Close funding

sensible & profitable

For investors who want to do good with their money, we create investment opportunities that are not only financially profitable but also environmentally and socially sustainable. In this way, investors earn attractive interest with a clear conscience.

simple & secure

bettervest is a platform where project owners and investors meet. By pooling many individual sums of money, loans are created here that are used for good causes and yield returns.


sustainable & effective

Many effective projects are waiting to be financed. For example, those that save resources, reduce emissions and improve the quality of life for many people. We close this financing gap.

The pioneers in

bettervest was launched in 2012 to finance energy efficiency projects run by citizens. The reason: energy efficiency saves money, conserves resources and reduces CO2 emissions. This should benefit not only large corporations, but also private individuals.

Futurologist Patrick Mijnals presented this idea at a Start-Up Weekend, where he convinced his first future comrades-in-arms. In the following weeks, Patrick recruited further co-founders with different competences. Soon an idea became a business model.

Since the launch of the first project in 2013, a lot has happened. In the meantime, we have outgrown the infancy of a start-up and our horizon has expanded significantly: We finance sustainable and future-oriented projects worldwide with a focus on Africa and Germany – whether biological wastewater treatment in Kenya, solar mini-grids in India or energy-efficient building renovations in Germany. We have remained true to our mission: To shape a more climate-friendly and social economy and society in the long term./p>
