Helisep
Helisep is developing a quantum sieve that recovers helium-3 from helium already moving through the world’s pipelines. Before its first bench result, we gave it a brand, a website, investor materials and an atlas of exactly where the opportunity sits.
Evidence an investor can explore for themselves
A company without hardware yet still has to show investors where the opportunity is. The Global Helium-3 Atlas does that in the open.
The atlas combines four public datasets into one interactive map with three views, covering opportunities, science and infrastructure. Filters and layers bring in curated projects, isotope observations, ranked U.S. fields and well samples, and the map pulls live official data on wells, licenses and pipelines. Anyone can see where helium-3 already flows and the evidence behind each point.
Atlas sources include the USGS helium-in-wells dataset (Brennan et al., 2021) and a helium isotope dataset published on Zenodo (Gherardi et al., 2025). Counts reflect the atlas data build of September 27, 2026.
Engineered, precise and a little bit warm
The mark is a molecule of three outlined atoms joined by orange bonds, with one solid atom standing apart. Deep navy and platinum carry the science, orange is kept for the opportunity, and a technical display face pairs with IBM Plex for text and data.
The same story, behind a sign-in
Behind a sign-in, an investor portal handles reviewed access requests, a data room and activity tracking. The pitch deck tells the same story in the same visual language, so the public site, the atlas and the deck reinforce one another.
