Confluent

Jay Kreps, Neha Narkhede and Jun Rao founded Confluent in 2014 after co-creating Apache Kafka at LinkedIn. The Delaware company was briefly incorporated as Infinitem, Inc. before taking the Confluent name. It commercialized Kafka-based streaming through an enterprise distribution, a fully managed multicloud service, connectors, governance, Flink stream processing, Tableflow and AI/agent tooling. Confluent raised $455.9m in five announced private rounds: $6.9m from Benchmark, LinkedIn and Data Collective; $24m led by Index; $50m and $125m led by Sequoia; and $250m led by Coatue at a $4.5b valuation. The 2020 S-1 preferred-stock schedule is higher because the Series E capitalization also includes founder-stock tender/secondary conversions; those are not additional company primary capital. Confluent sold 23m Class A shares at $36 in its June 2021 IPO, raising $828m gross. For FY2025 it reported $1.167b total revenue, $1.120b subscription revenue, $624m Confluent Cloud revenue, $295.3m net loss, $64.3m operating cash flow, $2.054b liquidity, $1.460b remaining performance obligations, 1,521 customers above $100k ARR and 3,241 employees in 27 countries. IBM announced an all-cash $31/share acquisition at $11b enterprise value in December 2025 and completed it March 17, 2026. Confluent remains a distinct IBM brand/business; IBM said the platform served more than 6,500 enterprises including 40% of the Fortune 500 at close. Products span Confluent Cloud, Platform, Private Cloud and WarpStream, with Kafka/Kora streaming, 80+ managed connectors, Flink, Stream Governance, Tableflow, Confluent Intelligence and Streaming Agents. Cloud pricing is consumption based: Basic begins at $0, Standard about $385/month, Enterprise about $895/month and Freight about $2,300/month, plus eCKU, ingress/egress and storage charges. Acquisitions include Mesh7, Immerok ($54.9m purchase consideration plus contingent retention) and WarpStream ($135.1m purchase consideration plus up to $84.1m retention). Risks include hyperscaler/open-source competition, IBM integration and customer concentration effects, cloud infrastructure costs, persistent GAAP losses, Kafka ecosystem governance, data-security exposure and source-available licensing controversy. The 2018 Confluent Community License restricted managed-service resale for certain formerly Apache-licensed Confluent components; Apache Kafka itself remained Apache 2.0.

Founding story

Kreps, Narkhede and Rao built Kafka at LinkedIn to turn company activity into scalable real-time streams. Seeing thousands of organizations adopt it but lack surrounding enterprise tooling, they left LinkedIn in 2014 to form Confluent and commercialize a complete streaming platform while continuing Apache Kafka development.

Business model

Enterprise infrastructure software delivered as usage-based multicloud SaaS, term-licensed/self-managed software with support, managed private-cloud/BYOC deployments, and professional services/education.

Confluent Cloud and WarpStream are primarily usage based; Platform and Private Cloud combine term licenses with post-contract support/maintenance; professional services and education are generally time-and-materials. FY2025 revenue was 96% subscription and 4% services.

Traction

FY2025 total revenue $1.1667b (+21%), subscription revenue $1.1197b (+21%), Cloud revenue $623.6m (+27% and 54% of total), 1,521 customers at $100k+ ARR, $1.4597b RPO, 43% international revenue, $64.3m operating cash flow and 3,241 employees. IBM reported 6,500+ enterprise clients and 40% of Fortune 500 at acquisition close.

Latest developments

IBM completed the acquisition March 17, 2026 and announced day-one integrations with watsonx.data, IBM MQ, webMethods Hybrid Integration and IBM Z. Confluent achieved FedRAMP Moderate in March 2026 and continues current cloud releases, including queues and cluster improvements, under the IBM-owned brand.
