Base is creating the AI Engagement OS for post-sale growth. Most B2B companies invest heavily in winning customers - but lack the infrastructure to engage them after the deal closes. The result: fragmented customer journeys, low product adoption, missed expansion opportunities, and preventable churn. Base fixes that. We give companies a single platform to orchestrate the entire post-sale customer lifecycle — across onboarding, adoption, expansion, advocacy, and retention. The Base platform analyzes customer signals across product usage, lifecycle milestones, and engagement touchpoints, and turns them into AI-driven customer journeys that run at scale. This enables companies to move from reactive customer management to proactive, automated lifecycle engagement. With Base, teams can: • Drive product adoption and activation • Identify and capture expansion opportunities • Turn customers into advocates • Increase retention and lifetime value • Run lifecycle engagement programs at scale Customer-Led Growth is the next phase of B2B revenue. Base is building the operating system that powers it.
