How we move from SST prototype to scaled deployment.
Finalize converter, transformer, protection, and controls architecture for the first integrated SST prototype.
Validate high-frequency magnetics, switching nodes, and control loops under representative stress conditions.
Run hardware-in-the-loop and fault-injection scenarios to de-risk full-system behavior before pilot deployment.
Complete design and test gate review with pilot success metrics, instrumentation plan, and deployment requirements.
Select pilot sites with strong technical and operational fit, including utility, data-center, and industrial candidates.
Define integration interfaces, protection boundaries, controls handoff, and commissioning sequence with host teams.
Launch pilot units with telemetry, diagnostics, and continuous performance tracking against agreed KPIs.
Use pilot data to refine hardware and software, then scope expansion with strategic partners.
Map target standards, interconnection constraints, and safety requirements for priority application segments.
Execute structured EMC, thermal, protection, and reliability campaigns early to shorten formal certification cycles.
Build traceable evidence bundles covering design intent, test results, and safety cases for certifying bodies.
Submit and support review cycles, then fold outcomes back into release-ready product baselines.
Harden bill of materials, sourcing strategy, and component risk controls for repeatable build quality.
Convert prototype knowledge into controlled production work instructions, fixtures, and verification plans.
Establish manufacturing feedback loops to improve yield, detect drift, and maintain field reliability targets.
Prepare phased volume ramps with quality gates, burn-in plans, and serviceability checkpoints.
This capability is in development. Reach out to join early access for telemetry and controls software pilots.
We are building a software layer for real-time monitoring, adaptive control tuning, fault analytics, and fleet-level optimization across deployed SST assets.
The goal is a programmable power platform where hardware and controls continuously improve from field data.

Founder / CEO
Marc Ordoñez has been building things for as long as he can remember. As a kid, that instinct showed up as taking apart electronics to understand how they worked. As an engineer, it evolved into designing the systems that move energy itself.
Marc founded Polyax with a clear objective: build power electronics platforms that enable the next generation of energy infrastructure. At the company, he leads the development of modular high-voltage conversion systems designed to bridge grid, storage, generation, and high-power loads.
Before Polyax, Marc led a power electronics team at TWMC, helping scale the business from $3M to $60M in annual revenue while securing multiple multimillion-dollar grants and projects. Outside of engineering, Marc channels that same drive for precision and challenge into aerial arts, skiing, scuba diving, and building experimental software projects.
Co-Founder / Chief Strategy Officer
Evie Loper has a system for everything. Whether it is a company operating model, a training program, a knowledge management architecture, or a Formula 1 sleep schedule, she approaches complex problems the same way: break them down, build the right structure, and let the system do the work.
At Polyax, Evie designs the company's operating architecture, partnership strategy, and commercialization pathways for next-generation power electronics platforms.
Before co-founding Polyax, she led strategic partner initiatives inside a Fortune 50 environment, managing Comcast's largest national distributor partnership and directing more than $14M in performance and incentive programs. With a background in Computer Software Engineering with an emphasis in AI, Evie is most comfortable where complexity lives.
Lead Embedded Software Engineer
Steven Haertling has engineered the perfect cup of coffee. His espresso setup is a custom-modified machine connected to a smart home system he built himself, allowing him to control temperature, timing, and extraction with the same precision he brings to embedded systems.
At Polyax, Steven leads embedded software development for the control systems that operate the company's high-frequency power electronics platforms. He previously served as a Lead Software Engineer in the power electronics group at TWMC, where he specialized in high-frequency embedded technology and advanced control architectures.
Whether it is a converter control loop or a morning espresso shot, Steven approaches engineering the same way: understand the system, instrument it properly, and optimize until it performs exactly the way it should.
Lead Systems Engineer
David Miller's path into power electronics started with a different kind of problem: why data centers lose power. Early in his career, David worked at a reliability engineering company diagnosing and solving power issues in Dell data centers in the Austin area.
That experience gave him a front-row seat to the realities of large-scale electrical infrastructure and the consequences when it fails. He later moved into designing the systems themselves, serving as Lead Electrical Engineer at TWMC before joining Polyax.
Today he leads system architecture and electrical design for Polyax's modular high-voltage power platforms. Outside of engineering, David collects classic video games and physical media, tends to an ever-growing collection of plants, and grows dragon fruit.
