Customer-led growth is the most sustainable and cost efficient growth model for B2B companies in the AI era. But the systems that support it have not caught up.
Today, we are excited to announce Base’s acquisition of EverAfter AI. Together, we are building the first Engagement OS: a unified operating system for post-sale growth through data driven and AI-powered customer experiences.
This is not about expanding a feature set. It is about reimagining post-sale customer engagement and fixing structural challenges in B2B customer experience, cross-team collaboration, data hygiene, user activation across the lifecycle, and consequently influencing how growth is created after the deal is signed.
EverAfter built a great product that CS and Digital CS teams love for onboarding and ongoing programs. Together with their execution oriented team and passion to customer experiences, we’re creating a new foundation for B2B lifecycle engagement, a canvas for any customer program, with four core pillars:
Single source of truth - customer engagement data that includes internal and external touchpoints, actions, and unstructured data modeling.
Real-time insights - AI powered insights on the contact and account level like never before.
Activation - hyper personalization, engaging and generating outcomes from customers along their journey with the product, community, and customer programs.
Attribution - tracking revenue influence through adoption, upsell & expansion, advocacy & UGC, feedback & VOC, retention marketing, and more.
We’re also introducing powerful AI foundations, allowing creativity and huge time saving, with the first vibe-coding designated customer programs, first AI Upsell Agents, a CLG Agent marketplace, UGC studio, and so much more.
In most organizations, post-sale execution is fragmented by design.
Customer Success, Marketing, Sales, and Product all operate with different tools, data, and customer programs. It was built this way to serve, at most parts, the specific goals of each department, yet this structure hinders the greater organizational growth goal. Customer experiences are mostly subpar. Think 5 different logins, 4 different people reaching out to a customer with an ask the same week, customer feedback or context isn't shared across teams, and the list goes on. Context resets as customers move through the lifecycle. Signals get lost. Engagement becomes episodic. Growth stalls before it compounds. Customers fail to fully adopt the product, advocate, expand the use case, or retain, because the journey is broken.
The catch is that AI can make this worse if not implemented with a CLG framework in mind. You see, when the lifecycle context is broken, more data and automation amplify noise instead of insights.
The result is familiar:
This is not a tooling issue. It is an operating system issue.
Just as CRMs unified pre-sale engagement, the Engagement OS unifies post-sale growth.
The Engagement OS connects data, context, and action into one continuous lifecycle system. It is designed around how customers actually engage, adopt and feel included, and grow, not how teams are organized internally.
With the Engagement OS:
EverAfter was built on a belief we strongly share: product experience and customer experience should not be separate.
EverAfter pioneered customer-facing interfaces that turn post-sale programs into structured, digital experiences. As customer data became fragmented across systems, EverAfter productized post-sale work so customers could experience progress, not process.
Key programs include digital onboarding, adoption journeys, success plans, upsell & expansion, retention marketing and more. The team at EverAfter also built innovative AI modules designated for customer programs. We’re excited to merge teams and products.
By bringing EverAfter into Base, we close a long-standing gap between Customer Success execution and Customer Marketing activation.
Together, we are unifying:
Into one operating layer.
For existing customers of Base and EverAfter, there is no immediate change, only new possibilities.
You will continue to receive full support from the same teams. We will share new functionality and use-cases you can leverage today, and in the coming months, you will see new Engagement OS capabilities introduced as the products are thoughtfully integrated.
What becomes possible:
This is about reducing complexity while increasing impact.
We are excited to welcome Noa Danon, EverAfter’s CEO and Co-founder, Tal, CTO & Co-founder, and the entire EverAfter team to the Base family.
We are inspired by what our work together will enable. All of us together will be even more customer obsessed. As we build the first Engagement OS and a new foundation for customer-led growth!
Join me and Noa Danon for an exciting webinar where we'll introduce The AI Blueprint for Orchestrating Post-Sale Engagement, February 2 at 12pm, save your seat here.
We are just getting started.
