Coralogix

Coralogix operates a cross-stack observability platform that unifies systems monitoring (log analytics, APM and tracing, infrastructure and metrics, real user monitoring), AI observability (discovery, evaluation, guardrails, AI security posture management) and security capabilities (SIEM, CSPM, MDR) in a single product. The platform is built on an index-free architecture in which telemetry is analyzed in-stream and stored in the customer's own cloud storage, such as an S3 bucket, in open formats and queried remotely without rehydration, supporting long-term retention and high-cardinality data.

Data is ingested from external sources via Kafka Connect, streamed through Kafka for parsing, enrichment and machine-learning-based clustering, then routed to downstream destinations, with support for open standards including OpenTelemetry and Prometheus. Users query across signal types with the DataPrime engine and a unified syntax, and can build cross-stack dashboards, in-stream alerts and reusable datasets. A Cost Optimizer routes low-value data to customer storage while keeping critical logs available for immediate analysis. Enterprise controls such as RBAC, SSO with SAML, audit trails, IP access control and cross-team quota management are included, with no limits stated on sources, users or hosts.

Alongside the traditional dashboard interface, Coralogix offers AI-first entry points: Olly, a conversational investigation agent introduced in 2025; a Model Context Protocol connector that surfaces insights in tools such as Slack, PagerDuty and IDEs; and a command-line interface for scripted or automated investigations. According to the company's CEO, more than half of enterprise customers use Olly or their own models through CLI and agentic interfaces to investigate incidents.

Founding story

CEO Ariel Assaraf founded Coralogix after four years of struggling with unmanageable log data, with the goal of simplifying log analytics; co-founder and CTO Yoni Farin, who has more than 25 years of experience in software development, big data and distributed systems, architected the platform. The company's about page dates the founding to 2014, as does TechCrunch; Calcalist reports 2015.

Business model

Coralogix sells a subscription SaaS observability platform to engineering and security organizations. Enterprise capabilities such as RBAC, SSO, audit trails and compliance controls are included rather than sold as add-ons, and the company states there are no per-user, per-host or per-source limits, with pricing positioned around data value tiers and a cost optimization tool that offloads low-value telemetry to customer-owned storage.

Recurring platform subscriptions tied to telemetry data usage rather than user, host or source counts; the company reports roughly 30 customers spending more than $1 million annually.

Traction

More than 5,000 customers worldwide including IBM, Tradeweb and JFrog; revenue grew more than 60% over the year to June 2026, with an annual run rate of $150-200 million and about 30 customers paying over $1 million annually. The company surpassed $100 million in annualized revenue more than a year before June 2026. It employs more than 600 people globally, holds 192 G2 badges, and says it does not expect to raise further capital while working toward profitability over the next few years.

Latest developments

In June 2026 Coralogix announced a $200 million Series F at a $1.6 billion post-money valuation co-led by Advent, CPPIB and Greenfield Partners with participation from Brighton Park Capital and existing investors; less than 10% of the round funded a secondary share sale for long-time investors. Proceeds are earmarked for AI-driven observability with autonomous agents, scaling the Data Lake architecture for long-term enterprise-scale data processing, security offerings, and expansion among large enterprises in fintech, cybersecurity and cloud infrastructure. The company says it is preparing to operate with the financial discipline of a public company without committing to an IPO timeline.
