Were on a mission to help you save water, save money and protect the planet. We help businesses, utilities and homeowners prevent costly leaks, reduce their water consumption and lower their carbon footprint.

We can detect abnormal water use anywhere in your property, notify you via a companion app – and even shut off the water to prevent damage.

Our innovative solution helps property owners, building managers, and insurers protect assets and mitigate the impacts of water-related damage.

The front end of the DPS, the Stamp Free app, enables businesses and private consumers to send letters, parcels or online returns without the need for a postage stamp or printed off postage.

There is also an activated barcoded product - the Shipcode™ for larger volume business customers. Finally the Easycode™ allows customers to return online purchases without the need for a returns label - a mobile phone and a pen is all they need! No need to travel to the post office to buy postage stamps. No need to have a printer to print off postage and laboriously stick it to your mail item. No need for a franking machine or other costly and outdated technology solution. Stamp Free – a digital postage solution for a digital age.

Jobba is a platform that enables businesses of all shapes and sizes to avoid using recruitment agencies and, in essence, build their own. 

 With Jobba youre able to market your vacancies to domain-specific headhunters all over the UK in an instant, and for free, giving your businesses a headhunting capability far greater than any agency or technology can offer. With over a thousand recruiters already signed up whove worked with some of the toughest names in tech, like Expedia, Google, Amazon, Meta, Skyscanner, Microsoft, Stripe, Dyson, Deliveroo, Airbnb and many more, you can be assured that we can source candidates for you quickly and cost-effectively. It doesnt cost anything to use Jobba. You only pay a fee when you hire someone sourced from the platform and what that fee is is up to you - you pick whatever works for your business, from 5-50% of a hires base salary. Candidates have total control and transparency over the info that is submitted about them and to whom its sent to, so when a hiring manager receives a new profile, they know everything is correct and above water. Candidates will also be able to hold recruiters to account via rating systems, incentivising them to work ethically and respectfully. Recruiters will finally earn what they deserve by taking home 80% from every placement fee they generate. This is huge, given that from our research the average commission agency recruiters take home was 15%. So from that £10k fee you just paid an agency, only £1500 went to the recruiter… with us they’ll take home £8K. Offer a recruiter £8k and you can be assured theyll climb mountains to find you what you need. What we’re doing is simple. We’re empowering hiring managers by empowering recruiters. We’re building an ecosystem that cuts out the riffraff and creates an environment where the good flourish and the bad simply wont
