Kloudfuse is a Cupertino-based observability company that unifies metrics, logs, traces, real user monitoring, continuous profiling, and LLM monitoring into a single observability data lake that runs inside a customer's own cloud (VPC) rather than a vendor SaaS. Founded in 2022 by veterans of Springpath, Nicira, VMware, and Cisco, it pitches an OpenTelemetry-native, AI/ML-powered platform that gives enterprises data ownership and 60-80% cost savings versus incumbents like Datadog. It launched out of stealth in November 2023 with $23M in funding and is used by companies including GE HealthCare, Zscaler, Tata 1mg, and Automation Anywhere.
New Relic is a San Francisco-based, AI-powered observability platform that gives engineering teams a single place to see everything running in their software - from application code and infrastructure to logs, user experience, and AI models. Founded in 2008 by Lew Cirne, it helped popularize application performance monitoring (APM) and later coined much of the modern 'observability' category. After going public in 2014 and being taken private in a $6.5 billion deal in 2023, New Relic now serves thousands of companies with usage-based, consumption pricing and a strong bet on AI and agentic observability.
Observe is an AI-powered observability platform that unifies logs, metrics, and traces into a single streaming data lake built on Snowflake.

Founded in 2017 by veterans from Splunk, Wavefront, and Snowflake, Observe was acquired by Snowflake in January 2026 for approximately $1 billion after raising over $665 million in funding.

Started as an open-source side project in 2008, it now serves more than four million developers and 100,000+ organizations including Disney, Microsoft, Atlassian, and GitHub.
