With the closing of Fund XII, Michael Gladstone was promoted to partner. Michael joined Atlas in 2012 and has been a key contributor to many portfolio companies over the last eight years, including Akero, AVROBIO, Delinia, IFM, and others. “It has been a privilege to work side-by-side with world-class entrepreneurs to build biotechs and pursue new medicines,” said Michael. “I am thrilled to play a role in the next generation of biotech startups as a partner at Atlas.”

Atlas Venture has been building and investing in innovative biotechnology startups for more than two decades. “Michael has been an outstanding team member and company-builder, and we are proud to announce his promotion to partner,” said Atlas partner Jason Rhodes. “We could not be more excited for the future of Atlas and look forward to building companies that will drive therapeutic innovation for patients.”
