In Series 10, Episode #90, I sit down with Ciaran Marron, founder and CEO of Activ8 Solar Energies. Ciaran shares his incredible journey of starting from a makeshift office in a rented house's back bedroom to building a large-scale solar energy business with over 300 staff and a turnover of 70 million euros. He discusses overcoming early challenges like cash flow issues, adapting to market changes, and scaling operations across Ireland, the UK, and Europe. Ciaran also touches on his risky yet successful ventures, including landing a crucial deal with SSE Arena and forging a strategic partnership with SSE Airtricity.
