Private Holding Company

Evidence-based predictive decisions.Scalable AI with guided autonomy.Brands that strengthen the ecosystem.

Tenacera is a private holding company and venture studio. We build health, intelligence and software companies, and consumer brands that last. Many of our capabilities are designed to serve outside businesses and founders as well as our own portfolio.

The Tenacera ecosystem is scalable, AI-driven and clinically evidence-based. Each company is its own business serving outside clients, and they work with one another through licensing and similar arrangements. Shared services spare each company its own back office, so costs stay lower and the whole grows faster.

The Peregrine

Pure tenacity, at speed.

The peregrine falcon is the fastest animal on earth. It fixes on its quarry from a great height, long before anything else has seen it, then folds its wings back and drops into a stoop that passes 200 miles an hour.

Almost nothing else could survive that dive, let alone steer through it. The peregrine does both. It stays in complete control from the first second to the last, because it chose its target before it ever left the sky. That is how we want to work: patient sight, a clear objective, total commitment. It is also where our name comes from. Tenacera is tenacity, built into a company.

Clinical responsibility is the first constraint. Every venture in the portfolio is built from that chair outward — formulation, diagnostic, and software treated as the same object.

Where Clinical Evidence Meets Scalable Technology

Most health and wellness ventures are built by marketers who license science they do not understand. Most enterprise AI is built by engineers who have never carried responsibility for a decision with a patient, a regulator, or a balance sheet on the other side of it. Both categories optimize for the story before the substance.

Tenacera is built from the other direction — clinical practice first, then the technology to scale it. The operating principle is simple: a formulation, a diagnostic, and a software system are all the same object. Each is a decision architecture, and each must survive contact with real-world evidence.

Evidence has layers. Claims have to survive all of them.

Most health ventures license science they do not understand. Most enterprise AI is built by people who have never carried a decision with a patient on the other side of it. A formulation, a diagnostic, and a software system are all decision architectures. Each has to survive contact with real-world evidence.

01

Formulate on Evidence

Every product begins in clinical practice, not in a marketing brief. Claims are constrained by what the underlying science can actually support.

02

Build for Institutional Scale

Systems are designed for regulated, high-consequence environments from day one. Compliance, auditability, and reliability are architecture, not afterthoughts.

03

Own the Full Stack

Formulation, manufacturing relationships, software, and distribution are developed within the holding company. The same software and delivery capabilities are designed to serve outside clients. Owning the stack is what protects margin and standards.

The software layer is not a wrapper. It is part of the stack.

Formulation, manufacturing relationships, software, and distribution are developed within the holding company. The same software and delivery capabilities are designed to serve outside clients. Verification, auditability, and gated oversight are architecture — not a model output taken on faith.

Portfolio

Fourteen Companies and Platforms. Three Pillars. One Operating Thesis.

Our portfolio is a worked example, not the limit. The Leopard companies, MaxxForge and LUXXMARK are designed to serve outside customers with the same capabilities used here, for their own businesses and portfolios.

Dr. David Steuer

Founder & Managing Director

Serial venture creator and founder of a private holding company and venture studio. He builds where clinical formulation science meets applied artificial intelligence, and his doctorate-level training spans biochemistry, natural medicine, and sports nutrition alongside years of study in mathematics and systems architecture applied to complex human and machine reasoning.

That work stands on clinical ground. A Harvard-trained endodontist and microsurgeon, he has overseen more than 40,000 procedures — the operating experience that informs every formulation and software system in the portfolio. It is also why the ventures here are built around explicit reasoning architecture and gated oversight rather than model output taken on faith: in clinical work, a decision that cannot be audited is not a decision worth making.

Years of study, applied to systems that have to be audited.

Decades of clinical microsurgery, doctoral research encompassing biochemistry and natural medicine, and years of study in systems architecture have been directly applied to auditable decision engines and machine-based learning and architecture.
