Klaviyo Acquired Napkin.io

Klaviyo recently announced it acquired Napkin.io. Founded in January 2021 by Nick Sypteras, Napkin.io provides developers an easy and secure way to write and deploy code directly from a browser. The code, once live, 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. As part of the acquisition, Sypteras will join the Klaviyo team, reporting to 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 he is passionate about the developer experience. We’re excited to see what we can build together.”

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 enhance the overall developer experience.
