William Janetschek
Co-Founder, COO · Operations, buildout delivery
William co-founded Nomad Group and runs its operations side: once a lease is signed, he is the reason the buildout lands on schedule and on budget. Design reviews, permits, contractors, punch lists, the unglamorous middle of getting a team into its space, all of it reports to him.
Across 300+ New York office projects, his job has been to make the part tenants dread, the gap between signing and moving in, feel routine. If your timeline is tight, he is the person who tells you honestly what is possible and then makes it happen.
