Overview
Guidewheel
Guidewheel provides a FactoryOps platform that gives you full visibility into your manufacturing floor without the need for complex IT integrations. By clipping non-invasive sensors onto the power cords of any machine—regardless of age or make—you can instantly track uptime, downtime, and energy consumption. This real-time data helps you identify bottlenecks, reduce energy waste, and improve overall equipment effectiveness (OEE) across your entire facility.
You can manage your operations through a centralized cloud dashboard that alerts you the moment a machine goes offline or performs outside of its normal range. The platform is designed for production managers and maintenance teams who need to digitize their factory floor quickly. It eliminates manual data collection and provides the factual insights you need to increase production capacity and lower operational costs.
Litmus
Litmus is an all-in-one email optimization platform designed to help you create flawless email experiences for every subscriber. You can build emails from scratch using a specialized code editor, or use visual tools to quickly assemble templates that work across all major platforms. The core strength lies in its automated testing, which lets you preview how your messages look in over 100 email clients and devices before you hit send.
Beyond just testing, you can use the platform to manage your entire email workflow, from collaborative reviews and approvals to advanced post-send analytics. It helps you identify broken links, missing alt text, and slow loading times that might hurt your engagement. Whether you are a solo marketer or part of a large enterprise team, the platform ensures your brand remains consistent and professional in every inbox.
