Overview

Asserts.ai (Asserts) built observability intelligence for Prometheus and OpenTelemetry environments. Founded by ex-AppDynamics engineers, the product used assertion rules to correlate metrics anomalies with likely root causes — reducing mean time to resolution for platform teams. Grafana Labs acquired Asserts in November 2023 and integrated its contextual intelligence into Grafana Cloud, where it continues as part of the observability stack for Kubernetes and cloud-native deployments.

Why Asserts is interesting

Asserts.ai surfaced root-cause context atop metrics stacks — a16z led seed before Grafana Labs acquired it in 2023, validating assertions-based SRE troubleshooting as a product category.

Product & use cases

Asserts.ai layered contextual intelligence on top of Prometheus and OpenTelemetry metrics. Instead of raw dashboards, SRE teams got assertion-driven alerts that explained why a metric drifted and what downstream services were affected — aimed at cutting investigation time during incidents.

  • Correlating Kubernetes pod restarts with upstream dependency failures
  • Surfacing RCA context during on-call incidents without manual trace stitching
  • Validating SLO burn alerts with pre-built assertion templates for common failure modes

Key facts

  • Acquired by Grafana Labs (Nov 2023): observability intelligence integrated into Grafana Cloud — BusinessWire
  • Seed (Feb 2022): led by a16z — a16z announcement
  • Founders from AppDynamics; product targeted Prometheus/Otel SRE workflows
  • Co-investors: no additional institutional investors disclosed in public sources reviewed 2026-07-25

Competitive landscape

Edge: Asserts focused on opinionated assertions and contextual RCA rather than another metrics store — meeting teams where Prometheus/Otel already ran. Ex-AppDynamics DNA gave credibility on production troubleshooting workflows.

Asserts competed in the crowded observability market by not trying to replace metrics backends. Its bet was that Prometheus/Otel adopters needed contextual intelligence — not more charts. Grafana's acquisition validated the approach: buy the RCA layer rather than rebuild it. Datadog and New Relic offered broader platforms but less native Prometheus assertion workflows.

  • Datadog incumbent

    Full-stack observability with broader APM; Asserts was narrower but deeper on Prometheus-native RCA context.

  • Grafana Labs direct

    Same ecosystem partner that ultimately acquired Asserts — Grafana had dashboards; Asserts added contextual intelligence layer.

  • Honeycomb adjacent

    Event-centric debugging vs. Asserts' metrics-first assertion model; both target faster incident resolution.

Notable stories

  • Asserts was founded by engineers who previously built AppDynamics' application performance monitoring — they applied similar causal reasoning to cloud-native metrics stacks.
  • Grafana announced the acquisition at ObservabilityCON 2023, positioning Asserts as the intelligence layer atop existing Grafana metrics workflows.

FAQs about Asserts

Practical answers founders, operators, and investors typically search for.

Asserts.ai provided contextual observability intelligence for Prometheus and OpenTelemetry — assertion-driven alerts that explained likely root causes of metric anomalies, not just threshold breaches.
Grafana Labs acquired Asserts.ai in November 2023. The technology was integrated into Grafana Cloud's observability stack.
Andreessen Horowitz led the seed round in February 2022. See /fund/andreessen-horowitz for the firm's profile.
Grafana Labs announced the acquisition on November 14, 2023, at its annual ObservabilityCON event.
No — Asserts was acquired by Grafana Labs. Its contextual intelligence capabilities are part of Grafana Cloud.
Platform teams running Prometheus/Otel often had metrics but lacked automated root-cause context. Asserts added assertion rules that correlated anomalies with likely failure paths.
Datadog offers a full-stack observability platform. Asserts was narrower — focused on contextual RCA atop existing Prometheus/Otel deployments rather than replacing the metrics backend.
Asserts was an a16z portfolio exit (acquired by Grafana). We track it for founders and investors mapping devtools and observability M&A.
Asserts and Asserts.ai refer to the same company — the product brand was Asserts.ai; the directory also lists it under id asserts.
Public sources only document a seed round led by a16z before the Grafana acquisition. No Series A was publicly disclosed.
