Grafana Labs is the company behind Grafana, the widely used open-source dashboarding and observability platform. Founded in 2014 to commercialize Torkel Odegaard's visualization tool, it has grown into a full-stack observability vendor built on a 'big tent' philosophy - letting teams unify metrics, logs, traces and profiles from any source without ripping out existing tools. Its LGTM stack (Loki, Grafana, Tempo, Mimir) plus Grafana Cloud and Grafana Enterprise now serve more than 7,000 paying organizations, including roughly 70% of the Fortune 50, with the business surpassing $400M in annual recurring revenue and a $6B valuation.
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.
Last9 is a unified observability company that helps engineering and DevOps teams monitor high-cardinality metrics, logs, and traces without the ballooning costs of legacy tools. Built around a Prometheus- and OpenTelemetry-compatible telemetry warehouse called Levitate and a pre-ingestion Control Plane that filters, reshapes, and routes data, Last9 has been used to observe some of the largest live-streaming events in the world - including peaks of roughly 59-61 million concurrent viewers. Founded in 2020 and backed by Sequoia/Peak XV's Surge, Better Capital and others, it targets cost-efficient, full-fidelity observability at enterprise scale.
Observe is an AI-powered observability platform that unifies logs, metrics, and traces into a single streaming data lake built on Snowflake. The company helps enterprises troubleshoot distributed applications 3x faster at one-third the cost of traditional monitoring tools. 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.

Patrick Campbell bootstrapped ProfitWell (originally Price Intelligently) from a cashed-out 401k into one of the most cited SaaS pricing authorities on the internet, serving 30,000+ companies for free before selling to Paddle for $200 million in 2022. Known as @Patticus, he turned a debate scholarship, a stint at the NSA, and a barista certificate into a decade-long conviction that pricing is the most underleveraged growth lever in SaaS.
