# Meet Allium Engineering

![Allium_logo_2color_RBG_dark](https://propellervc.com/hs-fs/hubfs/Allium_logo_2color_RBG_dark.png?width=456&height=119&name=Allium_logo_2color_RBG_dark.png)

Allium addresses one of the hardest problems in the ocean-building things that last. Their stainless clad rebar will change how we scope ocean and coastal builds.

**Location:** Boston, MA, USA

**How we met:** Jake Russell found 'em!

**Propeller theme:** Ocean Industrials

**Propeller investment stage:** Seed  

Allium creates stainless-cladded rebar. This is a core building block for ocean infrastructure; both in its ability to withstand corrosion, and last for financeable timelines at competitive pricing.

- Why we love the founders – Steve Jepeal and Sam McAlpine met at MIT. They are excellent complements to each other, and deep subject matter experts. 
- What’s novel about Allium’s tech – Allium is focused on longevity to avoid emissions-they’ve focused on a low-cost product that is tailor made for coastal infrastructure. 
- Why we’re excited about this market – a green transition is predicated on a LOT of infrastructure being built or retrofitted. Rebar is everywhere and crucial to a majority of that infrastructure. 
- How impactful Allium could be – steel is one of the largest emitting sectors of carbon in the world. By extending longevity, Allium could avoid gigatons of expected emissions in the coming decades of replacement steel.
