Ariel Dominguez
Chief Executive Officer
Sets the thesis the whole company runs on: regulated industries do not need another point tool, they need an intelligence layer they are allowed to own.
The OpenCharts founder story
OpenCharts started with a flowchart that wouldn't draw itself. Below is the same story the interactive canvas above tells, in plain text.
Four people, one stubborn problem
OpenCharts did not start with a growth plan. It started with four people who had spent years inside industries where the software is always almost right, and never quite allowed to touch the part that matters.
Ariel, Tony, Alexandr, and Daniel
Ariel Dominguez set the thesis. Tony Feijoo had already built one of the largest insurance field organizations in the country. Alexandr Vinocurov runs execution. Daniel Diaz owns the legal guardrails. Four people who had each seen the problem from a different side of the same table.
Years inside healthcare and insurance
This is the part that shaped everything. Healthcare and insurance are not hard because they are complicated. They are hard because a wrong answer has a consequence, and because a data policy is a contract somebody signed. Every product decision here comes from that room.
So they started TheoVex
TheoVex is an AI research lab for highly regulated industries. A customizable application layer over an inference layer, so a hospital or a carrier can build its own compliant tooling instead of renting someone else's. OpenCharts is one of the products that runs on it.
Could an existing tool do this?
The honest first question, asked before writing a line of code. We went looking for something to buy. Two answers came back, and neither of them was yes.
Everything was rented
The deck tool, the doc tool, the board, the sheet, the site builder, the video editor. Eleven subscriptions holding one company's thinking, none of which you own, all of which stop being yours the month you stop paying.
Everything read your work
Perfectly fine for a mood board. Not fine for a patient chart, a claim file, or a matter you are professionally responsible for. In a regulated room, an unclear data policy is the same as a no.
So we built the layer ourselves
If the thing you need does not exist and cannot be bought, the only honest option left is to build it — including the model family underneath it. ARCA is ours. That is the difference between a product and a wrapper.
One surface, four jobs
The insight that made OpenCharts a single canvas instead of a suite. The deck, the doc, the board, the sheet, and the site were never separate problems. They were one problem, split across a subscription stack.
Product
Charts, boards, notes, and decks you can open and start drawing inside in ten seconds. No onboarding call, no implementation partner, no quarter-long rollout.
Platform
Sheets, code, video, and files living side by side in one workspace, so a thought does not have to be re-typed every time it changes shape.
Protocol
Open APIs, skills, and agents, so the rest of your stack can reach in. A layer you build on rather than a box you work inside.
Process
Theo keeps working when you close the laptop — and reports back in language a person can actually check, which is the only version of automation a regulated team is allowed to trust.
That is OpenCharts
The creation surface where a person and Theo build something together. Owned by TheoVex, built alongside Theo and the Hitheo.ai orchestration API, and shipped so the strictest customer can use it first.
Your work stays yours
We do not train on customer data. You keep ownership and control of everything you put in, and everything you make is exportable on the way out.
One surface, not eleven
Every artifact on a single canvas, so the thinking does not get lost in the gap between tools. That gap was the original problem.
Built for the strictest room
Starting in healthcare and insurance is what makes the product safe to use everywhere else. Build for the room with the real consequences and the easy rooms take care of themselves.
The goal
Give the work back to the people doing it. Not to replace the clinician, the agent, or the attorney, but to hand them a surface where thinking and shipping finally happen in the same place.
Open your workspace
That is the whole story. The next part is yours — open a blank canvas and build something on it.

- 01 — Act I
It started with four people
Not a garage story. Ariel, Tony, Alexandr, and Daniel had each spent years inside healthcare and insurance — the two industries where the software is always almost right, and never quite allowed to touch the part that matters.
- 02 — Act I
So they started TheoVex
An AI research lab for highly regulated industries: a customizable application layer over an inference layer, so a hospital or a carrier can build its own compliant tooling instead of renting somebody else's.
- 03 — Act II
Everything on the market failed the same two tests
We went looking for something to buy first. What we found was eleven subscriptions holding one company's thinking, none of which you own — and terms that were fine for a mood board and completely unusable for a patient chart.
- 04 — Act II
So we built the layer ourselves
Including the model family underneath it. ARCA is ours. When the thing you need does not exist and cannot be bought, building it is the only honest option left.
- 05 — Act III
One surface, four jobs
The deck, the doc, the board, the sheet, and the site were never separate problems. They were one problem split across a subscription stack — so OpenCharts is a product, a platform, a protocol, and a process on a single canvas.
- 06 — Act III
That is OpenCharts
One of several products on the TheoVex platform, built alongside Theo and the Hitheo.ai orchestration API. Your work stays yours, it lives on one surface, and it was built for the strictest room first.
- 07 — The goal
Give the work back to the people doing it
Not to replace the clinician, the agent, or the attorney — to hand them a surface where the thinking and the shipping finally happen in the same place. The rest of this canvas is yours.
The people
A small team that has done this before.
OpenCharts is built by the same group behind TheoVex — people who have shipped in insurance and healthcare, where the rules are real and the tolerance for a wrong answer is zero.
Tony Feijoo
Co-Founder
Spent a decade building one of the country's largest insurance field organizations, which is where the team learned what real operators will and will not adopt.
Alexandr Vinocurov
Chief Operating Officer
Runs execution. Turns a research lab's output into products that ship on a schedule and hold up once people depend on them.
Daniel Diaz
Chief Legal Officer
Owns the guardrails. Every product decision that touches privileged or protected information goes through a legal review before it goes out the door.
The company behind it
OpenCharts is a TheoVex product.
TheoVex is an AI research lab for highly regulated industries — healthcare and insurtech first. The work is a customizable application layer over an inference layer, so a hospital or a carrier can build its own compliant tooling instead of renting someone else's. ARCA is the model family we develop in house.
Your work is yours. We do not train on customer data, and you keep ownership and control of what you put in.
- Theo
The agentic layer. The part that reads, decides, and does the work across every surface.
- Hitheo.ai
The orchestration API. How other products reach that agentic layer programmatically.
- OpenChartsYou are here
This product. The creation surface where a person and Theo build something together.
Why we built it
Three things we refuse to get wrong.
One surface, not eleven
The deck, the doc, the board, the sheet, the site, and the video were never separate problems. They were one problem split across a subscription stack. OpenCharts puts them on a single canvas so the thinking does not get lost between tools.
You own the output
Everything you make is exportable and yours. Nothing you build here is trapped behind a renewal, and nothing you write becomes training data for a model somebody else sells.
Built for the strictest room first
We started in healthcare and insurance, where a wrong answer has a consequence and a data policy is a contract. Building for that room first is what makes the product safe to use in every easier one.
Good to know
Frequently asked
Wait — this About page IS an OpenCharts canvas?
