In alpine climbing, the "fast and light" method means ascending without sherpas or a massive support team—just highly skilled climbers moving efficiently. After ten years as a rock climbing guide, Alex McAfee brought this exact philosophy down from the mountains and into the boardroom, co-founding the lean performance advertising agency, Fast and Light, alongside his business partner, Drew.
Operating without a physical office since long before the COVID-19 pandemic made remote work the norm, Fast and Light relies on a boutique core team of just nine people, supplemented by a trusted network of outside specialists. This ultra-lean structure hasn't held the agency back from punching well above its weight. The firm has carved out a unique niche across e-commerce, local businesses, and the entertainment sector, driving campaigns for the hit documentary Fantastic Fungi and spearheading the high-profile relaunch of Spin Magazine.
But navigating today’s fast-paced digital advertising landscape requires more than just human efficiency; it requires the smart integration of artificial intelligence. Speaking on the Main Street AI Podcast, McAfee shared his agency's pragmatic approach to adopting generative AI and Large Language Models (LLMs) into their daily workflows to drive metrics like a 5x return on ad spend and hundreds of new orders.
"Whether it's an LLM or a new employee, you give them a little bit of trust at a time."
Rather than handing over the keys to the kingdom or shying away from the technology entirely, McAfee advocates for a methodical onboarding process for AI tools. By treating an AI agent like a junior staff member, managers can safely test its capabilities, delegate low-stakes tasks, and gradually increase its responsibilities as it proves its reliability.
This measured, incremental trust perfectly mirrors the "fast and light" alpine strategy: utilizing the best available tools to maximize performance while tightly managing risk. As boutique agencies continue to leverage AI to scale their output without inflating their overhead, McAfee’s climbing-inspired approach offers a sustainable blueprint for the future of digital marketing.
