One home. One intelligence.

Your home is currently a collection of disconnected apps. Keld unifies them into a single, private ecosystem.

1

Integrate

We connect your disparate hardware—solar, security, sensors—into one local hub.

2

Harmonize

Keld learns your rhythms privately, processing data locally without relying on the cloud.

3

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.

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.

The Architect

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.
