About CUSP

Gianluca Fonseca

Gianluca Fonseca

Founder & Civil Engineer

At just 16 years old and in 11th grade, Gianluca is an eco-focused Costa Rican civil engineer reshaping how we think about sustainable cities through rigorous technical work and lifestyle advocacy.

From earthquake-proof housing solutions to bike infrastructure advocacy, his work proves that cities don't have to choose between efficiency and sustainability.

The CUSP Philosophy

CUSP operates on a simple principle: sustainable urbanism isn't just about better buildings or greener policies—it's about fundamentally rethinking how infrastructure, lifestyle, and community intersect.

We're not just proposing ideas—we're implementing them. Every initiative creates tangible impact while building a knowledge base others can learn from.

Our approach is both grassroots and systemic: working directly with communities while engaging policymakers to shift the broader conversation about sustainable cities.

Our Approach

Direct Community Action

Working hands-on in underprivileged Costa Rican housing settlements, providing free structural evaluations, earthquake-proofing, and sustainable material solutions that protect both people and the environment.

Policy & Systems Change

Engaging directly with local government to advocate for infrastructure that works—bike paths, green spaces, and pedestrian-first urban design backed by research.

Knowledge Creation

Publishing research, launching a podcast, and building content platforms that make sustainable urbanism accessible and actionable for everyone.

Holistic Integration

Connecting personal wellness through Eco Nutri with broader environmental goals, proving that sustainable living is both individual and collective.
