Decibel is a San Francisco-based seed and Series A venture capital firm investing in artificial intelligence, machine learning, and enterprise infrastructure companies, backing technical founders building the software tools, platforms, and frameworks that are transforming how enterprises build, deploy, and operate technology systems. The firm invests with initial checks from $1 million to $5 million at the earliest stages of company development, often leading rounds before significant product traction, and focuses on companies where the founding team's deep technical expertise creates a durable advantage. Portfolio companies include Chronosphere, the cloud-native observability and monitoring platform built by former Uber engineers; Lumos, the IT management and access control platform for enterprise organizations; Gem, the talent acquisition and recruiting intelligence platform for enterprise hiring teams; and Grafana Labs, the open-source analytics and interactive visualization platform that has become the industry standard for observability and monitoring with millions of users globally.
