Company profile

researched Aug 2026

Gentle Energy Corp. (์  ํ‹€์—๋„ˆ์ง€ ์ฃผ์‹ํšŒ์‚ฌ) is a Seoul-based company that develops sensing hardware and AI software for monitoring and reducing energy consumption in buildings and industrial facilities. Its stated vision is to protect the environment through more efficient energy use, and its mission emphasizes providing knowledge and automated tools that lower the barrier to adopting energy-efficiency solutions so they can be operated with minimal resources.

The company's principal offering is Etamateยฎ, a solution for data collection, analysis and equipment control aimed at improving the energy efficiency of buildings and equipment. Etamate collects real-time data via the company's self-powered Fluxuiยฎ sensors and applies the Etamate AI engine together with nTorque inverter control technology to optimize energy efficiency. In the English-language description, Etamate is positioned as an automatic data-collection solution for factory management, delivering the data needed for energy and productivity optimization through AI analysis. Earlier product history includes the Factoroid trademark registration (2020) and the Factoroid 1.0 release (2021), plus a smart farm air-quality monitoring service launched in 2022.

Founding story

The company grew out of research on friction (triboelectric) power generation elements; in 2019 it developed technology to harvest electrical energy from the vibration of objects, and the corporation was established in September 2019.

Business model

Gentle Energy sells an energy-efficiency solution (Etamate) combining self-powered sensors, an AI analytics engine and inverter-based equipment control to customer sites, positioned as a low-barrier service that can be operated with minimal resources.

Traction

The company reports 78 patents and certifications, more than 250 (clients per the Korean site; the English site labels the same figure as increase in sales), and more than 1,000 analyzed panels, plus partners. It recorded 30 solution deployments by December 2022.

Latest developments

In June 2023 Gentle Energy signed an MOU with Korea East-West Power Co., Ltd. for energy-efficiency commercialization and attracted bridge investment. Its website, updated with a 2025 copyright notice, presents the Etamate solution with Fluxui self-powered sensors and nTorque inverter control.

โ–ธFull profile โ€” market position, technology, go-to-market, geography, history

Market position

Positions itself as a provider of practical, economically efficient sensing and AI technology for energy efficiency, working with Korean utilities and telecom partners.

Combines self-powered (energy-harvesting) sensors that draw power from vibration, current, magnetic fields and light with a self-updating, general-purpose AI analytics model and inverter control, allowing deployment with minimal additional resources and low adoption barriers.

Technology

Two technology pillars are described. The first is a continuous-learning AI that converts time-series data collected from sensors into information such as equipment operating status, product output and power usage, delivered to customers in real time; the model is described as universal and self-updating. The second is energy harvesting: the company began with friction (triboelectric) power generation research and in 2019 developed technology to harvest electrical energy from the vibration of objects, later extending harvesting to sources including current, magnetic fields and light. Related technology assets include a patent registration for a method of analyzing electrical signals of frictional electricity generation components (2021), a sensor device design registration for packaging (2022), and KC and CE certification of its smart sensor (2021). The company reports 78 patents and certifications.

Go-to-market

Direct sales through a company sales contact, supported by partnerships and memoranda of understanding with larger Korean corporates, including LG U+ (September 2022) and Korea East-West Power Co., Ltd. for energy-efficiency commercialization (June 2023).

Operators of buildings and industrial facilities, including factory management, as well as smart farm operators served by its air-quality monitoring service.

Geography

Headquartered in Seoul, South Korea; the Korean site lists an address in Mapo-gu (Saechang-ro 11, Suite 1208, Dohwa-dong, Gongdeok Building) and the English site lists 2nd floor, 27 Seongji-gil, Mapo-gu, Seoul.

History

The corporation was established in September 2019, following friction power generation research and the 2019 development of vibration energy harvesting. It attracted Pre-A investment in December 2019, obtained venture company certification in February 2020, and occupied the Seoul Global Startup Center (May 2020) and Seoul Startup Hub (October 2020). In 2021 it established a corporate-affiliated research institute, released Factoroid 1.0, was selected as a military service exemption company, and won the Try Everything 2021 Korea Challenge Grand Prize and the 10th Youth Entrepreneurship Competition. In 2022 it relocated and integrated its Hapjeong office, raised a Series A round in March, won an Edison Award (Silver) in May, signed an MOU with LG U+, launched a smart farm air-quality monitoring service and reached 30 solution deployments. In June 2023 it signed an MOU with Korea East-West Power for energy-efficiency commercialization and attracted bridge investment.
