OUR STORY
Built from a 25-year friendship and a shared opportunity.
Ray Hallak and Kurt Castle brought their experience together to create Apex Microbials after recognizing a gap between promising microbial biology and practical agricultural products.
HOW APEX STARTED
A long friendship became a focused agricultural company.
More than 25 years of trust
Ray and Kurt built a long-standing friendship before joining forces professionally. That trust became the foundation for Apex.
A missing link in the microbial world
They saw the need for agricultural microbial products that could move beyond promising biology and become practical, clearly defined products.
Testing, refining, and building Apex
After extensive testing and iteration, they formed Apex Microbials to develop focused product families and bring them toward responsible commercialization.
PARTNERSHIP + HISTORY
Experience from earlier microbial work helped shape the direction.
Castle's Labs is a partner in Apex Microbials. Earlier work under the Microbyl name helped inform the agricultural opportunity Apex is now developing through Worm Tea Composter, Growth & Vitality, The Deodorizer, Super Tea, and a biochar treated with the Apex microbial blend.
