A Natural Choice.

TerraNexum means "earth network."

Our company applies complex systems design principles to sustainability challenges involving energy and carbon resource flows.

QGO is our flagship product, scheduled for release at the end of this quarter. It uses AI and optimization to grow geothermal energy and carbon sequestration by providing a birds' eye view of market opportunities to meet community needs.

Our vision:  to provide the go-to platform for corporate and government stakeholders to derisk their projects, enabling the renewable energy with the least land and water footprint to achieve speed and scale.

Our work provides
not one, but three
sources of value.

We need energy.
And nature. And a
healthy economy
that provides for
both people
and nature.

All three: equally
important. Our
work: to advance
all three in balance.


QGO stands for Quantum Geospatial Optimizer.

Quantum so we can scale to larger problems and solve smaller ones more efficiently. Like where the components of the most cost-effective, efficient, community-supported geothermal assembly line might go.

Energy matters. When the lights are on, work gets done. Water is pumped. Food is grown. People thrive. But when nature declines and emissions rise, we pay a price.

A world of abundant renewable energy can exist in our near future. Only if we can marshal the resources to build the supply networks of both materials and people to achieve the achievable.

QGO was designed to visualize where those resources should go. On what supply networks. Ensuring that benefits to all stakeholders exceed costs.

Our fourth Industrial Revolution must include an assembly line. For the mass production of clean energy. To power a regenerative economy that rebuilds nature and empowers humanity.

A view from the new QGO. It's come far, and so has the world in understanding the importance of complex networks and flows. It's time for a tool to enable decision-making in a true systems context.

The Challenge We Face

Rolling out clean energy. Like cars.1

Using an assembly line, the Model T became the world's first mass-produced car. Its time to assembly: 93 minutes. Its cost: $26,000 in today's dollars.2

Today, a well up to 9,000 ft deep can be drilled in 21 days. Cost: $4.8 million.3

On one site to generate 400 MW of clean, renewable geothermal power, it may require up to 29 wells.Producing 3.5 GWh in a year if always on, which can be the case. The heat beneath our feet is always there.

In the US, we still use too much coal. In one year, burning coal generates 690 TWh of electricity, and also 0.774 gigatons of CO2 emissions.5 

Replacing these emissions with geothermal energy, clean renewable energy with the least land footprint, water consumption, and environmental damage from mining of all renewable technologies, will not be without great effort.

It will require 197,000 of the sites above. At a target cost of $100 per kWh,3 the total: $69 billion.6

QGO is designed to maximize energy and resource flows over networks that can become large. We've iterated on the best ways this can advance sustainability.

Any roadmap should include a map.

QGO - connecting funding sources to clean energy project developers to project sites

OpenQGO - our community version, demonstrating the concept.

Mission possible.

Through our work, we redefine what is possible.

If it is within the laws of physics and human capability, if knowledge, technology, and funding exists somewhere in the world, then "impossible" becomes a logistics problem.

A solvable problem. On its way to being solved.

These are the people at TerraNexum, committed to solving sustainable and inclusive growth. A significant challenge for this decade, according to McKinsey.

Leading by example.

Extended Team

Our pre-market team is lean for operational efficiencies given the current investor climate. As we achieve revenue and conditions improve, we will grow our team accordingly.

We plan to invite a total of 8 members to our Advisory Board in 2024.

Investors seeking an active role on our Board of Directors, please inquire.

We are grateful to our former TerraNexum interns:
Alyson (Allie) Westfall - Environmental Science
Shrila Esturi - Carbon Mineralization, CCS - OpenCarbon
Anish Jahagirdar - Quantum Optimization - OpenQGO

Investors and Programs


Our Delaware C Corporation has received committed funds from AngelList, available when our open funding round closes.

Cloud and Industry Programs

We are grateful to these programs for allocating enough in-kind support to offset approximately $400,000 of cloud expenses:

Google for Startups - Cloud AI
Microsoft for Startups
AWS Activate
NVIDIA Inception

And for providing additional value through software discounts, training, and events. Our product will provide value to these providers in turn. Through both our use of cloud resources and by onboarding new users.

TerraNexum has also been a registered contractor with C-PACE since 2022, in the area of renewable energy.
