Base AI announced it has acquired EverAfter AI, combining Base’s customer lifecycle marketing capabilities with EverAfter’s customer-facing post-sale experiences to create what the companies call the first “Engagement OS” for B2B customer-led growth.
The combined platform is intended to unify customer lifecycle marketing and digital customer success into a single system that helps companies drive adoption, expansion, revenue, advocacy, community engagement, and retention through AI-based activation and personalized experiences. Base positioned the deal as a response to increasingly fragmented post-sale tooling, arguing that disconnected systems limit the effectiveness of automation by stripping away context across customer touchpoints.
Base said the Engagement OS is designed around three goals: improving net revenue retention by supporting upsell and expansion while reducing churn through better adoption and lifecycle engagement; using AI and AI agents to improve customer data quality, personalization, and real-time activation; and lowering costs by consolidating tools and streamlining customer experiences across post-sale journeys.
The companies said the platform will bring together real-time customer signals and sentiment into a unified view, enabling teams across marketing, customer success, sales, and product to coordinate lifecycle-aware actions. Base also emphasized attribution and “revenue growth frameworks” intended to connect post-sale engagement efforts with measurable outcomes, positioning the Engagement OS as infrastructure for AI-driven go-to-market execution rather than a set of point solutions.
Gal Biran, CEO and co-founder of Base AI, said B2B customer experience has “never [been] built as a system,” instead evolving around organizational silos. Biran added that EverAfter’s technology demonstrated how data-driven, programmatic post-sale engagement can influence net revenue retention, and said the acquisition is aimed at orchestrating post-sale activation and outcomes across onboarding, adoption, advocacy, and expansion in a single operating model.
Noa Danon, CEO and co-founder of EverAfter AI, said EverAfter was founded on the belief that product experience and customer experience should not be separate. Danon said EverAfter “productized” post-sale work into digital experiences as customer data became fragmented across disconnected tools, and described the combination with Base as closing a long-standing gap.
Base said customers of both platforms will continue to receive full support as the products are integrated, with new Engagement OS capabilities rolling out over time. The companies also said they plan to outline their roadmap and “AI blueprint” for orchestrating customer-led growth in a live webinar featuring Biran and Danon.
Base and EverAfter said their products are used by B2B organizations including Adobe, Zendesk, Broadcom, ZoomInfo, Okta, Vidyard, and Salesloft.
KEY QUOTES:
“The B2B customer experience is inefficient and detrimental to growth because it was never built as a system. It evolved around org structures and GTM silos, instead of customer centricity and LTV. What Noa Danon and the EverAfter team built made one thing clear: data-driven programmatic post-sale customer engagement can influence NRR. This acquisition is about building the first Engagement OS, to orchestrate any post-sale activation and measurable outcome across the customer lifecycle while providing Marketing, CS, Sales, and Product teams a single source of truth with AI-based insights and revenue growth frameworks.”

“EverAfter was built on a simple belief: product experience and customer experience should not be separate. We productized post-sale work into digital experiences as customer data became fragmented across disconnected tools. Bringing this technology into Base AI closes a long-standing gap.”
