Arize AX

Arize AI is the continual learning and AI engineering platform for observing, evaluating, and improving AI agents and LLM applications across development and production. Trusted by leading AI startups, 25% of Fortune 100 companies, and 150+ enterprises, including Uber, DoorDash, Reddit, and Atlassian. Traditional APM tells teams whether an application is fast and available. Arize goes further, showing whether an AI system behaved as intended and delivered a high-quality, trustworthy response. OBSERVE how your agents actually behave. Trace every step of a session, including prompts, tool calls, retrievals, chains, and multi-agent swarms. ADB, Arize’s purpose-built datastore, unifies traces and eval data in open formats. Its elastic architecture supports real-time streaming and high-volume querying while allowing teams to access their data from existing tools and warehouses without exporting or duplicating it. EVALUATE agent quality using those same traces. Run LLM-as-a-judge, code-based, and Agent-as-a-Judge evaluations to assess quality and score outcomes. Run offline evaluations on datasets to test and compare changes before release, and online evaluations on production traces to monitor quality and detect regressions over time. IMPROVE CONTINUOUSLY by turning production feedback into an agent improvement loop. Signal, Arize’s always-on Agent SRE, continuously reviews production traces to surface emerging issues and failure patterns. Connect to a repository and Arize managed agents can investigate issues and propose fixes as pull requests for human review. Engineers can also use Arize Skills to investigate traces, create datasets and evals, and run experiments from Cursor, Claude Code, Codex, and other coding agents. Arize AI, the team behind OpenInference, provides open, portable instrumentation built on OpenTelemetry, with integrations across more than 40+ models, frameworks, and tools. Arize meets production-grade security and compliance requirements, including SOC 2 Type II, ISO 27001, HIPAA, and GDPR. The team also maintains Phoenix, the open-source AI observability and evaluation platform used by AI engineers worldwide.

Monte Carlo

Monte Carlo is the agent trust platform, trusted by Nasdaq, Cisco, PepsiCo, and hundreds of enterprise organizations worldwide. Founded in 2019 and backed by leading investors, Monte Carlo pioneered data observability and has expanded into the full AI reliability stack. We're consistently ranked #1 in data observability on G2 — and we're built for what comes next. As enterprises scale from dozens to thousands of AI agents across mission-critical use cases, Monte Carlo monitors, troubleshoots, and improves both those agents and the underlying data powering them. Our platform covers the full trust stack — from the data pipelines feeding agents, to the context they retrieve, the decisions they make, and the outputs they produce — across four trust dimensions: context quality, performance, behavior, and outputs. Only Monte Carlo closes the full trust loop across both data and AI, and we meet enterprises wherever they are on the spectrum from human-guided oversight to fully autonomous operations. With 100+ integrations across Snowflake, Databricks, and the rest of your stack, you get full coverage without ripping anything out. Traditional monitoring tools stop at the pipeline or cover only one dimension of reliability — leaving teams to manually investigate, diagnose, and fix failures across disconnected tools. Monte Carlo closes that gap. Teams using Monte Carlo dramatically reduce time to detect and resolve data and AI incidents, scale monitoring coverage without scaling headcount, and build the internal trust that turns AI investments into real business outcomes. If your organization is serious enough about AI to put it in front of customers, executives, and critical decisions — Monte Carlo is the foundation it needs.

Acceldata

Acceldata is the Data and AI platform for Autonomous Enterprise. Large enterprises need uniform data access, compute capabilities and governance to run analytics and deploy agents across their hybrid infrastructure. But most enterprise data platforms were built on the assumption that data would eventually centralize into a single warehouse or lakehouse. In practice, large enterprises operate four or more data platforms simultaneously, with data distributed across cloud providers, on-premises systems, and regulated environments that cannot move data across borders. Acceldata addresses this by bringing compute to wherever data already resides, rather than forcing data to move to the compute engine. Acceldata supports every stage of the data lifecycle, on any platform, bringing compute to where the data lives and ensuring data trust by unifying data quality, governance and observability into an intelligent, AI-driven fabric. Trusted by Fortune 500 companies worldwide, Acceldata empowers businesses to unlock the full potential of their data in the AI era. Key capabilities include: 1. Data and AI Observability: End-to-end monitoring of data pipelines, data quality, AI agent behavior, and LLM outputs. Includes anomaly detection, data lineage, reconciliation, and alert management across environments. 2. Agentic Data Management (ADM): Deploys autonomous agents to automate data quality monitoring, pipeline operations, catalog management, and incident response across distributed data estates. 3. Agentic Data Engineering (ADE): Builds, orchestrates, and runs data pipelines using intelligent agents that automate pipeline creation, federated querying, and job management. 4. Data Warehousing: Executes queries in-place across lakehouses and warehouses using a Velox-accelerated engine, supporting open formats including Apache Iceberg, Delta Lake, Hudi, and Parquet with no vendor lock-in. 5. Data Platform Modernization: Provides phased migration paths for enterprises running Hadoop or Cloudera infrastructure, with in-place, sidecar, and forklift migration options built on an open-source foundation. Acceldata is designed for large enterprises in financial services, life sciences, telecommunications, manufacturing, retail, and insurance, particularly organizations operating regulated data environments where governance and data residency requirements prevent full cloud migration. The platform integrates with Snowflake, Databricks, AWS, Azure, GCP, and major open-source data frameworks.
