Klaviyo, Inc. and Salesforce, Inc. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between Klaviyo, Inc. and Salesforce, Inc..

Klaviyo, Inc. business model: Klaviyo sells software subscriptions to consumer brands. Email plans are priced mainly by the number of active profiles a brand stores; SMS and WhatsApp are sold as message credits; and add-ons such as Klaviyo CDP, Reviews, Customer Hub/service tools and AI agents raise spend per account. A free tier lets small stores start without a sales call, and pricing rises automatically as a merchant's list and send volume grow. Revenue expansion comes from three levers: customers growing, customers adding channels, and customers adopting more products. At June 30, 2026, 20% of ARR came from customers using three or more products and net revenue retention was 109%.

Salesforce, Inc. business model: Salesforce sells multi-year software subscriptions, mostly priced per user per month, plus consumption pricing for Data 360 and Agentforce. In fiscal 2026 (ended January 31, 2026), subscription and support revenue was $39.39 billion, about 95% of the $41.53 billion total; professional services added $2.14 billion. Subscription revenue is reported in five offerings: Agentforce Service, Agentforce Sales, Agentforce 360 Platform/Slack/Other, Agentforce Integration and Analytics (MuleSoft, Tableau, Informatica), and Agentforce Marketing and Commerce.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of Klaviyo, Inc. stack up against those of Salesforce, Inc..

Klaviyo, Inc. competitive advantage: Klaviyo's edge is data plus distribution. Its event database stores every product view, cart and order alongside the customer profile, so segmentation and triggered messages work in near real time without an outside data warehouse. Its Shopify integration and partner network make it the default retention tool for many mid-sized online brands, and its self-serve pricing lets small stores start cheaply and grow into enterprise contracts.

Salesforce, Inc. competitive advantage: Salesforce's advantage is switching cost. Large customers build years of custom objects, workflows, integrations and AppExchange apps on the platform and train administrators on it, so replacing it means re-implementing core sales and service processes. Owning Slack, MuleSoft, Tableau and Informatica also lets Salesforce sell data, integration and collaboration around the CRM record.

Future prospects matter as much as current results. The growth strategies below explain how Klaviyo, Inc. and Salesforce, Inc. each plan to expand from here.

Klaviyo, Inc. growth strategy: Klaviyo is pushing upmarket (4,477 customers paid more than $50,000 in ARR at June 30, 2026, up 36%), expanding abroad, cross-selling SMS, WhatsApp, Reviews, CDP and service products, and repositioning from email tool to autonomous B2C CRM. Partnerships with Shopify, Stripe, Anthropic and Figma extend where its data and agents can be used.

Salesforce, Inc. growth strategy: Salesforce is pushing three levers: Agentforce AI agents priced on consumption or flex credits, Data 360 (formerly Data Cloud) to unify customer data, and the Informatica acquisition, closed in November 2025, to add data management and governance. It also cross-sells Slack as the interface for agents and keeps buying back stock under a $50 billion authorization announced in February 2026.
