Marissa Brassfield is Ridiculously Efficient®. She's the vital bridge between "make it up" and "make it real" — the integration specialist that visionary entrepreneurs in 20+ countries trust to transform bold ideas into thriving business ecosystems.
The Force for Good
Described by clients as a "lynchpin," "force multiplier," and "goddess of operations," Marissa is the gyroscope that keeps visionary entrepreneurs and their teams upright during periods of intense change. Her unique talent lies in making complex visions remarkably simple to execute while ensuring the human element remains at the center.
Since 2007, Marissa has challenged the status quo of burnout culture, toxic teams, and prioritizing money over relationships – with love, efficiency, creativity and influence.
🚀 Turning Ideas Into Action
Marissa has cultivated relationships, created thought leadership strategies, launched products, designed experiences, and recruited small teams that have collectively driven hundreds of millions of dollars in attributable revenue for Fortune 100 executives, nonprofits, and global leaders.
Her stages have been the intellectual playground of luminaries like Ray Kurzweil, Tony Robbins, Arianna Huffington, and Tom Bilyeu, alongside executives from Microsoft, Uber, HTC China, and IBM Watson.
All as an independent contractor working remotely (back when it was still weird to work from home).
🧠 Curating & Contextualizing Wisdom
As a high-performance writer and brand marketer, Marissa has published over 15,000 online articles under her name and ghostwritten several thousand more for entrepreneurs across four continents.
While working with Peter Diamandis, she created an experimental news digest called Abundance Insider that gathered the week's top technological breakthroughs. The concise, scannable format and thoughtful analysis made it an instant hit, reaching over 300,000 subscribers weekly. Diamandis would later incubate a startup using AI to automate this curation work (now known as daily.ai), with Marissa as a founding shareholder and advisor.
🧭 Navigating Unprecedented Change
In 2019, Marissa architected a significant work-life reinvention and renegotiated all her significant personal and professional relationships.
Never again would work come before her values, the quality of her marriage, or her own wellness.
The universe had a surprise in store: a pregnancy, a global pandemic, and an overnight shift toward remote work.
