The whole picture is drawn the way an old terminal would draw it.
Every surface is made of glowing text characters, mostly cold cyan on
black. It is the top floor of a corporate headquarters at night, and
the headquarters has a staff of one.
Floor-to-ceiling windows look out over a city of dense towers with
lit windows and rooftop beacons. An elevated highway carries streams
of amber traffic toward the horizon, a tram crosses on a viaduct, and
flying cars drift between the buildings.
On the left, a projector on a pedestal casts a hologram of the
Earth: a globe of light points with the continents picked out
densely, turning slowly inside a wireframe of latitude and longitude
lines. The words CALVO CONGLOMERATE and a copyright sign orbit it.
Three cables with glowing rings snake across the floor from the
projector to the desk.
On the right, at a curved desk under a row of floating screens, sits
the staff: a faceless, low-poly figure in solid red, the one solid
red thing in the room. The screens show a stock chart for the ticker
CCG, a scrolling system log that ends in ALL NOMINAL, and banks of bar
graphs. The figure types at a floating, lit keyboard. Every so often
a screen flashes NEW VISITOR! in red. The figure flinches, swivels to
read it, and taps it away. Then it picks up a remote, rolls the chair
back, swings its boots up onto the desk one after the other, crosses
its ankles, and reclines, pointing the remote out at the visitor,
before sitting back up and returning to work.
Above the city hang three glowing plates, like a building directory:
About, Services, and Work. They are the site's menu. The three
links after this description are those plates.
From prototype to production: through the security
review, the compliance audit, and onto your own hardware.
Calvo Conglomerate is a diversified holding company. It has one
employee.
Its subsidiaries operate across applied
AI, software engineering, security, infrastructure, and additive
manufacturing.
Meet the Board
-
David Calvo
Chairman of the Board
Mr. Calvo has chaired the board since the Conglomerate's formation and sets its agenda.
- CISO and Lead Engineer, Pneuma Solutions. Built its on-premises document accessibility engine (custom Rust PDF parser and layout ML) running inside the world's largest legal research platform, alongside its SOC 2 Type II program.
- Creator of Mia, the multi-agent AI hologram at Lifetown Columbus.
- Previously at Proton.ai, scaling the data pipelines behind its recommendation models from gigabytes an hour to terabytes.
- B.S. and M.S.E. in Computer Science, Johns Hopkins University (A. James Clark Scholar).
-
David Calvo
Chief Executive Officer
As Chief Executive, Mr. Calvo is responsible for the Conglomerate's commercial operations and strategy. He negotiated Pneuma's flagship six-figure enterprise licensing agreement directly with the customer's procurement and security teams, and reported it to the board the same day.
-
David Calvo
Lead Independent Director
Designated Lead Independent Director by his fellow directors, Mr. Calvo speaks for the board outside it. In 2021, NATO invited him to speak on AI-assisted medical decision-making; the Digital Triage Assistant that came of it was later covered by CNN.
-
David Calvo
Chair, Audit Committee
The board has determined that Mr. Calvo qualifies as an audit committee specialist. He designed and runs a live SOC 2 Type II compliance program and an EU/US data-residency architecture from the ground up, auditors and all.
-
David Calvo
Chair, Compensation Committee
The Compensation Committee sets executive pay. Its chair is Mr. Calvo, whose own compensation it also sets, and who previously won the Johns Hopkins Business Plan Competition for A Set of Eyes, the computer-vision screen reader he founded.
-
David Calvo
Chair, Nominating and Governance Committee
Mr. Calvo has recommended every director currently serving. He learned governance at the Department of Homeland Security's Office of the CIO, where as a Secretary's Honors Program intern he led a team that reworked the tracking of more than 600 security controls and cut the time to an Authority to Operate (ATO) by up to 40%.
-
David Calvo
Shareholder Representative
Holding a standing proxy from the Conglomerate's sole shareholder, Mr. Calvo guards its capital as he would a client's. The on-premises GPU training cluster he built—eight V100s and 300 TB of storage—runs for about $1,000 a month against $22,000 for the equivalent on AWS.
The Conglomerate has five subsidiaries at present and
remains acquisitive. Work is scoped either as a fixed-term sprint to
clear a specific blocker or as an ongoing leadership role on your
team.
How engagements start
- Production & Security Readiness Sprint. Two to four weeks, fixed
scope. For an AI product that works in the demo and is stalled
at a security review, a procurement questionnaire, or a
customer's own hardware. We find what will fail there, build the
fix, and sit on the call when their CISO asks how it works.
- Fractional Principal / vCISO Retainer. A
standing role on your team: senior engineering and security
leadership, part time, for as long as it is useful. It usually
follows the sprint.

The Subsidiaries
- Applied AI. Machine learning for the problems your
business has: language models, models trained on your own data,
or both. We take an idea from feasibility to production, and stay
on so it keeps working once it is there.
- Software Engineering. Software you can rely on. From
greenfield builds to rescuing a stalled project, we bring senior
engineering to every stage: architecture, implementation, code
review, and the decisions that are expensive to get wrong.
- Security. Security leadership for companies that need it
without a full-time hire. We build the program, handle the
auditors and the security questionnaires, and make sure your team
knows what to do before it has to.
- Infrastructure. Systems that stay up. We design, build, and
operate the environments your software runs in, whether that is
the cloud, your own hardware, or both.
- Additive Manufacturing. One printer. Output is
predominantly 28 millimeters tall and armed.
The engagements the Conglomerate is permitted to
discuss.
Pneuma Solutions
Pneuma Solutions makes assistive technology. The Conglomerate
designed its SOC 2 Type II program and EU/US data residency, and
runs both. It also built the company's on-premises document
accessibility engine, which enterprise customers run inside their
own infrastructure.
It is what makes the world's largest legal research platform
readable to blind and visually impaired users. Every PDF and every
page of HTML the platform serves them passes through the engine
first, and the same is true of its sister platforms for tax and
accounting professionals. It cleared the owner's security review,
runs on its hardware, and has served at that scale since.
Underneath, the stack was built from scratch. Its PDF processing
is written in Rust, on the open-source
hayro and
krilla libraries,
to which the Conglomerate has had eleven pull requests merged. The
research behind it includes a document layout model, trained in
house on a corpus curated toward 300 million pages, that reads
each page as a tree rather than as a scatter of boxes.
Lifetown Columbus
Mia, a “Super Buddy.” A life-size AI hologram that
helps children with special needs practice life skills by teaching
them to her. The Conglomerate designed and built the system end to
end: multi-agent orchestration, deterministic conversation state,
low-latency voice, and hardware integration. The town she lives in was already there.
Unveiled September 2026 with Ohio's governor in attendance. In a
study run by researchers from Miami University in Ohio, two groups
of students were asked whether they wanted to continue: about 70% of
those talking with Mia did, against 30% of those working a
worksheet.
