Macklin Hartley

I help top-notch organisations by bringing together crystal-clear objectives, a culture of support, streamlined operations, and adaptable technology. I'm a firm believer in small, dynamic teams that embrace autonomy and take responsibility, prioritising outcomes over specific solutions. Above all, I believe in pursuing something you're passionate about alongside individuals you genuinely admire and respect. With a wide array of technology interests, I thrive on embracing new challenges.
