## Arize AI

Arize is an AI engineering platform built for teams that run generative AI in production. It is split into two products: Arize AX, a managed environment for agent observability, evaluation, and experimentation, and Phoenix, an open-source tracing and evaluation library that teams can self-host when they need full data control. Both rely on OpenInference, the open-source semantic convention for generative AI tracing that the Arize team founded and that is built on OpenTelemetry.

The workflow follows three questions. Observe answers what an agent actually did by capturing every span, trace, and session; Evaluate answers whether quality is improving or regressing using span-level, trace-level, and session-level evals; Learn answers whether a proposed change will help by letting teams test prompts and harnesses before rollout. A datastore for GenAI traces (ADB) keeps data in open formats that connect to warehouses such as BigQuery, Databricks, and Snowflake, and an in-app AI engineering agent named Alyx surfaces issues and drafts review-ready fixes.

The platform integrates with dozens of models, frameworks, and tools, including OpenAI, Anthropic, Google, Amazon Bedrock, LangChain, LangGraph, LlamaIndex, CrewAI, and DSPy. Arize publishes compliance certifications including SOC 2 Type II, ISO 27001, PCI DSS, HIPAA, and GDPR, and supports cloud, hybrid, and self-hosted deployment.

**Pricing & Plans:** Arize uses a paid model with a free entry point: teams can start free or book a demo, while enterprise-scale usage, deployment options, and support are quoted through a contact-sales process. The open-source Phoenix project is free to self-host.

- **End-to-end tracing:** Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
- **Scalable evaluation framework:** Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
- **Alyx AI engineering agent:** An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
- **Phoenix open-source toolkit:** Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.
- **Warehouse-native trace storage:** ADB stores traces in open formats that connect natively to BigQuery, Databricks, or Snowflake for joint analytics with business data.

**Strengths:** Covers the full loop of observe, evaluate, and improve rather than stopping at dashboards; Backed by OpenInference and OpenTelemetry standards, limiting vendor lock-in on trace formats; Strong enterprise posture with SOC 2, ISO 27001, HIPAA, and GDPR coverage plus self-hosting options; Integrates with a very wide set of models, frameworks, and agent SDKs

**Limitations:** Self-serve pricing is not published, so cost requires a sales conversation; The breadth of features can be overwhelming for small teams shipping their first LLM feature; Full value depends on disciplined instrumentation across the whole application

## Quensus

Quensus was founded in 2015 and has grown into a specialist supplier of water risk mitigation technology for commercial and residential property. The core product family centres on LeakNet, now in its second generation, a monitoring platform that pairs flow sensors and sub-metering with AI analytics. The system builds a picture of how water normally behaves in a building and then detects deviations, alerting facilities teams and triggering automatic shut-off where a valve is installed.

The hardware range is broad enough to cover a whole estate: flow sensors and meters, WRAS-approved control valves, leak detection cable, and quick-install Splash Sensors for specific risk points. A lighter product called FlowReporter gives simpler real-time consumption tracking and alerts for sites that do not need full automatic shut-off.

The company positions the system around three outcomes: preventing costly escape-of-water claims and downtime, cutting water bills, and meeting sustainability and compliance obligations. Published use cases cover apartments and high-rise residential, commercial offices, hotels and hospitality, data centres, healthcare, education, retail, heritage buildings, industrial and logistics sites, and construction sites, along with support for BREEAM evidence, NetZero and ESG reporting and Legionella L8 compliance requirements. The company states customers can cut water bills by up to 60% and says leak detection can be insurer-compliant and ROI-driven.

**Pricing & Plans:** Pricing is quoted per project rather than published as standard tiers. Quensus directs prospects to request a quote or make an enquiry, which is typical for hardware plus monitoring deployments sized by building type, number of meters, valves and monitored zones.

- **LeakNet Gen2 monitoring:** Real-time water insights with remote notifications and detailed consumption data, delivering leak prevention and control from wherever you are.
- **Automatic shut-off:** WRAS-approved control valves work with the monitoring platform to cut the water supply when a leak or abnormal flow pattern is detected.
- **Flow sensors and meters:** A range of flow sensors and sub-meters for accurate, reliable measurement across different pipe sizes and fluid applications.
- **Leak detection cable:** Cable that senses the presence of water along its length and can trigger automatic shut-off when paired with the control system.
- **Splash Sensors and FlowReporter:** Quick-to-install point sensors for immediate leak notification, plus a simpler meter for real-time consumption tracking and alerts.

**Strengths:** End-to-end offer spanning sensors, valves, cable and analytics rather than monitoring alone; Founded in 2015 with a decade of deployment experience across many building types; Automatic shut-off capability is a genuine differentiator over alert-only systems; Use cases documented for apartments, data centres, healthcare, retail, heritage and industrial sites

**Limitations:** No transparent online pricing; every deployment requires a quote and site survey; Hardware plus installation makes it suitable for organisations with real property exposure rather than small individual users; Benefits depend heavily on correct meter and valve placement, so installation quality matters; Alert thresholds need tuning per building to avoid noise
