Replenit is the AI decision and action engine behind your retention, acting like an individual AI CRM manager for every single customer you have. Most retailers still rely on static flows and broad segments, sending the same journeys to thousands of people who buy and use products at completely different paces. The result is missed repeat purchases, inflated CAC, and CRM channels that feel noisy instead of useful. Replenit sits on your first-party data and your existing stack and turns it into fully individualized, always-on lifecycle decisions. It doesn’t just predict, it acts. For each customer, Replenit autonomously decides, with precise AI prediction, when to engage (the real replenishment or lifecycle moment, not a fixed X-days rule), what to trigger (replenishment, cross-sell, upsell, churn-saving offer, promo, or no message at all), and how to deliver it (email, SMS, app push, web push, WhatsApp, and more). All communication is sent via your existing platforms, including your marketing automation, ESPs, and other tools, with no migration, no replatforming, and no need to rebuild journeys. Replenit becomes the AI brain that feeds these tools with the next best action and uses them to execute end to end. If you have 1 million customers, Replenit runs 1 million individualized, autonomous journeys, continuously adapting timing, product, and message for each person without manual rule-building or daily babysitting. Retailers using Replenit have achieved up to 340% uplift in
