1 + The future of B2C is being built right here in Boston-powered by AI, connected across every channel, and grounded in human connection. That was the main takeaway from K:BOS 2025.

2 From live product debuts to honest conversations with the founders and marketers behind some of today’s fastest-growing brands, this year’s event wasn’t just about what’s possible in B2C. It was about what’s already happening.

3 The city buzzed with energy as attendees packed into sessions, swapped ideas in hallways, and witnessed firsthand how AI and data are reshaping the way brands serve their customers. The excitement was palpable, the strategies actionable, and the vision clear.

4 Here are 10 takeaways from the keynote, breakout sessions, and customer panels that will define how marketers grow in 2025 and the years ahead.

5 <h2>1. The keynote redefined what it means to “work with AI”</h2>

6 Klaviyo co-founder and CEO Andrew Bialecki opened K:BOS 2025 with a bold but practical message: the future isn’tAI versus people-it’sAI with people. Results come when we map the work.

7 Mapping the work means becoming great at teaching agents what our routine is and what we expect: the steps, the sequence, and the rules to how and why we create. Once roles are broken into clear tasks-and enriched with the right context like brand voice, policies, product data, and customer history-marketers and service leaders can decide which tasks AI should make easier, while keeping people in the loop.

8 - At K:BOS 2025, Klaviyo introduced two new AI agents purpose-built for this type of work.

9 <h3><a>K:AI Marketing Agent</a></h3>

10 The K:AI Marketing Agent makes the routine of campaign management explicit. It autonomously plans and launches campaigns in minutes, writes on-brand content, personalizes every send, and continuously learns without constant prompting-so your teamdirectsthe work instead of doing it.

11 <h3><a>K:AI Customer Agent</a></h3>

12 The same approach applies to service. Great agents don’t just answer questions-they act. The K:AI Customer Agent can check inventory, recommend products, start exchanges or returns, and reason across sub-agents to complete multi-step tasks, escalating to a human only with full context.

13 <h3>Shared foundations & safety</h3>

14 Both agents operate on unified customer profiles and brand guardrails. Preflight checks, policy-aware permissions, consent and frequency caps, and human-in-the-loop approvals ensure every action is safe, compliant, and on brand.

15 <h3>The shift & takeaway</h3>

16 The shift isn’t about replacing people-it’s about mapping tasks and context clearly. That’s how you teach agents, reduce handoffs, speed outcomes, and grow revenue, while your team focuses on what only humans can do: creativity, empathy, and strategy.

17 Stop worrying about AI replacing roles. Start asking: how can we direct AI agents by mapping the work, so human creativity and customer empathy drive the most impact?

18 <h2>2. Fashion brands are blending culture, data, and zero-party insights</h2>

19 InBeyond the Rack: Style Meets Data, leaders from<a>Princess Polly</a>,<a>Barstool Sports</a>,<a>ThirdLove</a>, and<a>Castore</a>shared how they’re winning in one of the most competitive industries.

20 <ul><li>Princess Pollyis bridging online and offline data to make the customer journey seamless.</li>

21 <li>ThirdLove’sfitting room quiz proves that zero-party data can be both valuable and delightful.</li>

22 <li>Barstoolshows that cultural moments-like big sports events-can fuel community and retention when tied to the right offers.</li>

23 - </ul>Takeaway: Creative will always matter in fashion and merchandise, but the brands breaking out are those that combine creativity with<a>first- and zero-party data</a>. Personalization and experience lead the pack--and the Klaviyo AI suite of personalization tools is here to help.

24 <h2>3. Food & beverage brands are creating crave-worthy journeys</h2>

25 AtFrom Sip to Sale,<a>BIGFACE Coffee</a>,<a>Graza</a>, and<a>Callie’s Hot Little Biscuits</a>revealed how they’re blending automation and authenticity.

26 <ul><li>BIGFACEis using pop-ups and retail shops as cultural connection points.</li>

27 <li>Callie’sis layering education-recipes, stories, handwritten notes-to deepen loyalty.</li>

28 <li>Grazais staying true to brand identity while expanding categories and rewarding subscribers with surprise gifts.</li>

29 </ul>Takeaway: In food and beverage, education and tradition are just as powerful as discounts. Every touchpoint should feel like part of a bigger ritual. And now, brands can speed up the production of content and assets to educate and engage with<a>K:AI Marketing Agent</a>.

30 <h2>4. Winning BFCM starts with the right offer strategy</h2>

31 The breakout sessionCreate the Right BFCM Offer Strategywith<a>Kulani Kinis</a>showed why not all discounts are created equal.

32 Their advice:

33 <ul><li>Anchor in yourgoal(AOV, traffic, subscriptions).</li>

34 <li>Keep it simple-complex, tiered offers confuse both teams and customers.</li>

35 <li>Layer in moments of surprise (daily product drops, gift-with-purchase) to sustain momentum.</li>

36 - </ul>Takeaway: Don’t just discount. Design offers that spark urgency and joy-and leave room for creativity in your messaging. And remember, while consumers are on the lookout for<a>discounts during BFCM</a>, you shouldn’t use a single sweeping strategy. Tier your discounts by new customers versus repeat, by AOV and even channel.

37 <h2>5. Segmentation can 3x your ROI</h2>

38 In3x Your ROI with a Targeted Segmentation Strategy, Klaviyo experts and<a>Filson</a>’s Head of Retention showed how advanced segmentation is the secret weapon for holiday and year-round performance.

39 By ramping sending volume gradually, protecting deliverability, and isolating “opportunity audiences” (like window shoppers), brands are personalizing with precision from first onboarding with Klaviyo through nurturing lifelong customers across every channel.

40 - Takeaway: Stop blasting your list. Invest in exclusions, sunsetting flows, and predictive segments to maximize ROI. Owned marketing with the<a>B2C CRM</a>is layered, especially as you grow and learn more about your customer through first- and zero-party data. Don’t just collect that information. Use it to create more personalized experiences that drive more revenue.

41 <h2>6. Paid ads work harder when powered by your data</h2>

42 InGrow Your Audience and Retarget with Paid Ads,<a>Loop Earplugs</a>showed how they use Klaviyo segments to fuel lookalike audiences that actually convert.

43 <ul><li>47% of BFCM sales come from existing customers-but the other 53%? That’s where<a>lookalike audiences</a>come in.</li>

44 <li>Social proof (UGC, reviews) is becoming the #1 growth lever for ad creative.</li>

45 - </ul>Takeaway: Your CRM is your best ad platform. If your ads aren’t informed by<a>Klaviyo segments</a>, you’re overspending.

48 From<a>Dollar Shave Club</a>’s personalization playbook to<a>2xist</a>’s 61% lift in ROAS using RFM-based audiences, the message was clear: data doesn’t just describe the past anymore-it predicts the next best move.

56 <h2>9. Loyalty and community beat discounts every time</h2>

58 Takeaway: Discounts can create a spike. Community creates compounding returns.

59 <h2>10. The future of B2C is omnichannel, autonomous, and human-centered</h2>

60 Across every session, the throughline was clear: the brands that will win are those that embrace AI to automate complexity, use data to personalize every touchpoint, and lean into the very human side of service and community.

61 - That includes not treating service as a cost center anymore. It’s a revenue channel. Great brands don’t treat marketing and service as silos, but as one continuous experience from a customer’s first touch to repeat purchases and long-term loyalty.

61 + That includes not treating service as a cost center anymore. It’s a revenue channel. Great brands don’t treat marketing and service as silos, but as one continuous experience from a customer’s first touch to repeat purchases and long-term loyalty.

62 Klaviyo Service makes that possible with three products working together:

63 <ul><li><a>Customer Agent</a>for proactive, on-brand conversations that act (returns, exchanges, order updates).</li>

64 <li><a>Customer Hub</a>for self-serve control and dynamic offers.</li>

65 <li><a>AI-powered helpdesk</a>that gives human agents full context when they step in.</li>

66 </ul>Because it all runs on a unified customer profile with shared guardrails, every interaction stays consistent. Service strengthens relationships, accelerates growth, and becomes as much of a revenue driver as marketing.

67 The next decade of B2C belongs to brands that unify their channels, embrace AI agents as copilots, and make every customer interaction-whether it’s marketing or service-feel like it was made just for them.
