We're designing the next generation of light switches and plug sockets, for the world.

by Yasser Khattak in



Light switches and plug sockets have been around for over 100 years, and have hardly changed since. Although few people have tried to reinvent the switch, they've all been really expensive and complicated products that no one really understands how to use.

A few years ago, when I was studying my GCSE's I came up with a better way. So I founded Den, to design the next generation of light switches and plug sockets, for the world. Check out our video to see them in action. 

As you can see below, our products look identical to ordinary switches. You can continue to control them by hand, just like you would an ordinary switch. However, they can also be remotely controlled via our remote, sensor, and smartphone application - in ways that reduce energy consumption, add convenience, and create a safer environment. See examples of uses below




Use Cases

Reducing Energy Consumption

Leaving appliances on standby amounts for up to 16% of our energy bill. In the UK alone, we're wasting £1.3b in energy every year, which is enough to power almost 2.5 million homes.

  •  Turn off all your lights and appliances from the touch of a button, before leaving your home to go to work in the morning, or before going to sleep. 
  • Connect up a sensor to our switches within seconds, without the need of an electrician; meaning your lights will only be on when they need to be. 

Adding Convenience To Your Life

  • You could turn off your light switch from your bed from your smartphone. 
  • You could monitor the amount of energy your home is consuming, in teal time, making sure no energy is being wasted. 
  • You could limit the number of hours a game console will be powered via our plug sockets, by setting cut off times (e.g. 9pm), or daily usage (e.g. 2 hours per day).

Creating a Safer Environment

  • Next time your child stumbles out of bed in the middle of the night on their way to the toilet, Den’s occupancy sensor will automatically activate your lights to keep them safe. 
  • Next time you accidentally leave your hair straighteners or iron on, we can send you a notification to let you know something might be wrong. 
  • Next time your smart smoke alarm detects smoke in the middle of the night, your lights will automatically turn on to guide you out of your home in safety. 
  • Your lights can automatically flick themselves on and off when you're away, giving off the impression your home is occupied to help prevent burglaries. 
  • You can cut off power of low-level plug sockets to prevent the little ones getting shocks if they stick objects inside (we’re working on this). 
  • Elderly/disabled could control their light switches and plug sockets remotely, consequently reducing the amount of movement required.



Accomplishments to Date

  • We're currently in talks with some of the biggest energy companies, homebuilders, and retailers in the UK including British Gas & Berkeley Homes.
  • We've built a great team of 6 engineers and designers who've worked at companies like Google. Product development has been underway over the past few months with several key milestones achieved.
  • Back in 2015 we raised just under £500K on Seedrs, with the most overfunded campaign to have ever funded on Seedrs, and making our founder Yasser Khattak the youngest to ever raise funds on Seedrs. We've also just raised another £500K in 2016.
  • We currently have a patent pending in 10 countries for our switching mechanism.
  • We have received international publicity from the likes of Financial Times, Bloomberg TV, Sky News, BBC Radio, TechCrunch, The Guardian, The Times, Mirror, and lots more platforms.
  • We were nominated for Product Of The Year by London Innovator Awards, making it into the top 5. 
  • We've built an experienced group of investors and advisors, including Julian Nebreda CEO of The AES Corporation Brazil, Francesco Cesarini the Founder of Erlang Solutions, and Darach Ennis Founder and CEO of ThingK.
  • We're currently in talks with various manufacturing partners in preparation for mass production.



Business Model

1) As a manufacturing business we would generate revenues by selling our hardware (physical products).

We aim to supply our products at the prices shown below, however we are currently working with manufacturing partners to confirm these - please note, we will be selling the products direct to homebuilders at much cheaper prices.

  • 1 gang light switch - £19.99 
  • Single plug socket - £19.99 
  • Double plug socket - £24.99 
  • Occupancy Sensors - £24.99 
  • Remotes – £19.99 
  • WiFi Hub - £59.99. Required for our app to work with our switches. 
  • iOS & Android Application - FREE (however we are also currently exploring the opportunities to receive a reoccurring revenue via monthly app subscriptions. E.g. £1 a month).

2) Long term; we plan to generate additional revenues by monetising the data that our products will be capturing via our App. (Google acquired Nest, the smart thermostat for $3.2b; one of the main reasons for this was due to the data that could be captured from their thermostat).


Target Market

1) New homes and buildings, globally.

  • Millions of new homes are being built every year around the world.

2) Existing demand for connected/automated systems. 

  • This is already a proven market, which is growing rapidly - The global market is predicted to generate around $61b in revenue this year, which is expected to grow to around $460b by 2019, meaning there's a huge opportunity.


Distribution & Sales

Supplying directly to the major homebuilders (e.g. Taylor Wimpey, Berkeley Homes, Crest Nicholson, Red Row).

Supplying directly to distributors, wholesalers and retailers (e.g Maplin, Screwfix, B&Q, Homebase, Apple, Currys, TLC).

Working with strategic partners (E.g. British Gas, EON Energy, Nest, Carphone Dixons, O2) who have existing customers bases along with the infrastructure already in place to market and instal the products.

Supplying directly to consumers via our own e-commerce website.

^ We are already in talks with some of the companies mentioned above.
