Background

Asirius' Foundations

I founded Asirius in 2019 to help companies transform and grow — whether by bringing clarity and expertise, or by helping restructure and refocus organisations. With a background in automotive consultancy (including eight years at Ricardo) and in building businesses across sectors, I bring a proven commercial and strategic mindset. My work has led to multiple successes, most notably the establishment and growth of hofer powertrain UK Ltd.

William Hartley

In 2013, I set up and grew hofer powertrain UK, developing it into a leading Tier 1 automotive powertrain supplier with more than 100 employees and UK-based technical and production sites. I had complete responsibility for growth, vision, and strategy, as well as implementation and day-to-day management.

Reflecting on my time as Managing Director, the hofer Group CTO said:

“William’s drive, enthusiasm, tenacity and exceptional business acumen led to the swift expansion of the UK operation and ultimately led to one of the largest entities within the hofer Group with the most significant and Group transformational projects. His success at establishing and growing hofer powertrain UK directly contributed to quadrupling of the Group size over the seven years as well as leading to joint ventures with significant other parties.”

The knowledge and experience I gained through founding and leading businesses — most notably hofer powertrain UK — forms the foundation of the work I deliver today.
