Klaviyo Acquires Napkin.io


Klaviyo, a unified customer platform that provides data-driven marketing tools, including email and SMS, for ecommerce businesses, announced the acquisition of Napkin.io.

Founded in January 2021 by Nick Sypteras, Napkin.io provides developers with an easy and secure way to write and deploy code directly from a browser. The code, once it lives, can be set to run on a schedule or deployed as an API endpoint. Napkin.io is Klaviyo’s first acquisition and underscores the company’s continued commitment to the developer community. Sypteras will join the Klaviyo team as part of the acquisition, reporting to the VP of Data Science Ezra Freedman.

“Klaviyo is focused on providing the best possible experience for our customers – and that means opening up our platform to allow developers to build on top of our existing offerings,” said Ed Hallen, co-founder and Chief Product Officer of Klaviyo. “Last year, a few members of our team discovered Napkin.io and were immediately impressed with the power of the software, clear user interface, and unique feature set, which are all Klaviyo-level quality. Further, Nick shares our vision and DNA as a builder and creator and is passionate about the developer experience. We’re excited to see what we can build together.”

“When I started working with the Klaviyo team, I was struck by how similarly we think about empowering creators,” said Nick Sypteras, founder of Napkin.io. “Napkin.io was founded on the premise that we need a more powerful way to turn an idea into running code quickly with no set-up, no dependencies and no slog. Klaviyo customers know they can launch a campaign in an hour and go from an idea in the shower to money in the bank on the same day. As code continues to eat the world, it’s only right that we have a more powerful way to support the ideas brands have to serve their customers better. I’m thrilled to become a Klaviyo and work alongside the team to build best-in-class solutions for our customers.”

Earlier this year, Klaviyo committed to expanding its platform to enable developers, customers, partners, and freelancers to build new experiences on top of Klaviyo. To achieve this, Klaviyo launched new SDKs, a sample data tool to speed up Klaviyo onboarding, and a new developer portal making it easy to find API documentation, guides, and developer-specific content.

To continue to deliver on this promise, today, in addition to the acquisition, Klaviyo announced the public release of its new Klaviyo APIs. These new endpoints are more consistent and more connected while enabling more programmatic access to new product areas. For example, developers can utilize Klaviyo’s new Catalogs API to programmatically create, update, or delete catalog data in a customer’s account to send more personalized messages ensuring accurate product information in Klaviyo. Over the coming months and throughout 2023, Klaviyo plans to continually release new APIs exposing more of its UI and enhancing the overall developer experience.
