## 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

## Spark Mail

Spark Mail is a smart email client built to reduce information overload. Instead of treating every message the same, it separates what matters from what can wait: Priority flags emails from important contacts, Group by Sender bundles messages, and dedicated Newsletter and Notification inboxes keep automated mail out of your main view. Tools like Gatekeeper, Snooze, Send Later, Set Aside, and Reminders round out the workflow.

AI is woven throughout the experience. An AI Assistant can find, summarize, and act on anything in your inbox; Spark's writing assistant helps you compose better emails faster; Auto-Drafts prepares replies in advance; and built-in translation and summary features help you handle long or multilingual threads. Calendar and meeting notes support keeps scheduling connected to your mail.

Spark is cross-platform — iOS, macOS, Windows, Android, and web — and syncs accounts across devices, supporting IMAP, iCloud, Exchange, Outlook, Yahoo, and Google. It is well established, cited as an Apple Editors' Choice app with more than 21 million users, and offers both personal and team-oriented plans. For teams, it adds shared drafts, private comments, assignment of email ownership, and progress tracking.

**Pricing & Plans:** Freemium with a free tier and paid individual and team plans; a free trial is available so you can evaluate the premium AI and collaboration features before subscribing.

- **Smart Inbox and Priority:** Spark's Smart Inbox and Priority highlight messages from important people and bundle newsletters and notifications so the rest of your inbox stays quiet.
- **AI writing and assistant:** An AI Assistant lets you find, summarize, and take action on anything in your inbox, while an AI writing assistant drafts emails and Auto-Drafts pre-writes replies.
- **Translation and summaries:** Translate incoming messages, get instant summaries of long threads, and quickly grasp the point without reading every line.
- **Team collaboration:** Share drafts, leave private comments, delegate ownership, and track progress on email threads with your colleagues.
- **Focus and scheduling tools:** Gatekeeper blocks unwanted senders, while Snooze, Send Later, Set Aside, and Reminders help you manage time and follow-ups.

**Strengths:** Consolidates multiple email providers in one inbox; Strong AI and focus features that cut through clutter; Robust team collaboration and cross-platform sync

**Limitations:** Full team features require a paid plan; Some AI features are tied to newer Spark versions; Advanced automations have a learning curve
