A brief history of Calyptia

Born from the need

In 2014, the Fluentd creators — then working at Treasure Data — were solving data collection and processing problems at high scale already, but they saw the need of a lightweight log processor for constraint environments like Embedded Linux.

They decided to start with an open-source project – Fluent Bit – to solve the problem of how to collect data in a reliable way for multiple devices, and create something that could sustainably improve over time.

Over the years, Fluent Bit became Apache 2.0 licensed, and recorded more than 2 million deployments a day globally. Fluentd became one of the earliest CNCF graduated projects. This technology was solving a real problem.

As creators and maintainers of the Fluent projects, Calyptia co-founders Eduardo Silva and Anurag Gupta started seeing lots of issues, pull requests and contributions on GitHub. It was a good time to start a relationship with this vibrant community, and support enterprises in their quest for first-mile observability without vendor lock in.

And with an agile hummingbird as the next natural logo in the Fluent progression, Calyptia was born as a bridge between first-mile data and the enterprise.
