“RXR has been an incredible partner to us, and our growth within their portfolio at 530 Fifth Ave. and 75 Rockefeller Plaza is a testament to the breadth and depth of our relationship,” says Ryan Simonetti, CEO and co-founder of Convene.

In addition to office services, Convene is also making inroads in the flexible co-working space. Although WeWork is clearly the dominant player in that sector, poised to overtake JPMorgan Chase in becoming Manhattan's largest office space occupier, competitors continue to expand.

Convene has leased property for flexible workspaces in Lower Manhattan at Cove Property Group's 101 Greenwich St. and Brookfield's One Liberty Plaza. In July, it secured $152 million in a Series D funding round to support its expansion of space and services. ArrowMark Partners led the funding round, backed by RXR Realty, Brookfield and the Durst Organization. Convene reports its total equity funding to date at $260 million.

Earlier this week, flexible workspace provider Knotel announced four new leases totaling 31,300 square feet in Midtown South. Knotel leased 20,000 square feet from the Moinian Group at 54 W. 22nd St., 147 W. 24th St. and 37 W. 17th St. The company also signed an 11,300 square-foot lease at Elijah Equities' 307 Fifth Ave. Earlier this month, Knotel leased 19,563 square feet at Jack Resnick and Sons' 250 Hudson St. The company has stated it has raised $100 million in funding.

Creative workspace provider Spaces also just announced signing a 110,989 square-foot lease at the Chrysler Building with Tishman Speyer and a lease with the Rockpoint Group for 33,192 square feet at 413 W. 14th St. Earlier this summer, it rented 103,321 square feet at 287 Park Ave. South.

Although losing its bid to lease at One World Trade Center, WeWork had announced it was seeking to raise funds at a $35 billion valuation.
