Profile
ChaosSearch indexes log and event data stored in cloud object storage, making it searchable and analyzable with standard tools like Elasticsearch, SQL, and AI models, without moving or transforming the data.
ChaosSearch, founded in 2017 by Thomas Hazel and Les Yetton and headquartered in Boston, Massachusetts, provides a cloud-based analytics platform that enables search, SQL, and GenAI on log and event data stored in object storage. The company originally operated under the name Chaos Sumo. As of early 2026, the company has raised $59 million in total funding across three rounds, the most recent being a $40 million Series B round announced in December 2020.
Investors include .406 Ventures, Glasswing Ventures, and Stripes. The company reports 53 employees as of 2023 and 13 as of April 2026 per Tracxn, though ZoomInfo lists a range of 51-200 employees. Revenue is listed as under $5 million by ZoomInfo.
In January 2021, the company claimed a 766% year-over-year revenue increase and a tripling of its customer base, managing over 15 petabytes of data. Its platform is marketed as a replacement for Elastic Stack (ELK) and Splunk, offering 50-80% cost savings by indexing data directly in cloud object storage (Amazon S3, Google Cloud Storage) without requiring data movement or pre-defined schemas. The platform supports native Elasticsearch query capabilities and integrates with Databricks Lakehouse.
Notable named customers include Equifax, Cisco, Klarna, Cloud Imperium Games, Blackpoint Cyber, and Revinate. The company was named a Gartner Cool Vendor in 2023. No new funding rounds, acquisitions, or major product launches have been publicly disclosed since the 2020 Series B.

Strengths and what to watch
Strengths
- Direct indexing of cloud object storage eliminates the need for data movement, schema-on-read reduces management toil, and the platform claims 50-80% cost savings over legacy log management solutions like Elastic Stack and Splunk.
- Compatibility with existing Elasticsearch APIs and tools allows teams to adopt the platform without retraining or rewriting queries, lowering switching costs.
- Named enterprise customers including Equifax, Cisco, and Klarna provide credibility in regulated and high-scale environments, and the company was recognized as a Gartner Cool Vendor in 2023.
Watch for
- No public funding or major product announcements since the $40 million Series B in December 2020; the company may be operating on a lean budget or facing challenges raising additional capital.
- Employee count appears to have dropped from 53 (2023) to 13 (April 2026 per Tracxn), which could indicate significant downsizing or a pivot to a smaller, more focused team.
- Revenue is reported as under $5 million by ZoomInfo, which is modest for a company founded in 2017 with a 766% growth claim in 2021; the actual current revenue trajectory is unclear without more recent disclosures.
