Miami's Own Ariel Dominguez is Rewriting the Rules of AI and Healthcare

[July 15, 2026] – [Miami, FL]: ​ Miami has always had heat. But right now, the most electric energy in this city isn't on South Beach — it's inside the servers and boardrooms of a homegrown tech ecosystem that's putting the Magic City on the global AI map. At the center of it all is Ariel Dominguez, CEO of Theo Vex and the visionary force behind Open Insurance — a Miami-headquartered AI research lab quietly building the infrastructure powering the future of insurance, healthcare, and enterprise productivity.

In a city that has transformed itself into one of the most formidable tech hubs in the Western Hemisphere, Dominguez represents something Miami can truly call its own: a serial entrepreneur with 20-plus years in healthcare and technology, four companies built from the ground up, more than $100 million raised, and organizations valued at over $200 million — all while staying true to the 305.

"I wrote my first lines of code at 15," said Dominguez. "Nobody told me to. I just wanted to build something. That feeling never went away."

Theo Vex & Open Insurance: Miami's AI Research Lab

At the corporate level, Theo Vex serves as the umbrella entity for a family of AI-powered products and platforms developed under the Open Insurance research lab. The company's mission is singular and audacious: to build the models, tools, and operating system that power modern insurance and healthcare — and to do it from Miami.

Open Insurance is not a traditional insurtech company. It is a full-stack AI research lab that builds orchestration models purpose-built for insurance — from intent classification and multi-model routing to claims orchestration and policy understanding. Every product in the Theo Vex ecosystem runs on the same foundational model layer, creating a unified intelligence engine that the industry has never seen before.

HiTheo: One API. Ten Engines. Infinite Possibility.

The flagship AI product is Theo — a groundbreaking orchestration AI accessible via HiTheo (hitheo.ai), offering ten intelligent engines through a single API key. Theo automatically classifies the intent of any prompt, routes it to the optimal engine, handles failover with triple redundancy, and streams the response — all in under a millisecond on its fast path.

Theo's specialized engines include:

For healthcare organizations and insurance carriers, HiTheo delivers a transformative capability: rather than managing dozens of AI vendor relationships, they access everything through a single SDK. The impact on operational costs, speed-to-insight, and technology agility is immense — and this is built right here in Miami.

OpenCharts: The AI-Native Productivity Platform That Changes How Teams Think

Dominguez calls OpenCharts his passion project — and it shows. OpenCharts (opencharts.com) is the first truly AI-native productivity platform, merging flowcharts, whiteboards, notes, presentations, podcasts, code canvases, and AI-powered creation into one seamless workspace. Think of it as the tool every founder, executive, and operator wished they had — built by someone who actually ran those organizations.

"This is the tool I wished I had at every company I ever ran," Dominguez explained. "My goal is simple. I want to help people become better versions of themselves. Not with fluff, but with software that respects how the human brain works."

Powered by Theo AI, OpenCharts gives users over 120 templates, AI agents that build complex diagrams from a simple text prompt or uploaded PDF, and real-time collaboration tools. For Miami's exploding ecosystem of startups, healthcare companies, law firms, and financial services organizations, OpenCharts delivers enterprise-grade productivity in one unified workspace.

Mark Your Calendars: Ariel Dominguez at ACA WAY 2026

📍 ​ Hilton Downtown Miami ​ | ​ September 23–24, 2026

ACA WAY 2026 is one of the most consequential gatherings in the healthcare insurance calendar — bringing together agents, business motivators, carriers, major insurance companies, and the AI tech industry under one roof. This September, all of them will converge at the Hilton Downtown Miami, and Ariel Dominguez will be among the most anticipated voices in the room.

Dominguez will take the stage on September 23 and 24 to present the full Theo Vex product suite directly to health carriers and industry leaders, making the case for why staying ahead of the AI revolution is not optional — it is existential. For an audience navigating an increasingly complex regulatory, actuarial, and consumer-expectation landscape, his presentation will cut through the noise and demonstrate precisely how AI orchestration transforms claims processing, member engagement, policy intelligence, and enterprise operations in ways the industry has never seen before.

"The carriers who understand AI today will lead the industry tomorrow," said Dominguez. "And Miami is going to be where that story gets told."

The conversation will continue with Code & Care, a forward-looking panel featuring Dr. Katrina Rosseini, Managing Partner at Queens GMBT, and Matthew Versaggi, MS, MBA, former White House Presidential Innovation Fellow in AI and Senior Director of Artificial Intelligence and Distinguished Engineer with Optum, UnitedHealth Group. Together, they will explore where AI is taking the healthcare ecosystem, how it is reshaping care delivery and business operations, and why organizations that fail to adapt risk being left behind. This discussion will give attendees insight into what is next and why staying ahead of the AI revolution is essential for future success.

Why Miami. Why Now.

In the last five years, Miami has emerged as one of the most consequential cities in the global technology ecosystem. From the influx of venture capital and founders fleeing the coasts, to the Mayor's famous "How can I help?" tweet that opened the floodgates, Miami has staked its claim as a city that builds.

Ariel Dominguez didn't arrive from San Francisco or New York. He is Miami. And the company he has built — a vertically integrated AI research lab with products spanning healthcare, insurance, productivity, and enterprise infrastructure — is exactly the kind of flagship story this city's tech community has been waiting for.

"I am a builder," Dominguez said simply. "Always have been. And I am just getting started."
