We’re Signing The Mensarius and the Ærarius Oaths

Why Airvolt Anchors Its Growth in Stewardship, Not Extraction


At moments of institutional change, organizations either reach for shortcuts or they formalize their values in ways that endure scrutiny, time, and scale. Airvolt has chosen the latter.

As Airvolt evolves from its modest beginnings into what is increasingly an infrastructure and long-term investment platform, we have adopted two complementary ethical oaths. Each speaks to a different but inseparable responsibility. One governs how capital, influence, and experience are deployed in entrepreneurial ecosystems. The other governs how technology, data, and infrastructure are built and stewarded in the public interest.

These are the Mensarius Oath and the Ærarius Oath.

Together, they form the moral architecture of Airvolt.


I. The Mensarius Oath

Origins, History, and Modern Relevance

The word mensarius comes from ancient Rome. Mensarii were public bankers appointed during times of financial stress. Their role was not to extract profit, but to stabilize systems, protect citizens, restructure obligations, and restore trust when markets failed.

In the modern era, the concept was revived and formalized by Adeo Ressi, who observed a structural problem in contemporary entrepreneurship. Capital, mentorship, and influence were increasingly concentrated, while ethical responsibility remained diffuse.

The result was a gap. Founders were celebrated for speed and scale, but not for restraint, care, or ecosystem health.

The Mensarius Oath was devised to close that gap.

It is an oath for those who hold leverage. Investors, advisors, board members, repeat founders, and institutional actors whose decisions shape outcomes far beyond their own balance sheets.

At Airvolt, we adopted the Mensarius Oath because we recognized a simple truth. If we benefit from entrepreneurial ecosystems, we are obligated to leave them stronger than we found them.

Why the Mensarius Oath Matters at Airvolt

While Airvolt began as a focused technology company, its trajectory increasingly places it at the intersection of infrastructure, capital, policy, and long-duration systems.

Infrastructure companies do not merely sell products. They shape cities, data flows, energy decisions, health outcomes, and institutional trust.

The Mensarius Oath reminds every cap table member, advisor, and leader at Airvolt that influence is not neutral. Capital is not passive. Silence is not harmless.

As Airvolt grows, the responsibility encoded in the Mensarius Oath becomes more, not less, important.


II. From Mensarius to Ærarius

Why Airvolt Needed a Second Oath

The Mensarius Oath governs how we behave toward founders, partners, and ecosystems.

But Airvolt builds infrastructure.

We deploy sensors, platforms, data pipelines, and operational intelligence that increasingly intersect with public health, environmental outcomes, and municipal decision-making.

This required a second oath.

In ancient Rome, the aerarium was the public treasury. It was not private capital. It was sovereign responsibility. Those entrusted with it were accountable not only for accuracy and efficiency, but for continuity, legitimacy, and restraint.

Inspired by Adeo Ressi’s Mensarius Oath, Anton Radulea, Airvolt’s Founder and present-day CEO, developed the Ærarius Oath to reflect the ethical responsibilities of building and operating infrastructure in the modern world.

This oath is signed by those involved in technology, data, deployment, and operational leadership.


III. The Ærarius Oath

Stewardship of Technology as Public Trust

The Ærarius Oath recognizes that certain systems, once deployed, cannot be undone without consequence. Air quality data. Environmental analytics. Urban infrastructure. These are not mere features. They are inputs into real decisions affecting real people.

The oath formalizes how Airvolt approaches this responsibility.

The Ærarius Oath

Inspired by the Adeo Ressi’s Mensarius Oath, co-authored by Anton V. N. Radulea

I, the undersigned, ________________________________________________,
affirm this oath and accept the responsibilities it establishes.

I pledge to build and deploy technology in a way that contributes to human well-being, public health, and societal progress.

I commit to acting with integrity, honesty, and accountability, especially when decisions are difficult or when no one is watching.

I will not pursue value through deception, information asymmetry, or the exploitation of partners, investors, or customers.

I will treat data, air quality, environmental impact, operational analytics, as a public trust, ensuring transparency, accuracy, and responsibility in how it is collected, stored, and shared.

I will contribute to the ecosystems I operate in, not extract from them. In every city, every building, every deployment, I will seek to leave the air cleaner, the infrastructure smarter, and the relationships stronger.

I will support founders, teammates, and partners with empathy, clarity, and generosity, understanding that durable innovation emerges from aligned effort and shared purpose.

If I lead, I will lead with humility. If I follow, I will do so with diligence. If I advise, I will do so with care.

I will take responsibility for my decisions, my impact, and my exchanges, understanding that the quality of my work reflects the quality of my character.

In everything I build with Airvolt, I will honor the principle that progress must never come at the cost of people, trust, or integrity.

IV. Two Oaths. One Standard.

The Mensarius Oath and the Ærarius Oath are not symbolic artifacts. They are operational commitments.

Every Airvolt cap table member will eventually have both oaths signed and attached to their individual bio pages on Airvolt’s Team Pages, accessible via the Who We Are section of the website. This is intentional.

Why did the Founder consider that Cap Table Members should sign both?

Because capital without stewardship becomes extraction.
Because technology without ethics becomes externalized harm.
Because infrastructure without accountability eventually loses legitimacy.

The Mensarius Oath governs how we use influence.
The Ærarius Oath governs how we build systems.

Together, they define what kind of company Airvolt is becoming.


V. Why This Matters Now

We live in an era where trust in institutions is fragile, where infrastructure decisions are increasingly opaque, and where technological power often outpaces ethical reflection.

Airvolt believes that values should not be implied. They should be written, signed, and revisited.

These oaths are not constraints. They are compasses.

They exist to remind us that scale amplifies character, that progress is only meaningful if it endures, and that the true measure of success is not what is extracted, but what remains stronger after we are done.
