About Quesma
Our Background
We've built observability pipelines at Sumo Logic, optimized databases at Facebook (now Meta) and Dynatrace, and worked on the infrastructure that keeps the internet running at Elastic, Scylla, and Intel. Now, we're taking that experience and making querying, transforming, and integrating data less painful.
Quesma is a venture-backed startup (Delaware-incorporated, $2.5M pre-seed) with investors like Heartcore Capital, Firestreak, Inovo and several angels, including Christian Beedgen (Sumo Logic co-founder).
