotal role in enhancing the value we deliver to our clients,” says Sergiu Tabaran, COO at Absolute Web.

Through K:Partners, the agency gained access to more than product training and templates. They leaned on strategic enablement built around the ecommerce platforms they support plus dedicated support across sales conversations, onboarding, and long-term planning.

We’ve been able to grow our retainer relationships and position Absolute Web as a strategic, long-term partner, not just a project-based development agency but a driver of sustained business growth.

That backing helped them scale their marketing offering quickly and confidently. With Klaviyo, they could pitch bigger deals, move fast on client campaigns, and deliver stronger results without disrupting dev timelines.

Today, Klaviyo is a foundational part of Absolute Web’s offering and a trusted growth partner as the agency continues to expand its services.

Strategy

With support from Klaviyo and the K:Partners program, Absolute Web has built a service model that combines technical execution with performance marketing. The partnership helps them deliver long-term value to ecommerce brands and grow their business in the process:

• Email as a growth engine: Email marketing has become one of Absolute Web’s most effective offerings. Klaviyo enables the team to lead with performance—anchoring campaigns, building customer relationships, and standing out in competitive pitches. What began as a service add-on is now a core pillar of the agency’s value.
• More strategic client relationships: Klaviyo has helped Absolute Web deliver more performance-driven, data-informed work. As a result, they’ve improved retention, engagement, and ROI across accounts—leading to 30% year-on-year revenue growth and a shift from vendor to strategic partner.
• Partnering with clients post-migration:Absolute Web led Capezio’s platform migration, then immediately launched Klaviyo flows, campaign strategy, and A/B testing to drive performance post-launch. For one pet care brand, they redesigned the site while building out a Klaviyo journey—boosting engagement and conversions within 90 days. Across both, the agency delivers full-funnel impact without slowing down execution.

Since expanding our marketing service offerings—with Klaviyo as a core component—we’ve achieved over 30% year-over-year growth in marketing retainers and have significantly increased overall client retention.
