Nyquis Raises $6.3M Seed Funding for Grid Monitoring

Nyquis, a San Francisco, CA-based provider of continuous monitoring systems for the electrical grid, has raised $6.3 million in a seed funding round.

The round was co-led by Gigascale Capital and South Park Commons with participation from Allison Pickens Ventures,Friale, Sovereign’s Capital, Pioneer Fund, Script Capital, and Lost Coast Ventures.

The company will use the funding to develop new sensor and capacity-planning products, expand its fault-training data and deploy its systems with more grid operators.

What is Nyquis?

Nyquis develops technology that helps electricity providers monitor power lines and identify potential problems before they cause outages or fires.

Its main product, the Nyquis Node, adds a digital monitoring layer to existing electrical substations. The device can be installed in about 15 minutes without shutting down power or rewiring equipment.

The system combines high-resolution sensors, precise time synchronization and edge computing to monitor electrical waveforms continuously. It analyses data locally rather than sending raw measurements to the cloud.

Nyquis uses machine learning models to analyse voltage and current measurements captured thousands of times per second. Trained on more than 200,000 simulated faults, the models can identify electrical problems that conventional protection equipment may miss, including faults drawing less than one amp.

How Much Funding Has Nyquis Raised?

Nyquis has raised $6.3 million in its seed funding round. The company has not disclosed details of any previous funding rounds or its total funding before this investment.

Who Invested in Nyquis’ Seed Round?

The $6.3 million seed round was co-led by Gigascale Capital and South Park Commons.

Other participating investors include:

• Allison Pickens Ventures
• Friale
• Sovereign’s Capital
• Pioneer Fund
• Script Capital
• Lost Coast Ventures

Why the Funding Matters

Nyquis plans to invest the funding in new sensors and capacity-planning products. It will also expand the data used to train its fault-detection models and install its monitoring systems with additional grid operators.

These developments will support the company's work to help electricity providers detect faults and make better use of existing grid infrastructure.

Who founded Nyquis?

Nyquis was founded in 2026 by Daniel J. Hunter and Steve A. Bukowski. The company is headquartered in San Francisco, California.

Bukowski serves as co-founder and CTO. He previously worked as a principal investigator at Idaho National Laboratory and developed the machine learning models used by Nyquis.

“The goal is to find the problem while the lights are still on,” said Daniel J. Hunter, Co-Founder and CEO of Nyquis. “When crews know where to look, they can address hazards sooner. We want to help utilities take that earlier action so fewer problems become emergencies and fewer communities face broad power shutoffs.”

Market and Business Growth

Nyquis has completed an initial deployment with Otero County Electric Cooperative in New Mexico.

During a windstorm, the system detected more than 50 high-impedance fault events caused by branches repeatedly contacting power lines. The cooperative's existing equipment had not detected these events.

Nyquis identified four locations where the problems were occurring. After crews addressed three of them, the warning signals at those locations stopped, while the fourth location continued to show activity. This also allowed the system to help operators check whether repairs had worked.

What Happens Next?

Nyquis plans to develop its sensor and capacity-planning products, improve its fault-training data and expand deployments with grid operators.

The company also aims to build on its fault-detection technology to give electricity providers better visibility into grid conditions and help them plan for additional power demand.
