When investing you are not guaranteed to make money.
Your capital is at risk.

Our aim is to show you investments that match your values

We set out to help people who are trying to make the world a better place through investing. We are the first investment platform to actively rate funds for their positive impact before letting them onto our site.

We exist to help support you in making your investment decision; for you, the planet, and society.

Testing the market

We put all investments through our methodology to see what positive and negative impact they actually make.

Cutting out the noise

We don't regurgitate the marketing talk. We look at what a fund actually does, not just what it says it does.

Simplifying the detail

Our fund details page shows you what the fund does, its past performance, and its impact rating: Gold, Silver, or Bronze.

Take a look for yourself

We show you what's behind your investment

Impact investing is when your investments are made with the intention to generate positive, measurable social and environmental impact alongside a financial return.
‍

Medal ratings

Each fund will be awarded a Gold, Silver, or Bronze medal for how well the fund performs against our test. If a fund doesn't pass the test, it doesn't get a medal, nor will you find it on our website.
‍

Fund filters

One size does not fit all and everyone has differing goals. Whether it is fighting climate change, improving diversity, or avoiding fossil fuels we have filters to help you find the investments you're looking for.

Transparent holdings

Normally you would be only able to see the top ten companies held within your fund. We didn't think that was good enough, so we publish all the holdings - and you can search through them too!

The medals

Every fund on our site is reviewed and independently rated by our research partner 3D Investing (part of Square Mile Investing Consulting & Research) primarily in terms of their contribution through revenue, to the Sustainable Development Goals (SDGs.) The SDGs were developed by the United Nations to solve the world’s greatest problems and are a call to action to end poverty and inequality, protect the planet, and ensure that all people enjoy health, justice and prosperity. We get all of the information, reports, and data about a fund to conduct our analysis, so you don't have to.

More on our methodology...

Gold funds are those where the majority of the fund (over 70%) invested in companies making a positive contribution to the SDGs (through product and /or services). Full integration of ESG risks and opportunities into the investment process (best in class) as well as systematic sustainability reporting. No major detrimental impacts.
Silver funds are those where the majority of the fund (over 50%) is invested in companies making a positive contribution to the SDGs. We would expect to see evidence of sustainability reporting and funds will integrate ESG risk and opportunities as a minimum. In addition, if a fund has a score relative to its benchmark (what it measures its performance against) of 20% or higher it could qualify for a silver if other aspects of the process score highly.
Bronze funds are those funds with a stated intention to invest in companies making a positive contribution to achievement of the SDGs, either through better than average integration of ESG risks and opportunities, or direct stock selection.

How to get started?

It can be difficult to know where to begin when investing - but it doesn't have to be.

Whether you are an experienced investor or doing this for the first time, it's always good to get to grips with the basics.
