Early Life & Influences
Growing up in Sète, a sleepy port town, Fidji’s earliest memories smell of salt air and feel of nets hauling in each morning’s haul. Her family, steeped in generations of fishermen, taught her dignity in hard work—no shortcuts, no shortcuts.
She was the first in her family to graduate from high school. Witnessing the rhythm of the tides and the economy of her hometown gave her respect for steady effort and cyclic change—traits that would define her career.
Family & Personal Background
Her father and grandfather were fishermen. That upbringing instilled teamwork, endurance, and accountability.
Later, her diagnosed postural tachycardia syndrome (POTS)—a chronic condition causing dizziness—gave new meaning to resilience. Simo adapted by bringing a recliner to meetings rather than hiding her illness. That decision later fueled her founding of the Metrodora Institute, named after a 5th‑century woman physician, dedicated to neuroimmune disorders.
She’s married to French‑engineer‑turned‑chocolatier Rémy Miralles, and they have a daughter. Simo splits time between Los Altos and Palo Alto, CA.
Education & Academic Story
Destined for excellence, Simo attended HEC Paris, one of Europe’s top business schools. In her final year, she went to UCLA Anderson, bridging Europe and Silicon Valley.
Despite academic recognition, she never lost her humble roots. No thesis on tech trends, but boardroom strategies, grit, and a vision of democratizing opportunity.
Personality, Passions & Habits
Simo is a pragmatic optimist—she loves tech not for code or hype, but for real human impact. She hates standing meetings so much she canceled 100,000 hours of them at Instacart .
She retains her French accent proudly, reportedly refused advice to disguise it at Facebook—preferring authenticity over assimilation. She balances ambition with kindness, efficiency with curiosity—using empathy as a leadership tool.
Love Life & Relationships
Simo keeps love life low-key. Married to Rémy Miralles, they share a daughter and balance high-demand careers with home life in Palo Alto. While not public figures, their bond became stronger thanks to collective resilience through Simo’s chronic illness and startup-level challenges
