Global insurance firm Marsh, a subsidiary of New York-headquartered Marsh & McLennan Cos. has signed a lease for about 25,000 square feet of office space at 830 Brickell. Boca Raton partner David Itskovich represented the landlord, Miami-based OKO Group and London-headquartered Cain International.

The insurance brokerage and risk management company will take up nearly two floors at the tower, where asking rents are above $100 a square foot.

Marsh will join a roster of other notable companies that have signed leases there, including Microsoft Corp., which plans to make it a regional hub after moving its Latin America team to the space by mid-2023; AerCap, which bills itself as the world’s largest aircraft leasing company; Toronto-based CI Financial, one of Canada’s largest global asset and wealth management companies; and Chicago-based private equity giant Thoma Bravo. Itskovich also assisted the landlord in those lease agreements.
