Who we are

Corporate History

Si Ko is a family company and is named after my father SImeon KOnstantinov. My parents started the business in 2006.

In the beginning, they faced many challenges such as lack of orders, difficult to reach the right customers, as well as working with unsuitable business partners, excessively inflated prices, mainly due to greedy farmers and commission agents.

We hardly even reached the right quality parameters that our customers really need. Each indicator was learned the hard way by the method: “Trial, error.”
Even finding the right manufacturer of the process equipment needed to produce our shelled sunflower seeds – pasteurized, organic and conventional – was a challenge. The optimal quality-price-customer satisfaction ratio took us some time before we reached the point where all customer requirements were satisfied. Suddenly we went from one truck a week to 2 trucks a day. The jump was phenomenal and the team was not prepared for this turnaround. We have started our staff training program and are building a team of professionals. We tried different models and coaching methods until we finally found a system that worked for us.

Now we only work with selected clients who are easy to work with. Being a perfectionist, I always find out what else can be improved, but it is this striving that drives us forward.

The professional execution of orders does not interfere with the personal attitude towards each one. At this point, we are dedicated solely to expanding our product range and business services.
