NEWPORT BEACH, CA - September 22, 2025 - Bread Loaf, a top Klaviyo agency partner and the team behind Retention Labs, announces its participation in Klaviyo’s K:BOS, the company’s flagship conference taking place September 25–26, 2025 at the Hynes Convention Center in Boston, MA. The two-day event will convene consumer brands, partners, and practitioners for keynotes, hands-on sessions, and a first look at Klaviyo’s product roadmap.
This year’s featured speakers include Mike Cessario (Founder & CEO, Liquid Death), Paige DeSorbo (Founder & Co-Host, Daphne & Giggly Squad), Hilary Castleman (Head of CRM, Princess Polly), Andrew Bialecki (Co-Founder & CEO, Klaviyo), and Valeria Dediu (VP of Growth Marketing & Ecommerce, Away)—alongside a deep bench of brand and platform leaders across retail, beauty, apparel, CPG, and beyond.
A long-awaited return for the eCommerce community
K:BOS is back after a multi-year hiatus following its 2019 edition, answering what many in the eCommerce community have been asking Klaviyo for: a large-scale Boston gathering centered on customer-first growth, data, and lifecycle marketing. The 2025 program brings road-map reveals, zero-party data workshops, and networking among operators, agency leaders, and technology partners.
Klaviyo has also announced that it will host an Investor Day on Thursday, September 25 in conjunction with K:BOS, offering a deeper look at strategy and platform innovation.
Bread Loaf on the ground in Boston
Mark Milutin, Founder & CEO of Bread Loaf and host of The Brand Building Podcast, will attend K:BOS to connect with brand operators, tech partners, and fellow Klaviyo practitioners—and to cover the biggest takeaways for retention marketers in the Shopify ecosystem.
“I have been waiting to attend K:BOS for over 8 years now and I can’t wait to participate in this year’s event in Boston,” said Mark Milutin, Founder & CEO of Bread Loaf. “Bread Loaf is considered one of the top Klaviyo agency partners in the world—it’s our favorite CRM platform and the only tool we recommend to Direct-to-Consumer brands in the Shopify ecosystem.”
In addition to on-site coverage, Bread Loaf will host an invite-only dinner on Thursday, September 25 for select brands, agencies, and technology partners.
