Cribl, an AI platform for telemetry data, acquired Tero on November 10, 2026. Tero builds an intelligence layer for observability data. Tero's co-founders and their engineering team will join Cribl.
Leadership joins Cribl
Ben Johnson, Adam Cohen, and Nihar Singhal are joining Cribl. Johnson will serve as vice president of observability. He previously co-founded Timber, which Datadog acquired in 2021.
Third acquisition in four months
Tero is Cribl's third acquisition in four months. The company bought CardinalOps in July and Radiant Security's AI SOC technology in August. The Tero deal brings a team with deep market knowledge and customer credibility.
What Tero brings
Tero's technology measures how much telemetry is waste. It pinpoints low-value data across observability tools and lets engineers fix it in the tools they already use. At Cribl, the team will lead work on host monitoring, application performance monitoring, federated observability, and AI-native observability.
The combined capabilities will sit on Cribl's open platform for collecting, routing, and optimizing telemetry. Cribl is extending its market toward first-party observability and security capabilities. The work will support engineers and the AI agents working alongside them.
