Invest in a learning center

We propose you to support our learning centers by investing in the BOOKBRIDGE Social Business Fund. We setup a sustainable social business in education run by a dedicated social entrepreneur, making a difference in an emerging economy and paying back your investment over 10 years. At the same time, your investment allows us to run the BOOKBRIDGE Capability Program, an innovative leadership development program, resulting in a sustainable business model for your investment and a profit for our organization. Profits are used to cover all overhead costs and invest in the Fund as well.

Why you should invest in us

With 6 years of experience and a total of 16 investments so far, we have developed a standardized scalable 5 stage process to setup a learning center as a social business. As a social enterprise, we have won prestigious awards, among them Ashoka Fellowship and the Venturekick Competition.

How it works

1. We carefully select an entrepreneur to setup a community based learning center.
2. We identify local investors providing EUR 20t in in-kind matching investments.
3. We run the Capability Program, resulting in a sustainable business model.
4. We pitch the business plan in front of you and the local investor in a real investor pitch.
5. We mentor the entrepreneur and monitor the investment until the is self-sustained.

When to invest

Investments can be made as a donation or a soft loan and will bring you the Honorarium “Founding Funder”. As Founding Funder, you will be a permanent part of the BOOKBRIDGE Legacy and you will be invited to the bi-yearly BridgeBuilder Summit.

Do we also take donations?

You may also support our work with a donation. However, there is a difference to a classic donation: we use your money to invest in a learning center. The center generates revenues and by that way earns back the money you invested. We then use that money to re-invest in a new learning center. By that way, your donation gets recycled again and again, and all for a good cause. In Germany, Switzerland, UK and the US, you will receive a receipt which allows you to deduct your donation from your taxes. For donations in Germany, the bank receipt is sufficient for your tax declaration for donations of up to EUR 200. If you donate more, you will receive a separate receipt from us in due course.
