At the International Youth Foundation, we brought in Simon to help us re-develop our entire brand architecture—mission, vision, values, messaging, the whole kit and caboodle. Simon worked hard and fast, balancing creativity and efficiency at every turn. The result? Our new brand architecture was enthusiastically embraced by staff, sailed through the board of directors’ review, and equipped our marketing and communications team with a package of turn-key assets to activate immediately.

“Since 1984, REEF has been about having fun, celebrating surf and beach culture, and offering the best sandals in the world. We always knew we stood for something even bigger, had values that went beyond making product, and wanted to make a more meaningful impact on the world at large, but we found ourselves challenged to unpack our “why” and articulate a clear purpose. Simon led us through a highly strategic, intense and immersive process that challenged us to dig deep, throw out any sacred cows, work together across all departments, identify a white space, and drive toward a brand purpose, position, and story framework to unlock our true growth potential. We have found that the process effectively links corporate citizenship with profitability, and we are beyond happy with the investment we made.”

How Simon partners you...

Simon works with global corporations, PE and venture firms, and high-growth startups as a strategic adviser at a moment when leadership judgment and coherence have never mattered more. Helping firms strengthen the alignment between strategy, culture, leadership behavior, and market narrative before misalignment quietly erodes enterprise value.

Working closely with leadership teams, investment partners, and portfolio companies, he surfaces where fractures form when capital, speed, and disruption collide, rebuilding coherence so that decisions, execution, and identity reinforce one another under pressure.

Drawing on experience across organizations at every stage and scale, he brings that hard-won perspective to the AI frontier, where automation and speed are reshaping trust and organizational design, helping leaders translate innovation, purpose, and culture into durable performance in an unpredictable world.
