Croatian-American immunologist and venture capitalist who served as Chief Science Advisor to Bill Gates and the Bill & Melinda Gates Foundation. Nikolic was introduced to Jeffrey Epstein by Melanie Walker, and the two developed a friendship. Nikolic facilitated the first meeting between Bill Gates and Epstein at Epstein's Manhattan townhouse in 2010. He was controversially named as a fallback executor in Epstein's will, signed just two days before Epstein's death in August 2019 - a designation Nikolic publicly disavowed through a spokesperson, stating he was 'shocked' and would not serve. Nikolic later co-founded Biomatics Capital, a healthcare-focused venture capital firm in Seattle.
Documents from Dataset 11 confirm Nikolic was in active, friendly communication with Epstein as late as March 2019 - just four months before Epstein's arrest. In an email dated March 3, 2019 (EFTA02632987), Nikolic wrote to Epstein: "Please let me know when you know. Would love to see you. How are you?"

Background
Boris Nikolic is a Croatian-American immunologist and venture capitalist who served as Chief Science Advisor to Bill Gates and the Bill & Melinda Gates Foundation. He later co-founded Biomatics Capital, a healthcare-focused venture capital firm based in Seattle. His professional email signature in correspondence with Jeffrey Epstein identified him as affiliated with 'bgC3,' a reference to Gates's private office.
Nikolic's name entered widespread public consciousness in August 2019 when it emerged that Jeffrey Epstein had named him as successor executor in his last will and testament, signed just two days before Epstein's death. Nikolic publicly distanced himself from this designation, with reports indicating he was 'shocked' by the inclusion. Prior to this revelation, documentary evidence shows Nikolic maintained a sustained personal and professional correspondence with Epstein spanning at least 2010 through 2016.
Nikolic occupied a unique position at the intersection of the Gates Foundation's science portfolio and Epstein's social network. Email records show him exchanging messages with Epstein on topics ranging from high-profile social introductions and charity gala logistics to nanosatellite technology, global health policy, and fundraising for his own venture capital fund.
Epstein Connection
Documentary evidence establishes a sustained personal relationship between Boris Nikolic and Jeffrey Epstein spanning at least January 2010 through July 2016. Their correspondence, preserved in dozens of email exchanges, reveals Nikolic communicated with Epstein on a wide range of subjects: coordinating social meetings, sharing news articles, discussing art and design preferences, forwarding policy information, and soliciting Epstein's help sourcing limited partners for Nikolic's Biomatics Capital fund. Nikolic also served as an intermediary for amfAR CEO Kevin Frost in arranging discounted LifeBall charity gala tickets for Epstein in 2012. Most significantly, Epstein's last will and testament -- signed August 8, 2019, two days before his death -- named Nikolic as successor executor of his approximately $577 million estate. Nikolic publicly disavowed this role through a spokesperson, stating he was 'shocked' to learn of the designation.
