The integrated
smart home.
Everything connected. Everything simple. Unified intelligence for your home's security, climate and care.

One home. One intelligence.
Your home is currently a collection of disconnected apps. Keld unifies them into a single, private ecosystem.
Integrate
We connect your disparate hardware—solar, security, sensors—into one local hub.
Harmonize
Keld learns your rhythms privately, processing data locally without relying on the cloud.
Automate
Your home anticipates your needs. Lighting, climate and security adjust seamlessly to your daily rhythm.
Intelligent Energy
Your home buys energy when it's cheap and runs off batteries when it's expensive. A greener footprint and lower bills, automated entirely in the background.
Local & Private
Your sensitive data stays on your premises, not a server. This means instant response times and total privacy. What happens at home, stays at home.
Guardian Care
Empower independent living. We privately detect safety anomalies and alert you when it matters, without invasive cameras.
Energy that pays for itself.
Smart synchronization of your Solar, Battery, and EV.
- Smart Tariff Switching: We automatically buy power when it's cheapest.
- Solar Optimization: Prioritizes using your own generated power over the grid.
- Smart EV Charging: Charges your car ready for departure, at the lowest possible cost.
The Keld Offset
Our goal is that your energy savings cover your subscription cost.
Live Analysis

*Projected savings based on average consumption.
Private Security.
Protecting your home with presence, not just alarms.
Occupancy Simulation
Lights and blinds mimic your actual habits, not just a timer. It looks like you're home, even when you're in Tuscany.
Unified Alarm
Intelligent motion detection that filters out pets but catches intruders. Distinguishes between a fox and a footstep. Instant alerts to your phone.
Fire & Escape
Integration with smoke alarms to automatically illuminate escape routes and unlock exits in an emergency.
PRIVACY FIRST: Footage is stored locally. We monitor system diagnostics and stability to ensure uptime, but never access video or audio without your permission.
Care that respects their dignity.
Peace of mind for you. Uninterrupted independence for them.
We believe that safety shouldn't come at the cost of privacy. Keld's Guardian Care system uses subtle environmental sensors—not cameras—to learn the natural rhythm of a home. It detects anomalies intelligently, alerting you only when it truly matters, so your loved ones can live freely while you rest easy.
- No Cameras
- Activity Rhythms
- Temperature & Comfort

Engineered for reliability.
Built for life.
Modern smart homes are often a collection of disconnected gadgets. I treat them as critical infrastructure.
My background is in building mission-critical systems where downtime is not an option and security is paramount. I founded Keld to bring that same level of engineering rigour to the home—building an ecosystem that is robust, private, and works every single time.
