Atommer Raises Seed Funding from LG Electronics and Bluepoint Partners to Scale Asset-Light Materials Platform

Atommer, a South Korean startup developing functional materials through a fabless business model, has raised a seed round from LG Electronics and Bluepoint Partners, the company announced on August 24.

The investment was made through STUDIO341, a corporate venturing program jointly operated by LG Electronics and Bluepoint Partners, following Atommer’s spin-off as an independent legal entity. The size of the round and post-money valuation were not disclosed.

Materials startups have traditionally faced significant barriers to commercialization: even with proprietary technology, they have required massive upfront capital expenditure (CAPEX) to build production facilities and years to establish mass-production systems, delaying market entry and revenue generation.

Atommer addresses this bottleneck by applying the semiconductor industry’s fabless model to the materials sector. The company retains core materials design in-house while partnering with specialized third parties for technology validation and commercialization at each stage. This “asset-light” strategy reduces initial capital requirements and shortens time to market.

Atommer’s first product is an ultra-thin thermal barrier coating designed to control battery fire risk. The coating can effectively block high-temperature flames at thicknesses below 100 micrometers. Unlike conventional intumescent coatings that expand significantly under heat exposure, Atommer’s non-expansion formulation preserves internal space efficiency in battery systems.

The company plans to complete proof-of-concept trials in the second half of 2026 and expand into IT and consumer electronics applications, including passive cooling tapes to address rising thermal management challenges in high-power-density devices.

“The biggest hurdle facing traditional materials startups is the enormous cost of building production infrastructure and the long lead time to mass production,” said Byeong-seong Kim, CEO of Atommer. “Through a rigorous division-of-labor ecosystem with specialized partners at each stage, Atommer will grow into an innovative materials fabless company that delivers a diverse range of functional materials to market more easily and quickly.”

“Atommer’s fabless model, built on exceptional materials expertise, overcomes the burden of facility investment and maximizes market entry speed,” said In-seong Lee, head of the Venture Studio Group at Bluepoint Partners. “We expect the company to drive meaningful change in the materials market.”

STUDIO341 was launched in 2023 to carry forward the founding spirit of Goldstar—LG Electronics’ predecessor—by incubating internal ventures. Bluepoint Partners manages the full lifecycle from selection through nurturing to spin-off in collaboration with LG Electronics.

South Korean deep-tech startups are raising capital to overcome traditional infrastructure costs and shorten commercialization timelines. Point2 Technology raised an $80 million Series B extension in August 2026, bringing cumulative funding to $140 million for AI interconnect solutions, and JLABS landed an $8.1 million pre-IPO round in July to fund missile-defense localization and its IPO push.
