Steven Jepeal
Steven Jepeal is the co-founder and CEO of Allium Engineering, a Massachusetts deeptech startup making bridges last 100 years instead of 30. An MIT nuclear-engineering PhD who once worked on fusion reactor materials, Jepeal pivoted from the physics of plasma to the unglamorous economics of rebar, inventing a way to clad ordinary steel reinforcing bar in a thin layer of stainless so it stops rusting. The trick: the process slots into existing steel mills without changing how they operate. Allium's clad rebar is already in bridges in California and Florida, and Jepeal was named to the Forbes 30 Under 30 list for Manufacturing & Industry.
