New photo of the 99.998% pure gallium we’ve recovered from real U.S. industrial waste. More to come. @supra_elemental @CriticalJordan @Melt_Dem

first met @CriticalKatie on a retreat in 2022 where we nerded out on energy tech. we were both trying to figure out what we wanted to do next.

2 yrs later I joined @CrucibleCap (my dream role with my mentor @Melt_Dem) and @CriticalKatie pursued her dream of becoming a founder. she was kind enough to let us invest ;) you really can just do things!!🥰

excited to lead the first financing round for Supra

they use polymer chemistry to recover and monetize critical materials like gallium (and scandium) from mining streams at low cost, turning a liability into an asset

today, China dominates 99% of gallium production 👇

So excited to share what we’ve been working on at Supra. 🧪🧽 This ‘chemical sponge’ sucks up the valuable minerals in polluted water https://t.co/8wIEXHP4W4
