Spero's mission is to make biological alchemy a reality. 

We’ve solved the key roadblocks to the industrial use of cell-free metabolic engineering. We're hitting the ground running with a reaction comprising nearly 70 enzymes. 

Why cell-free? Basically because we don't want to waste carbon flux. We direct the power of enzymes toward a single, well-specified goal instead of taking a detour into growing an entire organism first. 

Spero is a two-person team based in Austin, TX. We're always looking for outstanding microbiologists and engineers to join us. If this describes you, please reach out at mm[at]spero.bio, and tell us about the most impressive thing you've built. We're at an early stage, so significant equity stakes are still on the table.
