Shauna Griffiths is Founder of SLG Impact. She works with founders, executives, and leadership teams on the brand and agency sides, navigating high-stakes moments — growth, pivots, launches, and inflection points — as an on-demand strategic partner.
Her work centers on helping teams cut through noise, clarify priorities, and move from strategy to action with speed and focus. She advises across:
• Revenue growth
• Go-to-market strategy
• Marketing strategy
• Strategic alliances
• Investment readiness
• Leadership | Maximizing contribution and impact
She also believes leadership is a sport and that the most effective leaders treat their craft the way athletes treat training — with intention, discipline, and a commitment to continuous improvement. She refers to these leaders as Leadership Athletes: people who are actively training to maximize their contribution and impact. That philosophy shapes how she coaches, advises, and builds with clients.
A core part of her work includes leveraging The GC Index®, a data-driven assessment that helps leaders and teams understand their natural energy for impact, optimize how they contribute, and accelerate performance.
With nearly 20 years of experience across both client-side and agency environments, she’s partnered with startups, growth-stage companies, and iconic brands and agencies to drive momentum through growth strategy, strategic storytelling, compelling marketing platforms, and partnership development.
She’s a frequent podcast guest, contributor, speaker, and facilitator, and my insights have been featured in Forbes, SportsBusiness Journal, Shoutout Atlanta, and Bold Journeys.
Recognized as a 2017 Game Changer by SportsBusiness Journal, she also advises Cynisca Cycling. She holds an MBA from Eastern Michigan University and a BA from the University of Michigan, and is a former two-sport Division I collegiate athlete, avid cyclist, and outdoor enthusiast.
