SOSV

O’Sullivan is founding and managing general partner of the Princeton-based multistage deep tech investor SOSV, which launched in 1995 and has grown into a global powerhouse.

And 2024 was another year of notable achievements and continued growth.

In April, SOSV closed its $306 million SOSV V fund – the firm’s largest to date. The fund focuses on deep tech startups in human and planetary health with an emphasis on the intertwined imperatives of decarbonization and re-industrialization, as well as a mandate to “reinvent the means of production.”

“This new fund will enable an enormous amount of positive change for humanity,” said O’Sullivan.

And later that month, the ribbon was cut on HAX in Newark, an exciting startup development program targeting pre-seed hard tech companies, which SOSV operates with the State of New Jersey as a partner in the venture.

“It is the perfect location – not the least because SOSV with NJEDA’s backing, has been able to build an incredibly well-equipped and staffed facility that is attracting exactly the type of founder we want to back,” said O’Sullivan.
