Our story

There once was a small team of developers and designers building a lot of APIs. They needed help not just with building but with documenting, maintaining and shipping.

There wasn’t anything out there that could help, so they built something themselves. That something is an API-specific platform now known as Treblle.


The beginning- A Leap of Faith

In July 2021, Treblle secured a $1.4M seed investment led by Nauta Capital. The initial idea hasn’t changed much to this day, and that is that the Treblle team wants to give you the best API observability and visibility possible.

7M raised in Series A

In December 2022, Treblle secured a $7M Series A investment. After a year of figuring out things, launching Treblle 2.0, and getting almost 20K new users, we arrived at this big milestone. The milestone that we are sure is going to be the thing that desired unicorn status.


Industry Leader in Innovation in API Space

Treblle was named an IDC Innovator in the IDC Innovators: Integration and API Management Tools and Technologies, 2023 report. IDC is after Gartner and Forester, the largest and most significant analyst company. This report signals we are definitely sailing in the right direction.
