Digital transformation, delivered on the plant floor
Industries are constantly evolving, with digitalisation at the forefront of this transformation. Cloud IIoT (Industrial Internet of Things) and Industry 4.0 are key drivers, enabling the integration of advanced digital technologies into industrial processes. Listo helps you get there with solutions that scale from proof of concept to full roll-out.
Consultation to achieve big goals
Comprehensive consultation services to help your business set and achieve its industrial automation goals — from the first site survey to a phased roll-out plan.
Training for successful implementation
Our training programmes make sure your engineers and operators are equipped to get the most from every solution we deliver.
Customisable solutions for your needs
Every plant is different. Our hardware and software are scalable and adaptable, so the system fits your operational goals rather than the other way round.
Your whole factory, one screen.
AGAD Portal is our industrial IIoT platform, designed and built in-house from the ground up. It collects data from every source on a site — automatically or manually, and from other cloud providers — and presents it in a single product viewable from anywhere.
- Production, energy, maintenance and quality data side by side, live and historic
- Connect the machines, meters and systems you already have
- No per-user charges — pricing is based on data points, not seats
- Certified to ISO/IEC 27001:2022, with the platform itself in scope
