Joshua Mandel-Brehm, CEO of CAMP4 Therapeutics, discussed the company’s approach to RNA therapeutics in a June 2025 interview at BIO Boston. He described CAMP4 as using antisense oligonucleotides to increase gene expression, positioning it as the inverse of companies like Ionis and Alnylam, and noted that hundreds of diseases involve missing healthy protein. He also commented on the transition from private to public company, stating that being public offers access to a broader set of shareholders and requires earning credibility daily, with the share price serving as a daily scorecard. In an April 2024 appearance on the Builders podcast, Mandel-Brehm recounted his background and the company’s pivot to regulatory RNAs, including a decision to halt all ongoing projects in March to focus on this area when the company had about 35 employees and no data. He described the company’s work as operating at the intersection of technology and biology, drawing on research from co-founder Rick Young at the Whitehead Institute. He also shared his perspective on company culture, defining it as a set of actions and virtues rather than written values, and mentioned that CAMP4 conducts annual surveys to assess its culture.
