Klaviyo, Inc.
Klaviyo sells software that helps online brands store customer data and run marketing campaigns across email, text, and other channels.
Klaviyo is a software company that helps online brands talk to their customers. If you sell shirts, coffee, or skincare on the internet, Klaviyo is the tool that remembers who bought what, then automatically sends the right email or text message to bring that person back. It's built for the kinds of businesses that live and die by repeat customers, not one-time sales.
The core idea is simple. A brand plugs its store, usually a Shopify one, into Klaviyo, and the platform sucks in every order, click, and browsing habit. That data becomes a single profile for each shopper. Then Klaviyo's automation kicks in: a cart gets abandoned, a text reminder goes out; a customer buys twice, they get a loyalty nudge; someone browses a jacket but doesn't buy, a targeted email follows. The brand pays Klaviyo a monthly subscription that scales with how many contacts it stores and how many messages it sends, so the bill grows as the customer list grows. What makes Klaviyo strong is that it started as the underdog for small merchants and grew up with them. Its deep, native ties to Shopify made it the default choice for direct-to-consumer brands, and it has pushed into bigger customers and new channels like text messaging and customer service. Rivals include Salesforce and HubSpot at the enterprise end, plus cheaper point solutions for email alone. Klaviyo's bet is that owning the data and the whole customer relationship beats stitching together five separate tools.
The company is headquartered in Boston and went public on the New York Stock Exchange in September 2023. It has scaled fast, crossing a billion dollars in annual revenue, but it also carries the risks of its niche: it leans heavily on e-commerce spending, faces stiff competition, and must keep spending on sales and product to stay ahead. The simple way to see it: Klaviyo is the memory and the megaphone for online brands, and it gets paid every month to keep those customers coming back.
