The rapid technology development leads to a growing number of ambitious tech entrepreneurs whose main interest is to tackle social and environmental problems.

Today, more and more startups are launching tech businesses to drive social change around the world.

We have already seen how software technology and 3D printing are revolutionizing society, particularly in healthcare.

When it comes to solving social and environmental challenges, many “social good” businesses are beginning to scale up in the UK, and many of these businesses have a great potential to answer some of the burning problems in our society.

A report on climate change published in early 2014 once again highlighted climate change problems and consequences that are getting more and more difficult to ignore. From big data and open source technologies to mobiles, IoT, and mapping, technology is playing a crucial part in addressing these problems.

There are, for instance, GiveO2 app that tracks carbon footprint as we travel, and PaperKarma, an app focused on cutting paper waste.  More and more organizations, companies and governments are hosting green hackathons while tech companies are building solutions for storage and transmission of the energy to address one of the biggest challenges: clean energy.

The health-tech is still relatively new, but it’s rapidly growing – 2014 saw over $4.1B in venture funding for digital health companies. The future of healthcare technology is promising, from wearables and apps that monitor, track, assess disease risk, and diagnose, to CRM systems that improve communication with patients, and data sharing and storage software.

Educational technology is on the rise, in fact, it has seen an increasing growth in the past few years. The Internet is altering the way we learn, and from social networks and educational platforms to mobile apps, technology has changed how we think about productivity and how we learn.

The need to connect, using and exploring different learning techniques in different fields, draws tech entrepreneurs to create and develop innovative, engaging solutions that are certainly attracting VC firms. Whether we talk about digital and software skills or traditional education, start-ups are revolutionizing education industry.

When it comes to start-ups aimed to solve social and environmental challenges, UK start-ups are in many ways leading the way to innovative solutions.

How?

 BuffaloGrid, which started in 2012, is addressing the problem of the power deficit in the developing world, offering pay-as-you-go phone charging at a network of solar-power hubs.
