Pulmatrix is a small biotechnology company that develops inhaled medicines to treat lung diseases and infections. Its main focus is on a drug delivery technology called iSPERSE, which turns medicines into dry powder that patients breathe directly into their lungs. The company has worked on treatments for fungal lung infections, including a drug called PUR1900 targeting a condition called allergic bronchopulmonary aspergillosis, primarily for patients with asthma or cystic fibrosis.

Pulmatrix does not yet sell any approved products, so it earns no product revenue and relies on partnership deals, licensing agreements, and grants to fund its research. It is a very small company based in Lexington, Massachusetts, with a market cap near zero, meaning investors currently place little value on its pipeline. The biggest risk the company faces is running out of cash before it can get a drug approved, which is a common challenge for early-stage biotechs with no commercial products on the market.

Cash watch
