About us

Isolagra is a successfully operated family business in the 2nd generation. With pride we look back on our founding in 1986. In our 30 year history countless projects have been creating a proven track record. We are Value Investors, while we see ourselves as long-term and strategic partners.


The volatility of the markets is not as a risk but an opportunity. We invest heavily and do not think in quarters but in generations.





One of our first projects, a greenhouse, was established on a sight of about 30.000 square meter in the desert of Saudi-Arabia.

Isolagra Value Investing

Value Investing

Our investment philosophy follows consistently the Value Investing style of Warren Buffett and Charlie Munger.
Therefore, we are investing in undervalued quality companies with a margin of safety. This gives us the advantage to remain calm even in difficult situations. Our selection of investments can be described accordingly to Buffett`s characteristics as follows: "We only invest in a company if we
(1)   understand the company's business,
(2)   the long-term prospects of the company are good (proven and long-term profitability, good returns on
 invested capital, little or  no debt, attractive businessmodel)
(3)   the company is managed by competent and honest managers and
(4)   is very attractively valued. "

Alternative Investments

Isolagra sees alternative investments as a long-term addition to the portfolio. We focus primarily on investments which are uncorrelated with the market. Again, it always comes back to inefficiencies, which will allow us to achieve attractive returns.
