Fintech startup Ramp has expanded its presence at 28-40 West 23rd Street in Manhattan’s Flatiron District, doubling its space to 132,000 square feet. The expansion includes a direct lease for an additional 66,000 square feet, transitioning from its previous sublease with Microsoft. The 10-year lease agreement’s rent details were undisclosed, though the Midtown South submarket averages $84.50 per square foot. The building, owned by Williams Equities, recently received a $155 million loan for upgrades. Ramp provides corporate credit card and cost-cutting services. Other tenants include Home Depot and Estee Lauder’s Aramis brand.
