We are Totam Seeds

Our story

We are an innovative and agile Dutch seed breeding company that develop varieties for high tech greenhouse tomatoes production.

We are founded by growers for growers: we know and understand very well the challenges, difficulties and needs that a grower faces every day.

Since 2020 we are part of the Mitsui Group with greater resources and enthusiasm to bring you new and exciting tomato breeds!

Our history


Founded by Dutch tomato growers

Founded in 2010 by the passion and initiative of three agricultural entrepreneurs, Totam Seeds has grown rapidly over the years. Since our start in 2010 we have been breeding tomatoes for high tech greenhouses.

Prominent becomes main shareholder

Prominent, a large Dutch tomato production organization, becomes main shareholder bringing the knowledge of their growers to provide direction to breeding and evaluating Totam varieties.

Toon van de Ven becomes our R&D Lead bringing over 30 years of breeding experience and determining the development of various successful tomato varieties.

First results of the new breeding program

Over 700 new crosses to offer a diverse collection of tomatoes that brings great resistances and growing power with a clear focus on taste & flavor.

Totam Seeds becomes part of the Mitsui group

We continue our path of growth and development by deploying new resources in R&D, Product Development, and Marketing and Sales. While fully producing under the GSPP protocol we operate in over 10 countries worldwide. We are agile because we are small, flexible and innovative!
