Foursite & Remodroom: Because interior designers kept losing clients at “let me think about it”

Hi all.

I’m a co-founder of VirtualSpaces.

Would welcome any feedback from designers, architects, builders, and homeowners here.

Short background: my co-founder and I are technologists. Neither of us trained in interior design. We fell into this space the way a lot of infra builders do; we watched a market operate around a problem nobody had named clearly.

The problem: in residential design, most deals don’t die because the design is bad. They die because the client can’t picture it.

A homeowner looks at a 2D floor plan and tries to imagine the space. They can’t. The designer is fluent in floor plans; the client isn’t. That mismatch shows up as “let me think about it,” and the lead never comes back.

We built VirtualSpaces to close that gap, on both sides:

•       Foursite converts 2D floor plans and Blueprints into photorealistic 3D interior environments. Purpose-built for floor plan to 3D and blueprint to 3D conversion, with dimension accuracy, material swaps, and style direction.

•       Remodroom works from a single photo of an existing room. The AI handles AI virtual staging and AI interior décor redesigns around what is already in the frame. Furniture, walls, floors, ceiling: recognized and swappable, without re-rendering the whole space.

What we’ve heard from users so far:

•       Designers who show AI 3D visualization in the first consultation close more contracts, faster.

•       Agents using interior design photoreal renders in listings see stronger engagement per square foot.

•       Architects use Foursite to present early schemes that are actually legible to a homeowner.

•       Developers producing pre-sales collateral from Blueprints and 2D floor plans get to market sooner.

We tried to keep the platform portable. Foursite exports in .GLTF, so if a studio wants to refine a specific frame in Blender, 3ds Max, or Unity, they can.

We built this because we believe interior design 3D visualization should be a layer under the industry, not a cost center sitting next to it. The residential design and décor category is enormous and almost entirely still handing files back and forth through render studios; we want to make that motion disappear.

Would love feedback from this community, especially designers, builders, and the occasional homeowner who has been through a renovation and knows exactly why this matters.
