Nosto

Nosto is a Helsinki-based commerce experience platform for online stores. It personalizes the shopping journey on the storefront, not in the inbox. The product comes in two suites. The Product Experience Cloud covers personalized and AI search, category merchandising, product recommendations, post-purchase upsell, dynamic bundles and recommendation blocks for email. The Content Experience Cloud covers A/B testing and optimization, content personalization, behavioral pop-ups and shoppable user-generated content, which came from Nosto's 2021 purchase of Stackla. An AI layer called Experience.AI and an agent named Huginn sit under both suites and handle segmentation, insights and automation. Nosto also bought the search providers SearchNode and Findologic. The platform fits mid-market and enterprise retailers on Shopify, Shopify Plus, Salesforce Commerce Cloud, Adobe Commerce, BigCommerce and Shopware. Brands such as Muji, Vuori and Marc Jacobs appear among its 1,500+ customers. It connects to Klaviyo, Attentive, Yotpo, Tapcart, Trustpilot and Google Analytics. Developers get GraphQL and REST APIs, a JavaScript API, React and Web Components libraries, and native mobile support. Pricing is quote-only. You pay a base platform fee plus a fee based on store GMV and traffic, and the total depends on which modules you choose and what support and scalability level you need. AI features come with every module at no extra cost. The optional Product Scalability Package adds a 99.99% uptime SLA and dedicated infrastructure. There is no self-serve trial, only a structured proof of concept for qualified merchants. The main limitation is that Nosto does not send email or SMS campaigns itself. It adds recommendations and on-site experiences next to an ESP such as Klaviyo. Reviewers also say pricing is opaque and becomes expensive for smaller, low-traffic stores.
