Different sectors.
Real results.

I

Energy

Innovating on-site generation and microgrid systems to deliver reliable, affordable, uninterrupted power.

Power built around your operations

We bring together the people and capabilities to develop on-site generation and microgrid solutions for organizations that depend on reliable, affordable power.

From concept to ongoing operation

Our approach connects project assessment, design, permitting, utility interconnection, installation, commissioning, and long-term operations and maintenance. Generation, battery storage, solar, and controls are selected around the facility’s loads, operating priorities, and budget.

Supporting critical infrastructure

Planning power and critical loads together helps support continuity for healthcare, industrial operations, and private AI infrastructure when utility service is disrupted.

II

Private AI

Delivering private AI integrated into your organization’s knowledge and workflows, supported by resilient infrastructure and ongoing management.

AI that works within your organization

We design and integrate private AI around your proprietary documents, systems, and workflows, on-site or in a customer-approved private environment. Applications include internal knowledge search, employee assistants, and workflow automation.

The right technology for the mission

Our approach is technology-agnostic. We evaluate hardware, models, and software against your workloads, security requirements, existing systems, budget, and growth plans—including ecosystems such as NVIDIA, Dell, Lenovo, and HPE.

Ownership and ongoing support

Choose customer-owned infrastructure or a Stellen-managed service, with ownership and service levels defined by agreement. We bring together design, procurement, installation, integration, commissioning, and ongoing maintenance and management.

Private intelligence. Resilient power.

We draw on our experience with on-site generation and microgrids to support private AI designed for uninterrupted operation. Planning power resilience alongside compute helps build an internal capability that stays close to your data and becomes part of everyday operations.

III

Neurotreatment

Employing cutting-edge technology to treat mental health conditions and support people with disabilities.

Technology with a human purpose

Our focus is on bringing people, technology, and healthcare expertise together to expand opportunities in mental health and support for people with disabilities.

Building the right partnerships

We seek relationships with qualified clinical providers, technology developers, and delivery partners to identify practical needs, evaluate potential solutions, and support responsible implementation.

From need to execution

We apply the same approach across our work: understand the problem, assemble the right team, and build a practical path toward better access and meaningful impact.

IV

Government contracting

Leveraging networks and partnerships to pursue competitive contract opportunities.

Mission-focused partnerships

Stellen Defense is a service-disabled veteran-owned small business that brings relationships and practical delivery experience to government contracting opportunities.

The right team for the requirement

We connect technical specialists and delivery partners around defined requirements, combining complementary capabilities to pursue competitive bids and develop a clear approach to execution.

Relationships through delivery

Our focus is on understanding the mission, defining responsibilities, and aligning the team around scope, schedule, and results across energy, private AI, and healthcare-related opportunities.
