Our Story

Founded in 2013 by Hiroshi Tanaka, JZ ADVISORY GROUP began with a clear vision: to bridge the gap between ambitious business ideas and world-class mobile technology. What started as a small team of three developers working out of a co-working space in San Francisco has since expanded and relocated its headquarters to 3100 NE 48TH STREET 117 FORT LAUDERDALE, FL 33308, growing into a full-service mobile development studio serving clients across the United States and internationally.

Over the past decade, we have delivered more than 200 custom mobile applications across industries including healthcare, fintech, e-commerce, education, and enterprise solutions. Our commitment to quality, transparency, and measurable results has earned us long-term partnerships with clients who trust us to bring their most critical projects to life.

Our Mission

Our mission is to empower businesses with mobile technology that is intuitive, scalable, and built to last. We believe that a great mobile application is more than just code — it is a strategic tool that connects companies with their customers, streamlines operations, and opens new revenue opportunities.

Every project we undertake begins with understanding the unique challenges and goals of our clients. We do not believe in one-size-fits-all solutions. From initial strategy and design through development, testing, and post-launch support, we work as an extension of your team to ensure every deliverable meets the highest standards of quality and performance.

Our Core Values

Transparency

We operate with full transparency in our business practices, pricing, communication, and legal standing. Our clients always know exactly who they are working with.

Client-First Approach

Your goals are our goals. We invest time understanding your business before writing a single line of code, ensuring the final product delivers tangible value.

Technical Excellence

We follow industry best practices in software architecture, security, testing, and deployment. Our code is clean, maintainable, and built for long-term scalability.

What We Do

JZ ADVISORY GROUP provides end-to-end custom mobile application development services. Our core offerings include:

iOS & Android Development — Native and cross-platform applications built with Swift, Kotlin, React Native, and Flutter, tailored to your specific business requirements and user experience goals.
