About Mr. Fox, LLC

Who We Are

Mr. Fox, LLC is a Chicago-based software development company founded by Anthony Guzzardo. The company builds mobile apps, web applications, and backend systems for startups and businesses.

Mr. Fox isn't an agency. It's a product company that takes on select client work. This means the team understands what it takes to ship software that people actually use.

What We Build

Full-stack development across the board:

• Mobile: Native iOS and Android apps (SwiftUI, Kotlin, Jetpack Compose)
• Backend: Swift Vapor, Node.js, PostgreSQL, RESTful APIs
• Web: Astro, React, Next.js, TypeScript
• Infrastructure: AWS deployment (ECS, RDS, CloudWatch), scalable systems

Our Flagship Product

Rangley is a location-based social meetup app for iOS. It's live on the App Store right now.

The Founder

Anthony Guzzardo graduated from DePaul University in 2023 with a computer science degree. Before founding Mr. Fox, he worked at EL3 Tech and Treevah, building software across multiple industries.

He's technical, direct, and moves fast. No pointless meetings, no overengineered solutions. Just solid code and working products.

Work With Us

Mr. Fox works with founders and companies on early-stage products, mobile apps, and technical architecture. The approach is straightforward: understand what needs to be built, build it, and get it in front of users.

If you're building something real and need a technical partner who can execute quickly, reach out.

Mr. Fox, LLC is an independent software studio based in Chicago. We build products and solve technical problems.

To whom much is given, much is expected.
