Founded in 2019 by Zach Coelius, who serves as the sole general partner, Coelius Capital has evolved with a clear focus on early-stage investments in B2B software companies across the United States. Zach Coelius brings a unique perspective by investing in sectors where he has a strong Bayesian knowledge base, explicitly avoiding areas like crypto, web3, hard sciences, and bio. This focused approach has shaped the firm's investment philosophy and portfolio composition since its inception[1][3][4].
