We met in 2019 as seniors at James Madison High School in Brooklyn — two kids with different instincts and a shared restlessness. Robert gravitated towards strategy, operations, and marketing systems. Matthew towards data science, analytics, and technology. Different paths, complementary minds.

In the years that followed, working alongside founders and operators, we kept seeing the same thing: talented people with strong ideas rarely struggle from lack of effort, they struggle from the absence of the systems, infrastructure, and automation required to scale in today’s world.

In March 2026, we founded Arena Cerny Group to be the answer. Robert J. Arena, President and Co-Founder, and Matthew B. Cerny, CEO and Co-Founder. A firm built on a single belief: the right systems and the right strategy unleash growth

We're building the systems that let ambitious businesses operate like enterprises. 

By having strategy, data, and marketing optimization working as one, powered by an AI learning language model shaped to and with your industry, we are building a tool for your business with your ideas in mind. 

Big tech builds for scale and assumes you'll fit. We build for you and let scale follow.

We Listen. Then Build.

Talented people with strong ideas rarely struggle from lack of effort. They struggle from the absence of the systems, infrastructure, and automation required to scale.

Arena Cerny Group was built to close that gap through three pillars working as one:

Strategy to set direction and align the business around what matters most. Data to turn information into decisions and decisions into measurable results. Marketing Optimization to convert attention into customers and customers into growth.

Together, they form the operating foundation that lets founders and teams stop running their business by hand and start running it by design.

This is the bridge between vision and growth. The connection between ambition and the systems that make it real.
