Tenants
View The Space takes a long and painful process and makes it efficient and enjoyable. Our engaging tool enables you to collaborate with your broker and tour more properties together, from anywhere in the world.

Have your broker send over the VTS Digital Tour to preview the potential spaces before physically traveling to see them in person – stop guessing and qualify each space beforehand
Once you have narrowed down your final options, easily share the VTS Digital Tour with your colleagues to reach a consensus and make the decision faster

They've already got some pretty big names using the service, including property owners Boston Properties, Brookfield, Equity Office and Silverstein, as well as brokerage firms Jones Lang LaSalle and Cushman & Wakefield.

While they are certainly different from one another, the closest thing we've seen to View The Space is Flyer.io. It looks like View The Space is focused on NYC right now, so brokers, owners and tenants have Flyer.io as their only, but still very good option for creating a web-based property flyer and virtual tour.
